Base on the plentiful experience of producing and marketing of impact crusher, Birnith R&D institution designed the PFW series impact crusher. It is the newest style impact crusher and has been widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.
By absorbing the advanced technology from the world, we researched and designed PF series impact crusher. It can be used to deal with materials whose size below 500mm and whose compression strength less than 360Mpa. Thus, it is widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.
PEW series Jaw crusher features big crushing ratio, reliable operation, easy maintenance and low operating cost. It is the new generation product designed and produced by Birnith, basing on our 30 year’s crusher production experience and the latest design conception.
