Crushing ore crusher is an indispensable process equipment, including jaw crusher is particularly famous. Jaw crusher through constant practice and improvement, the structure is substantially the same, but because of jaw crusher has a simple structure, reliable, easy to manufacture, easy maintenance, low cost, etc., so is still widely used in sand, mineral processing, building materials and other fields. Broken jaw in the mine are typically used for hard or medium hard ore coarse broken, the broken, there are crushing in small-scale mining production. Note: This jaw crusher jaw broken commonly known, in fact, both are the same meaning to a crusher equipment. The jaw crusher advantages: crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, low operating costs. Single-stage hammer crusher is suitable for crushing brittle ore general, such as limestone, argillaceous siltstone, shale, gypsum and coal, but also suitable for crushing limestone and clay mixture of Henan roll crusher is widely used in the cement industry . Advantages: crushing ratio, can be broken into chunks of time in line with the original ore into the mill size; compared with the traditional two-stage crushing system, can significantly reduce the time investment and ore crushing costs; simple roll crusher Henan purchase , easy maintenance, and reduce the labor intensity of the workers; crusher discharge size can be designed according to user requirements; hammer work, using new technology casting, wear and impact resistance; grate plate design has been optimized, the material for smooth Henan roll crusher machinery, uniform particle size, stability, long life; airframe seals to solve the dust pollution and body crushing plant ash leakage problems.
