Screw machine is widely used in various industries, such as building materials, chemicals, power, metallurgy, coal carbon, food and other industries, for horizontal or inclined conveying powder, granular and small bulk materials such as coal, ash, slag, cement, food and so on, the material temperature is less than 200 ℃. Screw machine suitable for transporting perishable viscous, easy caking materials. Concrete mixing station, the role of the screw conveyor has been the greatest expression.

Technical characteristics of the screw conveyor is driven by means closing the slot box and helices by rotating the spiral groove inside the passage of coal output.

Screw conveyor features are: simple structure, a cross section of small size, good sealing, reliable, low cost, easy to intermediate loading and unloading, conveying the reverse direction, the opposite can also be conveyed simultaneously in both directions. Delivery process but also the material for stirring, mixing, heating and cooling operations. Adjustable material flow through the loading gate. But not transport perishable viscous, easy caking and large pieces of material. Easily broken during transportation of materials, the spiral trough and easy to wear. Larger units of power. Use to maintain the seal between the trough and spiral trough with proper clearance.

Vertical screw conveyor suitable for short-distance vertical transportation. Flexible screw conveyor screw axis and a flexible blade composed of synthetic rubber, easy to bend, can be arbitrarily arranged according to the site or process requirements, space transportation. Screw conveyor blades have now pull and pull the entire loss, now pull can be made of any thickness and size, should pull the whole production of non-standard screw.(hot selling concrete batching plant)

From the perspective of the direction of displacement of the delivery of materials division, the screw conveyor is divided into horizontal and vertical screw conveyor screw conveyor are two types, mainly used for various levels of powder, granular and small block and other loose materials transport and vertical lift, the screw conveyor suitable for transporting perishable viscous, easy caking or high temperatures, afraid of pressure, there is a greater corrosive special material.

Usually by the conveyor screw conveyor body material inlet and outlet and the drive unit has three major components; helical screw conveyor spiral blade surface entities with screw-type three forms of surface and spiral blade surface, wherein the spiral blade surface application relatively small, mainly used to transport large compressibility and the viscosity of the material, this snail hanging face, in complete delivery job, both of materials and the completion of the stirring, mixing, and other functions.(ready-mixed concrete batching plant)

Concrete UNITA world believe screw conveyor compared with other transportation equipment, the whole cross-section having a small size, good sealing performance, stable and reliable operation, the intermediate multi-point loading and unloading and safe operation, easy maintenance and other advantages.
