Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In order to illustrate the technical scheme of the utility model, the following description is made by specific examples.

Only those parts relevant to the embodiments of the present utility model are shown for convenience of description.

Referring to fig. 1-3, the grinder comprises a machine table 1, a main shaft 2 is rotatably arranged on the machine table 1, two rotatable core wheels 3 are arranged on the main shaft 2, a plurality of mounting shafts 4 are rotatably arranged between the core wheels 3, a cylinder 5 is arranged on each mounting shaft 4, a rotating mechanism for driving the cylinder 5 to rotate is arranged on the machine table 1, a feeding port is arranged on the cylinder 5, a matched material door 6 is arranged on the feeding port, a mounting rod 7 is arranged on the back surface of the material door 6, locking mechanisms for locking the mounting rod 7 are arranged at two ends of the cylinder 5 and correspond to the feeding port, each locking mechanism comprises a claw seat 8, a pair of clamping blocks 9 are rotatably arranged at the claw seats 8, locking holes 10 are correspondingly arranged at the tail ends of the clamping blocks 9, and restoring forces are inwards arranged on the clamping blocks 9. For example, in the illustration, one of the clamping blocks is connected in the jaw seat 8 by a tension spring 11, and the other clamping block can also be connected by another tension spring. Or the torsion spring is arranged at the position of the rotating shaft of the clamping block to provide restoring force for the clamping block, which is within the protection scope of the embodiment. The material door 6 is provided with a pair of handles 12.

When the grinding test is carried out, firstly, materials are required to be put into a cylinder body, the cylinder body is internally provided with a grinding body, the cylinder body is made of steel plates, a steel lining plate is fixed with the cylinder body, the grinding body is generally made of steel balls, the grinding body is filled into the cylinder body according to different diameters and a certain proportion, and then, a material door is closed. The installation axle drives the barrel and carries out fast rotation, and when the barrel rotated, the grinding body is owing to inertia and centrifugal force effect, and the effect of frictional force makes it attach on the barrel welt and is taken away by the barrel, when being taken to certain height, because its own gravity effect is thrown down, and the grinding body that falls is like the projectile gives the material in the barrel and breaks up.

This device carries out the grinding test of material through setting up a plurality of barrels for can be simultaneously when same grinding machine grinds, multiple material of independent grinding, avoid being disturbed by other materials when grinding when increasing experimental fineness.
