Economic and Gentle Pulverization of Spices

When grinding spices, low temperatures and gentle grinding are important to preserve volatile oils. With the Contra-Selector Mill, type PPS spices with a high oil content, sticky or moist and therefore tend to stick can be easily size-reduced in a single step. Due to the cool grinding process, without pre-grinding, losses in aroma are reduced to a minimum.

Decisive advantages

• One step grinding of whole product to desired fineness

• No loss in aroma due to pre-grinding

• Cool grinding due to short retention time of the spices in the mill 

• Flexibility, due to easy setting to desired particle size via screen, respectively speed

• Grinding of oily spices without additional cooling agents

• High throughput rate

• Safe operation due to self cleaning effect of the screens and by means of scrapers on the interior housing wall

Method of operation

The material is centrally fed into the Contra- Selector Mill via the material inlet. It is disintegrated and reduced by impact and shearing forces between the beater plates of the impeller and the counter or uni-directionally rotating screen basket.
