Screw machine is widely used in various industries, such as building materials, chemical industry, electric power, metallurgy, coal coke, grain and so on. Suitable for horizontal or inclined transportation of powdery, granular and small block materials, such as coal mine, ash, slag, cement, grain and so on. The material temperature is less than 200℃. Screw machine is not suitable for conveying perishable, sticky and caking materials. In the concrete mixing station, the role of screw conveyor has been the greatest embodiment.
Product features:
Simple structure, small section size, good sealing performance, reliable operation, low manufacturing cost, convenient intermediate loading and unloading, and the conveying direction can be reversed or conveyed in two opposite directions at the same time. During transportation, materials can also be stirred, mixed, heated and cooled. The material flow can be adjusted by loading and unloading the gate. However, it is not suitable for transporting perishable, sticky, caking and bulky materials.
During transportation, materials are easily broken, and screws and chutes are easily worn. High unit power. When in use, the groove should be kept sealed, and there should be a proper gap between the screw and the groove.
The vertical screw conveyor is suitable for short-distance vertical transportation.
The screw of flexible screw conveyor is composed of flexible shaft and synthetic rubber blade, which is easy to bend and can be arranged at will according to the site or process requirements for space transportation. There are two types of blades of screw conveyor: pull-in type and pull-out type. Pull-in type can be made into any thickness and size, and pull-in type is not suitable for making non-standard screws.
From the displacement direction of conveying materials, screw conveyors can be divided into horizontal screw conveyors and vertical screw conveyors, which are mainly used for horizontal conveying and vertical lifting of loose materials such as powder, granules and small blocks. This kind of screw conveyor is not suitable for conveying special materials that are easy to deteriorate, sticky, caking or high temperature, afraid of pressure and corrosive.
There are two forms of spiral surface of screw conveyor: solid spiral (S method) and belt spiral (D method). The screw shafts are connected by flanges, which ensures the interchangeability of the connecting shafts and is convenient for maintenance.
The cover of the screw conveyor is tile-shaped and clamped on the shell through the cover buckle. If the sealing performance needs to be improved, users can add waterproof canvas between the cover and the shell by themselves.
There are four types of feeding and discharging devices of screw conveyor: feed inlet, square discharge outlet, hand-push discharge outlet and rack discharge outlet, which are welded to the machine body by users at the use site. When arranging the positions of the inlet and outlet of the screw conveyor, attention should be paid to ensuring the distance from the inlet to the end, and avoiding the collision between the inlet and the oil cup of the suspension bearing, the connecting flange and the base of the casing.
