Abstract

A pipe gas flow crushing device is a section of pipe with a spray gun ring, wherein the two ends of the pipe are in sealed joint with fly ash gas flow pipes, the spray gun ring is provided with a plurality of nozzles, the periphery of the pipe is provided with an O-shaped annular pipe, an air compressor is connected and communicated with the O-shaped annular pipe through a compressed air pipe, the O-shaped annular pipe is communicated with the nozzles through radial branch pipes, and the nozzles spray ultra high speed gas flows into the pipes. The device remarkably saves energy, occupies extremely small floor area, and is high in fine powder amount, simplified in process, good in sealing and environment-protection performance, simple in structure, and low in investment and production cost.

Description

Technical field: [0001] The invention relates to a material crushing device, in particular to a pipeline airflow crushing device for fly ash. Background technique: [0002] The traditional fly ash crushing method is to use a ball mill to grind the fly ash. see Figure 4 The schematic diagram of the ball mill structure is shown. The main body of the ball mill is cylindrical, that is, a rotating cylinder with a diameter of 1 to 3 meters and a length of several meters to more than ten meters. It is hollow and placed horizontally on the bearing bush. When grinding, 50% of the cylinder cavity The space is filled with fly ash and wear-resistant metal balls (several tons to nearly a hundred tons), and an external high-power high-voltage motor is used to drive the cylinder to rotate at a low speed through a reduction box. The impact and the friction between each other realize the fine grinding of fly ash. Because the weight of the ball mill and the metal ball itself is very large,...
