Because of  slag vertical roller mill’s working, the spindle spinning mill is one of the main wearing parts, so the precision of grinding ring directly affect its service life. Focus is to control deformation of ring radial runout and heat treated. Exacerbate radial and the inner radius of deformation on impact, vibration rollers, adding additional loads, thereby reducing slag vertical roller mill grinding roller and grinding ring life.

 

Slag vertical roller mill grinding roller pressure adjustment is made via an external spring, which must be based on the hardness of the material, size, water, feed size and the required degree of fineness of finished product to adjust the suitable spring pressure. While the gap between grinding roller and grinding ring are important parameters that affect yield, fine powder content directly. In General, the user processing of the material is relatively fixed, when the intervals between grinding roller and grinding ring should be based on feed-grain size to adjust the optimum clearance, clearance is too large or too small to affect output and fineness, they also increase slag vertical roller mill vibration. 

 

Slag vertical roller mill work after a certain period, due to the wear of the grinding roller and grinding ring, will gradually increase in the space between, you should make adjustments in a timely manner.

 

Slag grinding stress deformation when subject to external pressure, forming internal stress concentrations. When the stress reaches the axis to the destructive power of the particle at its weakest, particles first burst and smash at the weakest. Practice of slag mill laminated broken slag particles is the concept of grinding not only in between the particles and the grinding roller and grinding ring, but also occurs between particles and particles. Characterized by stress there is effective in grinding Chamber grinding stage area, forming high density of multiple layers of particles, enough of the grinding force on particles of slag, laminated breaking role into full play, and received high grinding rate.

 

Make sure slag vertical roller mill and classifier are oil lubricated. Which hosts the spindle and three roller parts are set in the external oil tank, all the bearings are immersed in lubricating oils, in order to achieve reliable lubrication and cooling. Users can watch the oil level of the tank, lubricated in a timely manner, as required
