Abstract
The utility model belongs to the technical field of grinding mechanical appliances, in particular to a grinding body with the optimum shape used for a ball mill. The grinding body adopts the technical scheme as follows: the middle of the grinding body adopts a cylinder at two ends of which symmetrical hemispheres are arranged, the centers of the hemispheres are superposed with the center of circle on the end surface of the cylinder, and the hemispheres are tangent to the surface of the cylinder. The surface of the grinding body is smooth and free from ridges, and the optimum length-diameter ratio is defined as per the highest arithmetic product of the specific surface area and the intensity, so as to realize the strongest cooperation of the percussive action and the grinding function, improve the grinding efficiency of the mill, and reduce the steel waste.
Description
Technical field
The utility model belongs to the grinding machine equipment technical field, relates in particular to a kind of abrasive body that is used for the optimum shape of ball mill.
Background technology
Ball mill (Ball mill) or title tube mill (Tube mill) are the most frequently used a kind of milling equipments of industry such as cement, its groundwork partly is the single-revolution cylinder, pack in tube abrasive body (Grindingbody) or claim abrasive media (Grinding medium) and by the material of grinding, when cylindrical shell during with the revolution of certain rotating speed, then the abrasive body in the cylindrical shell to material execute a percussion and abrasive action with material pulverize, levigate.The utilization rate of this plant capacity is very low, generally between 2～9%.But ball mill is again indispensable milling equipment the industrial the present and the future that is applied in the quite a long time, so improve its mill efficiency, its energy consumption of the reduction of maximum possible is the major subjects of facing during ball mill is used.The shape of abrasive body is one of principal element that influences mill efficiency.In fact can trace back to the research of nineteen twenty-four D.H. Fan Er peculiar (Fairchild) about the shape research of abrasive body, at that time, he had done test to the abrasive media of cube and two kinds of shapes of spheroid in industrial mill.The result thinks that when feeding granularity was the same with Granularity Distribution, according to steel consumption and energy consumption, cube was better than spheroid grinding effect.The test of G.G.Jacox in 1980 thinks that the abrasive media of truncated cone-shaped is better than spheroid.The test of nineteen eighty-three D.U.Cloos thinks that but columniform abrasive media mill efficiency will be higher than spheroid.Nineteen eighty-three, China's Shoudu Iron and Steel Co mine company developed the kalimeris baseball, mainly contained two kinds of shapes, divided another name A type and Type B.Test thinks that the mill efficiency of kalimeris baseball also is higher than spheroid.
At present the abrasive body used of ball mill is in the majority with steel ball, also use cylindrical (being commonly called as the steel section), have also adopt in the middle of for column type, two ends are ball-cut shape, also have a kind of so-called Ding Shi abrasive body (cuboid deburring type), spheroid or the like.
Steel ball, when monomer mass was identical, in all geometries, the specific area of spheroid was minimum, and the specific area of abrasive body is big, and the chance that contacts with material is just many, and mill efficiency could be high.So little specific area is the greatest drawback of steel ball; The steel section is compared with steel ball, and it is big that its specific area is wanted, but its two ends are flat, and is but very little to the grinding effect of material; Have tangible crest line, effect is uneven to material grinding, and its draw ratio bigger serface more can be big more, but the reduction that will bring percussion, its pulverization also will reduce; Segment-segment type is compared with steel ball, and it is big that its specific area is wanted, and compares with steel ball, its two ends become the segment shape, increased the material grinding effect, but the same with the steel section, also have tangible crest line, effect is uneven to material grinding, and its draw ratio does not find optimum value yet.More than the shortcoming of all shapes cause its mill efficiency can not realize optimum efficiency.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of abrasive body of optimum shape is provided, the no crest line in surface, smooth, by the product maximum of specific area and intensity, determine best draw ratio, thereby realize that percussion and abrasive action synergy reach the strongest.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of abrasive body of optimum shape, and described abrasive body middle part is a cylinder, cylindrical two ends are the hemisphere of symmetry, the described hemispheroidal center of circle overlaps with the cylinder end face center of circle, and hemisphere and periphery are tangent.
Cylinder described in the utility model bottom surface diameter is 6～120mm.
The length overall of abrasive body described in the utility model with the ratio of cylinder bottom surface diameter is: 1.5-1.7.
The beneficial effects of the utility model are: a kind of abrasive body of optimum shape, and described abrasive body middle part is a cylinder, and cylindrical two ends are the hemisphere of symmetry, and the described hemispheroidal center of circle overlaps with the cylinder end face center of circle, and hemisphere and periphery are tangent.The surface of abrasive body does not have crest line, and is smooth everywhere, by the product maximum of specific area and intensity, determines best draw ratio.Thereby realize that percussion and abrasive action synergy reaches the strongest, mill grinding efficiency is improved, the steel consumption reduces.
