The Maintenance Skill of Double Roller Crusher

There are many kinds of minerals. Based on the nature of mineral and industry uses, ores are classified into metal ore, nonmetalliferous ore and flammable machine rock. According to the types of metal containing, ores can be divided into the single metal ore, multi-metal composite ore. Ore mining usually through the following steps: crushing and screening, grinding and classification, material separation, concentrates and residue processing, dressing conduction, etc.
Double roller crusher needs to maintentence the roller surface in the running process.
Light face roll crusher sometimes on the frame with grinding wheel, when roller surface grinding out of the pit or groove, can not pull down roller surface and in the machine for grinding roller surface repair.
Tooth face of roll crusher gear plate or toothed ring can be replaced or switched to use. When teeth wear to a certain, must be replaced or repair, or cause broken uneven, the particle size increase in power consumption, production. Some machine with surfacing device, which can be directly in the machine repaired. Some light face roll crusher rolls with automatic axial reciprocating mobile device, making roller surface wear uniform.
Roller surface wear, discharging mouth width increases, need to adjust to the active roller (single roll crusher is adjusting jaw plate). Adjustment should be paid attention to keep two rolls parallel, prevent skewed. The sliding bearing to roll crusher, should pay attention to roll bearing clearance. Roller bearings and shaft neck of the tip clearance is usually shaft neck the diameter of the 1/10000 ~ 1.5/10000, axle bush's side is the gap between the 1/2-1/3. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like combination crusher, Henan Hongxing is always doing the best in products and service.hydraulic cone crusher:http://www.hx-crusher.com/cone_crusher.html
In order to guarantee the normal work crusher, we need to check the lubricating bearings. Sliding bearing often USES oil cup gasoline or regular into thin oil by artificial, rolling bearing is regular note oil lubrication and seal.
In recent years, with the continuous improvement of the development of production and construction and the technological level, the roll crusher has obtained new development and improvement in the structure and fragmentation mechanism. For example, applications range of the grading crusher and roller press expand rapidly, which has created the conditions for energy saving of the building materials, coal, chemical and mineral processing industries and brought high benefits to the enterprise.
The roller crusher can be divided into single roller, double roller, three roller and four roller according to the number of the rollers. It can be divided into smooth roller, gear roller and groove roller according to the shape of the surface of the roller. In addition, there are profiled roll crusher.
