Raymond mill working process

The whole structure of Raymond Mill is composed of main machine, analysis machine, pipeline device and blower. It can be equipped with crusher, hoist, electromagnetic vibrating feeder and electric control motor according to user needs. After the material is pulverized to the required particle size, the material is sent to the storage hopper by the hoist, and then the material is uniformly and continuously fed into the main grinding chamber of the Raymond mill by the vibrating feeder, and the grinding roller is driven by the centrifugal force during the rotation. Swinging outward, pressing against the grinding ring, the blade shovels the material and sends it between the grinding roller and the grinding ring, which is crushed by the rolling of the grinding roller. The fine powder after grinding of the material is brought into the analysis machine for sorting with the circulating wind of the blower, and the finely coarse material falls back to the regrind, and the qualified fine powder enters the finished cyclone powder collector with the airflow, and is discharged through the powder discharging pipe. That is the finished product. In the grinding machine of Raymond Mill, there is a certain amount of moisture in the material to be ground, heat is generated during grinding, water vapor is evaporated, and the interface of each pipe of the machine is not tight. The outside air is sucked in, so that the circulating air pressure is increased, and the mill is guaranteed. Working under negative pressure, the increased air flow is discharged into the dust collector through the residual air duct, and is purified and discharged into the atmosphere.

Solution for failure of ultra-fine grinding components

Ultra-fine grinding is the same as other mechanical equipment. During the operation, some abnormal phenomena that cannot be avoided, as well as sudden failures, will affect the normal operation of the equipment under severe conditions. The solution to the most troublesome faults of the limestone milling motor is to check whether the power socket, plug and power cord are out of the oxygen and break. If not, the power supply can be plugged in. When the motor is energized, it will not be used. When the hand plucks the wheel and rotates, it can be concluded that one of the two starting capacitors of the machine has failed. The second common situation is: the power is not turned, the external force can be rotated, but a weak current is emitted in the motor, which is caused by a slight leakage of the starting capacitor. If the current is too loud, the motor will not start at all, and it is determined that the starting capacitor is short-circuited. In the absence of professional equipment, the capacitor can be removed first, and the two leads are respectively inserted into the zero and fire line jacks of the mains to charge the capacitor, and then the two leads are short-circuited and discharged. If the discharge spark can be emitted at this time and there is a loud “beep” sound, it means that theGrinding Equipment capacitor can be used; if the spark and the sound are weak, the capacity of the capacitor has dropped, so you need to replace it or add a small capacitor. . This method cannot be used if the capacitor has been damaged and short-circuited, and must be replaced with a new product of the same specification. Shisheng is a professional manufacturer of mining equipment. While paying attention to green and environmental protection, it also pays attention to the quality and efficiency of equipment. It is a hot equipment manufacturer in the mining equipment market.

Effect of operating factors on the efficiency of ultrafine grinding

The operational factors undoubtedly affect the efficiency of the grinding milling machine technology. For example, in closed-circuit grinding, when the ratio of returning sand is too large and exceeds the normal passing ability of the grinding machine, the phenomenon of “running rough” will appear in the grinding products. If the sand return ratio is too small or there is no sand return, it will easily cause over-grinding. If the load is too large, the phenomenon of “running rough” in the grinding products is serious, and if the load is insufficient, the crushing is severe. Therefore, it is required to give uniformity and stability to the ore during sanding. When the ore amount is given, the efficiency of the grinding technology will be improved. The grinding grain size of each section is determined to be unreasonable. It also affects the efficiency of grinding technology.
Grinding concentration has a great influence on the efficiency of grinding technology. Because the grinding concentration of grinding equipment such as centrifugal ultra-fine grinding machine directly affects the grinding time, the concentration is too large, the material flows slowly in the limestone milling, the grinding time increases, and it is easy to over-crush. In addition, in the high concentration of the slurry, the coarse particles are not easy to sink, and it is easy to flow away with the slurry, resulting in “running rough”. If the concentration of the slurry is too thin, the material flow rate will increase. When the grinding time is shortened, “running coarse” will also occur, and at the same time, large-density ore particles are easily deposited on the bottom layer of the slurry, which may cause over-grinding. Therefore, proper grinding concentration should be mastered during operation, which requires strict control of water consumption. Generally, the coarse grinding concentration is usually from 75% to 85%, and the fine grinding concentration is generally from 65% to 75%.

Where can the ultrafine grinding adjust the fineness of the powder?

The fineness of the powder generally has a network definition, and the fineness of the powder determines the performance of the ultrafine grinding equipment. Therefore, how to adjust the fineness of the china grinding mill and the fineness of the ultrafine grinding and the production related factors? Let’s take a superfine grinding as an example. From the point of view of the mill’s energy efficiency, if the special material for grinding requires ultra-fine grinding equipment with a certain degree of fineness, it needs some fine adjustment. The optimum grinding speed of each material is different, so there is no uniform formula to accurately calculate the linear velocity of the rotor at the material level that is the most suitable material for the crushed material.
In the process of ultra-fine grinding, the most troublesome problem is the poor grinding fineness. The grinding powder often cannot meet the standard, sometimes it can only be repeated again and again, how to quickly prepare to adjust the grinding fineness of the grinding machine. What about the powder? Our company has summarized several common methods for adjusting the fineness in grinding research.
Firstly, the super-fine grinding main motor adopts frequency conversion speed regulation, and the spindle speed of the feldspar grinding can be greatly adjusted, thereby changing the positive pressure of the rolling ring (centrifugal force) and finally changing the grinding effect. The grinding application further increases the output power of the main engine and fan motor after the meal is increased. The limit position of the roller swing is again restricted, the gap formed between the ultra-fine grinding roller and the ultra-fine grinding ring during operation, and the gap can be freely adjusted, which can significantly adjust the grinding strength and the particle size control. Finally, replace the technical parameters of the air delivery system, increase the flow fan, wind speed and air volume in the overhaul. According to the principle of air separation, the size of the air separation is proportional to the flow of the rotor.
