Abstract
The utility model provides a device which can roll or vibrate a ball mill in the condition of the nitrogen protection under a certain pressure is a solid powder crashing device. A ball mill with a liquid medium or a fluid energy mill with nitrogen protection is commonly used to produce Nd-Fe-B magnetic powder. The utility model is provided with a structure which can prevent oxidation of in the process of crushing the rough material, and has the advantages of easy fabrication, low cost and high efficiency.
Description
The utility model belongs to pressed powder disintegrating process device.
Ball milling is to pulverize the pressed powder of a certain size particle (coarse fodder) thinner.General N d-Fe-B coarse fodder was the material of 40 mesh sieves; becoming granularity through ball milling is 4 μ m; ball milling divides dry grinding; wet-milling also has vibratory milling and rolling ball milling; the Nd-Fe-B magnetic is adopted liquid medium protection rolling ball milling or airflow milling both at home and abroad at present, because the very easily oxidation of Nd-Fe-B magnetic will prevent its oxidation during ball milling; list of references: 1. rich neodymium mixed rare-earth-iron-boron sintered permanent magnet, select from " third generation rare earth permanent magnet " p27.The Luo Yang chief editor.
Want a large amount of consumable liquid media owing to adopt liquid medium protection ball milling; and to pass through transition behind the ball milling; oven dry magnetic etc.; long and the contaminated environment of technological process; magnetic is very easily oxidation also; in order to overcome above-mentioned shortcoming, the utility model provides a kind of inert gas and the anti-oxidation pressed powder device of nitrogen protection ball milling.
The inner chamber ［ 5 ］ of gas medium protection ball grinder is to be made by stainless steel; the purpose that the end is the garden arc is to make place, dead angle at the bottom of jar, the not long-pending angle of magnetic; improved grinding efficiency; the particle of magnetic is more even; outer wall ［ 6 ］ is with heat conduction red copper preferably; material such as brass or aluminium is made; exocoel ［ 6 ］ adopts silver soldering to connect with inner chamber ［ 5 ］ and forms water jacket; faucet ［ 4 ］ with valve is welded on the loam cake ［ 2 ］; be welded with valve ［ 1 ］ on the loam cake ［ 2 ］; ［ 7 ］; weld seam is withstand voltage, and loam cake ［ 2 ］ adopts vacuum rubber circle ［ 3 ］ to seal with the ball grinder sealing, during ball milling coarse fodder is put into jar and fills with protective atmosphere; temperature raises and makes the coarse fodder oxidation in the jar when preventing ball milling, fills in water jacket with the circulating water cooling and reaches anti-oxidation effect.
Advantage of the present utility model is that ball grinder processing is simple; cost is low; easy operating, grinding efficiency height, the inflation of its tool; pass to the circulating water structure; prevent by the oxidation of milling material, protect ball milling than the consumption of saving big quantity of fluid Jie with liquid medium, and fluid transition; the operation of oven dry, and protection environment.
Embodiment one (vibratory milling)
Ball grinder inner chamber ［ 5 ］ is made with stainless steel, diameter phi is 150mm, and outer wall ［ 6 ］ is manufactured with red copper, red copper wall thickness 5mm, delivery port ［ 4 ］ has valve, water jacket is through the 3kg water pressure test, and through the 2kg gas pressure test, loam cake ［ 2 ］ is made with stainless steel in jar, wall thickness 5mm, the air inlet gas outlet ［ 1 ］ that has 2 valves on the loam cake ［ 2 ］, bore 8mm, but jar interior nitrogen injection pressure 1～1.5kg/cm
2,
Embodiment two (rolling ball milling)
Ball grinder inner chamber ［ 5 ］ is made with stainless steel, diameter is φ 100mm, outer wall ［ 6 ］ is manufactured with red copper, red copper wall thickness 5mm, and delivery port ［ 4 ］ has valve, water jacket is through the 3kg water pressure test, make with stainless steel through 2kg gas pressure test loam cake ［ 2 ］ in jar, wall thickness 5mm, loam cake has advancing of 2 valves on ［ 2 ］, gas outlet ［ 1 ］ bore 8mm, but jar interior nitrogen injection pressure 1～1.5kg/cm
