By using a cloth filter bag or a Conidur filter (optional accessory), at-
tached between the SR 300 and the collection receptacle, the air stream
generated by the rotor-beater as it turns will be deflected and routed
downward to the material discharge. In addition, it increases material
throughput and ensures the separation of the fines in the air stream. Fig.

 Slide the filter bag E over the flange, holding the clamping ring at an
angle.
 Tighten the clip E1.
 Mount the collection receptacle F.
 Tighten the clips F1.
If the receiver is installed without a filter bag then it will be necessary to
expect dust to be discharged from the feed hopper D; therefore never
use the SR 300 without the filter bag or Conidur filter being installed.
Feed the product to be pulverized
Maximum feed grain size should not exceed 15 mm.
To allow for batch-wise or continuous operation the SR 300 can be ret-
rofitted with a 30-liter plastic collection receptacle and a Model DR
100/75 feeder (optional accessories).
 Close and switch on the SR 300.
 Slowly pour product into the feeder hopper D. Fig. 9
A baffle incorporated into the feeder hopper D keeps product from be-
ing ejected from the unit. Fig. 9
Feed product slowly and continuously, and only with the SR 300 run-
ning.
Overly large product grains or excessive product volumes can force
the SR 300 to stop; mechanical components could be damaged.
!
During pulverization dust-like product can exit from the feeder hopper,
filter bag or Conidur filter. When dealing with products which are toxic
or otherwise harmful to health, utilize either an extractor hood or per-
sonal safety equipment.
Hazard due to inhaling dusts which are dangerous to health.
!
Some products form an explosive mix with air after pulverization. Check
the properties of the product being processed.
