10.5 ft x 14 ft marcy ball mill with 800hp ge synchronous motor, 1200rpm, 4160v, 60 cycle, starter included (5 kv air breaker style), no liners.
1.The quartz ball mill uses a grooved ring-shaped lining plate, which increases the contact surface of grinding balls and ore, strengthens the grinding effect, reduces energy consumption.
John greeve, managing director for mutiny, said the decision to purchase the ball mill from citic was made after an extensive review process which included independent analysis by renowned gold plant specialists gr engineering services.
The process of beneficiation production line is as follows: the mining ores are firstly crushed by the jaw crusher as preliminary crushing, and after being crushed into a reasonable fineness, the material will be delivered to the ball mill through hoist and vibrating feeder, the ball mill will do crushing, grinding on the raw material.Fine materials that are already crushed and grind by the ball mill enter into the next process: classifying.
There are many types of internal stress of the ball mill, such as impact, extrusion, shearing, grinding, etc.Some of the stress electric energy consumption is large and the pulverizing efficiency is not high.Studies have shown that when the compressive stress with high pulverization efficiency is selected as the main stress, since the pressure pulverization process conforms to the smashing law of the material layer, when the pressure is small, the free loose material is first sufficiently dense, and when the pressure is increased, the squeezing particles are mutually the stress is transmitted, and when the strength value of the particles is exceeded, the mineral particles are broken and a large number of microcracks are generated.Adjusting and strengthening the energy input for different material characteristics, and also restraining the action area of the stress, so that the material passes through the stress zone regularly, and the mechanical energy is effectively converted into the pulverization energy, so that the particle becomes a blank product with low porosity.Through the subsequent process, a product with qualified particle size is obtained, thereby achieving the goal of high production and energy saving.
the service planning took about 5 months.In this process, it was key to have partially participated in the previous upgrading of ball mill 1013, because we were able to learn and implement continuous improvement to our entire proposal.Therefore, we managed to be thorough and realistic, says cristian fadic, vice president of mining services south cone in metso.
Energy-saving rod millgrinds 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.The larger the diameter, the slower the rotation.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 ball mills usually operate at 65% to 75% of the critical speed.
In case of continuously operated ball mill, the material to be ground is fed from the left through a 60 degree cone and the product is discharged through a 30 degree cone to the right.As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down from near to the top of the shell.In doing so, the solid particles in between the balls are ground and reduced in size by impact.
Ball mills typically are loaded with iron, steel or ceramic balls, or combinations thereof, about the size of a baseball.The balls rotate within the housing of the mill, macerating/pulverizing the contents to a desired particle size.During this process the balls gradually wear down in size, and must be replaced on a continual basis in order to maintain efficiency.Heretofore feeding of the balls has been a manual job, which is both difficult and dangerous.
