Jaw crusher is the crushing equipment appeared earlier, because of simple structure, rugged, reliable, easy to maintain and repair as well as less production and construction costs, and therefore, until now still widely in metallurgy, chemical industry, building materials, electricity, transportation and other industrial sectors, for breaking strength at 147 ~ 245 MPa of various ores and rocks of coarse, medium, fine. In recent years, I plant to meet the metallurgical, mining, construction and other industrial sectors crushing high strength, high hardness, low carbon ferrochrome needs, specially developed strong jaw crusher.
Jaw Crusher Use: jaw crusher is mainly used for a variety of ores and medium-grained bulk materials crushing, is widely used in mining, smelting, building material, highway, railway ballast stone, water conservancy and chemical industries.
Jaw Crusher Features: crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, low operating costs.
Jaw crusher works: When working, the motor pulley driven by the eccentric shaft rotates to move the jaw cycle close, leaving the fixed jaw, and thus the materials are squeezed, rubbing, grinding, such as multiple broken, so that the material into small, gradually fall until discharged from the discharge port.
How to buy jaw crusher, YiFan Machinery give you the most sincere advice:
1, the choice of jaw crusher feed size is to look at the principles and grain size of the discharge decision into Liaoduo large, coarse granularity, choose super coarse type or coarse type, whereas the medium and fine type. When calculating feed size, with open side by multiplying the maximum feed size of 0.85 as an alternative feed size based on the average size of the product is divided by the maximum feed crushing ratio.
2, the choice of jaw crusher liner, the user typically must consider three factors: production, power consumption, liner wear; generally according to the following principles: maximum feed size; changing particle size, feeding the hardness of the material;; particle size distribution of the wear resistance of materials.
3 , jaw crusher liners longer the power consumption is higher, hard to choose a short liner materials , soft materials selected long- liners in the distribution of materials, thin lining material to choose a short , thick material selected long- liner.
4 , jaw crusher feed on grain size distribution , in general , less than the closed side of the discharge port of the material can not be more than 10% , if more than 10%, the power consumption increased granularity becomes flaky.
5 , the amount of increase in the viscosity of the material moisture content can affect the throughput of the material , the material on the water , it is generally not more than 5% . The use of power : the standard jaw crusher should reach 75% to 80% , short head jaw crusher should reach 80% to 85%.
6 , jaw crusher because of its use in harsh environments , dust, coupled with some using the unit maintenance is not in place , a variety of problems often arise in the operation , in general, the use of jaw crusher operation should note the following question , in order to ensure the normal operation of the machine .
7 , jaw crusher at work , feeding should be uniform, not segregation. If feeding inequality appears to reduce production capacity , product size is too large, spring- action frequently, bowl-shaped bearing pressure, power consumption rises. Have iron device to prevent the crushing chamber through the iron, iron if too frequently , it may cause broken shaft accident.
