The Capacity of Mica Powder Production

The capacity of cement will rise for 10-15% if added with mica, and will rise for 20-30% if added mica and slag. It will also increase corrosion stability.

When producing mica powder, it can take the method of jointly grinding or separately grinding. The feeding mica fineness should be around 0.08mm (200 mesh), much smaller than other material.

Jointly grinding is to send the raw… Continue

Blockage Or Wear Of Ultrafine Mill

Blockage of sieve holes generally causes the blockage of ultrafine mill sieve holes because the mud content and water content in the feed are high, which makes the material stick to the sieve holes and block the sieve holes. Solution: The screen holes should be cleaned first, and then the amount of water spray and the inclination of the screen surface should be adjusted… Continue

The Shaking Of The Ultrafine Mill

During repair welding, the weld should be along the longitudinal direction of the pipe beam, and no transverse weld is allowed, otherwise the pipe beam will be easier to use. Fracture from transverse weld.

Beam fracture The ultrafine mill is mostly due to the long working time at the critical frequency, and the relaxation of a large number of high-strength bolts that fasten the… Continue

Treatment Of Ultrafine Mill In Operation

The radial clearance of the bearing is too small, and the radial clearance of the ultrafine mill bearing is too small, which will cause the bearing to over-grind and heat up, mainly because the bearing has a large bearing capacity, a high frequency, and the load keeps changing.

Solution: It is recommended that the bearing adopts a large clearance. If it is a bearing with… Continue

Improper Operation Of Kaolin Mining Plant

During installation, the bolts should be loosened, and the welding seam of the side plate and the bottom rib plate connecting the foundation and the flange should be cut open, and the pre-tightening bolts on the joint surface should be processed according to the above operation, and then welded.

If the location and cause of the leak cannot be determined, or if the operation effect is not good, you can try to fill the sealant around the kaolin milling equipment on-line surface flow… Continue

During Routine Maintenance Of Grinding Mill

When the grinding mill leaves the factory, the head shaft of the scraper mechanism and the reducer are often installed together. When installing on site, the head shaft and the reducer mesher should be disassembled first, reconnected to the scraper shaft of each slot, and the scraper shaft should be checked.

If the rotation is not flexible, you can add an adjustment pad between the scraper bearing seat… Continue

Vertical Roller Mill Maintain Regularly

The partition board or grate seam is blocked by some sundries or debris. In severe cases, it is completely blocked, and the grate hole becomes smaller, which causes the vertical roller mill to be "full grinding". If the vertical roller mill is not maintained regularly or is in disrepair for a long time, the partition plate may be partially broken off or perforated, causing the steel balls to pass through the warehouse and reducing the… Continue

Lining Plate Of The Vertical Roller Mill

The water content of the grinding material is too high (usually 2.0%), and the ventilation in the cylinder is poor, so that the water vapor and fine materials generated during the grinding process cannot be taken out of the vertical roller mill in time.

It is too large and adheres to the surface of the steel ball and the lining plate of the vertical roller mill, which slows down the flow rate, makes the discharge of the… Continue

Check The Main Bearing Hydraulic Station

To check the oil quantity and cleanliness, the oil quantity and cleanliness can be checked through the oil flow indicator, the observation hole on the hollow journal bush cover, the oil level indicator in the fuel tank, etc.

In addition, if the parking time is long in winter, the three-way cock at the water inlet of the main bearing can be turned to the waterproof position, and the siphon action can be used to discharge the accumulated water in the spherical tile through the water… Continue

Mini Cement Plant Continue Production

The sliding shaft of the mini cement plant is worn for a long time and reaches a certain thickness, the spherical body of the mini cement plant and the tile lining are difficult to combine, and scratches will occur. In general, this kind of situation is mostly because the temperature of the clinker of the hollow shaft is too high, and the temperature of the outer surface of the hollow shaft is also high, which causes the lubricating oil to be too diluted, lose its viscosity, and it is difficult… Continue
