Abstract
The invention relates to a coal series kaolinite powder grinding aid, and belongs to the technical field of coal series kaolinite powder processing. The coal series kaolinite powder grinding aid is prepared from the following substances in parts by weight: 1-5 parts of mixed alcohol amine, 1-10 parts of stearic acid, 5-15 parts of aluminum sulfate, 5-20 parts of limestone powder and 10-50 parts of talcum powder. The coal series kaolinite powder grinding aid disclosed by the invention is compounded from a mining raw material and a common chemical raw material, and has the advantages of sufficiency in raw material supply, easiness for obtaining raw materials, low toxicity, no volatilization, simplicity for production and processing and low cost. A coal series kaolinite grinding production enterprise achieves the simplicity and convenience for operation by using the coal series kaolinite powder grinding aid. The coal series kaolinite powder grinding aid disclosed by the invention is stable in property and can achieve the effects of improving grinding efficiency and reducing energy consumption.
Description
Technical field
The present invention relates to a kind of Coaseries kaolin powder grinding aid, belong to Coaseries kaolin Powder Processing Technology in China field.
Background technology
Coaseries kaolin is appositional pattern kaolinite, is mainly distributed in China's producing coal region, can be used for building, coating, paint and papermaking paint field.All application of Coaseries kaolin all through processing, must become ultrafine powder, just can join in other materials, merge completely.Coaseries kaolin energy consumption in superfine pulverizing process is large and efficiency is low, adds some grinding aid then can significantly improve grinding efficiency, reduces power consume.Cement or slag grinding aid through research, are not directly used in Coaseries kaolin grinding by current domestic many Coaseries kaolin grinding enterprises.Grinding Coaseries kaolin and pulverizing cement, slag require different, during grinding Coaseries kaolin, will by Coaseries kaolin superfine pulverizing, particle diameter is below 10 μm, and under normal circumstances, cement, slag powders particle diameter are at 30 μm, so it is worthless for directly cement, slag grinding aid being used for Coaseries kaolin superfine pulverizing.
Summary of the invention
In order to overcome the problems referred to above of existence, the object of the invention is to provide one to reduce energy consumption, improve mill efficiency, the easy to use grinding aid being applicable to Coaseries kaolin.
To achieve these goals, the technical solution adopted in the present invention is: a kind of Coaseries kaolin powder grinding aid, and it is prepared from by mixing hydramine, stearic acid, Tai-Ace S 150, limestone powder and talcum powder; The parts by weight of each material are: mixed hydramine 1 ~ 5 part, stearic acid 1 ~ 10 part, 5 ~ 15 parts, Tai-Ace S 150, limestone powder 5 ~ 20 parts, talcum powder 10 ~ 50 parts.
The parts by weight of each material described are: mixed hydramine 1 ~ 3 part, stearic acid 1 ~ 5 part, 5 ~ 10 parts, Tai-Ace S 150, limestone powder 5 ~ 15 parts, talcum powder 25 ~ 50 parts.
Described mixed hydramine is one or both in Monoethanolamine MEA BASF and diethanolamine.
A kind of Coaseries kaolin powder grinding aid of the present invention adopts customary preparation methods, is mixed by above-mentioned substance, stir and obtain Coaseries kaolin powder grinding aid according to proportioning.
The using method of a kind of Coaseries kaolin powder grinding aid as above, its with the volume of Coaseries kaolin weight 0.3 ~ 0.7% add in grinding machine with Coaseries kaolin intergrinding, reach saving power consumption, improve the effect of mill efficiency.
The present invention compared with prior art has following advantages:
1, grinding aid of the present invention is composited by mining industry raw material and common industrial chemicals.Raw material ample supply and prompt delivery, are easy to get, and low toxicity is non-volatile, and process for processing is simple, with low cost;
2, Coaseries kaolin grinding manufacturing enterprise is easy to use, only needs a weighing balance, weigh after and Coaseries kaolin together add grinding machine grinding;
3, grinding aid stable performance of the present invention, can improve mill efficiency, reduce energy consumption.
