Pulverizing device

Abstract

The invention discloses a pulverizing device. The pulverizing device is composed of a pulverizing main unit, a pipeline device, a transmission device and a motor. A fineness analyzer, a grinding roller assembly and a bag-type dust collector are arranged in the pulverizing main unit. A suction fan is arranged at one end of the pulverizing main unit. A suction pipeline is arranged at the other end of the pulverizing main unit. The suction pipeline is connected with a vibrating feeder. The suction fan is arranged on one side of the suction pipeline. The pipeline device is connected with the pulverizing main unit and composed of a cooling pipeline and a feeding pipeline. One end of the feeding pipeline is provided with an elevator and connected with the elevator. An electric appliance control cabinet is arranged on one side of the pulverizing main unit. By the adoption of the structure, under the same yield and same fineness conditions, system energy consumption of the pulverizing device is only one third that of an air-stream mill, and the high-pressure micro-grinding price is only one eighth that of the air-stream mill; the feeding granularity is large, and the average granularity of superfine powder discharged at a time can reach 6.5 micrometers; by the adoption of an overlap type multi-sealing grinding device, the sealing performance is good, and dust removal effect of high-pressure micro-grinding can completely reaches the national dust discharge standard.

Description

technical field [0001] The invention relates to a grinding equipment, in particular to a device for fully grinding cured pulverized paint. Background technique [0002] At present, powder coating is a kind of solid powder without solvent. The coating is made of special resin, pigment and filler, curing agent and other additives, mixed in a certain proportion, and then prepared by hot extrusion, crushing and sieving. It needs to be heated, baked, melted and solidified before use to form a flat and bright permanent coating film to achieve the purpose of decoration and anti-corrosion. After the powder is mixed, it becomes liquid by melting, and then air-dries the liquid at atmospheric temperature to become solid. shape, using a pulverizer to pulverize. After pulverization, most of them are pulverized by a pulverizer, and then transferred to the pulverizer. At present, the pulverizer is an automatic pulverizer.

Problems solved by technology

[0002] At present, powder coating is a kind of solid powder without solvent. The coating is made of special resin, pigment and filler, curing agent and other additives, mixed in a certain proportion, and then prepared by hot extrusion, crushing and sieving. It needs to be heated, baked, melted and solidified before use to form a flat and bright permanent coating film to achieve the purpose of decoration and anti-corrosion. After the powder is mixed, it becomes liquid by melting, and then air-dries the liquid at atmospheric temperature to become solid. shape, using a pulverizer to pulverize. After pulverization, most of them are pulverized by a pulverizer, and then transferred to the pulverizer. At present, the pulverizer is an automatic pulverizer. For ultrafine powder with a one-time average particle size of less than 6.5um, how to provide a kind of equipment with good crushing effect, high output, and stable output and fineness has become an urgent problem to be solved.
