Various frame materials can be added to the polyurethane screen plate during the molding process to extend its service life. Polyurethane screens are lightweight and easy to load and unload on site.
The polyurethane screen plate has good elasticity, which can increase the jumping frequency of materials and improve screening efficiency. The polyurethane screen plate has high resistance and low noise. Polyurethane screen plates can be designed with different hole shapes according to the shape of the material.
The vibration motor is the vibration source of the vibrating screen machine, and the exciting force is determined according to the size and material handling capacity of the vibrating screen.
The size of the vibration motor used varies with the weight and handling capacity of the screen machine. If the excitation force is too large, the vibrating screen will break due to the excessive excitation force. If the excitation force of the vibration motor is too small, the processing effect cannot be achieved. Because the excitation force is too small, material accumulation and blockage may also occur.
The larger the screen holes, the higher the productivity per unit screening area and the higher the screening efficiency. However, the size of the mesh depends on the purpose and requirements. If you want to minimize the distribution of fine materials on the sieve for materials smaller than the sieve openings, a smaller sieve opening should be used; on the contrary, if the material under the screen is required to contain particles larger than the specified particle size as much as possible, the sieve openings should not be too large. . The specified particle size is the sieve width limit.
The vibration or jumping frequency of various materials on the screen plate and screen can increase the screening capacity of the materials. Additionally, the bonds between separable materials increase the amount of loose particles that can pass through the screen.
