A detailed explanation of LSY type screw conveyor at concrete mixing plant
The main function of the LSY screw conveyor in the concrete mixing plant is to transfer cement, fly ash and other powdery materials from cement silo (bin). It is the important powder conveying equipment in the concrete mixing plant. The following is an introduction to the technical characteristics of the screw conveyor. It is hoped that it will help you to understand the powder conveying equipment in the concrete mixing plant equipment!
The screw conveyor is generally composed of three parts: a conveyor body, an inlet and outlet, and a driving device; the screw blades of the screw conveyor have three types: a solid spiral surface, a belt spiral surface, and a blade spiral surface. Among them, the use of blade spiral surface is relatively few, it mainly used for conveying more viscous and compressible materials. This screw-suspension type has the functions of mixing the materials as well as completing the conveying operation.
The characteristics of the screw conveyor are: simple structure, small cross-sectional size, good sealing, reliable work, low manufacturing cost, convenient loading and unloading in the middle, and the conveying direction can be reversed, and can also be conveyed in the opposite direction at the same time. The material can also be agitated, mixed, heated, and cooled during transportation. The material flow can be adjusted by loading and unloading gates. However, it is not suitable to transport perishable, viscous, agglomerate and bulk materials. In the process of conveying, the material is easily broken, and the spiral and feed trough are easy to wear. The unit power is large. Keep the tightness of the feed trough and the proper clearance between the screw and feed trough during use.
Vertical screw conveyors are suitable for short vertical transport. The spiral of the flexible screw conveyor is composed of a flexible shaft and a synthetic rubber blade, which is easy to bend and can be freely arranged according to site or process requirements for space transportation. Spiral conveyor blades are now pull-type and pull-out, now pull-type can be made of any thickness and size specifications, the entire pull-style should not be made of non-standard spiral.
From the perspective of the direction of displacement of the transport material, Jianxin screw conveyors are divided into two types: horizontal screw conveyors and vertical screw conveyors. They are mainly used for horizontal conveying and vertical lifting of loose materials such as powder, granules and small pieces., Screw conveyor is not suitable for conveying special materials that are easily deteriorating, sticky, easy to agglomerate or have high temperature, pressure, and corrosivity.
Compared with other conveying equipment, the screw conveyor has the advantages of small size of the cross section, good sealing performance, stable and reliable operation, multi-point loading and unloading, safe operation, and easy maintenance.
