Abstract

The utility model discloses a drum ball mill for manufacture of a low-cost aluminum nitride ceramic substrate for an LED. The drum ball mill comprises a ball mill drum, a bearing a, a bearing b, bearing blocks, steel balls, a big gear ring, an electric motor, a pulley, a reducer, a ball mill support, a feeding pipe, a discharging port, a drive shaft and a pinion, wherein the electric motor is connected with the reducer through the pulley and transmits power to the pinion through the drive shaft; the pinion drives the big gear ring to rotate; and the ball mill drum is supported on the bearing blocks at two ends. The drum ball mill is characterized in that a bag-shaped filter net is arranged at the discharging port, and the drum ball mill further comprises lifting plates which are fixedly connected to the inner wall of the ball mill drum and uniformly distributed on the inner circumferential surface of the ball mill drum. The drum ball mill has the benefits as follows: with adoption of the design, in a rotating process of the drum ball mill for manufacture of the low-cost aluminum nitride ceramic substrate for the LED, the steel balls are lifted to a certain height by the lifting plates and then fall and strike block materials, and the potential energy of the steel balls can be increased by the design, so that the block materials are ground into powder materials quickly in shorter time, and the production efficiency is improved; and further, the discharging is more convenient due to the design of the bag-shaped filter net.

Description

A kind of low cost aluminium nitride ceramic substrate manufacture tumbling ball mill for LED
Technical field
The utility model relates to a kind of LED low cost aluminium nitride ceramic substrate manufacture tumbling ball mill, particularly relates to one lump material quick crashing is made to granular material, energy-efficient, and facilitates the roller milling machine of discharging.
Background technology
Existing LED uses tumbling ball mill by motor with the manufacture of low cost aluminium nitride ceramic substrate, belt pulley, reductor, power transmission shaft, pinion, bull gear, ball mill barrel, the charging mouth of pipe and the discharging mouth of pipe, the part composite constructions such as bearing spider form, abrasion-proof backing block is installed in ball mill barrel, and steel ball is housed, ball mill is arranged on immobilizing foundation, ball mill barrel rotation in the time producing, and drive material and steel ball in cylindrical shell to be rotated formation drop percussion movement, the liner plate being mounted in steel ball and material and cylindrical shell clashes into, and steel ball, lump material is made into granular material by material mutual percussion rubbing action in rotary barrel, the shortcoming of this structure is: in equipment operation process, the material in ball mill and steel ball can only, under the drive of rotary barrel active force, upwards be made after partial arc motion the percussion movement that work falls, percussion material and liner plate downwards in the bottom of rotary barrel, this mode, the potential energy that steel ball produces is less, and drop is less, grinds block material speed slow, time-consuming length, inefficiency.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and lump material quick crashing is made to granular material, energy-efficient roller milling machine.
In order to solve above technical problem, the technical solution of the utility model is: low cost aluminium nitride ceramic substrate manufacture tumbling ball mill for a kind of LED, comprises ball mill barrel, bearing a, bearing b, bearing block, steel ball, bull gear, motor, belt pulley, reductor, ball mill bearing, feed pipe, discharging opening, power transmission shaft, pinion; Described motor connects reductor by belt pulley, and power is passed to pinion by power transmission shaft, and described pinion drives bull gear to rotate, and described ball mill barrel props up the bearing block in two ends; Its innovative point is: described discharging opening place is provided with bag-shaped screen pack, also comprises lifting blade, and described lifting blade is fixedly connected on ball mill barrel inwall, and described lifting blade is distributed in ball mill barrel inner peripheral surface.
On this basis, described lifting blade and Rotational direction of ball mill angle are 30 °---90 °.
On this basis, described lifting blade and Rotational direction of ball mill angle are preferably 45 °.
On this basis, the size of described lifting blade is less than the half of ball mill barrel diameter.
On this basis, the net footpath of described bag-shaped screen pack is less than diameter of the steel ball.
The beneficial effects of the utility model are: use after above design, the utility model LED uses tumbling ball mill in rotary course with the manufacture of low cost aluminium nitride ceramic substrate, by lifting blade, steel ball is risen to certain altitude, then fall shock lump material, this design can increase the potential energy of steel ball, thereby within a short period of time, fast lump material is ground to form to powdery material, enhance productivity, in addition, the design of this bag-shaped screen pack, also makes discharging become convenient.
Brief description of the drawings
Fig. 1 is the utility model LED low cost aluminium nitride ceramic substrate manufacture tumbling ball mill structural representation.
Fig. 2 is the utility model LED low cost aluminium nitride ceramic substrate manufacture roller ball mill machine drum body cross section structure schematic diagram.
Detailed description of the invention
The utility model LED comprises ball mill barrel 1 with low cost aluminium nitride ceramic substrate manufacture tumbling ball mill, bearing a, bearing b, bearing block 2, steel ball 3, bull gear 4, motor 5, belt pulley 6, reductor 7, ball mill bearing 8, feed pipe 9, discharging opening 10, power transmission shaft 11, pinion 12;
Lump material quick crashing can be made to granular material in order to make the utility model LED low cost aluminium nitride ceramic substrate manufacture tumbling ball mill, possess energy-efficient and facilitate the function of discharging, the utility model LED has set up lifting blade 13 with low cost aluminium nitride ceramic substrate manufacture tumbling ball mill, bag-shaped screen pack 14;
As shown in Figure 1, the utility model LED uses tumbling ball mill by ball mill barrel 1 with the manufacture of low cost aluminium nitride ceramic substrate, bearing a, bearing b, bearing block 2, steel ball 3, bull gear 4, motor 5, belt pulley 6, reductor 7, ball mill bearing 8, feed pipe 9, discharging opening 10, power transmission shaft 11, pinion 12, lifting blade 13, bag-shaped screen pack 14 forms; Motor 5 connects reductor 7 by belt pulley 6, and power is passed to pinion 12 by power transmission shaft 11, and pinion 12 drives bull gear 4 to rotate, and 1 of ball mill barrel is in the bearing block 2 at two ends; Be provided with bag-shaped screen pack 14 at discharging opening 10 places, the net footpath of this bag-shaped screen pack 14 is less than the diameter of steel ball 3; The benefit of this structure is: in the time of discharging, can directly topple over, topple over granular material and can enter next process, and do not needed to carry out the screening to steel ball in granular material 3 again, simplify processing step, operating efficiency is provided.
