Problems solved by technology

At the same time, due to the significant increase in the specific surface area and surface energy during the cement grinding process, the tendency of fine particles to agglomerate with each other is significantly enhanced. If certain measures are not taken, the grinding efficiency will decrease, and the power consumption per unit production will increase significantly.

Abstract

The invention belongs to a cement auxiliary and particularly relates to a cement grinding aid and a using method thereof. The cement grinding aid is prepared from the following components in parts by weight: 0.5-5 parts of modified cellulose, 1-5 parts of polyether polyol, 2-10 parts of hydramine substances, 1-9 parts of an enhancer, 2-10 parts of polyhydric alcohol, 0.1-1 part of urea and 14-45 parts of water. The grinding aid for a cement processing process provided by the invention plays a role of adjusting the particle sizes of cement, enhances the cement strength and reduces the energy consumption in the cement production process.

Description

technical field [0001] The invention belongs to cement additives, in particular to a cement grinding aid, and also relates to its use method. Background technique [0002] In the ball milling process of cement production, when the particle size of cement particles is reduced to the micron level, the quality is in a uniform state, and the strength and hardness increase, resulting in deterioration of grindability. As we all know, the particle size of cement particles is between 3 and 32 μm Contributes greatly to the strength of cement, and the particle size of cement particles is 3~32 μm The more, the greater the cement strength. At the same time, due to the significant increase in specific surface area and surface energy during the cement grinding process, the tendency of fine particles to agglomerate with each other is significantly enhanced. If certain measures are not taken, the grinding efficiency will decrease, and the power consumption per unit production will increas...
