Screw conveyor drive unit enclosed by boxes and spiral groove composed by rotating spiral groove inside the coal output goes. The features are: simple structure, the cross-section of small size, good sealing, reliable, low cost, ease of loading and unloading the middle, conveying the reverse direction, the opposite can also be transported in both directions simultaneously. Delivery process but also on the material stirring, mixing, heating and cooling operations. Adjustable material flow through the loading gate. But not transport perishable, viscous, easy caking and chunks of material. Material easily broken during transport, and spiral chute easy to wear. Larger units of power. Use to maintain the tightness between the trough and trough screw with proper clearance. Perpendicular to the vertical screw conveyor is suitable for short-distance transportation. Flexible screw conveyor screw shaft 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 any thickness can be made with the size, the entire production of non-standard screw pull inappropriate. From the perspective of the screw conveyor conveying the material displacement direction of the division, Hong Tai screw conveyor is divided into horizontal and vertical screw conveyor screw conveyor two types, mainly used for all kinds of powder, granular and small block, etc. horizontal and vertical lift transport loose materials, the screw conveyor suitable for transporting perishable, viscous, easy caking or high temperatures, afraid of pressure, there is a greater corrosive special materials. Generally consists of a conveyor screw conveyor body, expected out and drive three major components; screw conveyor screw spiral blade surface entities, belt three forms spiral blade surface and helical surface, where the spiral blade surface application relatively small, mainly used to transport large viscosity and compressibility of the material, this snail hanging face, at the completion of delivery job, both of materials and finish stirring, mixing, and other functions. Screw conveyor compared with other transportation equipment, with the whole cross-section of small size, good sealing performance, stable and reliable, can be more than the middle-point loading and unloading and safe operation, easy maintenance. Botou City Jie Tai Machinery Factory is located in Hebei Botou Industrial Development Zone, is the design, manufacturing and installation, commissioning and after-sales service in one of the environmentally friendly product development and production base, the company has strong economic and technological strength, high-quality management personnel, CAD design work and sales, finance computer network management, automation with electronic control system. From a fundamentally product development, test, marketing, installation, commissioning, service as one of professional environmental corporate philosophy.
