Energy Saving Limestone Powder Grinding Equipment Vertical Mill Manufacturer
6-80t/h Limestone Powder Mill, Large Heavy Calcium Grinding Equipment, Vertical Mill Manufacturer
Description
Limestone vertical grinding machine is a new type of grinding
equipment designed and developed by our company based on years of
production experience in various vertical grinding machines,
drawing on domestic and foreign ultrafine grinding theory and the
company's research and development team. Limestone vertical mill is
an ideal equipment in the limestone grinding industry that
integrates crushing, drying, grinding, and graded conveying. The
stone powder vertical mill is well sealed, and the system operates
under negative pressure. It is environmentally friendly and clean,
meeting national environmental requirements.
Limestone, as a cheap and highly valuable desulfurizer, is highly
popular in the field of desulfurization applications in power
plants. The preparation of limestone desulfurizers using vertical
mills with high cost-effectiveness, fast grinding efficiency, and
high powder yield is an ideal choice for creating rich profit
value. Hefei Hengcheng is based in the field of limestone
desulfurization, and as a highly responsible mechanical
manufacturer, we continue to promote more ideal grinding systems
for the industry. Among them, the limestone vertical mill has
reasonable prices, higher cost-effectiveness, and high powder
production efficiency, making it an ideal equipment loved by the
industry.

The quality of the threshing machine commonly used for limestone
and limestone is crucial to the desulfurization efficiency. The
coal slag discharged from the boiler itself is used as the basic
core particle of the desulfurizer, a small amount of lime is added,
and water is added to mix evenly, so that the lime is wrapped on
the surface of the coal slag particles to make a calcium based slag
desulfurizer with large specific surface deposit. Since the raw
material for preparing the desulfurized limestone powder is
limestone ore, grinding limestone becomes a key link, The vertical
mill for processing limestone is an ideal equipment for
professional application in the field of desulfurization. The
vertical mill has stable operation, reliable performance, and
higher cost-effectiveness, making it an equipment for limestone
processing. Hefei Hengcheng focuses on the field of limestone
desulfurization, specializing in the preparation of limestone
desulfurization vertical mills to meet the production needs of the
industry and continuously promote cost-effective grinding equipment
for the industry.
As an exclusive equipment in the field of limestone
desulfurization, Hengcheng HVM vertical mill has its own
characteristics and processing characteristics. This equipment
integrates drying, grinding, grading, and conveying. The entire
equipment has a scientific and reasonable product design structure,
which can solve the problems of low production capacity, high
energy consumption, and high maintenance costs of ordinary grinding
machines. All performance is at the advanced level in the industry.
The entire equipment mainly consists of a host, a feeder, a
classifier, a blower The pipeline device, storage hopper, electric
control system, collection system, etc. are composed of scientific
and reasonable configuration, which greatly reduces the
comprehensive investment cost. The system is sealed as a whole,
operates under full negative pressure, and can achieve no dust
leakage. It is a energy-efficient and environmentally friendly
equipment strongly advocated in China, helping efficient, clean,
and energy-saving production in the desulfurization field, and
contributing more to the cleanliness and purification of the
environment.

etc., with advanced product performance.
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.
