  • Ball Mills Or Vertical Roller Mills: Which Is Better For

    Vertical roller mills Vs ball mills has long been a raging debate in the cement industry In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball millsThe difference between vertical roller mill and ball mill The ball mill is generally composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head The cylinder body is provided with an abrasive body, the cylinder body is made of steel plate, and the steel lining plate is fixed with the cylinder body, and the grinding body is generally a steel ball, andThe difference between vertical roller mill and ball millBall mills and vertical roller mill use different forces to achieve the necessary size reduction of clinker and gypsum plus other materials In ball milling, the size of the material is progressively reduced through the impact and attrition forces on the feed material as the rotation of the mill causes the tumbling action of the grinding parison Grinding Principle of Ball Mill and Vertical
