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, and 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 vertical milling machine, easy maintenance, and reduce the labor intensity of the workers; the expected size of the crusher can be designed according to user requirements; work hammer vertical milling machine manufacturers, new technology casting, wear and impact resistance; grate plate design has been optimized , the material smooth vertical milling machine Which is good, uniform particle size, stability, long life; seal body structure to solve the dust pollution and body crushing plant ash leakage problems. PL vertical impact crusher is developed by our company material and material, the material impact crusher with metal vertical milling machine manufacturers, in 1991 through the national identification of new products in 1992 he was named national new products and access National Patent (Patent No. 902 183 745). Widely used in water conservancy and hydropower, refractories, building, highway, railway and other sectors of artificial sand operations, especially for granite, basalt, gray, sandstone and other hard, special hard, corrosive materials, the ratio of other type of product has more advantages. In terms of artificial sand, its crushing capacity far beyond other similar products, is the most ideal artificial sand equipment. PL vertical impact crusher is that it has a unique rotor design, wear-resistant materials technology, broken speed optimization and hydraulic design the perfect combination. Is a professional crushing technology and mechanical model of the perfect combination, are fully reflected in new technologies, new processes. The machine can achieve "stone at stone (PL)" and "stone blacksmith (PLST)" ingenious conversion. "Stone at stone" type for machining hard materials, sand production rate of about 40%; "stone blacksmith" type used in the processing of hard materials, sand production rate of 40% to 60%.
