Problems solved by technology

[0004] Whether it is to produce phosphate fertilizer or to produce feed grade calcium phosphate, the grinding process is required. Most of the phosphate rock grinding adopts wet grinding. In order to ensure the fluidity and easy transportation of the pulp, the concentration of the grinding mass is generally about 30. -40%, when the weathering of phosphate rock is serious, or contains a lot of impurities and mud, the phosphate rock containing silicon and magnesium is more difficult to grind, and the grinding concentration will be lower, which means the grinding efficiency Lower, higher grinding costs

Abstract

The invention relates to a high-efficiency environment-friendly grinding aid for wet grinding of phosphate ore. The high-efficiency environment-friendly grinding aid is characterized by comprising the following components by weight percentage: 40-50% of auxiliaries, 10-20% of anionic dispersant, 5-20% of chelating agent and 10-30% of water; the sum of the percentages of all the components is 100%; and all the components are evenly mixed together to obtain the high-efficiency environment-friendly grinding aid for wet grinding of phosphate ore. The high-efficiency environment-friendly grinding aid for wet grinding of phosphate ore provided by the invention is a liquid at the normal temperature, and good in liquidity and low in dosage; generally, only 0.5-1 kg of high-efficiency environment-friendly grinding aid is needed for per ton of phosphate ore; the grinding aid is directly added to the front section of a ball mill through simple operation; and then the ore grinding efficiency can be improved and the ore grinding cost can be reduced.

Description

technical field [0001] The invention relates to a high-efficiency and environment-friendly grinding aid for wet grinding of phosphate rock. Background technique [0002] The ore crushing and grinding process is a process with high energy consumption and high cost. According to reports, energy consumption (in various industries in the world) for grinding operations accounts for about 5% of the world's total energy consumption, and energy consumption for crushing and grinding operations in ore processing accounts for this total energy consumption. 60% of. [0003] my country is rich in phosphate rock resources, ranking second in the world, and there are about 4.05 billion tons of phosphate rock with proven economic value. At present, 77% of the total output of phosphate rock in my country is used for processing and producing phosphate fertilizer, 16% is used for producing yellow phosphorus, and the remaining 7% is used for producing feed grade calcium phosphate. [0004] No...
