How to Select the Driven Device for Linear Vibrating Screen ?

Linear vibrating screen can achieve dry and wet screening,and also can achieve automation work on the working site. Here PK Machinery will talk about the driven device selection for linear vibrating screen. 
With regard to the material like ceramic, food, etc with small density,capacity and vibrating screen model, generally the screen surface length is <3000mm, screen surface width is <1200mm, and the weight of the vibrating screen is relative light, under such circumstances, the driven device of 2 sets vibrating motors rotate oppositely at the same time will be adopted. Motor installation on the bottom, upside or both sides of the screen equipment can be optional.

While the material like coal, mineral, building material, etc with large density, capacity and the required vibrating screen model, generally the screening surface length is >3600mm, screen surface width is >1500mm, and the weight is heavy. Under such circumstances, the driven device of 2 sets motors drive 2 sets vibrating exciter will be adopted. Vibrating exciters will rotate in different directions which can be installed on the bottom or the upside, then produce vibrating exciting force to achieve screening. 
If the working site’s installation space is limited, or there are some special requirements, we could optimize the design.

What should we notice when use linear vibrating screen for the first time？

Firstly, check if there is bolt looseness of the linear vibrating screen.
Secondly, remove four fixed plates of all the springs on the linear vibrating screen in order to protect the machine from scratch during transportation process.
Thirdly, read the manual carefully and check the components before testing the linear vibrating screen.
Besides,please also note the following important notes:
1.Since vibration motor works continuously, it needs to be filled with oil regularly .
2.Check if there is screen mesh damage when the machine stops working.
3.As some users may choose wood net rack, please also check if there is screen frame damage. Compared with steel net rack, the wood net rack is easy to replace screen mesh,however, the life span is much shorter. 

What's the Special Role of Vibrating Screen Bouncing Ball?

When the vibrating screen works, have you ever noticed that the bouncing balls beat up and down on the sieve mesh? Why this phenomenon occurs on the sieve mesh? What's special role of bouncing ball? Today we will take a brief look.
These bouncing balls are an essential part of vibrating screening machines.Its role is beating the sieve mesh up and down avoid adhesion material blocking the sieve mesh which can improve screening efficiency and accuracy.

Bouncing balls are generally divided into different diameters: φ10, φ15, φ20, φ25, φ28, φ30, φ40, φ50, φ60 and so on, commonly used ones are φ25 and φ28 , φ40, φ50and φ60 mainly used for mine vibrating screen.
According to the material,bouncing ball can be classified into several types: rubber ball, silicone ball, PTFE ball bouncing, according to different materials of bouncing balls, the application and function is also different.
Natural rubber bouncing ball：it is suitable for general material screening process;
Silicone bouncing ball：good elasticity., mainly used for food, medicine and other materials screening;
PTFE bouncing ball : It can soak in the oil , mainly applied to oily liquid materials screening.
The bouncing balls should be selected based on different material properties to meet customer requirements in different conditions. Though bouncing ball is a small accessory, it is the key to solve the problem of screening.

Application of Dewatering Screen in Beneficiation Process of Potash Feldspar

Recently, most of manufacturers choose spiral classifier and pressure filter to dehydrate potash feldspar during dehydration process. But there are some disadvantages, spiral classifier cannot classify materials completely and pressure filter needs large investment. What’s more, if users adopt spiral classifier to deal with the separation of residue water during the production of potash feldspar, it will cause the finished materials containing too much water so that the materials cannot be dry heaping. It is found that if users adopt dewatering screen instead of spiral classifier, the water content of potash feldspar will be less than 15% after dewatering by dewatering screen and the materials can achieve dry heaping effect. Furthermore, it can increase recovery rate of finished products because the dewatering screen can elect fine sand which will lose caused by spiral classifier.

 

There are two applications for dewatering screen used in beneficiation process of potash feldspar, one is used for classification of potash feldspar which is processed by ball mill, another is used for dewatering of potash feldspar products. In the traditional production process, it always uses pressure filter to deal with this kind of materials during the dewatering process of potash feldspar products. But this kind of production technical has large energy consumption, lower working efficiency and higher water content. While if users adopt dewatering screen to deal with potash feldspar, it can improve the production efficiency greatly, also can reduce energy consumption and floor space.
