Why Circular Vibrating Screen can not Start up and Amplitude is Small ?

Days ago,my Russian friend asked me why circular vibrating screen could not start up,however,the amplitude was quite small even if it start up,and the screening efficiency is quite bad,here I summarize the reasons as follows:
1.The circular vibrating screen motor breaks down,please replace the motor;
2.The electrical equipment control circuit fails,please maintain and replace the electrical equipment;
3.The voltage is low,you can alter the power supply;
4.There are many accumulation materials on the surface,please clean up the material;
5.The screen itself has fault,please check and maintain the vibrating screen;
6.The lubricating oil is over thick or caking,please clean the screen and add new lubricating oil;
7.You can also add balance weight to increase the amplitude.
Besides,please also note that the adjustment of vibration source on vibrating screen(exciter or vibrating motor) must be same,or it will cause equipment damage.

What reasons lead to linear vibrating screen motor base crack ?

All users know that the vibration motor is the vibration source of linear vibrating screen , it will bring inconvenience of operation if the vibration motor base cracks and damages. Here are some analysis reasons for you:
1. Too large motor power ,model selection and exciting force which exceed the normal load of vibrating screen, it will cause damage of motor base for long time operation
2. Too thin steel plate thickness design with long time operation will cause crack.
3. There is a problem with steel plate material.
4. Welding quality can not meet the requirements.
5. The installation position of the motor does not conform to the design requirements of the vibration dynamic specifications.

Instruction of Trommel Screen

Trommel screen is composed of motor, reduction unit, cylindrical drum, screen frame and sealing cover. Cylindrical drum screen is normally elevated at an angle at the feed end.Classify
      1. Functions: configured for classification, screening, grading
      2. Type: open type, closed type
      3. Classification: shaft rotary screen, shaftless rotary screen
      4. Construction: carbon steel, stainless steel
      5.Applications Scope: widely used in chemical, coal, construction, gold mine, plastic,quarry,recycling, metallurgy, mineral-selecting industries, etc.


trommel screen
► Working principle
When material flow towards along the inclined rotating drum,materials jump and roll , the undersized material smaller than the screen apertures passes through the screen wire mesh, while the oversized material passes out at the other end of the drum.
► Advanage

    1.Steady and smooth operation.
    2.Low noise and low energy consumption.
    3.Simple structure with easy maintenance.
    4.Suitable to separate various materials especially poor quality of coal and coal slime.
    5.Equipment is fully sealed with cover in order to minimize the suspension of fine materials in the air during the operation. Low dust pollution.
    6.High screening efficiency due to installation of comb shape screen structure.
    7.Cylindrical shape of the screen provides larger surface area for the materials to in contact with. Able to handle large capacity of materials with high efficiency.
    8.Long life span.
► Features
    1.Smooth operation, low noise,low energy consumption
    2.Simple structure, convenient maintenance
    3.Trommel screen sieve can be sealed designed, no dust pollution
    4.Special screen mesh design, high screening efficiency, longer service life, less blockage


drum screen
► Application
Trommel screen sieve is applied to compost, chemical, coal, construction, gold mine, plastic, recycling,metallurgy,mineral-selecting,agriculture etc.
