Common problems and solutions in flotation process

图片
1. Flotation machine Poor flotation effect, high tail loss This situation may be the flotation machine material grinding fineness is not up to standard or flotation agent dosage problem.If the grinding fineness cannot reach the indicators, the grinding fineness should be appropriately increased, and the grinding section number can be increased. If the dosage of flotation reagents occurs, the flotation reagents should be tested to determine the dosage and indicators of flotation reagents. 2.Flotation machine flotation cell foam larger, surface reflective When the floatation cell appears larger foam, and the surface appears reflective phenomenon, the possible reason is the flotation agent added too much, at this time the operator should adjust the dosage of flotation agent, observe whether the flotation foam condition has improved. 3.The liquid level of the single flotation cell of the flotation machine is on the high side If the problem of high liquid level in a single flotation cell

Why is the output of ball mill grinding not up to standard

图片
Ball mill grinding output is not up to the standard reason It is a very common problem that the output of ball mill can not meet the design requirement. Under what circumstances will the output of ball mill fail to reach the standard? 1 unreasonable design of the length of each warehouse of the ball mill The improper length ratio of each storehouse of the ball mill results in the imbalance of the coarse and fine grinding ability of the ball mill, which leads to the phenomenon that the product is too large or too fine, and then affects the output. 2. Poor ventilation of the ball mill In the normal operation of the ball mill, due to the repeated impact and friction of the medium in the cylinder, the temperature in the mill increases continuously, resulting in the water vapor produced by the water-bearing material. If the ventilation effect of the ball mill is not good, and the water vapor cannot be discharged in time, the water vapor will stick to the lining plate and steel

how to choose Dry magnetic separator or wet magnetic separator

图片
how to choose Dry magnetic separator or wet magnetic separator Dry magnetic separator is the first equipment used for industrial weak magnetic separation , suitable for dry areas, can be divided into large, coarse particles of strong magnetic and relatively fine particles of weak magnetic ore, simple process flow. Dry magnetic separation has higher requirements for materials. The sorted materials must be dry and in independent free form, otherwise it will affect the magnetic separation effect.In addition, dry magnetic separation efficiency is mainly restricted by three factors: roller speed, baffle position and feed size. Wet magnetic separator is widely used in iron ore dressing plants. It can not only be used for separation, but also can replace the magnetic dewatering tank as the concentration equipment before filtration.The process is complex, and the separation must be carried out with water as the medium. The wet magnetic separator can save energy and reduce consumption, and ca

The rotate speed of the ball mill

图片
The rotate speed of the ball mill The rotate speed of the ball mill directly determines the motion state of the steel ball in the barrel and the effect of grinding operation. When the rotate speed is low, the height of the ball in the ball mill is small, and the gravity of the ball itself slides and rolls down from the top of the ball load, in a state of falling. At this time, the impact force of the ball is small, but the grinding effect is strong. The ore is mainly ground and crushed, and the grinding effect is not high. When the rotate speed is high, the ball is lifted high.After the ball rises to a certain height, it breaks away from the cylinder body and falls along the parabola trajectory.It has a great impact on the drop point, the ore is broken by impact, and the grinding efficiency is the highest. When the ball mill rotate speed exceeds a certain limit (the revolution is very high), the ball rotates with the cylinder and does not fall, in the centrifugal operation state.At t

Reasons and measures of the ball mill bearing high temperature

图片
Reasons and measures of the ball mill bearing high temperature ? There are many reasons that cause the temperature rise of ball mill bearing, which need to be analyzed and take appropriate measures. Reason 1: Poor lubrication of ball mill bearing According to statistics, bearing damage caused by poor lubrication accounts for 40%, mainly reflected in: 1. Too much or too little lubricating grease; 2. Lubricating oil pipe is blocked; 3. Improper selection of lubricating oil or impurities in lubricating oil; 4. Failing to add lubricating oil in time; Solutions: 1, according to the oil standard, control the amount of oil, not too much or too little; 2. Clear the blockage of lubricating oil tubing in time; 3. Select high-quality lubricating grease or lubricating oil recommended by the equipment manufacturer; 4. Oil the bearing box regularly according to work requirements; Reason 2: ball mill bearing wear Most ball mills operate in a wet environment. When some fine dust enters the bearing
