Abstract
The centrifugal compound grind coal powder machine has a main shaft at the base of the body, three sets of flying hammer of various diameters from the center of the shaft, linking as an integral with the vane by the bolt fastened tightly on the flange plate of the main shaft. Fan cabin set at the front of the machine, with wind introduction fan inside the fan cabin, with powder outlet at the left, and powder spraying barrel at the outlet. Rear of the machine sets spiral feeder whose left installs a worm decelerator, top of the feeder having the feeding hopper. It can be used together with the regeneration energy saving smelting-furnace, spraying coal powder into the furnace, reducing burning cost to over 66%. It is reduced in energy consumption, alleviated in contamination and increased in effect. It will be an ideal new generation product.
