Vertical mills, as large-scale grinding equipment, are widely used in industries such as building materials, power, metallurgy, chemical engineering, and non-metallic minerals. Hefei Hengcheng HVM vertical mill adopts international vertical mill technology, integrating crushing, drying, grinding, powder selection, and transportation, ensuring the continuity and stability of production and improving grinding efficiency. Hefei Hengcheng can customize according to the material characteristics of customers, with flexible configurations to meet their personalized grinding needs.
Operational Principle
The electric motor drives the grinding plate to rotate through a reducer, and the material falls into the center of the grinding plate from the feed inlet, while 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 moisture are dried during contact with hot gases to achieve the required product moisture.

Product advantages:
1. Reliable performance
The new grinding roller sealing device has more reliable sealing performance, and the grinding roller limit device effectively ensures the severe movement caused by material breakage.
2. Single machine production capacity is large, energy consumption is more economical, and compared to ball mills, energy consumption is 40-50% lower.
3. Clean and environmentally friendly
The entire system has low vibration, low noise, overall sealing, and full negative pressure operation, which is a new energy-saving and consumption reducing technology.
4. Automated operations
PLC fully automatic control system, remote control, and easier operation.
5. Excellent quality of finished products
The finished product has good particle morphology, narrow particle size distribution, good fluidity, high whiteness and purity, which can enhance the competitiveness of the powder market.
6. Low civil engineering costs
The complete system has fewer equipment, a compact structural layout, and a small footprint. Compared to ball mills, it saves 50% and can be arranged outdoors, resulting in low civil engineering costs.
7. Easy to maintain
The grinding roller can be turned out of the machine using a hydraulic device, and there is a lot of space for replacing the roller sleeve liner and repairing the mill. The grinding roller and grinding disc liner are made of special materials, and the service life of the entire machine is longer.
Service Commitment
Adhere to the service concept of "trinity" of pre-sales, during sales, and after-sales:
1, Pre sales service:
Provide users with product performance introductions, quality assurance system certificates, enterprise profiles, and other materials to fully understand Hengcheng's products, production line solutions, and technical advantages. Provide technical consulting services for users and customize production line solutions for customers.
2, In sales service: that is, to let users know and trust to purchase Hengcheng's products
(1) Inspection
Before leaving the factory, the product undergoes various performance tests at the testing center; Provide customers with product testing data and test reports.
(2) Training
In order to enable users to better operate, maintain, and manage equipment, the company will arrange engineers with years of experience to provide training and guidance to the technical personnel working.
(3) Installation
The company appoints engineering and technical personnel with years of experience in installation and commissioning to provide on-site guidance on installation and trial operation work;
3, After sales service:
We have a long-term service team for the production line, with good technology and responsible after-sales service. All members have over 5 years of work experience and are able to provide timely, efficient, and comprehensive scientific after-sales service to customers. We can provide customers with after-sales service throughout the entire process of self engineering construction, production line equipment installation, production line debugging, until the production line meets the standards and reaches production capacity, solving various difficulties and miscellaneous problems encountered by customers, and providing thoughtful, meticulous, and comprehensive after-sales service.
We firmly believe that it is the customers who have given Hengcheng the opportunity to develop. Putting customer interests first is the purpose of Hefei Hengcheng's service, and satisfying customers is our eternal pursuit!
