At the existing issue of above existence, main purpose of the present invention provides and a kind ofly can overcome the problems referred to above and further improve grinding efficiency and reduce to grind the Apparatus for () and method therefor of cost.
For achieving the above object, the invention provides a kind of to material pulverize milling apparatus, include: the grinding machine casing, feed inlet and outlet and the lid that is sealed into discharging opening, have a plurality of abrasive bodies in the grinding machine casing, make the power set that grind the casing action, inlet duct, air-out apparatus wherein are set on casing and/or lid, and the feeder that is connected with inlet duct.In airtight casing, provide pressed gas through inlet duct by feeder, can make grinding efficiency obtain very big raising.
On the other hand, under equal condition, the pressed gas of being imported is high more, and then grinding effect is better, but when the gas pressure in the casing was excessive, then the steadiness to casing exerted an influence, preferred in the present invention 0.1～50kg/cm
2
Certainly, can be casing commonly known in the art for the grinding machine casing, as the grinding machine casing of drum-type, the grinding machine casing of stirring-type or the grinding machine casing of oscillatory type, the pressed gas by feeder is imported can further improve grinding efficiency.
Therefore the present invention also provides a kind of Ginding process that material is pulverized in addition, grinding the lid that is provided with charging aperture and sealed feed inlet on the casing, have a plurality of abrasive bodies in the grinding machine casing, on grinding casing and/or lid, inlet duct and air-out apparatus are set, inlet duct links to each other with feeder, may further comprise the steps: by charging aperture material and abrasive body are joined in the grinding casing; The sealing lid; By feeder by inlet duct charged pressure gas in grinding casing; Grinding casing by the power set action grinds; Stopping to grind the back reduces by the air pressure that exhaust apparatus will grind in the casing; The lid of opening encapsulation is also discharged material.Can be implemented under the condition that does not need bigger cost cost by the method and to improve grinding efficiency.
Against existing technologies, the present invention has following useful effect:
1. the present invention adopts the method for inflation pressure grinding, the one, make medium (water or solution) pressurization after, the slabbing action of material is strengthened; The 2nd, the active force of pressurize airtight environment abrasive body and storeroom increases, and therefore grinding efficiency increases greatly.
2. milling apparatus of the present invention system highly versatile all can be used in all airtight grinding machines.Dry method, wet grinding, vibromill stirs mill and can use, and method is simple and practical, and is easy to operate, and productive rate is higher, steady quality.
