grinding mill dust collector of the choice of several factors to consider
In some minerals processing pulverizing process, considering the impact on the environment, the mill needs to be equipped with dust collector, how to choose a dust removal device in the production process?
1, according to the density of dust dispersion and type selection
Dust dispersion has great influence on the performance of the collector, the dust dispersion, due to the different operating conditions, also have differences. Therefore, when choosing a filter type, the priority is to understand exactly dust dispersion, such as particle size in more than 10 um more optional cyclone. In more than one micron particle size, it should choose electrostatic precipitator, bag filter, the specific choice, can according to the degree of dispersion and other requirements, refer to the table type commonly used filter and performance in preliminary choice; And then in accordance with the conditions and introduce other kinds of filter and performance to determine.
2, the influence of dust adhesion sex for selection
Dust dust and the adhesion mechanism of wall and large specific surface area and the moisture content of the relationship. Water content, the smaller the dust particle diameter d, the greater the specific surface area, the more its adhesion. In flour production line process, general will choose cyclone dust removal and bag dust removal. In the cyclone dust collector, dust adhesion due to centrifugal force on the wall, there is a risk of clogging; Attached for bag filter of dust filter bag pore jams easily, for electrostatic precipitator is easy to make the discharge electrode and dust collecting dust.
