Speaking of the accuracy of the installation and commissioning of the slag vertical roller mill is rarely known, and most of them think that it is okay to have more points. I don’t know, the “missing” of the installation will also have a “difference” effect on the slag vertical grinding! Then in the installation, our slag vertical grinding needs to pay attention to which small links, let's look at the introduction of SBM heavy machine!

The horizontal tolerance of the base plate of the reducer on the foundation support of the slag Vertical Roller Mill should be less than 0.2mm/m. The height error from the center of the column bearing housing hole to the foundation frame shall not be less than ±1 mm, and the distance error to the center of the slag vertical grinding base frame shall not exceed ±1 mm. The flanges of the connecting bridge and the grinding roller column are placed in a plane with a horizontal error of less than 2 mm. The center line of the lower body and the center line of the basic frame should be heavy, and the deviation is less than ±5mm. The center line of the reducer and the center line of the base frame should coincide. The deviation should be less than ±1mm. The center line formed by the grinding roller should coincide with the center line of the reducer, and the deviation should be less than ±3mm.

The center line of the slag vertical grinding roller should intersect the center line of the reducer, and the deviation should be less than ±3mm. The center line of the slag vertical roller mill and the center line of the foundation frame shall be less than ±5mm. The center line of the classifier should coincide with the center line of the reducer, and the deviation should be less than ±3mm. The vertical tolerance of the rotor shaft of the classifier should be less than 0.1mm/m. The coaxiality tolerance between the input shaft of the reducer and the output shaft of the main motor should be less than Ф0.1mm. The axial drive of the main motor output shaft should be less than ±1.5mm.

For safety requirements, the electrical enclosure on the vertical roller mill should be grounded reliably and the grounding resistance should not exceed 4W. All electrical appliances on the slag vertical roller mill should have rain protection measures. There should be a startup ringtone. Two or three “emergency stop buttons” should be set in a conspicuous and convenient position on the console and slag vertical roller mill. The safety system shall be provided with a safety relief valve: the noise sound pressure level during slag vertical grinding operation shall not exceed 90 dB (A). Each monitoring value should set the alarm value or set the alarm and trip value at the same time. Conductive and central conductive devices shall be provided during the grinding of the grinding disc and the grinding roller. The main drive is interlocked with the auxiliary drive. A protective cover should be provided between the reducer and the motor.

Through the introduction of the SBM heavy machine, do you have a deeper understanding of the installation and commissioning of the slag vertical roller mill? Of course, for the installation of such things, it is good to install by the slag vertical roller mill manufacturer, but as a user, SBM heavy machine It is recommended that you also observe it for future maintenance and maintenance!
