U-shaped screw conveyor

The U-shaped screw conveyor models include U200, U250, U300, U400, U500, U600, etc. The hourly conveying capacity can reach 143 cubic meters, and the conveying length does not exceed 20 meters.

The U-shaped screw conveyor, abbreviated as LS screw conveyor, is commonly known as a horizontal screw conveyor. The shell adopts a U-shaped outer wall, which looks like a U-shaped groove, so it is named U-shaped screw conveyor. The overall design and construction of the machine are relatively simple, consisting of U-shaped grooves, feeding ports, flanges, drive devices, lining plates, upper covers, and other components. The U-shaped conveyor has a small cross-sectional area, strong sealing of the body, simple operation of the equipment, no hidden dangers for operators, low manufacturing cost, and high energy consumption.

The housing shape of the U-shaped screw conveyor is U-shaped, with a U-shaped groove cover on the upper part of the housing, hence the name U-shaped screw conveyor. According to the design form, it can be divided into two types: closed and open.

The main applications of U-shaped screw conveyor are transportation, mixing, dehydration and drying, unloading and other operations. The common U-shaped specifications and models are: 200250300400500, and the length of a regular U-shaped conveyor ranges from 4 meters to 50 meters. Of course, non-standard U-shaped screw conveyors can also be designed according to operational requirements.

There are various conveying methods for U-shaped screw conveyors, including horizontal conveying, inclined conveying, vertical conveying, and even combinations of several forms. The intermediate suspension bearing of the conveyor adopts two interchangeable structures of rolling and sliding. This U-shaped screw conveyor can work in conjunction with other conveying equipment. And it can be used in conjunction with other conveying equipment or working devices.

The U-shaped screw conveyor usually consists of three parts: the screw machine body, the inlet and outlet device, and the driving device. Our company does not provide electrical switches and motor starting equipment.

The U-shaped screw machine body consists of three types: the head section, the middle section, and the tail section. In general, during the final assembly of the factory, the middle sections are arranged in order of length. The longer middle section is close to the head section, while the middle sections of the same length are adjacent to each other. If there are special requirements, the arrangement order should be given when ordering. Spiral conveyors are driven by motor reducers. There are three types of driving devices: ZQ series reducer+Y series motor, YTC gear reducer motor or cycloidal pinwheel reducer.

The feeding and discharging devices of U-shaped screw conveyor have four types: feeding port, square discharging port, manual pushing discharging port, and rack type discharging port. The user opens and welds on the machine at the usage site. When arranging the position of the inlet and outlet, attention should be paid to protecting the distance from the outlet to the end, and avoiding collision between the outlet and the oil cup of the suspension bearing, the flange of the casing connection, the base, etc. The inlet and outlet ports can also be made into circular flanges according to user needs.

The U-shaped screw conveyor is suitable for small-scale operations, with stable conveying, and can play a good role in situations where the conveying site is limited. Strong sealing has great advantages for situations with high dust and environmental requirements, which can avoid the generation of dust during transportation. However, U-shaped screw conveyors are not suitable for long-distance transportation with large angles of inclination, and their cost is relatively low compared to pipe conveyors. Therefore, it is recommended to choose U-shaped screw conveyors as much as possible when transporting horizontally

U-shaped screw conveyor is a widely used conveying equipment. It is mainly used to transport powdered, granular, and small block materials, such as coal powder, soda ash, production rubber powder, zinc oxide, calcium carbonate, and small block coal. It is not suitable for conveying materials that are prone to deterioration, high viscosity, and easy agglomeration. It is suitable for horizontal or inclined conveying of powdered, granular, and small block materials. The material temperature is less than 200 ℃. The conveying equipment is widely used in various industries, such as building materials, chemical industry, power, metallurgy, coal mine charcoal, grain, etc. The U-shaped screw conveyor can also perform operations such as mixing, blending, heating, and cooling of materials during transportation, and the material flow rate can be adjusted through loading and unloading gates.
