As we all know, mobile crusher is crushing and screening production lines composed of jaw crusher, cone crusher, vibrating feeder, vibrating screen is the main equipment. Spring cone crusher mobile crusher for crushing construction waste treatment effect than ordinary cone crusher is very prominent.
1.Cone crusher working note: Mine must be allocated to the plate in the middle , forbidding the mine goes into the crushing cavity directly. Because it is easy to make crusher overload and the liner wear unevenly . The condition of giving mine:
a. Mine evenly was distributed in the crushing cavity through the distribution plate. b. Feeding ore can't higher than the level of rolling acetabular wall. The crusher to the maximum size of giving mine couldn't be allowed equal to the mine mouth size ( the maximum size of giving mine = 85% to the mine mouth size) ,or they will lead to : a. Crushers yield reduced. b. Damage to certain parts of the crusher.
2.Crushers are not allowed to start overloading , because the overload will start the accident. When the crusher will finish the work,at first we must stop to the mining machine . When crushing the mine goes into the crushing cavity after discharge ,it can make crusher stop.Crusher should be always checking the pressure and hydraulic locking system work station , once we identify problems and handling in time .

3. Crushers' output Crushers' output, and feeding methods , feeding degradation, platoon ore blocks degrees size,mechanical properties, temperature and so on . Varies greatly,the manufacturer of a given output is sketchy the quantity in the specified conditions.
4. The replacement of rolling acetabular wall. Rolling acetabular wall with U shape screws embedded in the adjustment of the ring, both between infusing zinc alloy and making closely. New installation or the replacement of rolling acetabular wall, in the work six to eight hours we should check for tightening situation ,and once again tighten the u-shaped screw.
Broken construction waste, on the one hand, from the city environmental protection considerations, to meet the state building on the city”s waste disposal regulations, which requires the use of crusher itself should have eco-friendly features, the production process should be reduced noise, pollution, reduce dust, and many other factors, a reasonable solution; the other hand, the pace of urbanization process is still accelerating. Construction waste resource utilization of voice getting louder and louder, construction waste crushing capacity requirements is a rigid indexes, crusher capacity is an important upgrading.

Hongxing Hammers at Technology Innovation of Rotary Kiln

In general, there will be crack in the head of the rotary kiln that is the junction of the cylinder and the fixed kiln head and in the kiln tail which is the junction of the cylinder and the fixed smoke chamber. The rotary kiln is in operation under the negative pressure. In order to prevent the outside air from being sucked into the rotary kiln to stabilize the thermal system, it is necessary to install the sealing device in each of the parts mentioned above.
Our company mainly produce rotary kiln for ore dressing,30 years of industry experience to create top quality, Our rotary kiln equipment is trusted by many customers at home and abroad.What should spare Rotary Kiln welding work before?
1.The rotary kiln shell welding work must be qualified in the rotary kiln shell is looking after, and the use of welding gear rotary kiln.
2.Electrode selection: rotary kiln electrode welds to ensure its quality should not be less than the mechanical properties of the base metal mechanical properties, welding process parameters and the specific implementation requirements of the drawings. Drawing no requirements, must develop welding instructions.
3.To participate in the rotary kiln shell welding welder, must pass the examination are allowed to officially participate in the rotary kiln shell welding. Normally two test panels of each welder welding, bending and tensile strength required to intercept test specimens for bending and tensile strength tests. Test panels of material, groove forms, welding processes are the same requirements and formal welding.
4.Used for rotary kiln shell welding electrodes, must be dried before use, in the dry box, the temperature of 250 ~ 300 ℃, drying time is 1 ~ 2h. Dried down to about 150 ℃ temperature preservation, on the insulation tube, used with the check, to avoid staying too long in the air.

5.Before the deal rotary kiln cylinder welding groove in the form, size check, not a groove at the delamination crack, slag and other defects affecting the quality, welded joints before welding on both sides should be 30 ~ 50mm wide paint , rust and other dirt cleaned, exposing metallic luster to start welding.
6.Prior to welding, the rotary kiln gear lubricating roller bearings, roller wipe the surface of debris, with the auxiliary drive slowly turn rotary kiln shell, the welding ground shall not be connected to the rotary kiln tire or wheel on the cable insulation measures should be reliable, have good low welding location lighting, ventilation and insulation. Also, the rotary kiln in welding workers and establish communication links between operators.
If kiln tail has air leakage, it is easy to suck in large amount of the cold air because the kiln tail is the part that has the largest negative pressure, which will make it difficult to discharge large amounts of gas in the rotary kiln so that the fuel cannot be burned completely, resulting in that the thermal system is broken and increasing the fuel consumption as well as reducing the yield of the kiln. At this point, if the operators still want to maintain a certain ratio among the amount of wind, fuel and materials, they need to increase the load of the exhaust fan, which will increase the power consumption. At the same time, because there are powdery materials in the gas and the occasionally down draft will spill a lot of dust, affecting the health of the plant. Therefore, the design requirement of the sealing device of the kiln tail should be higher than that of the kiln head.

