A special grinding aid for Raymond mill

Abstract

The invention belongs to the technical field of cement admixtures, and especially relates-a special grinding aid for a Raymond mill. The special grinding aid is prepared from, by weight, 45-60 parts of hydramine, 10-20 parts of glycerol, 5-15 parts of diethylene glycol, 8-20 parts of lignosulfonate, 3-10 parts of phosphate, 2-9 parts of monododecyl phosphate and 3-10 parts of ethylene glycol monovinyl ether; and the hydramine is a mixture of diethanolisopropanolamine and ethanoldipropanolamine. When a Raymond mill mineral admixture is used, the special grinding aid for the Raymond mill is added to significantly improve the material fluidity, improve the grinding efficiency of the mill, increase the output per machine hour of the mill and reduce the electricity consumption in production; and the special grinding aid can improve the active index and the fluidity of mineral components in every age, and has a good compatibility with water reducers.

Description

technical field [0001] The invention belongs to the technical field of cement admixtures, in particular to a grinding aid specially used for Raymond mills. Background technique [0002] Raymond Mill, also known as Raymond Mill, High Pressure Suspension Roller Mill, is a widely used grinding equipment. In the grinding station, Raymond mill is a widely used grinding equipment. Raymond mill has stable performance, strong adaptability, and high cost performance. Specifically, the advantages of Raymond mill are as follows: [0003] 1) The entire Raymond Mill is a vertical structure, with a relatively small footprint, strong systematization, and strong complete sets. Whether it is from rough processing of raw materials, transportation, powder making, and final packaging, it can be self-contained. independent production system; [0004] 2) The electromagnetic vibrating feeder is used to feed evenly, easy to adjust, small in size, light in weight, and easy to maintain; [0005] ...

AI Technical Summary

Problems solved by technology

Some problems existing in traditional Raymond mills have been plaguing mineral processing enterprises and equipment manufacturers

[0008] 1) The crushing and grinding ability is low, and it can only occupy the lower-end powder application market;

[0009] 2) The mechanical failure rate is high, the power consumption is large, the noise is large, and the emission pollution is large;

[0010] 3) The efficiency of the system is low, the separation effect of the product collection system is not ideal, and a large amount of fine powder cannot be collected effectively, resulting in waste of power due to repeated circulation in the system;

[0011] 4) The air duct design of the bellows of the main engine is not scientific enough. The larger particles in the material entering the grinding area and the particles that will not be ground in time are often thrown into the bellows and gathered at the tail of the volute, and continue to extend forward, so that the air flow is gradually reduced, which is easy Cause traffic jams, no or less powder output, affecting output
