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.

How to Select and Install Screen Cloth of Linear Vibrating Screen

The selection and installation of screen cloth is very important for linear vibrating screen. Select the most suitable screen cloth and install it according to correct way can improve the performance and prolong the service life of the linear vibrating screen.
1. How to select the most suitable screen cloth?
a. Because it is complicated for screen cloth installation of linear vibrating screen, we should select the screen cloth with thicker wire diameter.
b. While cutting screen cloth, we should keep the width of screen cloth consistent with the mesh frame, length should be 50-70mm longer than mesh frame.
2. How to install the screen cloth of linear vibrating screen?
a. Since the tensity of screen cloth will affect the screen efficiency directly, we should keep the screen cloth tension during installing the screen cloth.
b. Please confirm whether needs to add the bouncing balls according to mesh size and difficulty level of the screened material.
c. We should add suitable supported mesh size under the screen cloth if the mesh of the screen cloth is high or bulk density of the material is big.
d. While install the pressing plate, we should keep the flatness of the plate and line with strong scalability sponge sealing to lock it uniformly.
e. After completing installation, we should test the condition of feeding material and screening with few materials. If materials run forward uniformly, classify accurately without mixing phenomenon,linear vibrating screen can be used well. If not, we should adjust the linear vibrating screen mesh and test again.

Application & Development of Vibrating Screen in Food Industry

Vibrating screen used in food industry is a kind of high efficiency screening machinery for high precision fine powder and other materials , which is easy to operate, fully enclosed structure, suitable for granular, powder, mucus and other materials screening and filtering classification. 
Such as powdered sugar, starch, salt, rice flour, milk powder, milk, egg, soy sauce, vinegar, fruit juice, papaya powder, green tea powder, kudzu powder, and potato processing production which are commonly used in daily life,vibrating screen will be a good helper. 
Take starch or rice powder as example, usually the first procedures : impurity removal of raw materials - screening-weighing;secondly , soaking- coarse grinding-germ separation-fine grinding-screening of starch-protein separation-centrifugal dewatering- thermostatic drying, lastly,weighing-product packing. We can not imagine how to deal with the screening in the process of food without vibrating screen. Vibrating screen overcomes the difficulty of fine material screening easily, which also makes food diversified and entire food industry develop rapidly.
