Hengcheng has gradually formed a complete set of research and
development, production, sales, and service systems after decades
of quality accumulation. Through innovative development, it has
gradually produced a series of Raymond grinding machines, slag
vertical mills We are an ideal manufacturer and supplier of
grinding equipment, equipped with advanced equipment such as
ultra-fine grinding machines and ultra-fine vertical grinding
machines, with products and services spread throughout countries
and regions such as Asia, Africa, Europe, and the United States.
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.

Product advantages
1. Efficient and energy-saving:
(1) High grinding efficiency and low energy consumption
(2) Large single machine production capacity, capable of utilizing
low valley electricity;
2. 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 apply fabric
to 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: Automatic control technology, easy
to operate, the workshop can basically achieve unmanned operation,
saving operating costs;
3. High reliability
(1) Adopting a grinding roller limit device to avoid severe
vibration caused by material breakage during the working time of
the mill;
(2) Adopting a new type of roller sealing device, the sealing is
more reliable, and there is no need for a sealing fan, further
reducing the oxygen content in the mill and achieving better
explosion suppression performance.
4. 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.
5. Stable product quality:
(1) The material stays in the mill for a short time, which makes it
easy to detect the particle size distribution and composition of
the product, and the product quality is stable;
(2) The product has uniform particle shape, narrow particle size
distribution, good fluidity and strong adaptability.
6. Environmental protection:
(1) The entire system of HVM vertical grinding machine has low
vibration and low noise;
(2) The system is sealed as a whole, operates under full negative
pressure, and there is no dust leakage, basically achieving a
dust-free workshop.
