Abstract
A highly efficient medium-speeded bowl mill consists of an upper separator, a middle shell, an upper millstone, mill bowls, a lower millstone, a millstone drive device and a lower shell. The mill bowl is a hollow ball with the outer diameter longer than 400 mm but shorter than 1500 mm and the wall thickness longer than or equal to 100 mm but shorter than or equal to 200 mm, which helps enlarge the milled area, reduce the number of the mill bowls, save material for mill bowl production, reduce the load of the bowl mill to a support gear box, and reach the purpose of improving efficiency and output and extending the service of the mill bowl.
Description
Technical field
The utility model relates to a kind of ball mill that particles such as block raw coal can be ground to form the powdery thing, particularly a kind of race pulverizer.
Background technology
Race pulverizer is a kind of milling apparatus that electric power, metallurgy industry prepare coal dust that extensively applies to.As shown in Figure 1, existing race pulverizer generally is made up of top separator 1, central enclosure 2, upper millstone 3, abrading-ball 4, lower millstone 5, mill drive unit 6, lower case 7.As shown in Figure 2, abrading-ball 4 is arranged in the ring raceway of mill 5, and mill drive unit 6 drives lower millstone 5 and rotates, upper millstone 3 does not rotate, abrading-ball 4 rotates in upper and lower mill 3,5, thereby forms the abrasive areas between abrading-ball and the last lower millstone, realizes the grinding to particle.
At present, the abrading-ball of race pulverizer mostly is the medicine ball that common iron is made, its diameter is subjected to the restriction of weight, smaller, must adopt the mode of little raceway, many abrading-balls to grind, usually ball radius is 150 to 400 millimeters, and abrading-ball quantity is 8 to 15, shortcomings such as existing therefore that abrasive areas is little, effect is low, yield poorly, abrading-ball service life is short.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of efficient race pulverizer is provided.
The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of efficient race pulverizer, form by top separator, central enclosure, upper millstone, abrading-ball, lower millstone, mill drive unit, lower case, it is characterized in that described abrading-ball be external diameter greater than 400 millimeters and smaller or equal to 1500 millimeters, wall thickness more than or equal to 100 millimeters and smaller or equal to 200 millimeters hollow ball.
The beneficial effects of the utility model are as follows: the efficient race pulverizer of the utility model changes abrading-ball into large diameter hollow ball by the solid sphere of minor diameter, thereby enlarged abrasive areas, reduced abrading-ball quantity, reduced the abrading-ball gross weight, saved the abrading-ball manufactured materials, ball mill is reduced supporting the load of reduction box, reach the raising effect, improve output, prolong the abrading-ball purpose (abrading-ball can extend to 25000 hours by original 8000 hours service life) in service life.

The specific embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.But the utility model is not limited to given example.
As shown in figures 1 and 3, the efficient race pulverizer of the utility model is made up of top separator 1, central enclosure 2, upper millstone 3, abrading-ball 4, lower millstone 5, mill drive unit 6, lower case 7, it is characterized in that described abrading-ball 4 for external diameter greater than 400 millimeters and smaller or equal to 1500 millimeters, wall thickness more than or equal to 100 millimeters and smaller or equal to 200 millimeters hollow ball.
As shown in Figure 4, the efficient race pulverizer of the utility model adopts the large diameter hollow abrading-ball 4 and the lower millstone 5 of big raceway to dispose.Among the embodiment, the abrading-ball quantity of a table grinder is 5 to 8.
The hollow abrading-ball of the utility model ball mill can be pressed the designing requirement casting with rich chromium cast iron or alloy steel material.Provide three specific embodiments below:
