Abstract
The invention relates to a beryllium coarse powder crushing device and a production method for beryllium coarse powder using same. The beryllium coarse powder crushing device comprises a disc mill, a gravity classifier and a cyclone classifier which are sequentially connected; the disc mill comprises a cone-shaped casing, a fixing disc and a moving disc; the fixing disc and the moving disc are arranged inside the cone-shaped casing. According to the beryllium coarse powder crushing device, the disc mill which is provided with the fixing disc and the moving disc is used, beryllium scraps or powders are milled into powder satisfying requirements due to high speed revolution of the moving disc, classification is performed sequentially through the gravity classifier and the cyclone classifier, finally coarse powder with the grain diameter of 30 to 10 microns is obtained, and pure beryllium powder is obtained through impact milling to be provided for beryllium materials of different sizes. The production method for the beryllium coarse powder using the beryllium coarse powder crushing device is simple in technology, short in period and enables 1 to 10 kg beryllium coarse powder to be obtained per hour.
Description
Technical field
The present invention relates to the nonferrous production technical field, particularly relate to a kind of breaker of beryllium meal and adopt this breaker to prepare the method for beryllium meal.
Background technology
The performance quality of beryllium powder is the key factor that the beryllium material is produced and processed.Due to the particularity (poisonous, firmly crisp) of beryllium, therefore very high to material and the sealing requirements of equipment.At present, market is not applicable to the equipment of beryllium material fragmentation.
Summary of the invention
The object of the present invention is to provide the breaker of the beryllium meal of a kind of applicable beryllium material fragmentation.
Another object of the present invention is to provide the method that adopts this breaker to prepare the beryllium meal.
The technical scheme adopted for achieving the above object is:
A kind of breaker of beryllium meal, is characterized in that comprising the disc grinder, gravity classification device and the cyclone classifier that are connected in turn, and wherein said disc grinder comprises conical shell and is arranged on price fixing and the Moving plate in conical shell.
On described disc grinder, cold water circulating system is installed.
The beryllium lining is installed on the inwall of described price fixing and Moving plate.
Be connected with cloth bag separator on described cyclone classifier.
A kind of breaker that adopts above-mentioned beryllium meal prepares the method for beryllium meal, its processing step is: at first the beryllium ingot is removed to oxide on surface, make the beryllium bits, then open cold water circulation system, air inlet system and disc grinder, reconcile circle mill abrasive dust speed, adopt the mode of vibrating feed to send in disc grinder in the beryllium bits, the powder that to roughly grind to particle diameter be 76～59 μ m, again adjust circle mill abrasive dust speed, then successively by after gravity classification device and cyclone classifier, obtaining finished product.
The above-mentioned thicker powder of separating through the gravity classification device turns back in disc grinder and again grinds.
The above-mentioned fine dust of separating through cyclone classifier is collected through cloth bag separator.
Above-mentioned round mill abrasive dust speed realizes by controlling size of current, wherein controls the front electric current of abrasive dust at 6～8A, and the abrasive dust after-current is at 8～12A.
The breaker of beryllium meal of the present invention adopts the disc grinder with price fixing and Moving plate, utilize the High Rotation Speed of Moving plate that beryllium bits or powder are ground to form to the powder met the demands, then carry out classification by gravity classification device and cyclone classifier successively, the corase meal that final acquisition particle diameter is 30～10 μ m, impact grinding is made the pure beryllium powder of different model subsequently, for different model beryllium material.
The method technique that the present invention prepares the beryllium meal is simple, and the cycle is short, per hour can prepare beryllium meal 1～10kg.
The accompanying drawing explanation
The structural representation sketch of the breaker that Fig. 1 is beryllium meal of the present invention.
The specific embodiment
The breaker of beryllium meal of the present invention, comprise the disc grinder 1, gravity classification device 2 and the cyclone classifier 3 that are connected in turn, wherein said disc grinder 1 comprises conical shell and is arranged on price fixing 5 and the Moving plate 6 in conical shell, the mill that price fixing 5 and Moving plate 6 are two equal sizes, price fixing 5 is weighed son again, Moving plate 6 claims again rotor, by carbide alloy, is made.Stator and rotor parallel aligned, beryllium bits or powder be by stator and rotor, at the High Rotation Speed of rotor, grinds to form the powder met the demands.The conical shell upper end is connected with air inlet system (being specially the air inlet of opening by the conical shell upper end connects), under wind-force one stable condition, by controlling size of current, controls abrasive dust speed.On disc grinder 1, cold water circulating system is installed, by the cold water circularly cooling, the disc grinder temperature is controlled in 30 ℃, oxidized because of the disc grinder excess Temperature to reduce the beryllium powder.On the price fixing of disc grinder 1 and Moving plate inwall, the beryllium lining is installed simultaneously, to reduce the pollution of device damage to the beryllium powder, controls the increase of Fe.
The preparation technology of beryllium meal is: at first that the beryllium ingot is (cylindrical, weigh 6～12KG) adopt the lathe that strips off the skin to remove oxide on surface, adopt again and mill the bits lathe beryllium ingot is made to beryllium bits (a<20mm, b<10mm, h<1.5mm), open cold water circulation system subsequently, open air inlet system, open disc grinder, reconcile the mill degree of tightness, controlling electric current is suitable at 6～8A, with oscillating feeder, the beryllium bits are sent in disc grinder, the powder that to roughly grind to particle diameter be 76～59 μ m, and then reconcile the mill degree of tightness, electric current is that 8～12A is best.Worn into the powder of meal, carry and pass through the gravity classification device with certain wind-force, thicker powder auto-returned disc grinder grinds again, fine powder continues to be carried and to enter cyclone classifier and carry out secondary grading by air-flow, the fine dust that leaves cyclone classifier enters bagroom 4, trapped by cyclone classifier the powder got off and entered finished product bin, be i.e. disc grinder finished product meal.Through repeatedly grinding, finally make the corase meal that particle diameter is 30～10 μ m.
During this time, cold water, by continuous cooling stator and rotor, is controlled at the disc grinder temperature in 30 ℃, oxidized because of the disc grinder excess Temperature to reduce the beryllium powder.
