 Nowadays, with the continuous development of social productivity, green energy saving has become the theme of today's society, and various equipment has been continuously improved to save energy and reduce expenditure, especially in the heavy industry industry. It's easy to say, but for mining, power consumption is a big problem. Therefore, in response to similar problems, we propose two improvements, one is the equipment itself, and the other is to improve the operation of the process. On the one hand, resource throttling of the ball mill is very important. First of all, when designing the ball mill , full consideration must be given to the accessories and devices to save power and reduce consumption. In the design of the ball mill, considering the purpose of energy saving and consumption reduction, a new type of transmission system is specially designed, and a planetary gear reducer is used for transmission, which changes the traditional transmission layout and greatly impro

 Corresponding proportioning of the ball mill, so that it can crush minerals to the greatest extent, and meet the requirements of mineral crushing and grinding. The quality of mineral crushing can directly affect the efficiency of milling, and ultimately affect the overflow output of the ball mill. The level of ball loading can directly affect the crushing effect. These parameters are mainly affected by the specifications of the ball mill , the internal structure of the ball mill, and the fineness of the product. The ball must have sufficient impact force so that the ball has sufficient crushing capacity to handle the material, which is directly related to the diameter of the steel ball. The number of impacts of loading the ball must be enough so that the ball can crush the material. The average ball diameter and filling rate are the main influencing factors. The amount of filling is fixed. In order to ensure sufficient impact force, the diameter of the sphere can be reduced and the nu

 In the flotation process , there are many processes that affect the flotation effect. There are not only non-adjustable factors of ore properties, but also adjustable factors such as pulp concentration, pulp temperature, pH, flotation time, grinding fineness, and reagents. Let's introduce them one by one below. Ore properties refer to the chemical composition, mineral composition, structure, structure and element occurrence state of the ore. The oxidation degree of the ore has a great influence on the flotation effect, because oxidation will change the original mineral structure and make the mineral composition It is more complicated, thus changing the physical and chemical properties, and at the same time, oxidation will change the pH of the pulp, which will affect the use of chemicals. There is a great relationship between pulp concentration and recovery rate. Generally speaking, there is a normal distribution between the slurry concentration and the recovery rate. Only when the

 The configuration of the grinding body of the ball mill will have a great influence on the output quality of the ball mill. If there is a gradation of the grinding body, then the conditions such as the load of the grinding body must be fully considered. The following briefly introduces the calculation method of the grinding body. The first condition is the filling rate of the abrasive body. So what is the filling rate of the abrasive body? The percentage of the filling volume of the grinding body compared to the effective volume is called the filling rate of the grinding body. Generally speaking, if the filling rate of the grinding body is too high or too low, the grinding efficiency of the mill will be too low. For the grinding body filling rate greater than 32%, you can use the formula to calculate: Φ0=113-126H/Di Since there are many influencing factors of the grinding body, it is necessary to find a better filling rate in the production and adjust the equilibrium state according t

 Mining method is the core of mining. It can be said that the choice of mining method determines the operation of the entire mining system. The selection of a correct and reasonable method of mining for a mine plays a decisive role in the future production and operation of the mine. Inferiority determines the mining efficiency, production scale, ore recovery rate, and ore quality of the mine. The method of mining is restricted by many factors, such as the geographical location of the ore body, the stability of the ore rock, the type of ore, the taste of the ore, and the depth of burial. Although the burial elements of mineral deposits vary widely, in general, some rules can be summarized for the selection of mining methods, which are mainly divided into the following four situations: 1. If the buried depth of the ore body is shallow, and the extension depth is also shallow, all deposits are mined in open pit. 2. If the buried depth of the ore body is very deep, underground mining is a

 Through the macro inspection and the onlooker inspection, it can be found that the liner of the ball mill will occasionally show loose casting, oxides, and a large number of massive unmelted carbides and needle-like carbides.     The ideal microstructure of high manganese molten steel after treatment is a single austenite, but due to the metallographic examination of the liner, there are a large number of unmelted massive carbides and precipitated needle-like carbides in the microstructure. This is because the heating temperature is too low during the water toughening treatment, or the holding time is too short, so that the carbides are not fully integrated into the austenite. In the subsequent quenching and cooling process, a large amount of precipitation may be due to insufficient cooling speed. Needle carbide. From the field investigation, the heating temperature of the heat treatment furnace will be lower than the temperature required by the process due to long-term neglect and ma

