High Capacity Low Energy Consumption Vertical Roller Mill Rotary
Kiln Lime Production Line
Description
Vertical grinding machine
The HVM series ultra-fine vertical grinding machine can be widely
used in industries such as chemical engineering, metallurgy,
non-metallic minerals, etc., especially in the field of ultra-fine
grinding and processing of white non-metallic minerals. It has
excellent performance and can provide high-quality fillers and
additives for industries such as papermaking, coatings, plastics,
rubber, PVC, ink, etc. It can be widely used in large-scale
superfine dry powder processing of non-metallic minerals such as
calcite, marble, limestone, dolomite, barite, talc, kaolin,
dolomite, wollastonite, gypsum, feldspar, pyrophyllite, etc.
Applicable Materials:
Various materials such as cement, slag, steel slag, iron ore, and
mineral processing ores
【 Feed particle size 】: 80 μ mR 12~15%
Production capacity: 30-720 t/h
【Application】:
Various materials such as cement, slag, steel slag, iron ore, and
mineral processing ores
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.

Main features of the product
1. Efficient and energy-saving:
(1) High grinding efficiency and low energy consumption, compared
to ball mills, the energy consumption is 40% -50% lower;
(2) Large single machine production capacity, capable of utilizing
low valley electricity;
(3) Vertical grinding technology and equipment are vigorously
advocated new technologies for energy conservation and consumption
reduction, which are conducive to enhancing the competitive
strength of enterprises in the powder industry in this region and
even across the country;
2. Low comprehensive investment cost:
Integrating crushing, drying, grinding, and conveying, the process
flow is simple, the system equipment is few, the structural layout
is compact, and the floor area is only 50% of that of the ball
mill. It can be arranged outdoors, with low construction costs,
directly reducing the investment cost of the enterprise.
3. Easy maintenance and low operating costs:
(1) The grinding roller can be turned out of the machine using a
hydraulic device, and the replacement of the roller sleeve lining
plate and the maintenance space of the mill are large, making the
maintenance operation very convenient;
(2) The grinding roller sleeve can be used upside down, extending
the service life of wear-resistant materials;
(3) Before starting the machine, there is no need to place fabric
on the grinding disc, and the mill can be started without load,
eliminating the difficulty of starting the machine;
(4) Low wear, special materials are used for the grinding roller
and disc lining plate, resulting in a long service life;
(5) High degree of automation: The automatic control technology
adopts the Siemens series PLC from Germany, equipped with an
automatic control system, which can achieve remote control and easy
operation. The workshop can basically achieve unmanned operation,
saving operating costs;
