Under the premise of satisfying the ball mill steering requirements, the ball mill gear component life is prolonged by improving the spray point of the gear lubricant, and the cost of operation of the ball mill is very meaningful. In the rotary kiln coal pulverized gear, the oil lubrication method has been cleaned for more than a decade, and the tooth surface is clean and the tooth shape is intact. This improvement method is simple and easy to invest less.
The pinion of the ball mill is arranged in angle ψ and steering. The arrangement angle of the pinion is often about 20%, which corresponds to the gear pressure angle. At this time, the positive pressure P1 of the pinion is vertically upward, so that the drive shaft is spaced vertically downward pressure, and the coupling bolt and ground of the pinion bearing The work of the foot bolts is advantageous, and the operation is smooth. Since P1, vertical up, reduced the force of the main bearing of the mill transmission end, the wear of the main bearing shaft is reduced. (In addition, reducing the lateral area of \u200b\u200bthe mill is reduced, the basis of the drive bearing and the mill main bearing can facilitate replacement of the pinion.) If the ball mill steering is opposite to the illustration direction, the coupling bolt is loose and Break.
What extent to the slurry of the ball mill reach, the ball mill is suitable for operations? What is the impact of the slurry ratio and the viscosity of the ball mill? Please see the following analysis:
The specific gravity and viscosity of the slurry are complex. The viscosity of usually the viscosity of the slurry increases with its proportion. Key factors affecting the specific gravity and viscosity are the amount of water and the type of dielectric species and its participation. When the slurry specific gravity and viscosity are small, the floating force of the slurry is smaller, and the material is not easy to adhere to the outer surface of the ball stone, and the direct touch between the ball is easily formed. It is difficult to play the grinding and destruction effect of the material, which has fallen the ball mill and increases the grinding of the ball.The ratio of the proportion of the slurry increases, the floating force of the slurry is increased, and the material of the ball stone increases, and the abrasive effect of the material is enhanced, and the wear of the ball is lowered.
However, when the specific gravity and viscosity of the material is too large, the slurry adhesion is not easy to leave, the slurry and the ball stone are too large, the slurry adhesion is not easy to leave, slurry and balls Stone cannot attack the opposing grinding movement, causing the abrasive effect of the material, severe people form a ball stone between the stones and the ball and the ball, and the ball stone and the lining are directly touched, causing the ball stone break and lining. Damaged.Thus, the specific gravity of the slurry and the impact of the viscosity giant on the ball mills are great. Practice proves that the specific gravity of the slurry in the ball mill is controlled in the medium and high aluminum ball 1.83 ~ 1.90, the natural pebbles 1.75 ~ 1.83, the viscosity is 30 ~ 60 seconds, and its ball mill is high. And the slurry function is also good. It is not easy to deposit, and the glaze is stable when it is glazed.
