4. Check the fasteners of the equipment such as the bolts of the classifier, the base bolts of all the equipment, there must be no looseness. Strictly check the loose parts such as the equipment transmission.
5. All parts that need to be covered should be covered, such as the safety inspection cover of the equipment, the cover of the screw conveyor, the cover of the trench, etc., should be checked one by one.
A fan generates the airflow through the milling system and ensures dust free operation by keeping the plant under negative pressure.
According to the working principle of the vertical mill, the vertical mill needs a series of preparations before it is officially started.
Anybody in this forum who have had some practicalextensiveexperience on Vertical Roller Mill being used for cement grinding We areplanning to put up a new cement grinding plant using Vertical RollerMill300-350 TPH and before implementing the project, we would like togather as much nbspinformation regarding the actual operation of this millduring cement grinding and the quality of the product in terms of thefinenessparticle size distribution and how does it compare with the product ofa ball mill relative to these parameters.
Cement grinding Vertical roller mills versus ball mills. 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.

Fresh feed is introduced to the mill at a controlled rate through the upper feed chute. Milling takes place between the rollers and the table as the material moves outwards. The depth of the material bed on the grinding table is adjustable in order to control the retention time in the grinding zone. The ground material is entrained in the air stream which enters through tangential air ports in the base of the mill and is carried upwards to the classifier for the separation by particle size.
Grinding Mill,High pressure grinding mill,High pressure In the main frame,a high pressure spring withan elasic force of 1000-1500 kg is fixed on the roller suspender.When the grinder mill is working, the roller will circumgyrate around the main shaft and squeeze the grinding ring strongly with a high pressure 1.2 degree than Raymond mill.
Grinding table is one of the main accessories of vertical roller mill, which is mainly composed of table body, lining plate, pressing block, retaining ring, scraper plate, wind ring, wind deflector and other components. The primary function of the grinding table is to support the material bed and transmit the force generated by the grinding roller to the lower reducer. It also transmits the torque of the reducer to the grinding area.
