The Introduction of Grain scraper chain conveyor

► Introduction
Grain scraper chain conveyor is a light type buried scraper conveyor. It is widely used to convey grain such as soybean, wheat, rice, flour etc. Compared to the ordinary type, the casing thickness of QMS type is smaller, thus lose the whole weight and save money.

► Working principle
When conveying in horizontal direction, under the constraints of material weight and casing sidewall, producing internal friction between the materials. The material can be conveyed forward along to the scraper chain, form a continuous whole material flow. When conveying in vertical direction, because of the constraints of material arch camber, weight and casing sidewall, producing internal friction that prevent the material falling down. The material can be conveyed upward along to the scraper chain.

►Features

1,Grain buried scraper conveyor is completely enclosed for clean plant operation
2.Large capacities for conveying in a compact space
3.Higher conveying speed
4. Can reach multipoint charging and discharging
5.Variety of side & bottom abrasive resistant steel liners
6.Liner fasteners that are positioned clear of material flow.

►Applications
It is widely used to convey grain such as soybean, wheat, rice, flour etc.

►Selection condition

    1. Material need to be processed_____?
    2. Feeding size____mm, bulk density____t/m3, material temperature_____degree ?
    3. Processing capacity____t/h ?
    4. Conveying length(distance between inlet and outlet)_____m?
    5. Inclination angle of conveyor______degree?

The Introduction of Incline scraper chain conveyor



► Brief Introduction:
Incline scraper chain conveyor is bulk material conveying equipment, which consists of head section with driving device, connect section, tail section, tension device, as well as scraper and chains.By means of moving chains, it can continuously transport the materials in closed rectangular casing vertically or at a large incline. 
The MC buried scraper conveyor is widely used in cement plant, coal, metallurgy, mining, light, construction, chemical, grain, power industries etc.

►Operating Principle:
When scraper chain conveyor machine transports material aslant, the internal friction caused by three parts:the pressure which comes from chains in conveying direction to the materials, the action which comes from the materials themselves and the gravity of the material. This friction ensures the stable situation between material layers, and it can overcome external frictional resistance which caused by moving materials in the trough and make materials transport as a a whole fluid. 

►Main Features:
1.Totally enclosed structure, light weight, small volume. 
2.Convenient installation and maintenance. 
3.Vertical or large inclined transport from 30° to 90°. 
4.Multiple material feeding point and discharging point. 
5.Conveying distance is up to 40m with material temperature lower than 120℃. 
6.Widely used in cement plant, coal, metallurgy, mining, light, construction, chemical, grain, power industries etc.
