The S49-A series ternary vibrating sieve mesh parent structure consists of three parts: subnet, parent grid and grid. The screen is a two-layer laminated structure, wherein the lower layer is a coarse sieve cloth, which mainly serves as a support, and the upper layer is a fine sieve cloth for sieving. The SZF series of light linear vibrating screens are generally composed of subnets, parent grids, grids, and lowermost support nets/boards. It is well known that the screen is a wearing part, it should be replaced frequently, and some even need to be replaced once every 2-3 days. So how should the customer choose the screen when purchasing the vibrating screen? There are generally two ways:
1. Determine the screen standard according to customer needs and industry needs
2. Determine the wire diameter and aperture of the screen according to the customer's screening material; for example, if the customer's screening demand is decontaminated, then the requirements of his screen aperture are not the main ones, mainly based on the model and material selection. The wire diameter and pore size of the screen.
Case number one:
Soy protein, the purpose of this material screening is to remove large impurities and agglomeration, so the mesh requirement of the screen is a rough digital concept, and the wear of the material on the screen is very small, each sieve of the customer The net can be used for 3-6 months, but the customer pays great attention to the output. At this time, it is important to select the quality standard of the screen;
Preferred standard: pore diameter 0.3mm wire diameter 0.112mm mesh mesh number: 61.7 mesh (effective screening area of ​​this standard sieve: 53%);
The second scheme: access aperture: 0.28mm wire diameter 0.14mm mesh mesh number: 60.5 mesh (effective screening area of ​​this standard sieve: 44%);
The third scheme: access aperture: 0.25mm wire diameter 0.16mm mesh mesh number: 62 mesh (effective screening area of ​​this standard sieve: 37%);
The same material, the same effective screening area produced by different standard screens can be analogized, and the output can also be analogized.
Case 2:
The customer screening material is the raw material of aquatic feed (the material is composed of aquatic feed additive such as flour and bone meal, the specific gravity is 0.8, which is an oily product with almost no liquidity, used to make broken aquatic products and puffed aquatic feed, etc.), and sieved The demand is to remove large impurities and agglomeration. Generally, 12 mesh to 20 mesh can be used to meet the requirements of the next process. The output demand is large. The model is SZF series linear vibrating screen. Because the customer's equipment is generally placed on the high platform, The difficulty and convenience of changing the screen is the key point for us to meet the demand. In order to reduce the frequency of changing the screen, the wire diameter of the screen is selected as coarse as possible.
Case 3:
The material sieved by the customer is aquaculture broken material. The purpose of sieving is generally grading. Most of the models used are S49-A series, mesh number: 12 mesh, 16 mesh, 18 mesh, 20 mesh, 24 mesh, 30 mesh. 40 mesh, etc., because the customer will change the screen at any time according to the demand, so the screen wire diameter can not be selected thicker, otherwise it will bring difficulty to the assembly of the screen.
It can be seen that the selection of the screen network also needs to consider many factors. The high-performance screen machine has undergone 28 years of practice development and follows the behavioral values ​​of “customer satisfaction without excusesâ€, and has created excellent performance for thousands of enterprises at home and abroad. The screening machinery meets the different needs of customers. Created significant production benefits for our partners. The high-service screening machine will, as always, base on Xinxiang, face the whole country, go global, and actively lead the development of the screening industry. We believe that the future of "high service" will be even better, and the international influence of China's national industry will become stronger and stronger!
