a pulverizer

Abstract

The invention belongs to the technical field of powder grinding equipment, and particularly discloses a powder grinding machine. A rack is provided with a machine case in which a vertical rotating shaft is arranged; a driving portion drives the rotating shaft to rotate; a screen plate is arranged on the upper portion of the machine case; the portion, located above the screen plate, of the rotatingshaft is provided with a smashing portion; the position, located below the screen plate, of the machine case is rotationally provided with a disk which is fixedly arranged outside the rotating shaftin a sleeving manner; the position, located below the disk, of the rotating disk is coaxially and rotationally connected with a conical first grinding roller; a fixed rod is connected between the first grinding roller and the inner wall of the machine case; the disk is rotationally connected with a plurality of second grinding rollers in the shape of an inverted cone in the circumferential direction, and the first grinding roller and the second grinding rollers are attached and close to each other; and the portion, located above the screen plate, of the machine case is provided with a feedingport, and the lower portion of the machine case is provided with a discharging port. The powder grinding machine is mainly used for powder grinding, and solves the problem that in the process of preparing powder coating, steps for grinding blocky raw materials are more, and consequently the machining efficiency is lowered.

Description

technical field

[0001] The invention belongs to the technical field of milling equipment, and specifically discloses a milling machine. Background technique

[0002] Powder coating is a formula material based on new materials, with pigments and fillers. It is a new type of decorative material that has developed rapidly in recent years. It has energy-saving, pollution-free, high-efficiency, high-performance, and environmental protection. As a solvent-free coating, it has high coating efficiency, good anti-corrosion performance, one-time film formation and convenient storage and transportation, and is increasingly popular. It has three categories: thermoplastic powder coatings (PE), thermosetting powder coatings, and architectural powder coatings.

[0003] Before preparing the powder coating, it is necessary to grind the bulk raw materials into powder, and then mix the powder with other raw materials in a certain proportion to prepare the powder coating. In the crushing proc...
