Vertical mill working principle and advantages of analytical

Vertical mill are used a wide range, large market demand, and this is closely related to the performance of vertical mill itself. vertical mill improve the efficiency of production and processing, production, and product size have been improved to optimize the disadvantages of grinding machine, greatly increasing the output while also saving energy. Today, Chaeng will introduce that vertical mill working principle and main advantages to help you learn more about the vertical roller mill !

1, vertical mill works principle.

Vertical grinding mill principle: grinding material from the feeding device into the air lock disc rotates, the centrifugal force, the material surrounding the disc moves into the grinding roller. Under the action of the pressure roller was crushed. At the same time, grinding the material after being blown air ring at the high-speed air of suspended material drying, hot air into the powder by the separator grading, qualified fines collected by the collecting device for the product, failure coarse powder fall to disc re-grinding, so the cycle to complete the whole process of grinding operations and achieve material crushing, drying, grinding, separator integrated operation. Vertical mill mainly by the separator, roller device, disc device, the pressing portion of the device, reducer, motor housing and other components. A splitter is a highly efficient, energy-saving separator apparatus. Roller compaction is used the material for grinding parts. Disc fixed to the output shaft of the reducer, is the place where the roller compacted material. Pressing means is a pressure roller grinding mill to provide parts to provide sufficient pressure to crush material to the roller.

2, vertical mill advantage.

(1) significantly reduced production and investment costs: vertical mill system process is simple, compact layout, small floor area, covering about 70% of ball mill system, milling system architectural space of about 60% and may open layout directly reduce investment costs. And vertical mill separator itself, does not require additional separator and lifting equipment. The grinding dust and gas can be directly collected by the bag filter or electrostatic precipitator.

(2) high production efficiency, energy saving and environmental protection: the use of the material layer vertical mill grinding principle of grinding materials, low energy consumption, grinding system power consumption by 20% to 30% over the ball, and with the increase of raw water, electricity the effect is more obvious. Vertical mill and milling system energy savings compared to 30% to 40%. Vertical mill does not work in a ball mill balls collide, the impact liner metal crash, so the noise is small, less than the ball 20 ~ 25dB. In addition, vertical mill fully enclosed system, the system working under negative pressure, no dust, clean environment.

(3) material drying capability: transportation of materials vertical mill of hot air, in the water when grinding materials with large inlet air temperature can be controlled, so that products meet the required final moisture. In the vertical mill can dry - grinding into the grinding material moisture up to 15% to 20%.

(4)easy aperation, easy maintenance: equipped with automatic control system, which enables remote control, easy to operate; through the maintenance tank, turn rotating arm can be quick and easy to replace the roller sleeve, liner, reduce business downtime.

(5) easily detectable product quality: the chemical composition of the product stability, particle size distribution are homogeneous, it is conducive to firing. Material in the vertical mill residence time of only 2 ~ 3min, and in a ball mill will have 15 ~ 20min. Therefore, the chemical composition and fineness vertical mill products can be quickly measured and corrected.

(6) wear small, high utilization: As the vertical mill running roller and disc no direct contact between the metal, wear, metal consumption per unit of product is generally 5 ~ 10g / t.

Fully visible, because of the prevalence of vertical mill now basically meet customer demand for grinding equipment, believe that as technology continues to improve, vertical mill performance will be more perfect, and the only way to grasp market, will not be eliminated!
