Centrifugal crushers, centrifugal grinding mills

All the equipments of the centrifugal grinding complex operate under vacuum, which eliminates the release of dust into the working area. The control system is based on microprocessors, which allows to fully automate the grinding process. The contact parts of the mill are wear-resistant cast iron or other alloysthe warrantee period is 1 year.
