Minggong roll crusher can be referred to as compression-type crusher. In the mining industry, they are used to crush mines of medium or low hardness, rocks that have low or medium rigidity during mine selection, for cement, chemicals, and industrial production of building materials, among others.

Roll crusher have the advantage of producing an end-product that is has a fine size distribution and they produce little dust or fines during operation. They are widely used for crushing minerals whose abrasive levels are low and in the small scale production of mine. Roll crusher are mostly used during coal mining. The crusher used may either be single roll or double roll. When used in coal mining, the surface of the rolls will have teeth or raised forms (when used for minerald and metal ores, the rolls have a smooth surface).

The roll crusher are capable of producing between **0 and **0 million bricks per year. They are widely used in the production of facing bricks, paving bricks, hollow and thermal bricks.

However, their use in the mining industry has greatly declined due to their inability to produce large amounts of output. In mining applications, the roll crusher does not match up to cone crusher, when considering the volume of production and maintainance costs. However, roll crusher have the advantage of producing a close distribution of the product size. In cases where the ore is not very abrasive, the maintainance costs are significantly reduced.

Theoretically speaking, the maximum reduction ratio of roll crusher is 4: 1. The materials are crushed by compression between two rolls rotating about a shaft. The size between the two rools used for compression can be suitably adjusted according to the desired size of the end-product. It is important to note that the largest particle size of the materilas inserted should not be more than four times the dimension of the gap.

Working Principle

The rotation of the two rolls draws the particles to be crushed into the gap forming a friction angle between the rolls and particles referred to as nip angle. Through forcing the materials between the gap, the rolls create compressive forces causing the materials to fracture.
