Embodiment Construction

[0009] Referring to the accompanying drawings, it is a roller-type medium-speed mill. The working principle is that the grinding bowl and impeller device rotate clockwise under the drive of the reduction box. After the material falls into the grinding bowl from the central coal drop pipe, it is Moving radially outward, a material bed is formed on the grinding bowl, and the material bed passes under the rotating grinding roller device; at this time, the grinding force generated by the loading device is applied to the material through the rotating grinding roller , the material is ground into powder between the bowl liner and the grinding roller, and the material moving radially and circumferentially carries the crushed powder across the edge of the bowl and enters the conveying medium channel. The conveying medium is typically hot air , has three main functions: first, it provides the necessary power for the mill to separate the powder; second, the hot air continuously dries the...

Abstract

The present invention relates to a roller type mill with medium speed used for the electric power plant, metallurgy, chemical industry and cement powder making filed. The working principle is that: the milling bowl and the impeller device are rotated in a clockwise manner under the driving of the reducer, and the material falls to the milling bowl by the central falling coal tube, and then moves towards outside along the radial direction under the action of the centrifugal force, and a layer of material bed is formed on the milling bowl, and the material bed is through under the milling roller equipment which can rotate around the shaft. At this time, the milling force produced by the loading unit is pressed on the material by the rotating milling roller. The material is milled to the powder between the milling bowl liner and the milling roller. The material moving in a radial and surround manner carries the powder to pass the edge of the milling bowl to enter the transmission medium channel. The invention is of a novel and scientific design, which adopts hydraulic pressure turning to loading protecting the material with strong adaptability. The milling roller adopts the cone shaped roller shape, and using the special tool directly to turn the outside of the machine body for exchanging the milling roller sleeve, the milling roller bearing and the milling roller oil seal. Exchanging and overhauling the milling bowl liner is convenient, and the inner installing type coal powder separator structure is improved to the hopper shape, and the service life of the coal powder separator is prolonged, and the invention reduces the height of the milling machine and weight as well as the total investment of the project.

Description

Technical field: [0001] The invention relates to a roller-type medium-speed mill in the industries of power station, metallurgy, chemical industry and cement milling. Background technique: [0002] At present, there are several types of medium-speed coal mills at home and abroad, including MPS, ZGM, MPS-HP-II, RP, and HP types, among which MPS, ZGM, and MPS-HP-II type mills are all technically designed by German BABCOCK company Manufactured, the grinding roller is tire type, and the loading method is hydraulic loading; RP and HP type mills are designed and manufactured by the American ALSTOM company, the grinding roller is a tapered roller, the loading method is RP type hydraulic loading, and HP type is spring variable loading . MPS, ZGM, MPS-HP-II medium-speed coal mills have good adaptability to materials, but they are large in size, heavy maintenance workload, and high investment cost; RP and HP medium-speed coal mills are small in size and difficult to maintain. It is ...
