Energy Saving Low Consumption 60t/h Large Capacity Limestone Powder Mill Vertical Grinding Equipment
Description
The vertical mill is mainly applicable to the deep processing of ultra-fine large-scale powder of non-metallic minerals such as calcite, marble, limestone, talc, barite, dolomite, brucite, quicklime, gypsum, slag, phosphate, etc.
Working principle:
The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

>>Advanced and reliable equipment
>>Equipment Environmental Protection
The vertical roller mill does not directly contact the grinding
roller and disc during operation, and there is no metal impact
sound from the ball mill. It has low vibration and noise, which is
20-25 decibels lower than the ball mill. The vertical roller mill
adopts a fully sealed system, which operates under negative
pressure, without dust, and the environment is clean.
>>High drying efficiency
The vertical roller mill uses hot air to transport materials. When
grinding materials with high moisture content, the inlet air
temperature can be controlled to ensure that the product meets the
required moisture content. In a vertical roller mill, materials
with a moisture content of up to 15% can be dried, with a wide
range of applications. Even for drying ball mills, only materials
with a moisture content of 3% -4% can be dried.
>>Stable product quality
The material stays in the roller mill for only 2-3 minutes, while
in the ball mill it takes 15-20 minutes. So the chemical
composition and fineness of vertical roller mill products can be
quickly measured and corrected, and the quality is stable.
>>High system efficiency and strong selectivity
1. The new vertical roller mill can flexibly adjust production
according to business order requirements, without the need for
low-level fine powder.
2. During the grinding process, trace amounts of modifiers can be
added to enhance the added value of the product.
3. The specially designed high-efficiency grading wheels have been
adjusted to produce various products quickly and flexibly, ensuring
accurate cutting points and reproducibility.
