Description

Broken fragments for coal cinder ball mill

Technical Field

The utility model relates to a cinder ball mill technical field especially relates to a cinder ball mill is with broken fragment.

Background

The coal slag is also called slag, one kind of industrial solid waste, along with the rapid development of the industry, the output of the coal slag is continuously increased, a large amount of coal slag is accumulated to seriously pollute the environment and influence the health of human bodies, the grinding is an important processing way of the coal slag, and the pulverized coal slag is used for manufacturing building materials, so that the resources can be saved, the environment can be improved, and the harm to the human bodies can be reduced.

The coal cinder ball mill is internally provided with a grinding body which is generally a steel ball and is mixed with coal cinder according to different diameters and a certain proportion and is loaded into the cylinder, when the ball mill cylinder rotates, the grinding body is taken away by the cylinder under the action of inertia and centrifugal force and friction force on a lining plate of the cylinder nearby, when the grinding body is taken to a certain height, the grinding body is thrown off under the action of gravity of the grinding body, and the falling grinding body breaks materials in the cylinder like a projectile. Because the surface of the steel ball is smooth and has small friction force, the friction force between the coal slag and the surface of the steel ball is small after the steel ball is impacted with the coal slag, so that the crushing strength to the coal slag is small, the crushing efficiency is low, the granularity after crushing is larger, and the crushing time is longer.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Example one

Referring to the attached drawings 1-3, the broken fragments for the coal cinder ball mill comprise broken fragments 1, the broken fragments 1 are integrally of a cylindrical structure and comprise a first end face 11, a cylindrical face 12 and a second end face 13, and a plurality of crushing devices 2 are uniformly distributed on the cylindrical face 12 along the transverse direction and the longitudinal direction at intervals. During the use, put into the cinder ball mill with a plurality of these broken pieces together with the cinder in, under the effect of cinder ball mill with certain speed and positive and negative rotation, broken piece and cinder mixed striking smash the cinder into the cinder ash of required granularity size with the cinder striking gradually, and breaker 2 that broken piece surface set up can more effectually smash the cinder, has solved the shortcoming that adopts the steel ball grinding efficiency low in the present cinder ball mill, the cinder granularity is big.

Further, in order to effectively crush the large coal cinder by the crushing device 2, the crushing device 2 is composed of a rectangular block 21 arranged on the cylindrical surface 12 and a crushing part 22 arranged on the surface of the rectangular block 21, and the rectangular block 21 can effectively increase the height of the crushing part 22, so that the coal cinder can be crushed with a longer crushing depth, the crushing times are reduced, and the crushing efficiency is improved.

Further, in order to improve the effective crushing effect of the crushing portion 22, the whole crushing portion 22 is a conical structure which is outward along the surface of the rectangular block 21 and has crushing edges, and includes a first edge a, a second edge b, a third edge c and a fourth edge d, one end of each of the edges sequentially extends to the edge of the rectangular block 21, and the other end of each of the edges sequentially converges into a crushing point e. The crushing part 22 has the function of cracking and decomposing the crushed coal by collision at the crushing point e and has the effective function of cracking after the four edges are matched to be contacted with the coal cinder, so that the effect of cracking and crushing the coal cinder can be greatly improved.

Further in order to prevent the broken coal cinder from being clamped between the adjacent rectangular blocks 21, an arc-shaped surface 210 is arranged between the adjacent rectangular blocks 21 and is in transition connection, and the problem of coal cinder clamping can be effectively reduced by the arc-shaped surface 210.

Further, in order to increase the rotational kinetic energy of the crushing block body during crushing, the diameter of the first end surface 11 is larger than that of the second end surface 13, and the diameter of the cylindrical surface 12 is gradually reduced along the direction from the first end surface 11 to the second end surface 13, so that the weight of the crushed block 1 close to the first end surface 11 is larger than that close to the second end surface 13. When broken fragment 1 is according to the rotation of cinder ball mill, because the weight of first terminal surface 11 one end is big, when making broken fragment 1 descend, this end has downward kinetic energy all the time, cooperates the rotation effect of cinder ball mill itself again for broken fragment 1 has more rotation number and striking number of times, further improves the crushing effect to the cinder.

Example two

The difference from the first embodiment is that: referring to fig. 4, the lengths of the first edge a, the second edge b, the third edge c and the fourth edge d are different, so that the crushing surfaces 101 formed by the adjacent edges are different in length and different in vertical direction, and after the coal cinder is in impact contact with the different crushing surfaces, the returning route is irregular, the impact between the coal cinder and the coal cinder can be further increased, and the crushing efficiency is further improved.

The principle of the utility model is that: when the crushing device is used, a plurality of crushed blocks and coal cinder are put into the coal cinder ball mill together, the crushed blocks and the coal cinder are mixed and collided under the action of a certain speed and forward and reverse rotation of the coal cinder ball mill, the coal cinder is gradually collided and crushed into coal cinder ash with a required granularity, the crushing part 22 has the collision cracking decomposition effect of a crushing point e and has an effective cracking effect after being matched with four edges to be contacted with the coal cinder, the coal cinder cracking and crushing effect can be greatly improved, and the defects that the grinding efficiency is low and the coal cinder granularity is large due to the adoption of steel balls in the conventional coal cinder ball mill are overcome.
