What Should We Notice When Operate the Rotary Valve

What Should We Notice When Operate the Rotary Valve

Please pay attention to the following operation notes,hope it is helpful for you:

1.If motor is overheat when start up,please stop and inspect it, in order not to affect normal operation of the reducer.

2.Reducer must be operated as per the operating manual and the rotating direction must rotate according to the arrow direction as shown.

3.If powder leakage phenomenon occurs on the shaft, please tighten the packing gland bolts at both ends.

4.During operation , check bearing heating circumstance, general bearing temperature rising shall not be over 60 ℃.

5.During operation, if abnormal vibration occurs, please stop the machine and eliminate the abnormal phenomenon.

6.If there is bolt looseness in the process of operation, please tighten the bolt.

How to Select and Install Screen Cloth of Linear Vibrating Screen

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

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.
