Titanium pigment is a white pigment mainly composed of titanium dioxide. Due to its unique physical properties and chemical properties, it is an important white pigment and ceramic glaze. It is widely used in coatings, plastics, ink, paper and other fields. 

Due to its high whiteness and high hiding power, it has been widely used in cosmetics in recent years. The production line of titanium white powder mainly has broken system, powder grinding system, conveying system, etc. We will briefly introduce the vertical roller mill

, pulverized equipment and conveying equipment used in the titanium dioxide production line. 

Traditional processing - laurel grinding machine series Ramon mill is a more stable and reliable grinding equipment, which plays an important role in titanium powder grinding. The equipment is mainly used to grind the titanium white powder, and its grinding effect is good, the finished grain size is fine and uniform, the pass sieve rate is very high, the equipment is complete set, the production efficiency is high. 

Insufficient power of the vertical roller mill  will result in insufficient air volume, and the material will flow normally in the air duct, which will also cause material accumulation.

The material is transported along the bad air duct under the action of the blower. Therefore, the normal operation of the blower should be maintained. When the wind of the blower is too small to transmit the material, the rated power and voltage of the vertical roller mill should be maintained during the overhaul. In order to ensure a stable and lasting work of the equipment.

Starting sequence of Vertical roller mill is: first to lubricating oil pump of vertical roller mill, when the oil pressure reaches 1.5-2.0 kg/cm, it is allowed to start the vertical roller mill, and then start the classifier. When everything is OK, we bagin to feeding.

At last, when stop the vertical roller mill, first to stop the feeding machine. After the ore treatment is finished, stop the vertical roller mill motor, and finally stop the pump. Use the lifting device of the classifier to lift the spiral out of the sand surface, and then stop the classifier.

This is daily Operation and Maintenance of Ball Mill, if you have other queation about vertical roller mill, please connect with us.

The speed of the drum is 15-25 rpm. The steel ball in the working cylinder continuously impacts and extrudes the coal block, and grinds the coal block into ultrafine mill. Then the coal is dried by hot air into the drum and the ultrafine mill is sent out. 


After separation by the separator, the ultrafine mill with a certain size is sent into the ultrafine mill bin or directly into the ultrafine mill burner. Steel vertical mill is bulky, high power consumption and noisy, but it is suitable for grinding hard anthracite because of its wide range of adaptability and reliable operation. 


Medium-speed coal vertical roller mill The speed ranges from 50 to 300 rpm, and there are many kinds. Common mills are flat disk mill, bowl mill, E-type mill and roller mill. Their common feature is that the grinding parts are composed of two groups of relatively moving grinding bodies. Coal blocks are crushed between the surfaces of the two groups of grinding bodies. 

It will fall freely under the action of gravity, and the abrasive body will be crushed like the projectile. The cyclic movement of the rising and falling of the grinding body is recurrent. In addition, in the process of vertical roller mill, the grinding body also produces sliding and rolling, so the grinding body, the lining plate and the material will be lapping, so that the material is fine.

Due to the continuous feeding of new materials at the feed end, there is a material difference between the feed and the discharge end material, which can force the flow of material. And when the grinding body falls, the impact of the material produces axial thrust, which also forces the material to flow.

In addition, the movement of air in the mill also helps the material flow. Therefore, although the barrel of the mill is horizontally placed, the material can flow slowly from the feed end to the discharge end and finish the grinding operation.

Damage of powder feeding bearing in vertical roller mill


Causes: (1) Oil breakage or seal ring damage. (2) Long-term lack of maintenance and cleaning. Exclusion methods: (1) timely refueling in accordance with the stipulated time. (2) Clean regularly and replace oil seals.              


The main engine has high noise and vibration.


Reasons: (1) Small feed. The shovel knife is worn seriously, the material cannot be shoveled, and the anchor bolt is loose. (2) The deformation of the grinding ring is serious. Exclusion methods: (1) adjust the feeding quantity and replace the new spade. (2) Replacement of feed size. (3) Replacement of grinding rollers and rings.


Fan vibration


The causes are: (1) powder accumulation or wear imbalance on the blade. (2) The anchor bolt is loose. Removal methods: (1) Clean up powder accumulation or replace the blade. (2) Tighten the anchor bolt.


Heating of drive and analysis engine oil tank


Reasons: (1) The viscosity of the oil is high, the screw pump oil can not be beaten up, so that the upper bearing is short of oil. Exclusion methods: (1) Check whether the grade and viscosity of the oil are in conformity with the requirements. (2) Check the running direction of the analyzer.
