MOR Composite Sand and Casting Screening and Grinding Drum

This machine is mainly used for shakeout cleaning of batch production of cast iron, cast copper, and cast aluminum parts, as well as for slow cooling of the workpieces. It is equipped with a dust removal sheet with a recommended dust removal capacity of 10000～12000m3/h. It can improve the cooling effect, capture the ash powder content in the low old sand, increase the wet compressive strength and air permeability of the molding sand, and thus improve the casting yield. Its overall performance is relatively good. The size of the cleaned workpiece should be less than 1/4～1/5 of the diameter of the inner drum.
The workpiece and sand entering the inner drum can quickly sieve the scattered sand at the inlet end. During the turnover of the casting, it not only rubs off the adhered particles, but also crushes and screens the unbroken particles. There is always a small amount of sand retained in the inner drum as a cushion layer for the workpiece, which solves the problem of collision and damage to thin-walled parts. On the entire length of the inner drum, the screened sand that enters between the inner and outer drums are guided by spiral blades and returns to the inlet end for discharging.
