Horizontal shaft impact crushers. Horizontal shaft impact crushers, such as the New Holland, Andreas and MaxCap (which is a hybrid of the two) styles, are typically used for the primary size reduction of soft-to-medium hard materials. These types of impact crushers can handle slightly abrasive, dry or wet material that is not sticky.
