This machine is suitable for mixing dry powder material and granular materials in pharmacy, chemical industry, food, fodder, pottery, metallurgy, etc.This machine is composed of tow asymmetric cylinder, materials will do vertical and horizontal direction flowing, the degree of homogeneity can achieve above 99%. It adopts manual feeding materials and full-enclosed disc valve materials discharge, which do not product powder. There is no mechanical compression and strong friction, so it can maintain the intact of granular materials. The mixing barrel is made of stainless steel, which do not pollute the materials. In addition, this machine is equipped with timing device that can control the mixing time.
