Abstract

The invention discloses a feeding system for a viscous powdery material, belonging to the technical field of the industries, such as cementing, metallurgical mine and chemical engineering. The feeding system for the viscous powdery material, which is disclosed by the invention, is characterized in that a feeding articulated chute is arranged on the main body of a high-pressure roller mill; and an engineering plastic plate with ultra-high molecular weight is lined on the wall of the feeding articulated chute. According to the feeding system for the viscous powdery material, which is disclosed by the invention, the adhesion and blockage problems of the viscous powdery material in the aspects of materials, structures, external influence and the like are solved; continuous, steady, uniform and saturated feeding of the high-pressure roller mill can be ensured; and the good working prerequisite conditions of the high-pressure roller mill can be satisfied.

Description

technical field [0001] The invention relates to the grinding technology used in industries such as building materials, cement, metallurgy and mining, and chemical industry, and is particularly suitable for the feed system of roller presses and high-pressure roller mills for viscous powdery materials. Background technique [0002] With the development of grinding technology in recent years, roller presses and high-pressure roller mills based on the principle of material bed grinding have been widely used in the grinding fields of cement clinker, cement raw meal, slag, steel slag, iron ore, and chemical industry. Obvious energy-saving effect has been achieved (generally speaking, it is called a roller press in the building materials and cement industry; it is called a high-pressure roller mill in other industries such as metallurgy, mining, and chemical industry. The two are just different popular names in different industries, and the equipment itself has no Essential differe...
