Abstract
The utility model provides an ore grinding medium of a two-section ball mill, belonging to the technical field of a grinding device. The ore grinding medium is composed of a plurality of cylindrical steel sections with the same structures. According to the ore grinding medium of the two-section ball mill provided by the utility model, the cylindrical steel sections are adopted, so that hit areas of the steel sections on materials are increased, hit forces are uniform, the over-grinding phenomenon of the ore grinding materials is reduced, the ore grinding fineness is stabilized, the ore grinding effect is improved, and the ore concentrate grade is increased and stabilized.
Description
Technical field
The utility model relates to a kind of lapping device, is specifically related to a kind of milling medium of ball mill.
Background technology
The milling medium of used two sections ball mills is steel ball in the ore crushing process, and is as shown in Figure 1, and-200 newly-increased order material contents are about 10% in the ore milling product after this ball mill is pulverized; Amplification is less, and-400 order materials account for about 80% in the middle of-200 newly-increased order materials, press the particle size distribution law analysis; The ratio of pulverizing ore particle excessively that exists in the material is higher; Cause the ball mill energy dissipation, and cause follow-up magnetic separator sorting result variation, influence product quality.
The utility model content
The purpose of the utility model provides a kind of milling medium of two sections ball mills, and it can alleviate the mistake crushing phenomenon of material, stablizes the material fineness.
To achieve these goals, the technical solution of the utility model is: a kind of milling medium of two sections ball mills, wherein said milling medium are the identical cylinder steel sections of several structures.
The milling medium of two sections ball mills of the utility model, wherein, said cylinder steel section diameter, length are respectively 35mm, 45mm.
After adopting such scheme; The milling medium of two sections ball mills of the utility model adopts the identical cylinder steel section of several structures; The steel section is balanced to the increase of strike area, the hitting dynamics of material, has alleviated the mistake crushing phenomenon of ore grinding material, stablizes mog; Improved grinding efficiency, improved and stablized concentrate grade.
Description of drawings
Fig. 1 is the structure chart of the milling medium of existing two sections ball mills;
Fig. 2 is the stereogram of the milling medium of two sections ball mills of the utility model.
Specify the milling medium of two sections ball mills of the utility model below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 2, the milling medium of two sections ball mills of the utility model is the identical steel sections 1 of a plurality of structures, and steel section 1 is the cylinder of diameter 35mm, length 45mm, and the quantity of steel section 1 is looked the size of ball mill and decided.
The milling medium of two sections ball mills of the utility model is three steel sections that structure is identical; Become the line contact by a contact between medium, increased the strike area of milling medium, simultaneously balanced hitting dynamics material; Alleviated the mistake crushing phenomenon of ore grinding material; Stablize mog, improved grinding efficiency, improve and stablized concentrate grade; Under the situation of parameter constants such as pack completeness, mill speed, the milling medium of two sections ball mills of the utility model is as shown in the table with the grinding efficiency contrast of transforming preceding steel ball milling medium:
The above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
Claims (2)
1. the milling medium of two sections ball mills is characterized in that: said milling medium is the identical cylinder steel section of several structures.
2. the milling medium of two sections ball mills as claimed in claim 1 is characterized in that: said cylinder steel section diameter, length are respectively 35mm, 45mm.
