Stepan Mysak, Тaras Voronchak Correction factor khum characterizes coal humidity increase over the value envisaged in mill design.Khum is determined by: m o a o d hum W W k where o Wd and o Wa – design and actual coal humidity, respectively, %; m – exponent characterizing the coal rank.Thus, when grinding the coal of ASH rank, m = 1, and in case of the coal of GHSSH rank m = 0.
The basic construction of a ball mill is a cylindrical container with journals at its axis.The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and the cylinder is put into rotation via an external drive causing the media to roll, slide and cascade.
The industry best in energy-efficient grinding, the OK Mill uses five to ten percent less power than other vertical roller mills and 30 to 50 percent less energy than conventional ball mills.Easy operation and maintenance.Worn roller grinding surfaces can either be replaced or re-welded inside the vertical roller mill.
The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium.The length of steel rod is 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% – 1%; the loading capacity of rod is about 35% – 45% of the effective volume .
This ball mill has two ways of grinding: The dry process and wet process.Ball Mill Features Ball mill is mainly composed of charging and discharging, cyclone and rotation parts.The ball mill is with stable and reliable working condition.
To ensure the stability of the mini ball mill, a ball mill base is design and fabricate to withstand the weight of the rotating jar, motor and gears.
