  • JD mill internal screening dev
  • JD screw-type screening device is a high-efficiency screening device successfully developed by jedda company and obtained the national patent, which can effectively improve the output of closed-circuit screening and grinding station, increase the specific surface area of cement, improve the strength of cement, and can be mixed with more materials. Its structure is the number of pieces of crescent pores of sieve plate combined into screw structure, filling in the spiral screen plate material after rotation to a certain height, under the dual role of gravity and pile pressure on the sieve plate cant drop top-down process of screening, lead into the second warehouse mill for grinding, coarse particles are returned to finely a storehouse.


    JD screw-type screening device overview

    At present, most of the sieving plates in the double-layer sieving compartments of the ball mill are vertically arranged, and the sieving force when the materials pass through the sieving seams of the sieving plates is the lateral packing pressure of the materials. However, due to the small height of the accumulation, the accumulation pressure is weak, so the material screening speed is slow, screening efficiency is low.

    JD screw-type screening device is a high-efficiency screening device successfully developed by jedda company and obtained the national patent, which can effectively improve the output of closed-circuit screening and grinding station, increase the specific surface area of cement, improve the strength of cement, and can be mixed with more materials. Its structure is the number of pieces of crescent pores of sieve plate combined into screw structure, filling in the spiral screen plate material after rotation to a certain height, under the dual role of gravity and pile pressure on the sieve plate cant drop top-down process of screening, lead into the second warehouse mill for grinding, coarse particles are returned to finely a storehouse.

    It has been proved by many manufacturers that when the width of the screen joint is reduced to 1.5-2.0mm, its passing capacity can fully meet the requirements of closed high fine grinding. The use of materials can be highly efficient grinding, because the gap of the screen plate further smaller, for the use of the original micro-forging to create conditions, can further improve the grinding efficiency of the mill, let the mill more qualified finished products.
