The clearance between the two rollers can be adjusted to change the sizes of final products. The smooth roll crusher can be classified into double roll crusher and four roller crusher according to the roller quantity. The double roll crusher bears the features of stable operation, easy maintenance, low cost, output size adjustable. The double roll crusher can be used in the processing of fragile materials in cement, metallurgy, chemical, power generation, coal industries and so on.
Roll crusher is also called roller crusher, which is suitable for the coarse and medium crushing of brittle bulk materials in cement industry, chemical industry, electric power industry, mine industry, metallurgy industry, building materials industry, refractory materials industry and coal industry. It has large feeding particle size and adjustable particle size, which can process materials with 160MPa or less than 160MPa compressive strength. Especially in coal industry, roller crusher can directly crush raw coal after the removal of iron and impurity without removing the waste. The finished materials have uniform particle size, low over crushing ratio, so as to simplify the separation process as well as reduce the investment and production costs.
