Description

Technical Field

[0001] The present application relates to the field of ultrafine powder crushing and grinding, and in particular to a disc nest mill. Background Art

[0002] Disc Nest Grinding Machine is an efficient and reliable grinding tool, widely used in various industries. Grinding is a process of precision machining by cutting materials on the machining surface with abrasive grains. As an important grinding tool, the basic principle of Disc Nest Grinding Machine is to use abrasive grains to accelerate the rotation toward the workpiece surface and continuously cut materials in relative motion.

[0003] In the related art, the disc nest grinding machine usually consists of three main parts: a disc-shaped base, abrasive grains and a binder. The disc-shaped base is the support part for grinding, the abrasive grains are the granular materials used for cutting, and the binder is used to fix the abrasive grains on the base, the disc-shaped base is fixed in the corresponding position, and the corresponding grinding operation is performed.

[0004] With respect to the above-mentioned related technologies, the disc-shaped substrate is in direct contact with the abrasive particles, which causes rapid wear of the disc-shaped substrate, reduces the effect of grinding and cutting materials, and affects subsequent related operations. Utility Model Content

[0005] In order to reduce metal foreign matter in materials, the present application provides a disc nest mill.

[0006] This application provides a disc nest mill, which adopts the following technical solutions:

[0019] By adopting the above technical solution, YG8 is a tungsten-cobalt material with good wear resistance, which extends the service life of the first patch and the second patch, improves the overall service life of the device, reduces the use cost of the device, and prevents metal foreign matter in the grinding part from entering the material.

[0020] Optionally, the grinding portion is provided with a plurality of positioning holes.

[0021] By adopting the above technical solution, the setting of the positioning hole provides support for the installation of the positioning bolt. The positioning bolt can be passed through the positioning hole and the second patch, thereby fixing the position of the second patch, and then fixing the second patch to the grinding part to prevent the second patch from sliding.

[0022] Optionally, both ends of the first patch are equipped with a horizontal rod, a connecting bolt and an abutment plate, the horizontal rod is rotatably connected to the first patch, the connecting bolt is threadedly connected to the horizontal rod, and is rotatably connected to the abutment plate.

[0023] By adopting the above technical solution, the horizontal rod rotates along the first patch, thereby changing the position of the connecting bolt. The connecting bolt and the horizontal plate are threadedly connected. The operator rotates the connecting bolt so that the abutment plate can abut against the grinding part or the second patch, thereby completing the fixation of the position of the first patch and preventing the first patch from slipping off the grinding part.
