Ball mill installation and debugging matters needing attention

Ball mill is indispensable equipment in the concentrator, but also the whole concentrator construction is very key equipment, so it is very important to ensure the stable operation of the ball mill. But before the formal operation, ball mill debugging is a very important step, can not appear any point of deviation, otherwise it will lead to ball mill product granularity can not meet the requirements, even reduce the metal recovery rate. So how to carry out the ball mill debugging work? Ball mill debugging should confirm whether to meet the debugging conditions, empty running and load running, check the status of various aspects of the equipment and so on. 1, check whether the ball mill meets the following debugging conditions Is the ball mill equipment installed according to the drawings, to ensure that all parts of the equipment in the correct position. It is required to have a complete installation process record and acceptance; The strength of the equipment foundation concrete and the strength of the secondary grouting concrete should reach the strength grade of the design requirements; PLC control system, temperature meter and pressure gauge of ball mill can be put in reliably.

What are the operation skills and maintenance points of the shaker

Shaking table is one of the widely used gravity separation equipment. Shaker separation is high, the concentration ratio of the concentrate is very high. During the operation of the shaker, mineral separation is achieved by the combination of bed surface and transverse flow. In order to reduce failures and improve sorting efficiency, operators need to seriously understand the operation skills of the shaker, and maintenance. First, shaking table operation skills In the operation of the shaker, it is necessary to carefully observe the partition of the shaker surface and control the appropriate vertical and transverse slope of the bed surface. In addition, it is also necessary to consider the feeding size, feeding amount, feeding concentration, washing water, stroke and other factors in the separation process. Below we aim at the above several main factors, to carry on the simple explanation to the operation skill of the shaker. 1, shaker bed surface partition The bed surface is divided into fine area, middle area, tailing area and slime area. Under normal conditions, the width of the slime area is 0.9 ~ 1.4m. The ore flow in the tailing area should be stable without rapids or furrows, and the thickness of the ore layer should be suitable and covered by water. Tail mine can be controlled by adjusting feed concentration and feed trough sand hole. Middling area is the interval of middling area, which is controlled mainly by adjusting flushing water and transverse slope. The concentration area requires obvious zoning of various specific gravity minerals, and a stable and obvious boundary between the concentration area and the primary selection area should be formed. This area is controlled by adjusting the flushing water and the transverse slope. 2. Horizontal and longitudinal slope of the bed surface of the shaker In the installatio

Circular shaker common 5 problems and solutions

Vibrating screen is very important auxiliary equipment in mine production, once the failure will directly affect the normal operation of the production line. As a common type of shaker, circular shaker (also known as: circular shaker) in the daily operation of the common problems are what? When we encounter these problems, how do we solve them? This paper analyzes the causes of five common problems of circular shaker and puts forward countermeasures. A, circular vibrating screen shaft fracture In general, the circular vibrating screen is mainly driven by the motor with eccentric quality of the vibrator to produce vibration. In the vibration process, the shaft is the key component that drives the vibration of the circular vibrating screen, and receives a large force. Therefore, in practice, shaft fracture is a common fault. Once the shaft fracture problem occurs, the circular vibrating screen will immediately stop working, its maintenance is more complex, must be given high attention. Reasons and countermeasures: 1. Long time metal fatigue or poor shaft material The shaft of the circular vibrating screen is a kind of metal material, which is subjected to the synthetic torque of torque and repeated impact force for a long time in the process of use. Under the action of long-term impact moment, the material inside the shaft will gradually fatigue, and fracture phenomenon will occur when the fatigue limit is reached. In addition, there are great differences in the torsional strength of different materials, if the materia

Slurry pump seal failure or cavitation how to do

Slurry pump is mainly used to transport abrasive particles and viscous high concentration slurry in concentrator. After a long time of operation, most of the concentrator will more or less encounter a variety of slurry pump problems, not only affect the normal operation of the whole concentrator, but also damage the economic benefits of the concentrator. In daily operations, slurry pump prone to problems are seal failure and cavitation, if not timely found and timely control, will affect the normal operation of the pump. One, slurry pump seal failure At present, slurry pump commonly used shaft seal for packing seal and mechanical seal.

Causes and solutions of belt conveyor belt running deviation

Belt conveyor is a kind of material transport equipment commonly used in concentrator at present, in which belt as a load bearing and transport device plays an important role. In the process of mineral processing, belt deviation is a common problem of belt conveyor, that is, in operation, the belt center line deviates from the center line of the conveyor and tends to one side. Belt deviation problem said big can be big, said small can be small, light belt "point injury", affecting the normal production line of the selection factory, heavy belt and rack violent friction so that the belt softening or even burning fire, the consequences can not imagine! Below, take you to understand the main cause of belt conveyor belt deviation, and give the corresponding solution.

Five common problems and solutions of hydrocyclones

Hydrocyclone is a more effective fine particle classification equipment in current mineral processing equipment. In daily production, there are more or less some equipment failures of hydrocyclones. If they cannot be found and solved in time, it is likely to lead to the shutdown of hydrocyclones. So, what are the common failures of hydrocyclones in daily operation? How do we solve these problems when we encounter them? This paper analyzes the causes and countermeasures from five common faults. 1. The ore pressure fluctuates greatly In the process of production, ore feeding pressure will affect the hydrocyclone capacity and grading granularity. Generally, the ore feeding pressure of the hydrocyclone should be kept stable according to the required pressure, and large fluctuation should not occur, otherwise it will damage the performance of the equipment and affect its classification effect. The large fluctuation of the pressure to the ore is usually caused by the drop of the pump tank level or air drag caused by the pump to the ore shortage, or the blockage of impurities into the pump. If the hydraulic cyclone after a long time of operation occurs to the mine pressure drop is mainly caused by pump wear. Solutions: 1. If the mine pressure fluctuation is caused by the drop of the pump tank level, it can be adjusted by increasing the level, or closing one or two hydrocyclones, or reducing the pump speed; 2. If the pressure fluctuation caused by pump blockage or wear, the pump needs to be repaired. 2. The hydrocyclone is blocked The blockage of hydrocyclone can be judged mainly by observing whether the overflow and bottom flow discharge of hydrocyclone are smooth. When there are more coarse particles in the overflow, the flow of the overflow and bottom flow decreases or the bottom flow stops, and the sand is discharged in columnar form, it indicates that the hydrocyclone has been bloc
