coal crusher structure properties

The principle and structure of coal crusher is composed of a cylinder body, a cone and an air inlet pipe, an exhaust pipe etc.. Dust containing gas from inlet guide device to cut into the coal catcher, and along the inner wall of the barrel body rotate falling. This stock backspin airflow cone top most arrived, flow turning steering, discharged from the exhaust pipe.

In the air flow from the top down and from the rotation process upward, the coal under the centrifugal force, was thrown to the cylinder body and the inner wall of the cone, and fall into the hopper in the thrust and particle rotary flow itself under the action of gravity. 2, the performance of coal removal efficiency.

Generally 75% ~ 85%, and is affected by the following factors: 1) the population flow. Too large, increased wear, increased pressure loss; too small to affect the efficiency of, generally use 12 ~ 20m/s. 2) the size of structure. The cylinder and the exhaust pipe diameter decreases, properly lengthened cone, can improve the coal collection efficiency. 3) coal particle size and density. The particle size and density is bigger, the centrifugal force is bigger, the coal removal efficiency is also higher. 4) precipitator rigor. When the coal hopper is lax and leakage of air, due to the bottom of the cone is in a negative pressure state, flow will have been put into ash hopper coal back, the coal removal efficiency decrease.
