Exploring Methods to Extend Use of Sand Maker

Aerated concrete products in foreign countries and now have nearly a hundred years of history, has become a pillar industry in construction industry. China's introduction of aerated concrete technology nearly four decades of history, its production technology and equipment and equipment to mature. Because of aerated concrete with light density, high performance thermal insulation, sound absorption effects, can be processed and so on.Aerated concrete rich in raw materials, particularly the use of fly ash as raw material, which can be comprehensive utilization of industrial wastes, environmental pollution, does not destroy the land, but also to create a good social and economic benefits, is an ideal alternative to traditional solid clay brick Wall material.
To prolong the service life of sand making machine, there are mainly eight tips:
1. Before operation, inspect whether the observation door of vortex chamber is shut tight to avoid danger.
2. Examine the rotation direction of impeller; impeller should performance anticlockwise rotation.
3. The starting sequence of sand making machine and transportation equipment: discharge sand making machine feeding; crushers must be started without load, and feeding can be carried out when crushers run normally. Shutdown sequence and start-up sequence is opposite.

4. Materials whose size exceeds the limit shouldn��t be fed into crushers, otherwise, it may cause the unbalance of impeller or excessive abrasion of impeller, even leading the block of impeller passage.
5. When the discharge equipment stops, feeding should be timely ceased.
6. Materials should be fed evenly and continuously.
7. Fierce vibration and abnormal noise are not allowed during operation.
8. The addition of grease lubrication should make up 1/2-2/3 of bearing chamber; Add proper lubrication grease each time crushers work an hour.
Aerated concrete categories according to raw materials, quality and technical characteristics of major equipment and so on, to take a different process for production. In general, fly ash or silica sand ground into paste with water, add powdered lime, regular cement, plaster and foam, by stirring into the mold box, resting after curing foam, cut into a variety of puzzle Block or plate, keep a car from the steam into the autoclave, in the high-temperature steam curing in that the formation of saturated porous lightweight aerated concrete products.In the exact production site, we can choose suitable cement grinding mill according to the exact requirement and material information. This procedure is almost the last process of cement production. So cement grinding will directly influence the products quality.

The Usage of Dry Powder in Sand Maker Machine

The granularity of stone enters concrete sand making machine though belt conveyor. Stones will be crushed by hitting other stones. Material falls down to impellor cavity. Under the high speed centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impellor and shell, and hit each other several times, finally the smaller stone comes out from the bottom, and goes to vibrating screen. The qualified materials will be transported to sand washing machine, however unqualified materials will return to concrete sand making machine to be crushed again. Output sizes can be made according to customer’s requirement. If input size is larger than the designed size, other crushing equipment will be necessary.
Dry powder mortar is mainly processed by sand making machine, and the general raw materials of dry powder mortar include: granite, natural river gravel, andesite, rhyolite, diorite, sandstone and limestone. And the strength of the finished sand is different according to different kinds' of rock. The mining equipments processing the mechanism sand mainly include: vertical shaft impact crusher, impact crusher, cone crusher, sand making machine, which they all have their own characteristics and uses. Sand making machine has a significant advantage in processing dry powder mortar.
Dry powder mortar is actually the polymer dry mixed mortar or the prefabricated mortar of dry powder and also is one of the main material of cement and gypsum. According to the requirement of different building function, it can be directly used as mortar materials after the dry powder mortar mixed with dry powder of building aggregate and additives according to a certain proportion. The dry mortar is generally used in producing:dry tile adhesive, dry powder wall painting, dry powder wall motar, dry powder mortar concrete and so on.

Stretchy Principle Analysis of shaking table

Shaking table is gravity beneficiation equipment for fine materials and widely used in selection of tin, tungsten, gold, silver, lead, zinc, tantalum, niobium, iron, manganese, ferrotitanium and coal. Our company has long history of shaking table production and persists on constant innovation. We develop hyperbolic wave surface shaking table on basis of single wave surface shaking table and the initial straight surface shaking table, whose handling capacity, recovery rate and concentration ratio has been significantly increased.
Spring bed of shaking table is mainly composed of inertial vibrating device anddifferential mechanism with elastic collisions. Inertial vibrating device mainly consists of the eccentric wheel, spring piece and suspension spring etc. Its role is to make the surface of bed produce reciprocating motion. Differential mechanism mainly composes by the soft spring, hard spring, spring seat and blow plate etc. It can make the surface of bed emerge differential movement.
When eccentric wheel turns, suspension spring slightly do up and down movement to make the pulley and belt keep tension. The spring does before and after exercise, this will drive the surface of bed to do reciprocating motion. When the table surface moves back. There will be a distance (or stroke length) between the spring seat and strike board, and at the same time, soft spring is compressed. At the end of the process, strike board strongly touches with spring seat, it will make ore grains which are on the bed surface get big inertia force, so mineral grain does forward movement. After blow plate strikes with spring seat, the bed surface immediately is rebound, so that the early stages of the trip gets a great acceleration, and mineral grains continue to move forward. Therefore, the asymmetry structure of the head is more than the former two, especially suitable for processing granule materials.

