As one of the commonly used   mineral processing equipment , the quantity and proportion of steel balls in   ball mill   barrel not only affect the grinding efficiency and production capacity of ball mill, but also affect the ball mill’s service life. In the operation process, grinding efficiency of ball mill generally depends on the sum of the work done by each steel ball (the number of   steel ball   impact and the impact force produced by steel ball). Therefore, to give full play to the crushing efficiency of each steel ball, it is necessary to ensure that steel balls moving along different trajectories do not collide as much as possible. When the steel balls in ball mill barrel are too much, the steel balls will overlap with each other, so that part of the steel balls cannot rise to the required height and then fall down, unable to give full play to crushing ability. At the same time, it also increases the kinetic energy consumption and shortens the service life of the ball mi

In September, Xinhai successively appeared at EXPOSIBRAM 2019, International Industrial Trade Fair of Bogota 2019, MINEXP AFRICA 2019, EXTEMIN Perumin-34 Mining Convention, MinningworldCentralAsia-Kazcomak 2019 and Mining &Engineering Indonesia 2019 six international mining exhibitions with its   mineral processing EPC+M+O   service, which continuously enhanced its influence on the global mining industry. In the Xinhai exhibition area, the innovative mineral processing service mode, high brand awareness and on-site professional technical solutions attracted many domestic and foreign exhibitors to visit and negotiate. In the MINEXP AFRICA 2019, Xinhai successfully reached strategic cooperation intention with several new customers; In the MinningworldCentralAsia-Kazcomak 2019, the customers streamed in and out to consult; In the EXPOSIBRAM 2019, Xinhai met new customers and then went to the project site for investigation. Each wonderful and moving moment witnessed the highligh

The   spiral classifier   is one of the important mineral processing equipment, whose working principle is to classify the materials by using the difference in the settling speed of solid particles in the liquid. The classifying effect of the spiral classifier will directly affect the content of the qualified product in the returned sand, thus affecting the grinding efficiency of the   grinding mill . In the classifying process, the factors that affect the classifying effect of the spiral classifier mainly include the following three aspects: the feeding of the spiral classifier, the structure of the spiral classifier and the operation mode of the spiral classifier. Below, we will specifically analyze how these three factors affect the classifying effect of spiral classifier. 1. The feeding of the spiral classifier There are mainly two factors that affect the classifying effect of the spiral classifier in the aspect of feeding, one is the mud content of feeding, another is

When the   ball mill   works stably, the amount of material entering the ball mill is basically equal to the amount of material discharged from the ball mill. But sometimes, some reasons (such as the amount of returning sand increase, the amount of raw ore increase) will lead to the amount of material fed into the ball mill increased, which beyond the maximum capacity that ball mill allows, so that the material accumulates in the ball mill gradually and cannot be discharged, then lose its grinding effect. This phenomenon is called the overage grind of ball mill. But, do you know what the harm of overage grind is? What is the reason that led to the overage grind of ball mill? And how do we judge it timely and accurately? how to solve this problem? One. What the harm of overage grind is? The harm of overage grind mainly includes two aspects: 1. The problem of overage grind will make the ball mill reduce or even lose the grinding effect on the ore, and destroy the stable wo
