Cement Mill Introduction:
Cement mill is the mill for the manufacture of cement. Cement grinding process is simple, but there are still many enterprises in the cement grinding process equipment design and technical improvements Ken Duojia input shaft kiln simple transformation grinding station can do after the fact, this is now species completely wrong concept. He said, from the industry point of view, this traditional concept of corporate CEOs must break must be a rational look at this issue, Otherwise, even if the savings in the current design of less than 2% of its total investment costs, but the loss of may be the long-term interests.
In addition, the cement grinding equipment to large-scale, and must go through the formal system planning, optimization and overall design. Professional and technical personnel from the the formal Design Institute out of the entire market and new technology industry more aware of the advantages of each cement plant to focus, tailored for the enterprise made a state-of-the-art, clean production, standardized professional equipment; Second, large-scale cement grinding equipment, designed not only for businesses to save power consumption through consolidation planning, reduce costs, and can conserve resources for the country. In addition, from the perspective of circular economy, improve grinding technology, large-scale equipment to achieve energy conservation also helps cement industry.
Vertical Roller Mill:
The vertical roller mill is my chief engineer of the wearable device expert Mr. Bai Yinghui in many years engaged in high fine powder processing on the basis of the experience, devoted themselves to developing a new type of milling equipment, thus creating an efficient international industrial milling, a new era of low energy consumption. vertical roller mill is used to crush the barite, limestone, ceramic, slag, etc. Mohs hardness of not greater than 9.3, humidity below 6% of non-inflammable mines, metallurgy, stone industry, building materials and other industries more than 280 kinds of materials for high fine powder processing, product size is 80-425 mesh range adjustment (the smallest 1,000 head). The machine can add special device can produce 30-80 mesh coarse powder.
How Vertical Roller Mill Cement Mill Works?
Mill the whole work process (grinding material process): large block material crushing by jaw crusher to the desired particle size, hoist the material sent to the hopper, the material and then by vibrating feeder evenly quantitative continuously fed into the grinding chamber grinding powder after grinding the child has been taken away by the fan airflow classification classifier machine to meet the fineness of the powder into the cyclone collector with the airflow through pipes to separate collection discharge is the finished powder, stone tube. The airflow back by the upper end of the cyclone powder collector duct inhalation induced draft fan. The machine the entire air system is a closed loop, and is a circulation flow in the negative pressure state.
In the grinding room has a certain moisture content in the material to be ground, grinding heat generated when grinding indoor gas evaporation expansion changed the gas flow, as well as the whole pipeline junction Mifengbuyan, outside gas inhalation, the circulating air air volume increased airflow balance to achieve this by adjusting the exhaust pipe between the fan and the host, and the excess gas into the bag filter, the residual gas into the the micronized collection down residual gas purification discharge.
Host the work process is motor driven host spindle, the upper end of the spindle connected to the roller suspender roller device through the cross arm shaft hoisting the roller suspender and a swing pivot, not only around the central axis of rotation, while in the centrifugal force next round grinding rolls along the grinding ring rolling, grinding roller frictional effects and rotation. The lower end of the roller suspender is equipped with blade knife, shovel blade mounted on the turret of the lower flange tilt the front of the blade near the grinding chamber liner, back-end roller and grinding ring wedge gap shovel between the knife and grinding roller with the transfer process materials shovel throwing feeding roller mill ring is squeezed, crushed. From the the grinding ring into the grinding chamber at the bottom of the airflow of small particles of powder with selected powder, stone milling achieve the purpose.
Classifier speed motor to drive the blade rotation on the turntable, the eddy current effect on the formation of powders, since grading. The speed of the blade speed is adjusted refined powder particle size. To get a more fine-grained powder midnight, it is necessary to improve the speed of the blades, the powder will be thrown to the bottom of undesirable coarse sub due to its own gravity into the grinding chamber for regrinding, qualified refined powder through the blade with the air sucked into the cyclone powder collector, the airflow and the powder will be separated, the powder will be collected.
Cyclone powder collector has played a very important role in the performance of the mill, with the powder airflow into the powder collector is the state of the high-speed rotation, pending airflow powder sub separation airflow contraction to move to the center to the cone with the cone wall the bottom Time (a rotating upward gas stream from stream natural length) is formed cylindrical, then the powder will be separated Drop collected. The lower end of the powder collector equipped with upper and lower sealing valve falling powder will take away from the powder collector through the sealing valve discharge. Due to the the rotating core airflow upward to form the cone at the end of the powder collector negative pressure, sealing the lower end of the powder collector demanding, must be strictly separated from the outside air, otherwise the powder will be collected re core the airflow away, which directly affects the output of the machine, so the lower end of the powder collector equipped with a sealing valve, its role is to isolate the negative pressure gas within the external positive pressure gas and powder collector, this is a very important components, such as do not install the upper and lower sealing valve or top and bottom sealing valve Mifengbuyan powder will result in no less stone serious impact on the whole production.
