baking pans Difference between shaker square hole sieve sieve with round holes

Difference between shaker square hole sieve sieve with round holes

sieve and the merits of the square hole sieve shaker hole : round hole sieve are punching screen ,baking pans, the screening of high precision , easy to wear , long life , but the screen surface openings rate is low ,baking pans, generally 50% through effective screen area is small, screening slower , lower yield . To solve this problem , the expansion of the conical bottom of the sieve is made , namely, the formation of an inverted cone hole , sieve , from the entrance to the exit gradually expanded , conducive material through the sieve . Sieve surface is a square hole sieve, generally woven its opening rate,baking pans, the total screen area of up to 70 percent ,baking pans,Difference between shaker square hole sieve sieve with round holes, effective through the sieve area and difficult to pore blocking , screening speed high yields . Compared to the sieve , its poor robustness , screen life span is short ,baking pans, easy deformation ,Difference between shaker square hole sieve sieve with round holes, deformation part of the mesh shape and size will change .
shaker screening efficiency factors in addition to the nature of the materials ( grain size, shape, moisture , etc.) , as well as the screen surface of the structural parameters ( the width of the screen surface , length and mesh size , shape and open porosity ) , sieving machine kinematics parameters ( amplitude ,baking pans, the number of vibrations n sieve inclination , etc.) and process parameters ( such as productivity and material thickness , etc.) . When the screen material and sieve machine structure is determined , the factors that affect the screening efficiency of the screening machine amplitude λ, the number of vibrations n sieve inclination angle α0 and productivity Q .
