Screw conveyor is a kind of machinery that uses a motor to drive spiral rotation and push materials to achieve the purpose of conveying. It can be transported horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation.
II. Working principle and Applictaion
When the material enters the fixed tank, due to the gravity of the material and the friction between the material and the tank, the material accumulated in the lower part of the tank continuously rotates with the spiral body, and moves forward under the push of the rotating spiral blade.
Screw conveyors are suitable for various industries, such as building materials, chemical industry, electric power, metallurgy, coal, food and other industries, and are suitable for horizontal or inclined conveying powder, granular and small lump materials, such as coal, ash, slag, cement, grain, etc. , The material temperature is less than 200℃. The screw machine is not suitable for conveying materials that are perishable, viscous, and easily agglomerated.
1. Large carrying capacity, safety and reliability.
2. Strong adaptability, convenient installation and maintenance, and long life.
3. The whole machine is small in size and high in speed, ensuring fast and uniform delivery.
4. The discharge end is equipped with a cleaning device, the whole machine has low noise, strong adaptability, and flexible layout of the inlet and outlet positions.
5. Good airtightness, the shell is made of seamless steel pipes, and the ends are connected by flanges to form a whole, with good rigidity.

VI.Equipment installation requirements
a. The on-site installation of the inlet and outlet should make the
flange support surface of the inlet and outlet parallel to the axis
of the screw machine; the flanges connected to it should be tightly
fitted and there should be no gaps.
b. After the screw machine is installed, check whether there is
enough lubricating oil in each oil storage place, if not enough,
add enough, and then carry out a no-load test run; check the screw
machine after running for more than 4 consecutive hours. Accuracy
of assembly: Stop immediately when an abnormality is found, and
operate after treatment until it is in a good operating state.
c. The operation of the screw machine should be stable and
reliable, and the fasteners should not be loosened. The reducer has
no oil leakage, no abnormal sound, electrical equipment is safe and
reliable, and the no-load operating power is less than 30% of the
rated power.
