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...
