Screw conveyor features: 1, spirochetes small diameter, high speed, high throughput, accuracy, good transport conditions; 2, the drive uses a gear reducer with torque, low noise, no oil leakage, long life ; 3, the conveyor housing made of high quality seamless pipe, flange connection, the overall steel is good, carrying capacity, at the time of delivery, whether the level of transmission, or large angle can be continuously fed, and are free to choose the work location and work attitude disassembly easy to move; 4, good sealing performance machine, no dust leakage, safe and reliable, is the best new generation of environmentally friendly products. Screw conveyor classification and application: screw conveyors transport the material from the perspective of the direction of displacement divided into horizontal screw conveyor screw conveyor and two types of vertical screw conveyor, screw conveyor is mainly used for all kinds of powder , granular and small block level and other loose materials transport and vertical lift, 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 other material temperature less than 200 ℃. Screw machine suitable for transporting perishable, viscous, easy caking materials. In concrete mixing station, the role of the screw conveyor has been the greatest expression. Technical characteristics of screw conveyor: Screw mainly by the drive slot closed box and helices by rotating spiral groove inside the coal output goes. 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 Advantages: screw conveyors and other transportation equipment, compared with the whole cross-section of small size, good sealing performance, stable and reliable, low cost, ease of loading and unloading the middle, conveying the reverse direction, but also at the same time conveying in the opposite two directions. 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.
