Rock Grinder Roll

Stone Grinding Roll is used for vertical grinding, which can crush, dry, grind and classify stone materials.
It can grind block, granular and powdery raw materials into required powdery materials.
Due to its high production efficiency, it is now widely used in new dry process cement clinker production lines.

What approach did Malaysia Cement Factory choose for quick fixes?

Once the Stone Grinding Roll is worn out, the conventional repair method is to disassemble and repair welding and then machine it, which requires a long repair cycle and expensive repair costs.
Using composite material technology to repair the wear of the vertical White Cement Grinder Roll body, it is not necessary to disassemble the grinding roller, and the time for replacing the roller skin or adjusting the surface can be used.
After simple surface treatment, coating materials, installation and tightening of the roller skin, it can be started and run after natural curing, saving a lot of downtime and maintenance costs for enterprises.
The polymer composite material has excellent adhesion properties and balanced and reasonable compression and wear resistance, which can fully meet the operation requirements of the equipment. After comprehensive consideration, the enterprise decided to use polymer composite material technology to repair on site.

Application steps of the wear repair scheme of the vertical grinding roller body

1. Preparation
Prepare construction tools, repair materials and corresponding accessories to be replaced in place, and at the same time do a good job of fixing the roller body to prevent accidents caused by rotation.

2. Surface treatment
Use a sander to polish the surface to be repaired and clean with absolute ethanol to ensure that the surface is clean, dry and firm.

3. Apply mold release agent
Apply a thin layer of 803 mold release agent on the matching surface of the roller skin and dry it for later use.

4. Blending materials
Strictly according to the proportion of special materials for Fuchs blue vertical mills, until it is uniform and has no color difference.

5. Coating materials
Use a scraper to apply the material on the surface to be repaired, first apply a thin layer, and repeatedly scrape and press to ensure that the material is pressed into each micro-hole, and then apply the material layer by layer according to the wear condition of the roller body to meet the repair thickness requirements, and the coating will be applied. Smooth the surface of the layer.

6. Installation
Quickly install the roller skin and tighten the bolts according to the specified torque value.
