Introduction to Roll Crusher:
Dajia roll crushers can be referred to as compression-type crushers. .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, chamicals, and industrial production of building materials, among others.
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 crushers, when considering the volume of production and maintainance costs. However, roll crushers 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.
The oretically speaking, the maximum reduction ratio of roll crushers is 4: 1. For example, the smallest size that can be recognized by a particle OS 2inches is 1/2 an inch. Using this machine, a material is crushed and reduced to a minimum particle size of 10Mesh (2mm). 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.
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.
Features and Applications of Roll Crusher
Roll crushers 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 crushers are mostly used during coal mining. The crushers 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 crushers are capable of producing between 100 and 120 million bricks per year. They are widely used in the production of facing bricks, paving bricks, hollow and thermal bricks.
