Product description
What factors determine the screening effect of circular vibrating screen? Vibrating screen in the production process will often appear enrichment phenomenon, that is, the screen is blocked, the effective screening area becomes smaller, the process efficiency is reduced, which is mainly related to the material type and particle, material loose density, material particle size, material particle composition.
The type of material treated by circular vibrating screen is different, and the physical characteristics are different. The type of material can be divided into two categories: brittle and viscous, viscous material in the process of vibrating screening, easy to form the dense adhesion of the material, blocking the screen, so that the permeability is reduced, and brittle material is not, the process efficiency can be guaranteed. The particle shape of the material will also affect its sifting rate. The material of cube opening and sphere is easy to sift through, while the sheet material is easy to get stuck in the sifting hole, which reduces the efficiency of the sifting process.
The material particles treated by circular vibrating screen are basically stratified and screened according to the size of the particle volume, that is, the loose density of the material directly affects the processing capacity of the vibrating screen. The bulk material with large loose density is easy to pass through the screening, and the screening efficiency is higher. On the contrary, the less loose density of materials and powder materials are not easy to pass through the screening, screening efficiency is low.
The water content of the material treated by the circular vibrating screen is too high, easy to form adhesion. In the process of vibration, the block extrusion makes the adhesion more dense, increases the resistance of the material movement, and makes the material material layering and sifting difficult; Material adhesion also reduces the size of the screen, clogs the screen, reduces the effective screening area, and sometimes even cannot be screened. Therefore, when the water content of the material is too high, some remedies should be considered in the screening process, such as drying the material and other measures.
The material treated by circular vibrating screen in the screening process of screening probability is affected by many factors, among which the direct and important factor is the material size and the relative size of the screen size. The ratio of material size to screen size is called relative size. The smaller the relative grain size is, the higher the screening probability is. When the relative grain size is close to 1, the screening probability is close to zero. Therefore, the material with relative particle size equal to 0.7-1.0 is usually called difficult screening material or critical material. Material in the difficult screening material composition also has an impact on the probability of screening, the greater the content of difficult screening material in the material, the smaller the probability of screening, screening efficiency will be lower. In order to achieve higher screening efficiency, the content of difficult to screen material in aggregate should be reduced as far as possible. In addition, the difference of particle size index also has a certain impact on the screening efficiency. If the difference of particle size index is too large, the production cycle will be large, restricting the quality and processing capacity of the product. Therefore, the aggregate should be strictly controlled.
About Transportation
After you place the order and pay the deposit, we will start to arrange the production and contact the ocean freight transportation agency to reserve the position. Two days before the end of production, you need to complete the final payment. Then, we inform the ocean cargo transportation agent company that it is ready to come to the factory to pull the goods to the port. On the day of delivery, we will send the customer the factory video and pictures, and mark the corresponding English name of each product and product parts with a marker to prevent the customer from not knowing what each part is after receiving the goods. At the same time, we will put the English version of the product instructions in the cargo box. We generally select freight forwarders with preferential prices for customers to deliver goods for you. The shipping method can be FOB or CIF. You can also choose EXW, and then contact the goods agent company yourself.
