Description
Technical field
The present invention relates to the processing of the micro mist of calcium carbonate mineral, especially a kind of calcium carbonate fine powder process units.
Background technology
In mineral powder production process, existing technique is：Ore is successively by broken, storage, grinding, packaging production work
Sequence, and ore is in shattering process, generally use ball milling, jaw crusher or hammer crusher, but whether which is
Grain graininess after kind of crusher in crushing, it is all different, therefore when the ore particles after storage enter powder-grinding process,
The size of grain graininess can not ensure in a section, and ore particles be enter in milling equipment at random, therefore for
The production technology of same parameters, milling equipment grinds the powder particles come and is all different, to cause the quality of production of miberal powder
Cannot be guaranteed, and in discharging, it is also desirable to ensure the same area ore raw materials can discharging together, and ore particles
In powder-grinding process, material particles are progressively refined by equipment fine grinding, and specific surface area increases, and surface is due to chemical bond rupture
Charged, particle can mutually adsorb to form caking or sticky on abrasive body and liner plate, so that mill efficiency is declined, increase the energy
Consumption, to solve the above-mentioned problems, most of producers solve the problems, such as this in grinding process using grinding aid is added.And
Ore particles are in grinding, and to ensure that grinding machine vibratory output is small, grinding machine stable operation, bed of material stabilization is essential one
Part, the mode for stablizing the bed of material at present is sprayed water into Vertical Mill, increases the frictional force between material, to ensure to be formed on mill
The uniform bed of material reduces the vibration of grinding machine.However now in the actual production process, unilateral multiple spot water spray, water spray is uneven, can make
It is uneven at the material between mill and grinding roller, so as to cause the high vibration of grinding machine, the normal operation of equipment is influenced, and now
The more ejections of water spray are water columns, and water column, which will be formed the bed of material, wash away, its is made to generate pit, unstable so as to cause the bed of material, and
And the flow of water column has mobility, is easy so that bed of material part overly moist, influences mill and mill to material with grinding roller, make its powder
It grinds of low quality.
