Roller grinding mill YM series

verticalfor limestonelarge

Raw materials: - Limestone, calcium carbide, sandstone, coal gangue, gypsum, blast furnace slag, lump coal Max feeding size: - 40mm Application: - cement, coal crushing, mining, desulfurizing in power plant Shipping ports: - Shanghai, Qingdao or Tianjin Delivery: - 15-30 days The YM series of pre-grinding mill is designed with a simple vertical structure and features hierarchical crushing, easy operation, low energy consumption and little dust. It is without sieve plate so the problem of blocking is eliminated. The hammerhead uses a hinge structure making it convenient for replacement. Both the hammerhead and scaleboard are manufactured with highly wear-resistant alloy and feature high strength, high corrosion resistance and long service life. 1.The granularity of feedstock allowed is large (D≤100mm). 2.The granularity of discharged product is small (D D95≤0.9mm). Discharging efficiency is high. It saves more than 25% of electricity. 3.The process flow is easy. The pre-grinding mill occupies little space and saves on civil engineering investment. 4.The wear resistant part has longer service life.
