Problems solved by technology

[0002] At present, the coal used in various boilers, reverberatory furnaces, and drying kilns is mostly directly put into the kiln for combustion. Because the raw coal contains a large number of coal particles, these coal particles cannot be fully burned and are used as raw materials. Converted into smoke and dust and discharged, polluting the environment and causing waste

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.

Description

Technical field: [0001] The invention relates to a coal pulverizing device, in particular to a coal pulverizing machine. Background technique: [0002] At present, the coal used in various boilers, reverberatory furnaces, and drying kilns is mostly directly put into the kiln for combustion. Because the raw coal contains a large number of coal particles, these coal particles cannot be fully burned and are used as raw materials. It is converted into smoke and dust and discharged, polluting the environment and causing waste. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned defects, and provide a simple structure, safe and reliable coal pulverizer. When the machine works, the coal particles are ground into fine powder and sprayed into the kiln for complete combustion, which not only reduces pollution, but also It also saves resources. [0004] The scheme of the present invention is composed of a seat frame, a machine body, a...
