A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, and many others.
 They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaft-less spiral", driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process.
Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases.
Features for the model
(1) Installation, disassembly and maintenance is very convenient, and low failure rate
(2) Simple structure, small size, so the occupied area and space is not very big
(3) Can have multiple feeding port and discharging port as needed
(4) Easy to form the production line, can be connected with packaging equipment, storage equipment, mixing equipment or screening equipment
(5) Can be customized with hopper or running wheels and others                                    (6) Reliable sealing

Plastic Injection Clear Housing
The transparency of the plastic injection transparent shell matrix resin itself has a great influence on the transparency of PP plastic products. In order to improve PP transparency, a small amount of polyacrylate resin with good transparency and compatibility can be added.
(1) the inorganic nucleating agent mainly consists of ultra-fine talc powder and SiO2, and also includes calcium carbonate, mica powder, inorganic pigments and fillers, etc., which is cheap in price and rich in source, but has certain influence on the gloss and transparency of the products.
(2) organic nucleating agent organic nucleating agent is a kind of organics with low relative molecular weight, represented by sorbitol and its derivatives. It has good compatibility with matrix resin and can significantly improve product transparency and surface gloss.
(3) in the case of sorbitol, when the amount of nucleating agent exceeds 0.3%, the effect of transparency improvement is not obvious, and even decreases. However, when the dosage is less than 0.2%, the nucleation quantity is insufficient and the transparency is not increased enough. It can be seen that the amount of nucleating agent should be between 0.2-0.3%. Therefore, suitable nucleating agent content can better improve the transparency of PP.
