In recent years, the constant fall of the coal Vertical Mill Brand price has become an important topic that all sectors of society concern, so that reducing the production cost and improving the market competition of coal companies are top priority of the development of the companies. In the coal processing industry, the mechanical equipment used in the medium crushing and fine crushing procedures, especially the wide application of roll crusher in the coal industry conforms to the development needs of the coal industry, and technical advantages of roll crusher in the future development of the coal industry becomes more and more obvious.
Roll crusher has many names such as roller crusher, double-roller crusher and double-geared roller crusher. Roll crusher is a crushing machine making use of the frictional forces of the roller surface to bite the materials to the crushing area and bend, split and crush the materials. When used for coarse crushing or it needs to increase the crushing ratio, tooth or groove will be cut on the roller surface to increase the splitting force.
Roll Crusher Working Principle
The materials to be crushed fall from the feeding mouth to the space between the two rolls, after being squeezed and crushed, the final products will naturally fall. When there are too hard materials or materials that cannot be crushed, the rolls of the roller crusher will automatically withdraw under the effect of hydraulic cylinder or spring to increase the gap between the rolls, and the too hard materials or the materials that cannot be crushed will fall down, thus protecting the machine from being damaged. There is a certain gap between the two rolls that rotate at the opposite direction, and the maximum discharging granularity of the final products can be controlled by changing this gap. Double roll crusher crushes the materials by relying on the two round rollers rotating at the opposite direction, and four-roll crusher crushes the materials by relying on the two pairs of round rollers rotating at the opposite direction.
