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