PL vertical impact crusher is developed by our company material and material, the material and the metal impact crusher, in 1991 through the national identification of new products four-roll crusher, in 1992 was named national new products, and access to national patent (Patent No. 902 183 745). Widely used in water conservancy and hydropower, refractories, building, highway, railway and other sectors of artificial sand crusher hammer job, especially for granite, basalt, gray, sandstone and other hard, special hard, corrosive materials to He said crusher has more advantages than other types of products. 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%. Breakers can be divided into categories according to medical Crushing and Mining stone crusher. On gravel mining machine principle adapt to massive mine hard rock crushing, the expected size of its typical granite ≤40mm 90% of crusher price, this machine can handle the side length of 100 to 500 mm for the following materials, the compressive strength of up to 350 megabytes Pa, has broken than large, broken after the material was cubic particles and so on. Gravel mining machinery refers Layout of particles larger than three millimeters content more than 50% of the total discharged amount of crushing machinery.
