Problems solved by technology

Scholars at home and abroad have done a lot of research on the performance of final grinding cement, and found that due to its specific mechanical structure and grinding principle, the final grinding cement has different particle characteristics compared with traditional ball mill grinding cement. There is a significant difference. In the final grinding cement particles of the roller press, there are mostly flat and rod-shaped particles. This difference leads to a large water demand and shortened setting time of the final grinding cement of the roller press, which not only affects the cement's quality. Durability, and affect the normal use of cement

Abstract

The invention belongs to the field of particle shaping for cement particles, and particularly relates to a particle shaping method and particle shaping machine for cement particles. The particle shaping method for the cement particles comprises the following step that a shaping medium is added into a roller press, wherein the shaping medium is made of a material with the abrasion no more than 20g / t of cement. According to the particle shaping method and particle shaping machine for the cement particles, tabular and bar-shaped particles in the final ground cement of the roller press can be shaped into spherical particles.

Description

technical field [0001] The invention belongs to the field of particle shaping for cement particles, in particular to a particle shaping method and a particle shaping machine for cement particles. Background technique [0002] Roller presses are used for cement grinding, which can save energy by 20% to 50% compared with ordinary ball mill grinding systems. Because of their high energy-saving and production-increasing effects, they have been widely used in countries all over the world. The cement grinding process with roller press mainly includes: pre-grinding system, combined grinding system and final grinding system. Among all these processes with roller presses, the final grinding system of roller presses saves the most electricity and has the lowest operating costs. [0003] With the continuous development of cement grinding technology and the improvement of energy saving and emission reduction requirements, people are more and more aware that not only the grinding effici...
