Reasons and Solution to Abnormal Start of Screen

As we all know that it is a piece of common knowledge that we will often fit out screen machine in the stone manufacturing and production line. This screening equipment is a vibrating and screening machine device which is suitable for dry screening the kind of material that has a high degree of water content and that is different to sieve it well.

This kind of machine manufactured by Honging Machinery earns this name by reason of its approximately circular movement. It is of multilayer and high efficient. The eccentric shaft vibration exciter and partial block help to adjust amplitude. This kind of screening equipment is of long streamline, clear screening for different specifications. It is widely used for grading and screening materials in the fields such as coal-selecting, mining-selecting, building materials, electrical power and chemical industry, etc. The vibrating equipment is used to separate materials. It is composed of main frame, screen, motor, eccentric bock, rubber spring, coupler and etc. Our company supplies suitable type according to customers’ demands. The features are as follows: simple, reliable, high screening capacity and high durability.

moves round. It has multi-layers and is of high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. The material drops down along the long line. In screen grading, the material is separated mechanically on screen plates. Rolling bearings in vibrating screens are stressed by high, mostly shock-type loads. Moreover, the bearings, while rotating about their own axis, perform a circular, elliptical or linear vibrating motion. This results in high radial accelerations which additionally stress the bearings, and especially the cages, considerably. The operating speeds are usually very high. As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications. In addition, considerable misalignments between the bearing locations and considerable shaft deflections have to be accommodated.

If it cannot be started in a normal way, then the customer should immediately stop the equipment and make a comprehensive check and examination. If the causing reasons are not within the following points, then you may consult the relative personnel, and our engineers and technicians will timely answer your questions or get to the working spot to clear and solve your problems. And the following abnormal start is concluded by the technicians in Hongxing Machinery according to the customers’ demands and we hope that these solutions can make you feel relieved if the same or related problems happen to your machines.

(1) The needed electric voltage for the vibrating screen is 380v so please make sure that you are using three boxes of power.

(2) If the motor is damaged, please change it in time.

(3) If the machine component that is used for controlling the circuit is damaged, please change it.

(4) When the electric voltage is not sufficient, the customer can solve the problem by changing the power supply.

(5) When there is a lot of material on the screen surface, please clean it.

(6) If the exciter breaks down, please examine and repair the exciter.

(7) When the lubricating grease becomes thick and packed, the exciter should be cleaned and need to replace suitable lubrication grease.
