Stack sizer is very important equipment in the ore mining industry. Stack sizer is composed of pocket, feeder, screen, rubber spring, wear resistant polyester mesh screen, electric vibrator, bracket, collection, etc. Stack is composed of up to five individual screen decks laying one above the other and operating in parallel. In all of the components of the stack size, the screen is the most important part. Screen plays a vital role in efficient classification. After continuous efforts, industry personnel finally create screens made of polyurethane. It soon becomes the mainstream of sieve industry.
Everything that becomes popular must have its own reason. As to polyurethane screen , the reason is that it has many good features that other screen cannot compare with.
1 High wear resistance, long service life
Ammonia ester elastomer known as “the king of wear-resisting”, “liquid steel”, is a kind of new synthetic material between rubber and plastic, with high wear-resistance, wide hardness range, and high elasticity, high tear strength. Its service life is 8 to 10 times higher than ordinary metal sieve plate. It is currently the best screen surface material in the aspect of wear-resisting performance. Its service life can reach more than six months. The raw material of polyurethane sieve plate goes through special processing to make sure that it will never take off under long-term fluctuating load loading.
2 Perfect self-cleaning performance and good anti-blocking performance.
Due to the high elastic polyurethane sieve, screen effectively avoid the wet particle adhesion and ensure that the screen hole will not block when the stack sizer is screening limit size particles. This effectively makes up for the defect of polyurethane screen mesh poor opening rate, leading to high separation efficiency. Using inverted triangular mesh has solved the problem of mesh plug both from theory and practice.
3 High opening rate, large handling capacity per unit area
Wire mesh can be done to minimum 0.2 mm; mesh opening rate can reach thirty percent. This is three times more than ordinary mesh.
4 Energy saving
Polyurethane screen is light in weight and small in dynamic load. So power consumption is small when sieve machine is driving screen mesh, which can increase the capacity, improve the production efficiency, and reduce the noise in running process. Polyurethane screen is helpful to improve the working environment.
5 Easy to maintain and repair
Polyurethane screen is very light and easy to clean. It is easy to install and convenient to replace or maintenance. What’s more, the screen is suitable for any type of screening. In a word, the screen greatly reduces the workload of the workers.
Polyurethane screen in stack sizer is suitable for many kinds of stack sizer. It is suitable for metallurgical, coal, chemical industry, building and many other departments. If someone wants to do a good job, he must first sharpen his tool. Therefore in the future, polyurethane screen surface is the perfect option of the vast majority of enterprises.
