Abstract

The invention relates to a splitting type rotor for a powder concentrator and a manufacturing process thereof. The rotor comprises a cage type rotor body formed by upper and lower flanges and blades, and a rotor cone which is coaxial with the rotor body and is arranged inside the rotor body. The rotor is characterized in that the splitting type rotor is formed by abutting two semicircular rotors which are divided through an axis plane. The manufacturing process comprises the following steps of: (1) preparing materials; (2) establishing a horizontal worktable; (3) drawing outer edge lines of the upper and lower flanges on the worktable and marking a circle center; (4) splicing the upper and lower flanges; (5) mounting the rotor cone; (6) mounting a cone flange; (7) mounting the upper flange and the blades, and weighing and encoding the blades; mounting according to an encoding sequence; in all the steps, adjusting the roundness, the coaxiality and the levelness and controlling the dimensional tolerance; (8) adjusting the balance of an integrally-grouped rotor; and (9) detaching the balanced rotor into two semicircular rotors and packaging and strengthening. The splitting type rotor disclosed by the invention has the advantages of convenience for storage and transportation and reduction of operation cost; the rotor blades can be replaced online and the production efficiency and the economic benefit are improved.

Description

technical field [0001] The invention relates to a structural part of a powder separator and a manufacturing process thereof, in particular to a split rotor for a powder separator and a manufacturing process thereof. Background technique [0002] In industries involving material crushing and grinding, such as building materials, electric power, and coal processing, material powder selection equipment is an indispensable key equipment. Taking cement production in the building materials industry as an example, the particle size of materials after grinding must meet the requirements of calcination. Therefore, a classifier is required for classification, and the new compound particles generated after calcination also need to be pulverized and classified by a classifier to form products; in addition, coal used as fuel in many industries such as cement and electric power also requires pulverization. Grinding and grading. This shows the importance and large number of powder separat...
