Abstract

The invention discloses a grinding aid for phosphate rock, which is characterized by being prepared by evenly mixing the raw materials in parts by weight: 60-80 parts of triethanolamine and 20-40 parts of polyacrylate in a mixing tank, wherein polyacrylate is sodium polyacrylate or potassium polyacrylate. In the process of grinding the phosphate rock, the grinding aid is added into the phosphate rock the weight of which is 0.05-0.2% of that of the given rock, so that the handling capacity of a phosphate rock grinding machine can be effectively improved by 15-30%, the fineness is improved, and the handling capacity of the grinding machine is improved. Thus, the grinding aid for the phosphate rock is remarkable in energy-saving and environment-friendly effects and has good market application prospect.

Description

technical field [0001] The invention belongs to the technical field of phosphate rock processing, and in particular relates to a phosphate rock grinding aid. Background technique [0002] Phosphate ore ball milling is a necessary process for phosphate ore processing. It uses mechanical methods to refine phosphate ore, which is a process of particle size change and mechanochemical change. When the phosphate rock collides with the steel ball medium and is crushed, the internal electric valence bond of the particles is cut off, thereby forming a charge unit and generating static electricity, and the fine particles are easy to re-condense into agglomerates or adsorb on the surface of the medium, so there will be The phenomenon of over-grinding or ball paste milling. Phosphate rock grinding aid is an additive with strong surface activity and dispersibility. It is easy to adsorb on the surface and gaps of the material, which can reduce the interfacial tension of the material, and...
