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.

● In an environment without damaging insulation with gas or steam.

● An environment with explosive gases such as methane and air mixtures, coal dust, etc.

● The altitude is below 2000 meters.

● 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);

According to the application location, it can be divided into: coal mine underground conveyors, coal mine above ground conveyors, and non coal mine mountain conveyors;

According to the unloading form, it can be divided into end unloading and side unloading;

According to the structure of the central groove, it can be divided into open bottom type and closed bottom type;

According to the form of the driving motor, it can be divided into single speed motor driving type and dual speed motor driving type.

Scraper conveyor installed power: 5.5kw-320kw, slot width: 280mm-764mm, conveying capacity: 30-700t/h.
