Abstract

The invention discloses an air-flow vortex balling machine for producing spherical graphite, which consists of a machine body, a balling drive device and an internal classification machine drive device, wherein an internal classification machine, a powder balling module and a cooling system are arranged in the machine body. In the invention, an internal balling module and a classification module are rationally arranged, and thus, the air-flow vortex balling machine for producing the spherical graphite is provided. The air-flow vortex balling machine can ensure that the graphite powder undergoes the physical processes of thinning, shearing, collision, friction, coiling, uniting and densification in an air-flow vortex balling room or can realize the combination of a physical balling process and a mechanical powder thinning process to prepare the spherical product. The indexes, such as sphericity, grain fineness distribution, tap density, apparent density, actual density and special surface area, of the spherical graphite powder can be controlled in the range of pre-determined values; the quality is stable; the yield can be improved by over three times; and over 50 percent of energy consumption can be reduced.

Description

technical field

[0001] The invention relates to an airflow vortex spheroidizer, in particular to an airflow vortex spheroidizer specially used for producing spherical graphite. Background technique

[0002] At present, there are many crushing equipment used to produce ordinary graphite powder, and its varieties are relatively messy. However, equipment dedicated to the production of spherical graphite powder has not yet come out. In recent years, for the production of spherical graphite powder, individual production enterprises have modified the equipment for producing ordinary graphite powder, but the production effect is not good, and the products produced are far from meeting the requirements of spherical graphite, especially Indicators such as sphericity, particle size distribution range, tap density, bulk density, true density, and specific surface area cannot meet the technical requirements required by users, which restricts the application of spherical graphite in my co...
