Enclosed Design Fly ash Horizontal Scraper Chain Conveyor has the advantages of simple structure, light weight, small size, good sealing and convenient installation and maintenance. It can not only horizontal transport but also inclined and vertical transport;
Not only can single conveyor, but also can be combined layout, series conveyor; Can be multi-point feeding, can also be multi-point unloading, process layout is more flexible. Due to the closed shell, the working conditions can be significantly improved when conveying materials to prevent environmental pollution.
Enclosed Design Fly ash Horizontal Scraper Chain Conveyor is a transportation equipment for conveying bulk materials according to a predetermined target by means of a scraper chain moving in a closed shell. It has the advantages of small volume, strong sealing, good rigidity, flexible process layout, convenient installation and maintenance, and can be multi-point feeding and multi-point unloading. Therefore, the working conditions of workers are significantly improved and environmental pollution is prevented. The principle of the buried scraper conveyor is dependent on the internal friction of the material and the side pressure of the shell to the material. In the process of conveying the material, the pressure of the scraper chain in the direction of movement and the pushing force of the material on the upper material under the continuous feeding. The synthesis of these forces is enough to overcome the external friction resistance generated between the material and the shell in the groove and the weight of the material itself. So that the material can form a continuous material flow forward movement when horizontal, inclined and vertical

Selection of buried scraper conveyor machine bearings
The bearing on the small sprocket shaft of buried chain conveyor machine is a pair of GB/T276-6112 deep groove ball bearings.
Large sprocket shaft bearings of buried chain conveyor machine use two pairs of GB/T276-6308 deep groove ball bearings and a pair of GB301-8208 thrust ball bearings.
Deep groove ball bearings have a simple structure. It is mainly subject to radial loads, also could withstand a certain amount of two-way axial load. It can replace thrust bearings at high-speed devices. The friction coefficient is small, the speed limit is high, and the price is low, and it has the widest range of applications.
Thrust ball bearings can only be subject to one-way axial load. When turning, the steel ball rubbed with the cage and become heat due to centrifugal force, so the limit speed is low. And the ferrules can be separated.
The choice of bearing for embedded scraper conveyor can be selected according to the diameter of the shaft.
