Description

Technical Field

[0001] The utility model relates to the technical field of grinders, in particular to a three-roll grinder with a high-efficiency heat dissipation structure. Background Art

[0002] In the preparation process of liquid epoxy resin, a three-roll grinder is often used to grind it to homogenize the liquid epoxy resin. A grinder described in the patent with the existing patent announcement number CN218189855U, when grinding liquid epoxy resin, pour the liquid epoxy resin from the feed port. The inverted trapezoidal feed port is convenient for feeding and forms a flow limiter for the liquid epoxy resin; since the first guide plate and the second guide plate are both magnetic, they can absorb the metal debris carried in the liquid epoxy resin. After the grinding of the liquid epoxy resin is completed, the third guide plate guides the liquid epoxy resin to flow to the designated location; the liquid epoxy resin flows through the magnet rod, and the magnet rod absorbs the metal debris carried in the liquid epoxy resin to improve the quality of the production of liquid epoxy resin. When the magnet rod absorbs more metal debris, the magnet rod can be replaced. During the grinding process, the grinding roller rotates at high speed and rubs against another grinding roller to generate high temperature, which causes a large amount of heat to be generated in the grinding part, which can easily destroy the raw material components of the epoxy resin. Therefore, the grinding roller of the three-roll mill needs to be cooled.

[0003] Based on this, a three-roller mill with a high-efficiency heat dissipation structure is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
