Dry, is the kaolin sand material in the processing equipment of kaolin powder processing into small pieces of stone, and then put small stone into the kaolin powder mill processing into kaolin sand, kaolin sand and finally put into vibrating screen for screening, the need to pay attention to is the screening when the need for iron removal treatment of kaolin powder in the use of vibration sieve, the specific method is to use iron bar iron suction suction.

Water law, distinguish is the use of the force of the water of kaolin sand, kaolin sand material processing machinery will into kaolin powder processing into small pieces of stone, and then put small stone into the kaolin powder mill crushed kaolin sand, attention is needed in the rolling process or stopping water, by the force of the water to run well sand rushed to the sedimentation tank, sedimentation well in the barn after drying and then into the sieve screening, and dry sieving, water screen also needs iron removal treatment.

Unlike the dry production of kaolin powder, iron water production process to produce small amount of impurity content less kaolin powder processing equipment of water erosion after precipitation plus, so kaolin powder quality water to produce than many high dry, kaolin powder price is relatively high.
