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 tenThe 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 mill

Cement grinding Vertical roller mills versus ball mills

grinding of raw materials The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalentVertical roller mill adopts threedimensional structure,which needs less space,ball mill is just the oppositeAnd vertical roller mill is cheaper than ball mill,if you don't need high productivity,roller mill is a better choice I think this note,which called what is theBall Mill vs Vertical Roller Mill bulkonline
