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.

DETAIL
Users can effectively screen the sand cores and other impurities without purchasing other sand filtration systems.
2.More efficient cooling mechanism for sand and castings:
The sand blocks are crushed through low-temperature grinding blocks inside the drum, the dust on the surface of castings is
peeled off, and the heat and dust are removed by a powerful dust collection system, in this way, the ultimate first level
cooling effect for recovered sand and workpiece is achieved.
3.Powerful rolling and grinding method:
The grinding block can effectively clean the silicon dioxide dust eroded on the surface of castings, and continuously grind
at various angles to reduce the shot peening of sand washing by 60% -70% (reduced from 20-22 minutes to 5-8 minutes).
4.Excellent cost-effectiveness ratio
This drum is integrated with the functions of sand/casting separation, sand screening, casting cleaning, and casting cooling.
In addition to effectively reducing the power and shot peening consumption of the sand washer by 60% -70%, the excellent
design can reduce the operating and maintenance costs, including saving 40% of labor. In low cleaning requirements (such
as riser and runner), it can be directly returned to the furnace for production through this rolling-washing process.
