As one of the widely used equipment in the industrial field, the selection of the screen plate has a vital influence on the screening effect, equipment life and economic benefits. Therefore, the reasonable selection of vibrating screen is an important part of ensuring the smooth production and improving the screening efficiency.
1. understand the basic types of sieve plate vibrating sieve sieve plate in accordance with the material, structure and use of different, can be divided into many types. Common sieve plate materials are stainless steel, rubber, polyurethane, etc., of which stainless steel sieve plate is wear-resistant and corrosion-resistant, and is suitable for screening a variety of materials. Rubber sieve plate has good elasticity, small impact on materials, and is suitable for fragile materials. Polyurethane sieve plate has self-cleaning function, is not easy to block, and is suitable for materials with high humidity.
Structurally, the sieve plate can be divided into woven type, slit type, punching type, etc. The woven sieve plate has good air permeability, but is easy to deform; the slit sieve plate has simple structure and high screening efficiency; the punching sieve plate can be customized according to the needs of the aperture, which is suitable for screening materials with different particle sizes.
2. according to the material characteristics of the choice of sieve plate 1. material particle size: sieve plate aperture size should be selected according to the size of the material to be screened. For materials with coarse particle size, the sieve plate with larger aperture should be selected; for materials with finer particle size, the sieve plate with smaller aperture should be selected.
2. Material hardness: The hardness of the material determines the degree of wear of the sieve plate. For materials with high hardness, the sieve plate with good wear resistance should be selected, such as stainless steel sieve plate; for materials with low hardness, the sieve plate material with low cost can be selected.
3. Material humidity: materials with high humidity are easy to block the sieve plate and affect the screening effect. At this time, the sieve plate with self-cleaning function should be selected, such as polyurethane sieve plate, or the larger aperture and slit design should be adopted to reduce the clogging phenomenon.
4. Material viscosity: viscous material is easy to adhere to the sieve plate, affecting the screening efficiency. For this type of material, you can choose a smooth surface of the sieve material, such as stainless steel sieve, or the use of vibration intensity of the vibrating screen equipment, reduce material adhesion.
3. consider the service life and cost of the sieve plate The service life and cost of the sieve plate are important factors to consider when choosing the sieve plate. Sieve plates of different materials and structures have different service life and cost. When selecting the sieve plate, the running time of the equipment, the material handling capacity, the screening accuracy and other factors should be considered comprehensively, and the sieve plate with high cost performance should be selected.
At the same time, the maintenance and replacement costs of screen plates should also be taken into account. Although some screen plates have low initial costs, they are frequently maintained and replaced, which will increase the overall cost. Therefore, when choosing a sieve plate, factors such as its service life, maintenance cost and replacement cycle should be considered comprehensively.
4. Refer to the equipment manufacturer's recommendations The equipment manufacturer will usually provide recommendations for the selection of the sieve plate based on the model, specification and use of the equipment. These recommendations are based on the manufacturer's in-depth understanding of equipment performance, material characteristics, and actual production experience, and have high reference value. When selecting a sieve plate, you can consult the equipment manufacturer for professional advice and guidance.
5. summary The selection of vibrating screen plate involves many factors, including the basic type of screen plate, material characteristics, service life and cost. When choosing a sieve plate, these factors should be taken into account to choose the sieve plate that best suits your own production needs. At the same time, you can refer to the equipment manufacturer's recommendations for professional guidance and help. Through the reasonable selection of the sieve plate, the normal operation and efficient screening of the vibrating screen equipment can be ensured, and the production efficiency and economic benefits can be improved.
