Common classification and use of bulk material conveying equipment in Yichang

Bulk conveying equipment is inevitably used in our daily production. Today, Yichang bulk conveying equipment manufacturer will tell you about the classification and use of bulk conveying equipment.

The belt conveyor is composed of the middle frame of the belt and the idler of the driving device tensioning device. The belt is used as the traction and bearing component to continuously transport the bulk materials or finished products

Belt conveyor is a kind of machinery driven by friction to transport materials in a continuous way. It can be used to transport materials on a certain conveying line, from the beginning of the feeding point to the end of the unloading point to form a material conveying process. It can not only transport broken materials, but also transport pieces of goods. In addition to pure material conveying, it can also match the requirements of the process in the production process of various industrial enterprises, The belt conveyor is widely used in various modern industrial enterprises

Universal belt conveyor is composed of conveyor belt, idler, roller and drive, braking, tensioning, diversion, loading, unloading, cleaning and other devices

① Conveyor belt

There are two kinds of rubber belt and plastic belt in common use The rubber belt is applicable to the working environment temperature between - 15 and 40 ° C. The material temperature is not more than 50 ° C. The inclination angle of upward conveying of bulk materials is 12 ° to 24 °. For large inclination conveying, the patterned rubber belt can be used. The plastic belt has the advantages of oil resistance, acid resistance, alkali resistance, etc., but poor adaptability to climate, easy to slip and aging. Bandwidth is the main technical parameter of belt conveyor

② Idler

It is divided into single roller (the wrap angle of the belt to the roller is 210 °~230 °), double roller (the wrap angle is 350 °) and multiple rollers (for high power). There are grooved idlers, flat idlers, centering idlers, and buffer idlers. The grooved idlers (composed of 2~5 rollers) support the bearing branches to transport bulk materials. The centering idlers are used to adjust the transverse position of the belt to avoid deviation. The buffer idlers are installed at the receiving position to reduce the impact of materials on the belt

Technical advantages of belt conveyor

First of all, the belt conveyor operates reliably. In many important production units that need continuous operation, such as coal conveying in power plants, bulk material conveying in steel and cement plants, and ship loading and unloading in ports, the belt conveyor is used. If it is stopped in these occasions, the loss is huge. If necessary, the belt conveyor can work continuously one shift after another

The power consumption of belt conveyor is low. Because there is almost no relative movement between the material and the conveyor belt, not only the running resistance is small (about 1/3-1/5 of the scraper conveyor), but also the abrasion and breakage of the cargo load are small, and the productivity is high. All these are conducive to reducing production costs

The transmission line of the belt conveyor is flexible and adaptable. The length of the line depends on the needs. It can be as short as a few meters and as long as more than 10km. It can be installed in a small tunnel, or it can be erected above the ground traffic chaos and dangerous areas

According to the requirements of the process flow, the belt conveyor can receive materials from one or more points flexibly. It can also discharge materials to many or several sections. When feeding materials to the conveyor belt at several points at the same time (such as the conveyor under the coal bunker of the coal preparation plant) or conveying materials to the belt conveyor through the uniform feeding equipment at any point along the length of the belt conveyor, the belt conveyor becomes a main conveying trunk line

The belt conveyor can take materials from the roadway under the coal storage yard, and can mix different materials in different piles when necessary. The materials can be simply discharged from the conveyor head, and can also be discharged at any point along the length of the conveyor belt through the plough unloader or the mobile unloader

Screw conveyor, commonly known as auger, is suitable for horizontal conveying, inclined conveying, vertical conveying and other forms of granular or powdered materials. The conveying distance varies according to the deformity, generally from 2 meters to 70 meters

Conveying principle: the rotating spiral blade will push the material to the screw conveyor for conveying. The force that makes the material not rotate with the spiral conveyor blade is the weight of the material and the friction resistance of the spiral conveyor shell to the material

Structural features: spiral blades are welded on the rotating shaft of the screw conveyor. The surface type of the blades includes solid surface type, belt surface type, blade surface type and other types according to the different conveying materials. The screw shaft of the screw conveyor has thrust bearing at the end of the material movement direction to provide axial reaction to the screw with the material. When the length of the machine is long, the middle hanging bearing should be added

Double screw conveyor is a screw conveyor with two rotating shafts welded with rotating blades. To put it plainly, the two screw conveyors are organically combined to form a screw conveyor

The rotation direction of the rotating shaft of the screw conveyor determines the conveying direction of the material, but generally the screw conveyor is designed according to the single conveying. When the reverse conveying is used, the service life of the conveyor will be greatly reduced
