Relaxation sieve is a new type of screening machine developed in the early 1980s. The screen is made of stretchable polyurethane rubber material. During operation, the screen is alternately tightened and slackened to make the material produce forward bounce. It can prevent the material from adhering to the screen and blocking the screen hole. At the same time, due to the use of flexible sieve plates, the projectile acceleration reaches 30~50 times of the gravity acceleration, and the maximum amplitude of the sieve plate can reach 40mm. Therefore, the mesh hole is not only easy to block, but also the screening efficiency is improved, the processing capacity is large, and the dynamic load is small. Low power consumption and low noise.
At present, saddle-type flip-ore production CZS sieve screen surface as a single layer, have a different mesh size, seat-mounted, may be used for larger ore, coal, gravel, municipal wastes viscosity, water content 7% to 14 %, the classification of difficult-to-screen materials with a particle size of 0~l00rnm, the graded particle size is 1~30mm, especially suitable for the deep screening of medium and fine-grained coal. The technical performance and parameters of the relaxation screen are shown in the table below. The dimensions and installation dimensions are shown in the figure below. In addition, the South Mine produces four types of CZS relaxation sieves, which are mainly used for screening coal, fertilizer and slag.
Model meaning example CZS2055: CZS - relaxation screen, 20 - screen width (dm), 55 - screen length (dm).
