Abstract
The utility model relates to a concave ball grinding body, which can be used as grinding medium used in ball grinders. A circular surface of the spherical cap-shaped grinding body is provided with a concave surface, the height of the concave surface is 55%-80% of the ball diameter, and the dent degree is 4%-15% of the ball diameter. The utility model has the advantages of proper rolling character, large grinding area, high grinding efficiency and electricity consumption saving, and the utility model is ideal grinding medium for thermal electricity, cement, ceramic ware and other industries.
Description
The utility model relates to the abrasive media that uses in a kind of ball mill.
At present, industries such as thermoelectricity, cement, ceramic are pulverized grinding to materials such as coal, green stone, ceramics, the abrasive media of using on original ball mill is made of round steel ball or cylindrical steel section, rod iron, they add man-hour in that material is carried out grinding, because ball, cylindrical abrasive media roll mutually, clash into, rub in circle roller ball grinding machine, it all is the dotted line contact that material between the abrasive body is carried out grinding processing, and the grinding acting surface is little, energy consumption is high, efficient is low.In order to increase milling area, Chinese patent CN1129147 " half-ball abrasive body " has appearred, it is characterized in that this abrasive body is that hemisphere by 1/2nd spheroid forms is constituted.Owing to have disk in this half-ball abrasive body, increased milling area, improved grinding efficiency to a certain extent, but the rollability of half-ball abrasive body has reduced, its rollability causes material attached on the abrasive body not as spheroid, forms " keeping " phenomenon, increase load so again, reduced grinding efficiency to a certain extent again.
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of rollability moderate recessed ball abrasive body, improves grinding efficiency.
The purpose of this utility model can realize like this: a kind of recessed ball abrasive body, it is characterized in that on the disk of ball crown type abrasive body concave panel being arranged, and the height of concave panel is the 55%-80% of bulb diameter, the depression degree is the 4%-15% of bulb diameter.The height of concave panel refers to the lowest concave of concave panel to grinding the peaked distance in spheroid edge, and the depression degree refers to the vertical range of the lowest concave of concave panel to disk.Rollability of the present utility model is spherical and hemispherical is moderate, and too big or too little rollability greatly influences grinding efficiency; On this recessed ball abrasive body concave panel is arranged simultaneously, both increased milling area, promptly strengthened the adaptability between the abrasive body again, reduce to rely on abrasive body to wear and tear automatically and produce the cycle of depression, improved grinding efficiency effectively.
Fig. 1 is a structural representation of the present utility model.
Further specify the utility model below in conjunction with embodiment.
Embodiment 1, a kind of recessed ball abrasive body, be to have concave panel on the disk of spherical abrasive body, the lowest concave of this concave panel is 65% of a bulb diameter to the height of the maximum at abrasive body edge distance that is concave panel, the lowest concave of this concave panel to the vertical range of disk promptly degree of depression be 10% of bulb diameter.The recessed ball abrasive body of this kind has the grinding efficiency height, the characteristics that operation energy consumption is low.With identical material ball, hemisphere, recessed ball abrasive body are done one relatively with identical ball mill below.
(specification 2.2M * 6.5M) closed circuit mill contrasts situation to the grog ball mill
Embodiment 2, reference example 1, and the concave panel height in the recessed ball abrasive body is 55% of a bulb diameter, the depression degree is 4% of a bulb diameter.
Embodiment 3, reference example 1, and the concave panel height in the recessed ball abrasive body is 80% of a bulb diameter, the depression degree is 15% of a bulb diameter.
Claims (2)
1. recessed ball abrasive body is characterized in that on the disk of ball crown type abrasive body concave panel being arranged, and the height of concave panel is the 55%-80% of bulb diameter, and the depression degree is the 4%-15% of bulb diameter.
2. recessed ball abrasive body according to claim 1, the height that it is characterized in that described concave panel is 65% of a bulb diameter, the depression degree is 10% of a bulb diameter.