The hydrocyclone is a separation device that uses the principle of centrifugal sedimentation to separate or concentrate the slurry. Because of its simple structure, large workload, high separation efficiency, low cost, and low maintenance cost, it has been widely used in mineral processing, petroleum and chemical industries. The structure and size of the hydrocyclone are very important for separation. The diameter and underflow of the hydrocyclone are very important parameters that affect the working capacity and separation efficiency. For a larger cyclone diameter, the separation efficiency is low, but the working capacity is high. Therefore, if the separation efficiency of the large-diameter separator is satisfied, it is preferred. For solid-liquid hydrocyclones, increasing the underflow will increase the flow rate of the underflow. However, if the amount of underflow is too large, a large amount of water will flow out from the outlet of the underflow pipe, thus impairing the functi

Overflow https://clactononseaessex.uk are widely used in cement, mining and thermal power generation industries due to their simple operation and low maintenance costs. With the development of society, the ball mill has made great progress in overall performance. The ball mill electrical control system is the central system of the entire ball mill, used to control various operating techniques.   The control system mainly includes: (1) Control of temperature measurement of bearings and stator windings; Each mill has three temperature measurement points for the main bearing at the feed end, the main bearing at the discharge end and the stator winding of the main motor, and the pinion bearing and the main motor have two temperature measurement points. At the same time, the status value of each point can be displayed in real time on the man-machine interface connected to the PLC, and the alarm value and shutdown value of each measurement point can be given. (2) Control of the main bearing

Grinding operation is very important in the entire beneficiation process, the cost is also quite large, the investment is huge and the energy consumption is high, therefore, choosing a suitable mill is very important for the entire beneficiation plant. At present, ball mills and rod mills are widely used in concentrators. However, the difference in appearance between ball mills and rod mills is not very large, and it is not easy to distinguish. However, a careful comparison shows that the difference between the two is still very large. First of all, from the point of view of the name, the grinding medium of the ball mill is a steel ball, generally less than 100 mm in diameter, and the grinding medium of the rod mill is a steel rod, generally greater than 500 mm in length. The discharge methods of the two are also very different. The ball mill has two types of discharge methods: grid type and overflow type. Both have advantages and disadvantages. The rod mill has no grid plate, and mai

 Gravity separation is an older method of beneficiation, which uses different settling speeds of materials in the medium for separation. For placer gold mines, due to mechanical and weathering effects, the gold-bearing parent rock is gradually broken into granular objects such as cuttings. Under the action of external force, minerals with larger specific gravity are deposited on river beds, mountain slopes and other places to form Enriched. For the sorting of placer gold ore, re-election is a more direct and economical method, and the beneficiation process of re-election includes cracking, screening, dehydration, separation and other stages. Reselection methods include jig selection, shaker selection, chute selection, centrifugal selection and other processes. These gravity separation methods are mostly used in placer gold ore with monomer dissociation, and are rarely used alone. They are generally used in combination with other processes to recover gold ore more effectively. The follo

Frequent bolt breakage is a phenomenon that often occurs during the working process of the mill. The reason for bolt breakage is that the manufacturing size of the large ring gear does not match the original design, and the rigidity of the ring gear is insufficient, which will cause the running track to appear elliptical and the large ring gear The excuse bolt is subjected to a lot of shearing force and breaks. In order to strengthen the fastening capacity of the bolts, we will adopt larger grades and higher strength bolts to ensure its strength. When checking the broken bolts, it was found that the nuts of the broken bolts had a small or trace amount of polishing. It can be judged that the bolts were loosened first and then broken. If you can ensure that the bolts are not loose, or reduce the impact of the bolts, the problem may be solved. To prevent loosening, you can try positive and negative buckle bolts and nylon composite nuts. You can do the following: (1) Change the bolt str
