Application

Vertical roller mill integrates crushing, grinding, powder concerntration, drying and conveyoring. It can be widely used in cement, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder

Applicable materials: Stone crusher is used for crushing over 120 kinds of rocks, such as limestone, granite, quartz, basalt, river stone, gold ore, iron ore, coal, gravel, aggregate etc. Different final output size could meet your different needs.

  • Quality Assurance

    Lower Investment: Combination of crushing, drying, grinding and conveying, simple process flow, reasonable and compact layout, lower foundation cost and workshop cost in the field.

  • Customized Scheme

    Easy Maintenance: hydraulic device makes maintenance more convenient.

  • High Yield

    Stable Powder Quality: Materials stay in the grinding mill for a short time, which can reduce repeated grinding and is easy to detect and control the grain size and chemical component of the product.

Working principle

Vertical rolling mill has two pairs of grinding rollers. Each pair of roller is composed of two narrow rollers and mounted on the same axis and can rotate at different speeds. The motor driving reducer make grinding plate to rotate. Raw material is sent to the center of the rotating grinding plate by the locking air feeding equipment. Under the action of centrifugal force, the material moves to surrounding area of grinding plate and enters the grinding roller slide.Under the action of roller pressure, the material is crushed by extrusion, grinding and shearing. At the same time, the grinded material is flowed by hot air upward from the wind ring. The coarse granularity will be back to mill to regrind and suspended material will be dried. Fine powder following hot air is taken to classfier system. Qualified powder enters the powder collector with airflow as finished products. Unqualified powder falls to regrinded with new feeding material together. This cycle is continuous to complete the whole grinding process.