For the stroke of spring bed, we can adjust in 5 ~ between 25 mm. The adjustment method: (1) Adjusting large stroke: we can control the eccentric eccentricity to achieve, the eccentricity is big , so the stroke is big; The eccentricity is few, the stroke is small; (2) Adjusting small stroke: we can adjust reasonable degree of the soft spring to realize; In a certain range, the soft spring tightens, the stroke is big, soft spring is back to loose, the stroke is small. We often use this method in the operation.
Through production practice test, a bed of spring have made the following some improvement: use a rubber spring instead of steel hard spring, reducing the noise; In the spring of rocker instead, reduces the cost; The motor modification in partiality axis above, the triangle with transmission belt instead of suspension spring, and up with reduced up, prevents motor damp, and do not produce resonance phenomenon; With spring box instead of the spring seat, compact structure, convenient maintenance.
Shaking Table is a gravity concentration equipment used for sorting of fine materials, and now is widely used in sorting tin, tungsten, gold, silver, lead, zinc, tantalum, niobium, iron, manganese, titanium-iron and coal.

Vast Technology Improvement of Impact Crusher

The crushing operation is divided into a variety of modes of action. The common operation is crushed, split, broken and grinding stripping, etc. Different mode of action will have different considerations. Compressive strength of the ore should be considered during crushing. Mineral tensile strength need to pay attention to splitting the materials. The bending strength of the ore should be considered in the broken operation. The shear strength has become the main consideration in grinding stripping ore. The impact crusher is a crushing equipment which sets above a variety of forces repeatedly on mine. Its impact strength should be seriously considered because it has a certain impact effect.
Traditionally, the impact crusher is one of the crusher specially used in burning lime. Although the impact crusher is with the characteristics of big crushing ratio, the wearing parts is easily worn owning to the impact of the plate hammer, which causes the increasing cost of wearing parts as well as the reduction of the crushing amount. As with this phenomenon, Zhengzhou wear-resistant materials research institute make efforts to upgrade the technology of the board hammer, impact scaleboard and other components.
As we all know, the worn of the impact crusher plate hammer only appeares in the side facing materials. When the rotor rotate at a normal speed, the feeding materials will fall to the board surface of the plate hammer, it won't be worn the plate hammer back and flanks, even the side facing material wear also rarely. But when the rotor rotate at an abnormal speed, the plate hammer will be worn easily.

The former board hammers are usually made from high manganese steel, which is suitable for crushing materials with medium hardness, but when it crush such as basalt, diabase, biotite, granite and other high hardness materials, the plate hammer must have good corrosion resistance as well as high wear resistance. Nowadays, the generally used plate hammer is mainly made by high chromium cast iron, and high chromium content means relatively good toughness. However, high chromium cast iron brittle and its high price promotes the continuously research of new wear-resistant materials.
Reportedly, after many experiments as with the crushing characteristics of impact crusher, reasonable application the most advanced nanotechnology, experts of Zhengzhou Materials Institute has developed the new casting wear-resistant materials whose sexual price is at present 1-2 times higher than the general materials, which compared with similar imported products, semi solid extrusion hypereutectic high chromium plate hammer has the advantages of high security, high wear resistance, low in price and greatly shortened delivery cycle.
Impact Crusher is the first choice of crushing in stone crushing line. The Impact Crusher is widely applied in mining, transportation, energy, construction and chemical industry. For crushing and screening, it's better choice. The most outstanding advantage of Impact Crusher Machine is that its finished powder is in good, cubic shape and without tensility and cranny. Our impact crushing equipments are accurate, reliableand and have perfect performance. We manufacture and supply portable, stationary impact crushing plants and equipments.

The Ways to Select Befitting Sand Making Machine

Sand is manufactured from ‘Grit’, which is by product of stone crusher. While crushing, the size below 6mm is manufactured, which is sieved and separated from the metal. It is not used much in the construction industries. The consumption of the “grit” is very less compared to the production. Hence, it is available at very cheap rate. The sand plant is specially designed for manufacturing sand from the grit. It is a better utilization of the material.
We should depend on the different materials to choose the different sand making machine, now we teach you how to choose the suitable sand making machine.

