Longyi wet mill is large superfine grinding equipment developed by our company after improvements. It can crush materials into powders at level of 2000-6000 mesh or even finer through scientific grinding medium ratio, longyi wet mill works continuously by feeding materials from the base through pump, after which frequency conversion motor drives main shaft at stable speed to grind the ball and materials and generate high-energy movement among materials and medium ball, creating crash, shear and friction so as to meet best powder requirement. Longyi wet mill can operate independently for processing nonmetallic minerals including calcium carbonate, barite ,clay, gypsum and talc etc.
