Vertical screw conveyors are not suitable for conveying materials that are prone to undergo significant chemical reactions, have high viscosity, and are prone to sticking to the blades due to limited material circulation in the machine slot.

The vertical screw conveyor is suitable for conveying dry materials with a bulk density of ≤ 1.3t/m ³, such as grains, bran, feed, chemical raw materials, cement, etc., in powder, granular, and non viscous forms, vertically or at a large inclination angle. The material temperature generally cannot exceed 80 ℃, and vertical screw conveyors are not suitable for conveying viscous materials in block machines. Spiral conveyors have the advantages of simple structure, low manufacturing cost, strong sealing, and easy operation.

The vertical screw conveyor adopts an upper drive device, and the motor is installed at the head of the main machine. The power is transmitted to the main shaft through a belt, thereby driving the screw to operate. The 200 and 250 models are equipped with single drive forms, while the 315 model is equipped with both single drive and dual drive forms.

The vertical screw conveyor can calculate the conveying capacity of the screw conveyor based on the diameter of the screw conveyor and the number of screw revolutions. The height of the vertical screw conveyor refers to the distance between the feeding port and the discharging port, ranging from 2.5 meters to 15 meters, with a range of 0.5 meters. Users can choose according to their needs.

Vertical screw conveyor is a continuous conveying equipment that uses forced feeding screw rotation to transport and lift materials. Vertical screw conveyor is suitable for powder, block, and granular materials such as flour, grains, cement, fertilizers, ash, sand, stones, coal powder, block coal, etc. The material temperature generally does not exceed 80 ° C. It is suitable for industries such as building materials, metallurgy, chemical industry, mining, machinery manufacturing, coal ash, tobacco, grain, food, and medicine.