Applying Items on the Common Ball MIll

Energy saving and consumption reduction have always been the request for industrial production. In particular, once the heavy-duty industrial equipment like ball mill runs, the consumption will be extremely huge. Responding to this situation, in order to meet the social demand and improve the environment, Henan Hongxing Mining Machinery Co., Ltd. has constantly upgraded and researched the technology of ball mill, and finally successfully develops a new generation of high-efficiency and energy-saving ball mill.
As we all know, there are various kinds of mediums in the world. For example, the stainless steel must be spark-resistant, non-magnetic steel in the 300-series. Alloys 304 and 316 are the most common stainless steels. However, high-density alumina ceramic medium is one of the most widely used medium in ball mill. Nowadays, people pay more attention to the safety of anything. What i want to emphasize is that there is an ongoing discussion and debate about what is the 'safest' medium used in ball mill.
Every medium has both advantages and disadvantages. Once the milling mixed compositions like black powder is mixed in the mill that the dangers arise. It is obvious that we don't want sparks generated in the ball mill during the process. Ceramic is hard, and it does not easily wear out, but some kinds of ceramic do generate spark. And some people have proved that when pieces of ceramic medium collide each other in the dark, little sparks can be seen. Others say that there is just little luminous sparks and they don't think it a danger in milling.

Lead or brass is reliably the only really spark-free medium and is regarded as the standard for milling comps like BP. But lead is soft and will wear down just a while. And it is also easy to lead a Lead poisoning. At the same time, there are many reports about lead poisoning recently, so we should take serious. Lead medium probably will continue to be used more than any other mediums in amateur pyrotechnic milling.
Comprehensive intro to Ball Mill: Ball mills are extensively applied in mining, constructing material, smelting, road and chemical. It may be the crucial gear for grinding following the crush process. Energy-Saving Ball Mill Features: one It can be an effective device for grinding a great deal of difficult components into good powder; two There are two methods of grinding: the dried out way and also the wet way; three might be divided into tabular sort and flowing sort based on diverse expelling mine; four to utilize the ball mill, the materials being soil is loaded to the neoprene barrel that consists of grinding media; five since the barrel rotates, the materials is crushed among the personal pieces of grinding mass media that combination and ball mill crush the item into good powder more than a period of time of time.
In one word, nothing is perfect. Any thing has both advantages and disadvantages. We should take good use of its advantages and avoid its disadvantages.

Vibrating Screen Make Quartz Become Sand

With our vibrating screening equipment , you'll be able to separate sizes products. Such a scenario is mainly because of the overcapacity of construction machinery manufacturing - Rock cone crusher coupled with changes available in the market such as the velocity cut of high-speed rail construction the complete completion of large-scale infrastructure along with the pressure brought the actual entrance and garrison of well-known manufacturers. All of make the crisis of construction machinery manufacturing. Jaw crushers are generally used as primary crushers, or even action inside the strategy of reducing rock, are among the many main sorts of primary crushers in a very mine or oreprocessing plant. This feature allows the passage of a good material direct to the discharge conveyors, in order that it lets you do not pass through the Jaw Crusher feed opening.Mtm Trapezium Mill
Quartz sand is mainly used in the manufacture of glass, refractories, smelting ferrosilicon, metallurgical flux, ceramics, abrasive materials, casting, etc. Generally speaking, there are two methods of making quartz sand. No matter use which method, the vibrating screen is the necessary screening equipment.
1. Dry process making quartz sand, the major equipments used in the process generally include vibrating, crushing machine, grinding machine, etc.
Quartz stone ore will be processed into smaller stones by using crushing machine, which will grinding into sand particles by the grinding machine, and then screened by vibrating screen and the last is storage and packaging.
The quartz sand made by dry process is classified into three grads: ordinary quartz sand, semi refined quartz sand, refined quartz sand. Because the quartz stone aggregate is with fulvous surface mined from the hills. The products made by the picked out small quartz stone ore belongs to the ordinary quartz sand, the advantage of which is cheap and the disadvantage is with more impurities, so they are mostly used in the construction industry. Pick out the larger quartz ore will be processed into the half refined quartz sand, its apparent appears white with brown spots, the price of which is moderate and the quality is better. It is applied in a wider range. The picked out large aggregate after removing the tawny surface artificially will be processed into the refined quartz sand, its apparent appears white and shiny like white sugar. However, the processing process of the refined quartz sand is time-consuming and inefficient, so the price is higher.

In quartz screening line,the extracted sand and quartz pebble (which is separated on extraction based on colour, ie. either “white” or “gold”) is placed within the raw feed stockpile area from which it is loaded into a hopper and conveyed to a primary screen to separate oversize ( 50mm material) from the quartz pebble (5mm to 50mm material) and 5mm quartz pebble and sand. 5mm to 50mm Quartz Pebble Washing and Screening From the primary screen, the quartz pebble is transferred to a log washer where water is added and through vibration, additional sand and5mm quartz pebble is removed. The water,5mm quartz pebble and sand is transferred to the main wash tank for further washing and sorting. The washed pebble is then passed over a dewatering screen. The water from the dewatering screen is recycled for use within a twin deck sorting screen used to separate the 5mm, 8mm, 14mm, 20mm and 40mm quartz pebble products as well as any remaining oversize material.
