Abstract

The invention relates to a coal mill. The coal mill comprises a housing; the upper part of the housing is provided with a coal briquette entrance and a pulverized coal exit; one side of the coal briquette entrance is further provided with a hot air inlet; the middle part of the housing is provided with a maintenance door; the lower part in the housing is provided with an impact wheel assembly; theimpact wheel assembly includes a transmission shaft and a hammering device arranged on the transmission shaft; two ends of the transmission shaft both extend out of the housing; and one of the two ends of the transmission shaft is connected with a power plant. The coal mill has the beneficial effects that a working face is easy to switch after a coal milling component of the coal mill is worn; the service life of the coal milling component is long; the coal mill is more convenient to maintain, and long in service life; and produced pulverized coal has uniform quality.

Description

technical field [0001] The invention relates to the technical field of crushing equipment in thermal power plants, in particular to a coal pulverizer. Background technique [0002] In thermal power plants and other production plants that rely on coal to provide heat or power, coal pulverizers are widely used. Coal pulverizers are machines that break coal blocks and grind them into coal powder. Existing coal pulverizers are based on different working principles. There are mainly ball mills, roller mills, fan mills, etc. At present, these types of coal mills generally have problems such as difficult replacement of coal grinding parts after damage, difficult maintenance, complex structure, and low service life of equipment. It is urgent for those skilled in the art to develop new coal mills to solve these problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coal mill to solve the deficiencies of the prior ar...
