Ball mill machine with exactly scientificball mill specification

INTRODUCTION OF BALL MILL MACHINE-ball mill specification

• Ball mill machine is an efficient tool for grinding many materials into fine powder.
• It grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.
• The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill.
• If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.
• The point where the mill becomes a centrifuge is called the "Critical Speed", and laboratory ball mill usually operate at 65% to 75% of the critical speed.

HOW TO ADJUST THE PROPORTION OF MILL BALLS IN BALL MILL?

• Keep the ball capacity and proportion reasonable.The limestones are transfered into thick liquid under the force of hit,extruding and grinding by mill balls.It's difficult to reach the degree of finess cause of the shortage of ball capacity.
  
  
• We will monitoring the ball capacity by keeping watch on the current of main motor of ball mill.Balls are added once the current is down obviously.It indicated that mill balls with big diameter are usually added,so that the wear down balls will be reused as other models.Balls will be added after running for a period which are generally 3 months.
