Description

Technical Field

[0001] The utility model relates to the technical field of blue coke production, in particular to a raw material crushing device for blue coke production. Background Art

[0002] Semi-coke, also known as semi-coke or coke powder, is made by burning high-quality Jurassic coal blocks that are abundant in the Shenfu coalfield. As a new type of carbon material, semi-coke has gradually replaced metallurgical coke with its high fixed carbon, high specific resistivity, high chemical activity, low ash content, low aluminum, low sulfur, and low phosphorus. It is widely used in the production of calcium carbide, ferroalloys, ferrosilicon, silicon carbide and other products, becoming an irreplaceable carbon material. In addition to coal blocks, semi-coke can also be made of plants such as bark, pine needles, cypress or fruit shells. In the production of semi-coke, the raw materials need to be crushed to improve production and processing efficiency.

[0003] The existing raw material crushing device for lignite production directly crushes the raw materials after placing them into a crushing box. The crushed lignite is of different sizes and then mixed and discharged into a collection box. Due to different market environment requirements, the demand for lignite particle size is also different, resulting in the mixed collected lignite cannot be effectively distinguished, making it more troublesome to sell after production. In addition, due to the diverse lignite particle sizes required by the market environment, a variety of filter plates with different sized filter holes are required for the crushing and screening of raw materials during the production and processing of lignite. However, the filter plates used in the existing raw material crushing device for lignite production are not convenient to replace, resulting in a relatively single size type of screened lignite.
