Abstract
The invention discloses the dry method ball mill of a kind of electrostatic dispersion, it is provided with high pressure powder charge device below ball mill bottom discharge mouth, high pressure powder charge device is connected with abrading cylinder, and powder granule returns abrading cylinder after discharging opening falls after high pressure powder charge device is charged.High pressure powder charge device includes electrostatic dispersion device staving, corona unit and adjustable high voltage power supply, and corona unit is positioned at electrostatic dispersion device staving and connects adjustable high voltage power supply.Electrostatic dispersion device staving upper end is connected with the discharging opening of ball mill, and lower end is provided with collecting bin, and collecting bin is connected with abrading cylinder by air delivery tube.Using the high-voltage corona discharge of 20KV～60KV, powder body is by electric field in dropping process, and powder surface falls into collecting bin after being applied in electric charge, then returns grinder by air delivery tube and continues to grind.Decreasing the reunion of granule, can make that material grinds is thinner；Power consumption can be greatly reduced.
Description
Technical field
The invention belongs to dry method ball mill, be specifically related to the dry method ball mill of a kind of electrostatic dispersion.
Background technology
Carry out in the crushing process of material using dry method ball mill, prolongation along with milling time, the granularity of powder body tapers into, the trend of the cohesive mass of fine powder is also gradually increased, and after the regular hour pulverizes, Jet Crushing is in the dynamic equilibrium pulverized and reunite, in this state, the pulverizing of material tends to slow, and grinding efficiency declines to a great extent, until the thicker phenomenon of granularity even occurs in balance.
Summary of the invention
For the drawbacks described above overcoming prior art to exist, it is an object of the invention to, it is provided that the dry method ball mill of a kind of electrostatic dispersion, subtract less granular reunion.
The dry method ball mill of the electrostatic dispersion that the present invention provides, same sex electric charge according to coulomb repels each other, the principle that the charges of different polarity are attracting, the material ground in grinder is carried out charged, make the electric charge that powder granule surface is the most same, between granule, the repulsive force of same sex electric charge is more than intergranular Van der Waals force and liquid bridge power, just loses the condition of reunion, reach the scattered purpose of granule between microparticle.Being provided with high pressure powder charge device below ball mill bottom discharge mouth, high pressure powder charge device is connected with abrading cylinder, and powder granule returns abrading cylinder after discharging opening falls after high pressure powder charge device is charged.Described high pressure powder charge device includes electrostatic dispersion device staving, corona unit and adjustable high voltage power supply, and corona unit is positioned at electrostatic dispersion device staving and connects adjustable high voltage power supply.Described electrostatic dispersion device staving upper end is connected with the discharging opening of ball mill, and lower end is provided with collecting bin, and collecting bin is connected with abrading cylinder by air delivery tube, and air delivery tube is connected with source of the gas.Using the high-voltage corona discharge of 20KV～60KV, powder body is by electric field in dropping process, and powder surface falls into collecting bin after being applied in electric charge, then returns abrading cylinder by air delivery tube and continues to grind.
The dry method ball mill of electrostatic dispersion that the present invention provides, it has the beneficial effects that, decreases the reunion of granule, and can make that material grinds is thinner；Power consumption can be greatly reduced.
