Coal mining scraper conveyor is suitable for coal mining face with coal seam inclination angle not exceeding 25 degrees. When coal seam inclination angle is large, anti-skid measures shall be adopted. At present, the fully mechanized mining face mostly uses flexible scraper conveyors to meet the needs of mechanized and comprehensive mechanized coal mining, and is used in conjunction with corresponding coal mining machines, crushers and hydraulic supports.
The electric power of the scraper conveyor is from 7.5KW-1000KW, and the conveying capacity is from 30t / h-3000t / h.There are several common classification methods:
(1) According to the number and arrangement of traction, it can be divided into single-medium chain, side double-chain, medium double-chain and triple-chain scraper conveyor.
(2) According to the arrangement of the chute, it can be divided into overlapping and side-by-side chute conveyors.
(3) According to the structure of the chute, it can be divided into open bottom and closed bottom chute scraper conveyors.
(4) According to loading and unloading methods, it can be divided into end-loading and side-loading scraper conveyors.
(5) According to the power, it can be divided into light (single motor rated power less than or equal to 40KW), medium (more than 40KW, less than 90KW) and heavy (more than 90KW) scraper conveyor.
