The shale shaker, such as VSM shaker and brandt shaker , is very useful in many different industries. So the screen basket is important. The shale shaker screen basket is mainly used in dehydration of centrifugal dehydrator, widely used in coal, chemical industry, metallurgy and other industries. The shale shaker is a high-speed rotating component. When it works, it has to bear not only the vibration load, but also the severe impact of coal and water. So the strength and accuracy of requirements are high.
As everyone knows, the shale shaker screen basket is vulnerable. The using limit of the same screen basket is not the same according to different characteristics of the material and screen machine running time. The frequency of changing the screen basket is high when the proportion of material is large or the material’s shape is irregular. On the contrary, the frequency is relatively low when the proportion of material is small or the shape is regulation. You should pay attention to choose the long using-limited and non-easily damaged shale shaker screen basket when you change it. So it is the most concerned question of each user how to choose a proper shale shaker screen basket according to the characteristics of material? I hope the following tips can give you some reference.
Firstly, you should determine the type of the shale shaker screen basket according to the industry standard requirements. Please notice one thing: the screen basket is processed in the particular standards of machine. No matter how good the screen basket is, it will appear deviation, the number of screen mesh especially. When you choose it, please be sure to communicate carefully with technical staff.
Secondly, you can determine the screen the diameter of wires and meshes according to the screening material. For example, if you are intent to filtering impurity instead of grading the material, you should select the screen the diameter of wires and meshes according to the type of shale shaker and characteristics of material.
Thirdly, screen mesh precisely effective screening area can only represent specific screen. If you require a higher accuracy of screening, you must let the suppliers to provide the detailed standard to confirm the size of mesh.
Fourthly, the shale shaker screen basket must be weaved in the same strength horizontally and vertically. You can pull it from any direction but you can’t shake it.
Fifthly, each side has to tie knots. In this way the screen basket will not be vibrated off easily by the vibration of the shale shaker.
You should not choose the cheap shale shaker screen basket. On one hand, the cheap screen basket is not durable. On the other hand, the cheap one is not accurate. If the size of mesh is not accurate, it can lead to the different sizes of material. The purpose of using screen basket is to separate materials according to the size. You can't achieve this aim with the cheap shale shaker screen basket. So you’d better choose it according to the above tips.
