First, the type of belt conveyor and applicable conditions
Belt conveyors are classified into two types: drum drive type and wire rope traction type. Generally, mine mining areas are mostly driven by drums, and those used in large lanes are also drum-driven, but they are also useful for wire rope traction. The main shaft belt transportation is generally carried out by wire rope.
Belt conveyors can be used for both horizontal and inclined transport. The tilt angle is limited when used for tilting transport. Normally, the inclination angle when transporting obliquely upwards does not exceed 18 degrees, and the inclination angle when transporting downwards does not exceed 15 degrees. In order to reduce the serious wear of the conveyor belt, the belt conveyor should not transport the angular goods.
Second, the structure and working principle of the belt conveyor
(1) The composition of the belt conveyor
The components of the belt conveyor are: machine head (including motor, transmission, roller, etc.), fuselage part (including frame, roller), tail, tape, attachments (including tensioning device, cleaning device) , brakes, etc.)
(2) Working principle of belt conveyor
Conveyor belts (or travellers) are connected in a closed loop, tensioned by tensioning devices, driven by the motor, by friction between the conveyor belt (or wire rope) and the drive roller (or drive wheel) The belt (or wire rope) is continuously operated to achieve the purpose of transporting the load from the loading end to the unloading end.
