Description

Solid wastewater mud grinding aid doping device

Technical Field

The utility model relates to the technical field of grinding aid doping equipment, in particular to a solid waste cement grinding aid doping device.

Background

Grinding aids are mainly used for reducing grinding resistance and preventing particle aggregation. The grinding aid is physically and chemically adsorbed on the surface of a material, the friction force and the adhesion force among particles are reduced, the electric load on the surfaces of the particles is neutralized, the fluidity of the grinding aid in a mill is enabled to be good, and therefore the working environment in the mill is improved, which is known as powder rheology. The grinding process is a process that mechanical stress intermittently acts on the material, and during the action, the original cracks of the ground material are expanded and extended, and new cracks are generated; during the break, the attractive force of the unsaturated bonds then re-heals the crack, and when the two forces tend to balance, the rate of increase of the fineness of the grind diminishes or even decreases. According to the theory of 'adsorption reduced hardness', the grinding aid has dispersion depolymerization effect of preventing polymerization.

The grinding aid is required to be added in cement grinding, the conventional grinding aid adding device has single adding position to the grinding aid, so that the adding uniformity of the grinding aid is low, the grinding process of cement is not facilitated, the feeding speed cannot be adjusted by the grinding aid adding device, the situation that the adding amount of the grinding aid is too small or too much easily occurs, and inconvenience is caused to the grinding process of cement.
