Grinding mill

There are many types of industrial grinding mill, the most commonly used, including Raymond Mill, ball mill, vertical roller mill, ultra-fine milling machine.

Vertical roller mill

Industrial vertical roller mill equipment model diverse, different functions, each have their own advantages, but the customer in the choice of time can not blindly according to the performance of the device to choose their own, should be based on the production of the project to select the appropriate equipment The Industrial vertical roller mill is mainly used to produce industrial demand for ultra-fine powder of a device, with the changes in market demand The device produced a lot of different models, these models in the function, size and other aspects of the nature There are some differences, these different differences to the customer's purchase caused confusion.

Although the type of industrial vertical roller mill variety, but in the choice of time or according to the actual needs of production projects, such as the size of the material, water and production requirements of the project to select the appropriate equipment.

Ultra - fine milling machine

Ultra-fine grinding of the entire structure is by the host, the analyzer (separator), pipe installation, blower, finished cyclone separator, jaw crusher, bucket hoist, electromagnetic vibration feeder, electric control motor and other components. One ultra-fine grinding host by the rack, into the volute volute, blade, roller, grinding ring, casing and motor components.

Ultra-fine grinding the whole process (grinding process): large pieces of material by the jaw crusher to the required size, the hopper will be sent to the storage hopper material, and then by the vibration feeder evenly and continuously sent Into the host grinding room for grinding, grinding powder after the fan airflow away. By the analysis machine for grading, in line with the fineness of the powder with the air through the pipeline into the whirlwind collector, the separation and collection, and then discharged by the powder tube is finished powder. The airflow is then blown into the blower by the upper end of the large cyclone collector. The entire airflow system of the unit is closed and circulated in positive and negative pressure conditions.

In the mill room due to the grinding material has a certain amount of water, grinding heat generated when the grinding chamber gas evaporation to change the air flow, and the whole pipe connection is not tight so that the outside of the gas was inhaled, so that the circulating air flow increases, resulting in milling Machine powder less or even explosive machine, which, the new European version of the ladder-type milling machine has been set in the upper part of the body with explosion-proof measures to maximize the explosion to avoid ultra-fine grinding machine brought accidental injury, at the same time, this The situation can also be achieved by adjusting the balance between the fan and the host to achieve the balance of airflow, and the excess gas into the small cyclone collector, the gas into the fine dust collected, and finally by the small whirlwind collector The upper exhaust pipe into the atmosphere, or into the dust collector to purify the exhaust gas, but the technical requirements of the operator is relatively high, and the need to detect and adjust Ultra-fine grinding machine work process is driven by the drive to drive the central axis of rotation, the top of the shaft connected to the plum frame, equipped with a roller set and the formation of swing fulcrum, roller around the grinding ring around the same time, the roller itself Due to friction and rotation. The lower part of the plum is equipped with a blade system, the position of which is in the lower end of the roller. The blade and the roller are fed into the grinding roller and the grinding ring between the grinding roller and the grinding ring. Roller rotation produces outward centrifugal force (ie, squeezing force) to crush the material, that is, to achieve the purpose of milling.

  • 1. The structure is simple and reasonable, self-attack broken, ultra-low use of the cost;
  • 2. Unique bearing installation with advanced spindle design, so that the machine has a heavy load and high-speed rotation characteristics.
  • 3. With crushing, coarse grinding function;
  • 4. High reliability, strict security devices to ensure equipment and personal safety;
  • 5. Smooth operation, work noise, energy efficient, high crushing efficiency;
  • 6. By the material moisture content of small, water content of up to 8%;
  • 7. Wear parts loss is low, all wearing parts are used at home and abroad high-quality wear-resistant materials, long service life A small amount of wearable parts made of special hard wear-resistant material, small size, light weight, easy to replace accessories.
  • 8. Eddy current chamber internal air circulation, dust pollution.
  • 9. Impeller and vortex crushing cavity of the material from the lining to significantly reduce the cost of wear and maintenance work. Production process, the stone can form the protection of the bottom, the body without wear, durable.
  • 10. Installation in a variety of ways, removable installation.
  • 11. Products were cube, bulk density, iron pollution. Can be used for stone finishing machine ultra - fine milling machine failure and troubleshooting methods.
Raymond Mill

Raymond Mill is now more commonly used milling equipment, which uses a foreign advanced manufacturing process, is a highly efficient, high-fine powder equipment. Raymond Mill production costs are low, stable operation, cost-effective, by the majority of customers welcome, can be used for calcite, marble, limestone, cement, activated carbon and other ore processing, it is in the chemical, building materials, refractory Materials, metallurgy, pharmaceutical and other industries widely used. Let's take a look at the structure and working principle of Raymond Mill.

Safety procedures for Grinding mill

Grinding mill personnel, each class before the start of the mill to check, and to the oil injection hole. Such as the discovery of abnormal machines, not boot, and timely reporting to the relevant leaders. First, before the boot

  • 1, check the mill inlet magnet, to see if there is iron in time to clean up.
  • 2, start the cycle booster pump, check the water to see the water, return water is normal.
  • 3, milling machine spindle two sets of bearings must be filled before the oil. Note: 12 hours of normal work when the butter cover 3-4 times the injection of oil.
  • 4, each class cleaning dust bag, to prevent bagging.
  • 5, check the magnet, water, oil and sieve without exception, push the main power box and vice power box power switch.
Boot of grinding mill
  • 1, before the start of the fan to open the fan, the switch fan to work properly, turn on the order: turn on the host --- to the main power box green light --- the host into the high turn --- all the main and no exception after the start Feeding --- After cutting the host current control between 70A-80A.
  • 2, the normal operation of the mill to check the various parts of the motor, with the back of the hand to test whether the motor overheating. If there is a certain part of the motor hot or abnormal sound, should immediately report to the team leader to deal with. Note: It is forbidden to check whether the motor is overheated directly with the palm of your hand during the inspection.
  • 3, the ground check whether the iron mouth iron, if it should be shut down in time to clean up.
  • 4, the normal operation of the machine prohibited by hand or other items touch the motor and mechanical rotation parts and wiring.
  • 5, the normal work, the feed can not feed too much (generally not more than 16HZ), so as to avoid the phenomenon of motor overload caused by stuck.
  • 6, in the milling process to hear abnormal sound, should immediately stop maintenance, troubleshooting and the machine will be exhausted before the re-start.
Shutdown of grinding mill
  • 1, stop the first stop to feed, the host current down to 30A
  • Stop the following host. After the host stops rotating: in turn stop the fan, off the fan, and finally turn off the main power box power switch.

  • 2, after the shutdown cleaning equipment and on-site health,Turn off the main power supply and booster pump power supply.
  • 3, the equipment inspection requirements:
  • 1, the daily inspection of the main motor is overheating;

    2, check whether the bearing part of abnormal sound, and regular refueling;

    3, every day before the boot to check whether the normal cooling system;

    4, check the safety device is normal
