Detailed description of the performance characteristics and applications of polyurethane screens

Polyurethane screen has performance characteristics and is increasingly used. Here are some reasons why polyurethane screen is used. The service life of highly wear-resistant polyurethane screen is 3-10 times higher than that of metal wire mesh, which improves the operating rate and economic benefits.
The unique structure, appropriate elasticity and elastic force can not only squeeze the blocked materials through the sieve holes or escape from the sieve holes to become the under-sieve or over-sieve products, but also prevent the fine particles from adhering due to the secondary high-frequency vibration of the screen bars. It significantly reduces the blockage and cleans the product surface. It improves the screening efficiency.
Polyurethane screen effectively absorbs impact, reduces noise, and improves the working environment. It is horizontally tensioned, light in weight, flexible, easy to install and disassemble, and easy to transport and store. Installing polyurethane screen can extend the service life of the crusher. The ores mined in the mine are irregular and have large particle sizes, and cannot be directly put into the ball mill for grinding.
In order to reduce the cost of ball mill, the ore is crushed and then put into ball mill for dissociation. The dissociation stage before entering the ball mill is the crushing stage of ore dressing. The general crushing process is: coarse crushing -> medium crushing -> screening, the undersize after screening -> ball mill; the oversize after screening -> fine crushing -> screening again. This is the common three-stage and one-closed-circuit crushing process.
