Classification and application of screw conveyors

2012-03-06 09:08:45 Types of screw conveyors application link address: http://www.hnshusongji.com/xwdt140.html There are several types of screw conveyors, which are very versatile. Let’s introduce each Purposes of similar conveyors: tubular belt conveyors are suitable for conveying various bulk materials with a density of 0-2.5t/m3 under various complex terrains. Common tubular tapes are used in the working environment temperature range of -25～+40℃; Widely used in electric power, building materials, chemical, mining, metallurgy, wharf, port, coal, food and other industries material conveying system. Coal mine belt conveyors are widely used in metallurgy, coal, transportation, hydropower, and chemical industries due to the advantages of large transportation capacity, simple structure, convenient maintenance, low cost, and strong versatility. The belt conveyor has the advantages of large conveying capacity, simple structure, convenient maintenance, low cost, and strong versatility. The belt conveyor can convey various bulk, granular and other bulk shapes with a bulk density of 0.5 to 2.5 tons/m3. Materials or packaged products. Tubular screw loading conveyor is a continuous conveying device that uses spiral rotation to move materials. It is suitable for conveying flour, cereals, cement, fertilizer, ash, sand, stones, coal powder, small coal and other materials. It is not suitable for conveying materials that are perishable, too viscous, and easy to agglomerate; it can be arranged in a horizontal or inclined conveying mode. The standard diameter series of the vertical screw conveyor screw. The material that requires a stable flow must be added from the bottom of the screw. When the feed is interrupted, the unloading at the top of the screw conveyor is also interrupted immediately. The screw itself will not be emptied unless it is intentionally cleaned. Out of materials. Otherwise, no matter it is running or stopped, there will always be materials in the spiral groove. The structure is simple, the space occupied is small; the power consumption is small; it is easy to seal the transportation: the manufacturing cost is correspondingly low, the disadvantage is: the transportation volume is small, the transportation height is small; it is suitable for transportation of various powdery and granular materials, such as flour, cement , Sand and other reclaimed rubber powder, etc. Vertical screw conveyors are not suitable for conveying materials that are perishable, viscous, agglomerated and corrosive. The working environment should be within the range of -20~50℃, and the temperature of conveying materials should be lower than 200℃. Compared with the traditional shafted screw loading conveyor, the shaftless screw conveyor has a certain degree of flexibility for the integral steel screw to push materials. Features: strong anti-winding: no central axis interference, special advantages for conveying belt-like and easy-winding materials; fully enclosed conveying and easy-to-clean spiral surface can ensure environmental sanitation and the delivered materials are not polluted or not Leakage; Because the screw has no shaft, the material is not easy to be blocked, and the discharge port is not blocked, so it can run at a lower speed, smooth transmission and reduce energy consumption; the conveying capacity is 1.5 times that of the traditional shafted screw conveyor with the same diameter; the single conveying length can reach 60 meters. And according to the needs of users, it can adopt multi-stage series installation to transport materials over long distances. The material can be discharged from the bottom and at the end. The special liner is used to work under high temperature.
