Coal bunker blocking position in the form of 
 Common coal bunker stick plugging in two forms, one is wet pulverized coal is first bonded warehouse wall, layer by layer, added together, and the last is the formation of a similar rat holes shape, warehouse and then loaded coal will result in blocking positions. Another is within the frictional resistance between the wet pulverized coal, combined it with the outside of the silo wall frictional resistance when the coal bunker full of coal, the bottom conical section of the coal port formed at a similar card housing and rust camber shape (commonly known as the bypass). The gate can only be put down very little caving part of the upper coal due to the camber and blocking positions. 

 Coal bunker blocking positions consequences 
 In order to solve the problem of bonding blocking positions over the years, people would also like to a lot of ways, such as the warehouse wall tiling Shop steel plate, using air guns or hammer blows are potential completely resolved, and manually poke the coal bunker is often resulting in personal injury. 

 Coal bunker liner performance principles 
 A lot of research and experiment, the final decision emerging Limited coal bunker board lined with coal bunker, the use of coal bunker dedicated board self-lubricity and viscosity in order to reduce the friction coefficient, and reach to solve the phenomenon of blocking positions. 

 Coal bunker liner installation method 
 Use the nail to large piece of sheet metal barn walls, thus completely solved the problem of coal bunker bond blocking positions. Generally do not need covered positions, and put as long as the conical segment of the lower part of the coal bunker coal mouth part and part of the silo Shop lining about 1 m to resolve the two forms of rat holes and camber caused by the blocking position. 

 Solve the effect of coal warehouses lining 
 Henan, Shandong, Shanxi, Hebei Province, many coal mines and power plants use the [Emerging Chemical Co., Ltd. production of coal bunker liner] showed that the effective solution to the blocking position, the effective utilization of the coal bunker by 20% - -50% to 100%, to avoid production disruptions caused by the blocking position and poke warehouse accident, reducing the Bunker broken, saving the cost of clearance, greatly reducing the loading time, reducing the pressure wagon phenomenon, reducing workers' labor intensity, social and economic benefits are significant coal bunker lining the reasons for China's coal mines, power plants, terminal storage of coal, coal bunker are basically concrete pouring from its surface Guanghua, friction coefficient, The high water absorption, which is often caused by bonding and blocking positions, the main reason. Blocking positions accident is particularly serious in the case of soft coal mining, coal and water.
