Advantages of belt conveyors

Speeding up the innovative development of belt conveyors, especially belt conveyors with electric rollers as driving devices, is of great significance. Because it has the characteristics of compact structure, high transmission efficiency, low noise, long service life, stable operation, good working reliability and tightness, small space, etc.

Advantage

Reliable operation. Belt conveyors are used in many important production units that require continuous operation, such as coal transportation in power plants, bulk materials in steel and cement plants, and ship loading and unloading in ports. If the machine is stopped on these occasions, the losses are huge. When necessary, the mobile belt conveyor can work continuously from shift to shift.

Low power consumption of belt conveyor. Because the material and the conveyor belt have almost no relative movement, not only makes the running resistance small (about 1 / 3-1 / 5 of the scraper conveyor), but also the wear and tear on the cargo load are small, and the productivity is high. These are conducive to reducing production costs.

The conveyor line of the belt conveyor is highly adaptable and flexible. The length of the line is determined according to the needs. It is a few meters short and the length can reach more than 10km. It can be installed in small tunnels, or it can be erected over the ground with chaotic and dangerous areas.

According to the requirements of the process flow, the belt conveyor can be very flexible to receive material from one or more points. It can also discharge to multiple points or several sections. When feeding material to the flame retardant conveyor belt at several points at the same time (such as the conveyor under the coal bin of the coal preparation plant) or feeding the conveyor belt through the uniform feeding equipment at any point along the length of the belt conveyor, the belt conveyor The machine becomes a main transportation trunk line.

The belt conveyor can pick up material in the roadway under the storage yard of the coal storage yard. When necessary, it can also mix different materials in each pile. The material can be simply unloaded from the head of the inclined belt conveyor, or it can be unloaded at any point along the length of the conveyor belt by a plow unloader or a mobile unloader.

The screw conveyor is commonly called auger, which is suitable for the horizontal conveying, inclined conveying and vertical conveying of granular or powdery materials. The conveying distance varies according to the deformity, generally from 2 meters to 70 meters.

Conveying principle: The rotating spiral blades move the material to be conveyed by the screw conveyor. The force that prevents the material from rotating with the screw blades of the screw is the material's own weight and the frictional resistance of the screw conveyor casing to the material.

Belt Conveyor

Structural features: spiral blades are welded on the rotary shaft of the screw conveyor, and the blade surface types include solid surface type, belt surface type, blade surface type, etc. according to the different materials being conveyed. The screw shaft of the screw conveyor has a thrust bearing at the end of the material moving direction to give the screw axial reaction force with the material. When the machine length is long, an intermediate hanging bearing should be added.

The rotation direction of the rotation axis of the screw conveyor determines the conveying direction of the material, but generally, when designing the screw conveyor, the rotating blades are designed according to the single conveyance. When conveyed in the reverse direction, the service life of the conveyor will be greatly reduced.
