As a large-scale crushing equipment, the high-pressure roller mill is usually installed on site after the components are assembled in the workshop. The roller, as the main crushing component of the high-pressure roller mill, has stricter requirements in terms of assembly and installation. , The following briquetting machine manufacturers have sorted out the installation steps of the high-pressure roller mill rollers and roller sleeves for your reference.
Assembly of high pressure roller mill rollers
The assembly and installation of the high-pressure roller mill rollers are mainly divided into two stages. The first is to install the roller sleeve on the roller core in the workshop. Usually, the burner is hot-loaded. After the roller sleeve is hot-installed, it is installed after natural cooling. Bearings; the second stage is the overall transport of the rollers and the installation of the rollers on the equipment.
1. Roller sleeve installation steps
(1) Before assembling, measure the inner diameter of the roller sleeve and the outer diameter of the roller core. The inner diameter of the roller sleeve is checked with an inner diameter micrometer. The graduation value is 0.002mm. The outer diameter micrometer suitable for this roller core is 1000mm~ 1500mm, the division value is 0.01mm, the division value is too large, the equipment comes with a special tool for measuring the roll core, the measurement is divided into three parts: upper, middle and lower, and each part is divided into three points A, B, and C. The average value of the measured data is taken. The inner diameter of the roll sleeve is smaller than the outer diameter of the roll core by 0.2mm~0.5mm.
(2) Use kerosene to clean the anti-rust oil on the roller core, there should be no burrs on the roller core, then erect the roller core on the erected bracket, adjust the verticality of the roller core with a level ruler, and wipe a small amount of lubricating oil.
(3) Assemble the roller sleeve after the adjustment of the roller core. Before hoisting, wipe the heating interior with acetone, hoist it away from 10cm, adjust the levelness of the roller sleeve with a spirit level, and quickly set it on the roller core after the adjustment is qualified.
