Working principle of scraper conveyor
The working principle of a scraper conveyor is to use an open chute as a support for coal, gangue, or materials, and fix the scraper on a chain (forming a scraper chain) as a traction component. After the transmission part of the machine head is started, the sprocket on the drive head shaft rotates, causing the scraper chain to circulate and move the animal material along the chute until it is unloaded at the machine head. The scraper chain runs continuously in a closed loop around the chain rotation to complete the transportation of materials.
Environmental conditions for the use of scraper conveyor
● The ambient temperature is between -10 ° C and+40 ° C.

● Places without long-term continuous dripping.
According to the form of scraper chains, they can be divided into four forms: medium single, medium double, edge double, and quasi edge double chains;
According to the conveying capacity and motor power, it can be divided into: light (single motor P<75kw), medium (single motor 75 ≤ p ≤ 160kw), heavy (single motor 200 ≤ p ≤ 400kw), and ultra heavy (single motor p>400KW);
