What Should We Note When Operating the Ball Mill?


Ball mill is a kind of a very important grinding equipment in ore dressing equipment. However, Xinhai mineral processing expert in visit knows, many users were not very familiar with the operating methods of grinding mill, which led to a lot of unnecessary failures.

So, what should we note when operating the ball mill?

1.Output size

We can choose the output size according to the nature of the object in the grinding process. Do not change the output size when the ball mill is under the output state. Too small output size will increase the power consumption of grinding, and it is difficult to meet the design requirements; Too large output size will cause overloading, increase the electric current of the ball mill, and reduce the grinding efficiency, even endanger the safety of the grinding equipment.

2.Quantity of ball addition

During the operation of the ball mill, the weight and diameter of the steel ball are constantly reduced due to wear, so we need to regularly add new ball for the grinder. And we need to determine the quantity of ball addition according to wear rate of steel ball and the processing capacity of ore.

3.Nozzle size table

The diameter size of the nozzle can affect the concentration, water quantity that flows through the ball mill, system circulating ratio and so on. Therefore, the nozzle size is usually not adjusted in order to keep the ball mill running well.

4.Particle size of limestone

Generally, too large limestone particle size will cause the extra burden to the ball mill, and some super-large limestone particles are not easy to be crushed by the steel ball, which not only reduces the efficiency of the ball mill, but also increases the power consumption. Therefore, we should make sure that the particle size of limestone is below the designed particle size.

All the above points need our attention in the process of using a ball mill. Xinhai hopes that every customer understands clearly these key points so that the ball mill can play out its maximum performance.

Guide of Gold Processing Equipment

图片
  The gold ore has a high mining value, the gold processing technologies are more complex, and the gold processing equipment used is not the same. At present, the common gold processing technologies mainly include the cyanide leaching method, flotation method and gravity separation method. That is, through the crushing, screening, grinding and classification, the ore is sent to the various  gold processing equipment  (leaching agitation tank, flotation cell, gravity separator) for separation. The concentrate obtained by the cyanide leaching, gravity separation and flotation are smelted by the chemical methods, and the product is finally made into the finished gold. Below, we will mainly explain the gold processing equipment used in the different stages of gold processing. One. Gold processing equipment used in the cyanide leaching method Cyanide leaching is one of the main gold processing methods, which can be divided into agitation cyanide leaching and percolation cyanide leaching.

Common Problems and Solutions of Jigging Process

图片
  Jigging process  has the advantages of good separation effect, large processing capacity, wide separation granularity range, less investment, low production cost, simple process system, etc., so it is widely used in the  gravity separation  process. As an important equipment in the gravity separation process, the operation of jigger is directly related to the product quality and the economic benefits of the concentrator. In case of abnormal problems of jig, which may affect the normal work of the subsequent process flow, it should be dealt with in time. Therefore, it is very important to understand the common problems of the jigging process and how to deal with them. Here are some common problems of jig in the jigging process and their solutions. 1. The screen plate is loose or broken During the jigging process, if the screen plate bounces with the pulsating water, the screws of the screen plate are loosened or dropped. If a column of water appears at a certain part of the bed during

Seven Common Froth Flotation Processes and Their Applicable Conditions

图片
Froth flotation   process is a kind of mineral processing technology that uses the flotation reagents to separate the ore according to the physical and chemical properties of the surface of the ore. The froth flotation process is to grind the mineral to the floating requirement, adjust the pulp concentration and add the flotation reagents, then inflate the air to make the mineralized froth separate. What are the common froth flotation processes? Do you know the application condition of the froth flotation process? 1. Preferential froth flotation process The preferential froth flotation process refers to float a kind of mineral first and inhibit another kind of mineral when the polymetallic mineral contains two or more kinds of useful components, and then activate and float other kinds of mineral. This process that recycles the useful minerals in turn is the preferential froth flotation process. Applicable condition: Generally, the preferential froth flotation process is
