Weight loss type feeding system for key points
Author:Batte. Click:

s we all know, weightlessness feeding system is a conveying equipment for bulk materials. On the one hand, the weightlessness feeder can convey fine materials with particle size less than 5 mm, on the other hand, it can also convey bulk materials with side length more than 1 m. It has the advantages of continuous and uniform transportation, adjustability and strong adaptability. Therefore, it is widely used in the material processing production line of building materials, metallurgy, electric power, coal, chemical foundry and other industries. In cement industry, it is used for the transportation of massive limestone or gypsum from the bottom of the ore bin to the crusher, playing a continuous role. Uniform feeding can greatly improve work efficiency.

There are three ways to solve the problem that the weightlessness feeder can not be overloaded.

First, to reduce the impact of ore on the weightlessness feeder, the traditional method is to reduce the inclination angle of the back wall of the silo by testing according to the specific conditions of each unit. However, this method will make the material slide slowly and have a negative impact on production. In order not to affect production on the one hand, on the other hand, it can solve the impact problem. The grain size of the ore into the silo should be limited, if it must be less than 800 mm, the thickness of the rear part of the weightlessness feeder should also have certain requirements, if it must be more than 1 meter;

Secondly, the impact resistance of the weightlessness feeder can be enhanced by strengthening the support beam at the rear of the weightlessness feeder and the impact resistance of the rear slideway of the weightlessness feeder.

Thirdly, the starting ability of the main motor of the weightless feeder can be improved by checking. After general force analysis, the results show that the main reason why the weightless feeder can not start under heavy load is that the starting torque of the main motor of the weightless feeder does not match the load torque. Therefore, the main motor of the weightlessness feeder is replaced, and the main motor of the weightlessness feeder can be selected, which is economical and can meet the requirements of heavy load starting.
