Key evaluation factors affecting the quality of mixing equipment

Zyzhan Guide: with the continuous development of Chinese industry, the development of hybrid system and hybrid equipment will be more and more powerful Mixing covers the whole industrial field, such as chemical industry, food, building materials, medicine, fertilizer The products we use every day have at least one mixing process in production Mixing refers to the physical mixing of two or more materials without any chemical change It includes self flow mixing and mechanical mixing Self flow mixing refers to the movement between materials and the uniform mixing after Zui through self friction; mechanical mixing refers to the uniform mixing of materials after Zui through mechanical force, and the general gas mixing is self flow mixing; three-dimensional mixing equipment mixing is the combination of self flow mixing and mechanical mixing; All the mixing in which the mixing container does not move is mechanical mixing The evaluation of mixing equipment is based on different physical quantities 1 Mixing uniformity: analyze the physical quantity of material mixing, and obtain it through probability theory The mixing uniformity is determined by the type of mixing equipment 2 Dead angle: refers to the physical phenomenon that materials cannot participate in mixing in the mixing container The dead angle percentage is the physical quantity to evaluate the manufacturing quality of the mixing equipment 3 Mixing time: the physical quantity to evaluate the mixing speed refers to the time from the beginning of mixing of different materials to the time when the mixing reaches the uniformity requirement The mixing time is determined by the type and model of mixing equipment Improve the air permeability of the mixture, increase the output of the sintering machine, and use the mixer to make pellets of the sintering mixture Effective measures to improve sinter quality and reduce sintering energy consumption The principle of making small balls with mixer is that the mixture rolls into balls in the mixer On the one hand, the mixture rolls into a ball in the mixer; on the other hand, the ball that has already become a ball will suffer from the rolling impact damage, rolling friction damage, throwing and falling damage in the mixer If the process parameters and lining design of the mixer are unreasonable, the mixture will not only roll but also slide and unload in the mixer The process of mixture sliding and unloading in the mixer can't make the ball, and it can destroy the small ball in the mixture The optimization design of the mixer focuses on how to extend the rolling distance of the mixture in the mixer and reduce the impact, friction, sliding and unloading of the mixture balls in the mixer The intensified pelletizing technology of mixer includes: 1 Optimization and transformation of technological parameters of mixer, such as rotation speed, inclination angle, filling rate, etc 2 Add nylon lining plate with pattern inside the mixer The main purpose of adding patterned nylon lining plate in the mixer is to improve the balling effect In the past, the mixer used lining plate with lifting plate On the one hand, it reduces the effective working diameter of the mixer, on the other hand, the lifting plate carries materials when it is working, which causes the mixture to drop in the mixer, which is unfavorable to pelletizing When the mixer is working, it will bring the sinter mixture to a certain height by this friction force, so that the mixture will form regular rolling in the mixer, which is very beneficial to the mixture pelletizing
