Coal coal drop tube is an important equipment to ensure reliable coal handling system of coal supply, coal flow in the coal cylinder is conveyed at a certain trajectory, in order to ensure the normal use of reliable coal chute, generally in the coal drop tube of coal flow of coal chute with scour resistant lining, currently timely treatment or replacement Jane wear lining is the coal means coal fall to ensure the safe use of jane.

　　Coal chute liner is perfect the operation reliability of coal handling system will be greatly improved, while reducing the leakage rate of equipment, improve the site environment, maintenance work will also greatly reduce relatively greatly reduces the cost of production, to ensure the normal operation of the coal handling system, can fundamentally solve the problem due to the reasons for the drop tube fault coal due to a shortage of coal and boiler unit to reduce the abnormal operation of the load.

　　Contrast the front and rear liners of the coal canis

ter:

　　The replacement of high abrasion resistance of coal chute liner, the replacement maintenance mode is flexible and universal (coal chute lining board size made of several specifications can meet the general use), coal has tried 3 professional liner materials are: manganese steel, ceramic liner, ultra high chromium molybdenum nickel cast steel plate.

　　According to the principle of price, it can be super high chromium nickel molybdenum cast steel plate the highest price, so that the use of high chromium nickel molybdenum cast steel plate, and gradually to the transformation of coal chute lining plate, in order to improve the reliability of operation of coal transportation system fundamentally.
