In the figure: the grinding machine comprises a grinding cylinder 1, a grinding roller 2, a support 3, a pressure spring 4, a support leg 5, a filter box 6, a feed box 7, a base 8, a motor 9, a cylinder cover 11, a magnetic rod 61, a handle 62 and a gear 63.

Detailed Description

The utility model is further explained below with reference to the drawings.

The embodiment is a vibrating mill for experiments, including horizontally base 8, the grinding cylinder 1 of horizontal setting, rotate and establish grinding roller 2, rose box 6 and workbin 7 in grinding cylinder 1, rose box 6, workbin 7, grinding cylinder 1 and grinding roller 2 all adopt stainless steel, relatively wear-resisting, corrosion-resistant, and chemical properties is stable. The feed box 7 is placed on the base 1, and the filter box 6 is placed on the feed box 7 and communicated with the feed box 7; the bottom edge of the filter box 6 is provided with a magnetic strip which is connected with the material box 7 in a magnetic attraction way, so that the filter box is convenient to disassemble.

The left end and the right end of the grinding cylinder 1 are arranged on the bracket 3, the cylinder wall of the grinding cylinder 1 is provided with a cylinder cover 11 which can be opened and closed, as shown in figure 4, the grinding roller 2 is of an eccentric cam structure, and the minimum clearance between the grinding roller and the inner wall of the grinding cylinder 1 is not more than 0.5 mm. The base 8 is provided with four legs 5 arranged in a square. The upper ends of the supporting legs 5 are respectively provided with a pressure spring 4, the lower end of the support 3 is correspondingly connected with the pressure springs 4, the thread pitch of the pressure springs 4 is small, and the supporting legs are not easy to deform in the axial direction. When the grinding roller 2 is driven to rotate by the motor 9, the gap between the grinding roller and the wall of the grinding barrel 1 is small, the material is extruded, the grinding barrel 1 can vibrate in a small amplitude under the action of the pressure spring 4, the material can move irregularly, the contact area between the material and the inner wall of the grinding barrel 1 and the grinding roller 2 is increased microscopically, the material can be ground in a limited space in the shortest time, and the efficiency is improved.
