When the steel ball in the ball mill is in the optimal ratio, the breaking probability of the coarse and fine grain grades and the effect of the field are all in between: the larger ratio and the smaller ratio. The coarse-level grinding effect is not as good as that of the big ball. The fine-level grinding effect is worse than the small ball.
However, this ball loading system has taken care of the coarse, medium and fine grades of minerals in a balanced manner, so that all grades of ore particles can be effectively ground, eliminating the need for certain grades of grinding stones to be strengthened, and other levels of towers and mines. The phenomenon of deterioration. Therefore, the grinding effect of the cone ball mill is often better. The product contains too much coarse and too fine grades. The yield is high according to the qualified particle size, and the difference in particle size of the product becomes smaller. The process is beneficial.
The effect of the size of the ball mill on the grinding efficiency can be reduced. When the ball diameter is accurate, the crushing force is inevitably accurate, which reduces the excessive crushing caused by excessive crushing force and reduces the excessive crushing. If the ball diameter is accurate, there will be no large ball, which will increase the number of balls in the wet ball mill. The amount of crushing events that can be generated by one crushing will increase, which will help to improve the grinding effect. At the same time, the dissociation characteristics of the product are good, which can meet the basic purpose of grinding, and is beneficial to the sorting process.
The exact ratio of the ball diameter of the ball mill has two meanings: firstly, for a certain size class of ore particles, the ball diameter of the steel ball that breaks it must be accurate, and then the ball ball ratio is optimal, that is, the ball ball content of a ball and it The content of the broken ore particles is basically the same. Therefore, it is very necessary to analyze the influence of the size of the ball mill on the grinding efficiency.
Suspension system is an important part of modern automobile, which has great influence on the ride comfort and handling stability of automobile.
As the guiding and force transmitting component of automobile suspension system, the control arm transfers various forces acting on the wheels to the vehicle body, and ensures that the wheels move according to a certain trajectory. The vehicle control arm connects the wheel and the vehicle body elastically through the ball hinge or bushing respectively. The automobile control arm (including the Bush and ball joint connected with it) should have enough rigidity, strength and service life.
