Stone separator

Conversion kit that removes unwanted stones from the straw

Conversion Kit

When straw is baled, it is difficult to avoid stones in the bales. These stones can result in unplanned stoppages of the  boiler system and an increase in the frequent cleaning of the combustion system. By installing this stone separator, you will experience an increase in the smoothness and safe operation of your straw fired boiler system.


The stone separator can be installed on plants where the straw is transported pneumatically.
