Jaw Crusher Capacity Parameter

With the exploitation and utilization of mineral resources, nonferrous metals, chemicals, ferrous metallurgy, light industry and other mineral resources become depleted, mining increased significantly, but also the rapid increase in the required building materials, road construction and other industries crushing material, thereby making the crusher growing role. Jaw crusher is a kind of widely used crushing equipment. According to its structural characteristics can be divided into the compound pendulum jaw crusher and Jane put jaw crusher. A crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics.

Jaw Crusher Purpose And Scope

Jaw crusher is mainly used in metallurgy, mining, chemical, cement, construction, refractory and ceramics and other industrial sectors for secondary and tertiary crushing of various ores and rocks with medium hard. Crusher best suited to breaking strength is not higher than 300MPa (MPa) of various hard and soft ores, the largest block of the material to be broken jaw crusher capacity parameter must not be greater than specified. Jaw crusher is widely used in many sectors in mining, smelting, building material, highway, railway, water conservancy and chemical industries, breaking strength not exceeding 320 MPa of various materials.

Jaw crusher structure: static jaw, side guard pull, movable jaw plate, pulleys, eccentric shaft, push pull, as well as motor and belt adjustment block composition. The main jaw crusher wear parts are: jaw, and consumption is great. Therefore, improving the life of jaw plate is very important. And improve the life of jaw, the key is to analyze the conditions and wear mechanisms of its work, a reasonable choice jaw material according to working conditions. Common jaw plate material, there are four: high manganese steel, manganese steel, high chromium cast iron and high manganese steel composite, low-alloy steel.

Jaw Crusher Operation And Maintenance

To ensure the normal operation of jaw crusher, in addition to proper operation, the need for planned maintenance, pay attention to jaw crusher capacity parameter, including routine maintenance checks, minor repairs, repair and overhaul. Jaw crusher minor repairs, the main contents include inspection and repair adjusting unit that adjusts the discharge port clearance, for a U-turn or replace the liner wear, check the transmission parts, lubrication system in a timely manner with the change lubricants, small repair period is 1 to 3 months. Jaw crusher repair, except for small repair work, including replacement of the thrust plate, lining, inspection and repair such as Bush. The repair cycle is generally about 1 to 2 years. Jaw crusher overhaul, in addition to the repair work, but also includes replacement and turning the eccentric shaft and jaw mandrel rod casting babbitt head portion, a replacement or repair worn parts. Overhaul cycle is generally about 5 years.
