The invention relates to an environment-friendly production process for high-purity
montmorillonite. The production process comprises the following steps: (1)
drying, soaking, dispersing and sieving a
bentonite raw material to obtain a crude solution of
montmorillonite; (2) performing
ultrasonic dispersion on the crude solution to obtain suspended
emulsion; (3) performing
cyclone separation on the suspended
emulsion to remove a material with the
relative density of more than 2.5g / cm<3>, sieving, standing, and removing water on the upper layer to obtain a material on the lower layer; (4) performing high temperature and
high pressure cooperative ultrasonic sterilization on the material on the lower layer to obtain a sterilized material; and (5) performing
centrifugal separation on the sterilized material, collecting a material with the
relative density of less than or equal to 2.5g / cm<3>,
drying,
grinding until the average grain
diameter of less than or equal to 45mu m, and sieving by using a 325-400-mesh
sieve to obtain the
montmorillonite. The environment-friendly production process ensures medication safety,
clinical effectiveness and controlled quality, the process is simple and environment-friendly, the production efficiency is high, the production cost is low, the product quality is high, and industrial montmorillonite production is easily realized; and high temperature,
high pressure and ultrasonic
waves are combined for sterilization to ensure safety, reliability and a good sterilization effect.
