MLS type (original MPS type) vertical roller mill produced by North Heavy Industries Group Co., Ltd. Cement Equipment Branch is the efficient and energy saving grinding equipment widely applied in the production of raw material in cement industry.
In this context, Erkan et al. (2012) in their study compared the wear rates of rodball mill circuit with VRM and concluded that VRM technology reduced overall wear rate of the grinding process from 2.73 kg/t to 0.8 kg/t. This study contributes to the literature related with VRM by conducting pilot scale test studies with a mobile plant.
Ideally, you should observe roller mill tests of your material in the mill manufacturer’s plant. The tests will help determine not only the best roll surface, roll speed ratio, and roll gap for your application, but the ideal number of roll pairs, motor size, feeding device, and other options. Expect the tests to demonstrate that the roller
Vertical roller mills are widely used in the concrete and mining fields, and are also used to process coal，lime and gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials. Capacity: 50250 t/
The coal vertical roller mill has less dust, low noise, high efficiency granular composition, and excellent combustion performance due to its special design and structure Chaeng(Great wall machinery) Vertical
The vertical works according to the principle of layer material to powder. Low energy, the powder consumption of vertical mill is 20%30% less than that of ball mill. With the incensement of moisture of the raw material, the powder consumption will decrease obviously. The vertical mill saves 30%40% of energy consumption compared to the ball
