VSLM Series Ultrafine Vertical Roller Mill was produced by Dongguan Vsunny Machinery Co., Ltd. relying on 11 years of experience in the production of ultrafine powder and based on German and Taiwan ultrafine vertical mill technologies. 90% of the team members were from vertical mill manufacturers in Taiwan. Besides, high-quality wear-resistant parts are used to develop milling equipment which in a real sense marks the first secondary classifying technology in mainland China, having product fineness of 400~6000 mesh.
VSLM Series Ultrafine Vertical Roller Mill can be widely applied to process large-scale ultrafine powder, encompassing calcite, marble, limestone, barite, talcum, kaolin, dolomite, wollastonite, gypsum, feldspar, pyrophyllite and other non-metallic minerals. After seven years of market anneal, Vsunny has built or is building nearly 20 vertical mill production lines in the mainland.
The crushed aggregates are transported by a conveyor, fall on the central grinding table along the central funnel as the computer controls the number of feeding, and throw out in the light of the centrifugal force. After being ground by a hydraulic control roller and grinding table clearance, the crushed powder rise along the updraft transmitted by the diversion trench around the grinding table. Due to the different thickness of powder, the rising speeds are different; crude powder will fall again to the grinding table due to large self-weight and is ground again together with the aggregates, while fine powder will rise with the airstream and is classified by the classifying system above the main system. Using the five or more classifier above the main system, fine powder can be initially classified. In the classification process, under the action of the centrifugal force, hydraulic resistance and gravity and so on, inferior powder greater than the convergent point will be sent back to the central hopper in the grinding miller and ground again with the aggregates; top-grade powder smaller than the convergent point will become qualified powder along with the airflow.
Advantages of VSLM Series Grinding Main Unit:
1.Strong product diversity. VSLM series grinding main unit is equipped with a turbo air classifier, which can produce a large range of product sizes. There are 30%~70% in the 2μm range, D97=4~45μm; the specific surface area is 21000 cm²/g, while products of D97=8.5μm can be directly produced by the main unit. The below data is tested by Malvern MICRO laser particle size analyzer.
2.Use optimized production line process design, VSLM series Ultrafine Vertical Roller Mill consumption is lower than vertical mill consumption of the same type.
3.After classification, the ultrafine powder produced by the main unit is characterized by a narrow particle size distribution, control gap of 2μm powder content, high profit margins and added value to produce finished powder products, and good single particle shape. Because of the diversified finished product and strong competitiveness, it has the widely available applications, such as artificial stone, plastic masterbatch, PVC pipe, wire and cable, diapers, non-woven fabrics and other industries, with such advantages as good activation effects and low oil absorption.
4.After being improved, rollers, grinding table, diversion systems and internal circulation systems can greatly improve the grinding efficiency and improve output by 15%~30% compared to the same type of domestic products, and can save electricity by 30%~60% compared to ball mills, etc.
5.With leading grinding equipment technology, the improved grinder can be operated at low vibration. Compared with Taiwan or domestic brands, VSLM series grinder has lower noise.
6.The whole system is fully closed-loop system, with small dust pollution, so the production environment is more clean and environmentally friendly.

Established in 2012, Dongguan Vsunny Machinery Co., Ltd. is a high-tech enterprise that has been engaging in research and development, design, manufacturing of ultrafine powder vertical roller mills, new ring roller mills, coarse powder vertical grinding mills, turbo air classifiers, activation modify and coating machines, feed extruders, automatic packaging machines and chemical additives.
The company is located in the economic center Changping Town in the east of Dongguan City in Guangdong Province. The plant area reaches 15,000 square meters. After many years of research and development, it has already earned more than ten patented technologies and assessed as the " Private Scientific And Technological Enterprise in Dongguan” by the Dongguan Municipal Government and in September 2015 it passed ISO9001: 2008, an international standard for quality management system. In March 2016, we also passed ISO14001:2004 environmental management system certification. At the same time, our company is the only business that can produce single and dual hydraulic vertical mills. Since its inception, under the business goal of “technology is changing the quality, excellence comes from professionalism”, our company has taken the lead in developing and designing a national brand for high-end vertical mill equipment.
We are focused on providing all types of powder manufacturers with a turnkey project comprising a whole set of ultrafine powder production lines, from crushing, transportation, grinding, classifying to the design, manufacturing, installation, commissioning, training of the whole plant equipment, as well as delivering excellent after-sales services and technical support. Because the production process is automatically controlled and has reached the international leading level, we have such advantages as more stable production lines, more environmentally friendly production environment and more exemplary product quality. In addition, we have a patch of experienced, high-quality technical and management talents with over 100 employees, of which technical personnel account for 80% and R&D personnel occupy 10%. Over the years, we continue to explore grinding areas, makes in-depth research of the most advanced grinding, classifying and modifying techniques home and abroad, insist on research and development and innovation, thereby forming a set of mature ultrafine powder production with independent intellectual property rights for vertical mill, classifying, modifying and activation processes and to be used in the production of ultrafine powder.
In order to better serve customers, our company set a vertical mill production line in Pinggui District, Hezhou City, Guangxi, with a full set of secondary and tertiary classifying systems and modifying machine production lines. We also possess MALVERN-2000 laser diffraction particle size analyzer which was imported from the UK, ore whole composition analyzer and a full set of imported equipment. Concurrently we are building a modern, multi-functional key laboratory in Changping, Dongguan, with the purpose of providing customers with on-site grinding experiments and testing experiments regarding calcium carbonate, talcum powder, barium sulfate, wollastonite, dolomite, waste ceramic tiles, and pyrophyllite, etc.
A variety of equipment we produce has been widely used in preparing various kinds of ultrafine powder in different fields, including marble, calcite, talc, barite, dolomite, kaolin, wollastonite, limestone, feldspar, mica, gypsum, pyrophyllite, ceramic, aluminum hydroxide and magnesium hydrate. Our products are well received by customers nationwide.
Based on China, Vsunny will strive to reach out to the world!
