polyurethane sieve plate for vibrating screen/Johnson screen

Polyurethane sieve plate: it makes full use of the good wear resistance, high strength, high elongation and high elasticity of polyurethane elastomer, good shock absorption performance, oil resistance, low temperature resistance and other properties, as well as its reasonable screen structure and installation structure design, so that the mining polyurethane sieve plate has the following characteristics:

1. 耐磨性能好：使用寿命长，其耐磨性为钢制筛板的3-5倍，为普通橡胶筛板的5倍以上。

1. Good wear resistance: long service life, its wear resistance is 3-5 times of steel sieve plate and more than 5 times of ordinary rubber sieve plate.

2. 降低维修率：聚氨酯筛板不易损坏，使用寿命长，因此可以大大降低维修量和停产检修损失。

2. Reduce the maintenance rate: the polyurethane sieve plate is not easy to be damaged and has a long service life, so it can greatly reduce the maintenance amount and maintenance loss.

3. 总成本低：尽管同一规格（面积）的聚氨酯筛板比不锈钢筛板一次性投资高（约两倍），但由于聚氨酯筛板寿命是不锈钢筛板的3-5倍，而且维修和更换次数少，所以经济适用是zuijia选。

3. Low total cost: Although the one-time investment of polyurethane sieve plate with the same specification (area) is higher than that of stainless steel sieve plate (about twice), the service life of polyurethane sieve plate is 3-5 times longer than that of stainless steel sieve plate, and the maintenance and replacement times are less, so Zuijia's choice is economic and applicable.

4. 耐湿性能好：可在水为截止的条件下工作，且在水、油等介质的情况下，聚氨酯与物料的摩擦系数降低，更利于透筛，提高筛分辨率，并可避免潮湿微粒的粘附，同时因摩擦系数减低，磨损减少，使用寿命提高。

4. Good moisture resistance: it can work under the condition of water as cut-off, and in the case of water, oil and other media, the friction coefficient between polyurethane and materials is reduced, which is more conducive to screen penetration, improve screen resolution, and avoid the adhesion of wet particles. At the same time, due to the reduced friction coefficient, the wear is reduced, and the service life is improved.

5. 防堵塞：由于筛孔设计合理，筛板制造工艺独特，尺寸的颗粒不会阻塞筛孔。

5. Anti clogging: due to the reasonable design of the screen hole and the unique manufacturing process of the sieve plate, the size of the particles will not block the screen hole.

7. 吸振性能好：消声能力强，可减少噪音，并可使筛上物在震动的过程中不一破碎。

7. Good vibration absorption performance: strong noise elimination ability, can reduce noise, and can make the screen material in the process of vibration is not broken.

8. 聚氨酯筛板具有自清理作用，因此筛分效率高。

8. Polyurethane sieve plate has the function of self-cleaning, so the screening efficiency is high.

9.节能降耗，聚氨酯比重小，比同样大小刚筛重量轻的多，从而减轻了筛机负荷，节约电耗，并可延长筛机寿命。

9. It can save energy and reduce consumption. The proportion of polyurethane is small, and the weight is much lighter than that of the same size rigid sieve. Therefore, the load of the screen machine is reduced, the power consumption is saved and the service life of the screen machine can be extended.