Maintenance Technology of Bearing of Sand Maker

The development of artificial sand suits several policies of the govt, and it’s several blessings, for instance, it’s ready to form up for the inadequate provide of the medium and coarse sand within the natural sand resources; it is unnaturally mix the sand grading; the Alimentateur vibrant prix composition of the sand is controlled artificially; numerous tailings and waste stone materials is wont to manufacture the bogus sand. The shortage of sand resources opens wide development space for the popularization and application of artificial sand.
When the sand maker is working, the possible reasons why the bearing becomes warm are lack of oil, dust in the machine and damage of the bearing. The elimination methods are to add oil or cleanse the bearing and change new bearing. After the fine crushing of the sand maker and the drying process of the kiln machine, the grinding mill also plays an important role, so that the correct operation of the grinding mill is also important.
Sand maker is suitable for crushing and reshaping soft, medium-hard and super-hard materials, and it is widely used in all kinds of kiln machine rocks, cement, refractory materials, iron, glasses, artificial sand and stone and all kinds of metallurgical residues, and it has higher production capacity in producing silicon carbide and bauxite and other high-hard and super-hard materials and abrasive-resisting materials. Sand maker is widely used in the pre-phase in the grinding process, and it will produce large quantities of powder rocks and reduce the grinding load whose cost is extremely high. Among the mechanical equipment, it turns to the impacting and grinding effects of the medium and the rocks themselves, makes the granularity of the rocks further small until they are ground to powders. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like china sand washers, Henan Hongxing is always doing the best in products and service.conveyor belt: http://www.crusher-machine.com/n146.html
The size of the sand making equipment and the volume of the oil box in the sand making production line are all small, so that the quantity of the lubricant oil is small, and the temperature of the oil during the working process is relatively high, so that it requires that the lubricant oil has higher heat stability and resistance to oxidation. As for some ore beneficiation equipment, especially for some machines in the mine that is easy to have fire and explosion, it requires lubricant with high non-flame property and the flammable mineral oil can never be used. Because the environment of the mines is very bad, there are a lot of coal dust, rock dust and water; the lubricant will inevitably be polluted by these impurities, so that the lubricant oil has to have better antirust, corrosion resistant and anti-emulsification property.

Integrated Process of Industrial Ore Dressing

Ore mined first by the initial jaw crusher broken by the crusher to a reasonable degree of fineness by the elevator after, even into the mill to the mine machine, crushed ore from theball mill grinding. After cleaning and grading of the mineral mixture in through the magnetic separator, due to a variety of different minerals than the susceptibility through magnetic force and mechanical force to the magnetic material mixture to separate. In the minerals to be separated out, as it contains large amounts of water, subject to the initial concentration thickener, and then by drying machine drying, you can get dry minerals. Iron ore beneficiation process is the most commonly used as a dressing process, relatively coarse ore extraction, the process requires more rigorous and meticulous, iron ore beneficiation technology improved, more conducive to the development of China’s steel industry, producing quality products Enhance the process of steel in the international competitiveness and quality, in addition to technical studies, the device also requires constant innovation, optimization, and create new standards.
The production of ore dressing is a complex process, with the transition and transformation of substance and energy. It has the characteristics of time-variation, large lag, complex mechanism and lots of affecting factors, with the performance of consecution in large range, nonlinearity and tight coupling, which is complex and indeterminate.
The product process of raw ores is to sieve the raw ores to the ore fines of 0 to 15mm and ore lumps of over 15mm. the ore fines are sent to the strong magnetic cylindrical ore storage bin by the belt conveyor as the materials of the product of strong magnetic separation. The ore lumps are sent to the bunker in front of the furnace through two-times screening by the belt conveyor as the materials of the roaster. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like mobile jaw crusher, Henan Hongxing is always doing the best in products and service.rock pulverizer: http://www.crusher-machine.com/n217.html
The process of roast working of the shaft furnace is to send the ores to the shaft furnace to be roasted, which can separate the ores to the waste rocks and valuable ores. The waste rocks are sent to the hillock by the belt conveyor and the winching system, while the valuable ores are sent to the weak magnetic cylindrical ores bin as the product of the materials of weak magnetic separation.
The working process of ore grinding and magnetic separation can be divided into the strong magnetic separation and weak magnetic separation. The primary of the ore grinding system is a closed circuit made by the ball mill and the separator, while the secondary is a closed circuit consisting by the ball mill and the water cyclone. The undersize sieves are embodied in both of the two ore grindings to control the particle sizes feeding the secondary from the first separation. The ore fines or the roasted ores are classified by the classifier after grinded by the ball mills.
To ensure the sorting effect, the pulp must have the certain residence time in each flotation cell and the too long time or too short will result in the loss of useful minerals, reducing the operation recovery. Therefore, the specifications of the flotation machine should be in line with the scale of dressing plant.
