LS screw conveyor

Product Description

LS screw conveyor is a mechanism that uses rotating helical blades (usually in pipes) to move liquid or granular materials. The diameter of the screw is 100mm-1250mm, and there are twelve specifications in total. The maximum length of the driving screw machine can reach 40m (extra-large 30m), and the double-drive screw machine adopts the middle disconnected shaft structure, and the maximum length can reach 80m (extra-large 60m). The delivery volume per hour is 1.2-458m³/h.

The LS screw conveyor is improved from the GX screw conveyor. The main improvement is the suspension bearing structure, which allows materials to pass through more smoothly. It is widely used in mining, chemical, feed, grain and oil, cement plants, commercial concrete and construction industries to transport various A variety of powdery, granular, small block materials and other loose materials, fast speed, no material jams, no arching, smooth discharge.

Types of LS Screw Conveyor

1. Different materials

Carbon steel screw conveyor: mainly used in cement, coal, stones and other industries with high wear and no special requirements for sanitation.

Stainless steel screw conveyor: It is mainly used in food, grain, chemical and other industries that have requirements on the conveying environment. It has a high degree of cleanliness and will not pollute materials.

2. According to the structure:

Shaftless screw conveyor: granular/powder materials, wet/paste materials, semi-fluid/viscous materials, easily entangled/easy to block materials, materials with special hygienic requirements.

Shafted screw conveyor: materials that are not easy to stick, and have certain friction. There are certain requirements for the wear resistance of the screw conveyor.

Working Priciple of LS Screw Conveyor

LS screw conveyor is composed of motor, reducer, screw shaft, screw blade and other parts. The screw blade has a large wheelbase, which is not easy to cause blockage when conveying powdery materials. At the same time, the screw blade realizes the material flow by continuously pushing the material. Migration, and can complete the conveying function of materials.

Features

Stable transportation: suitable for small-scale transportation, stable transportation, and can play a good role when the transportation site is limited. The LS screw conveyor can transport 134m of material per hour. The LS screw conveyor has a single-shaft drive screw and a double-shaft drive screw.

Multi-point loading and unloading: It can be loaded and unloaded at any point on its conveying line, and the middle loading and unloading is convenient. Compared with other screw conveyors that cannot load and unload materials at any time, it has obvious advantages and can meet the needs of customers.

Good sealing performance: the head and tail bearings are installed outside the casing, and sliding bearings are used in the middle, and the dust-proof sealing device is designed to avoid dust when the material is conveyed, and will not pollute the environment too much, which is beneficial to the later sanitation cleaning.

Long service life: the suspension shaft and the screw shaft are connected by a slider. When removing the screw, there is no need to move the drive device, and when removing the suspension bearing, there is no need to move the screw. The suspension bearing can be lubricated without removing the cover plate, which saves the replacement time of equipment accessories and is reliable. High durability and long service life.
