At present, most of coarse manufacturers adopt Raymond mills and ball mills, which can meet the current market demands to some extent. However, with the development of industrial modernization, environmental policies become more and more strict. Energy conservative, environment protection and high yield will be the future market demand. Based on this and adopted with German and China Taiwan superfine vertical grinding technology, Dongguan Vsunny Machinery Co., Ltd developed the VSCM series coarse vertical grinding mill. It use the high-class wear-resistant parts, and the fineness of ground powder product will be from 60~500 meshes. It is a high-tech machine with drying & grinding capability featured by high efficiency and energy-saving, and is widely applied in power plant desulphurization, construction putty powder, gypsum powder production and paper making industries.
VSCM series coarse grinding mill can be widely used in mass production of super fine powder of non-metallic minerals including calcite, marble, limestone, coarse whiting, talc, barite and dolomite, etc. The fineness can be 60~500 meshes.
The motor under the main unit drives the reducer to run the grinding table, materials are fed into the main grinding unit through the screw conveyer, and fall to the central grinding table under the action of gravity. Then the material is thrown out of by centrifugal force, and move to the side area of the grinding table and form a material layer. Under the effect of the gap pressure of the roller and the grinding table, the materials are grinded up after extrusion, grinding and cutting. The grinded materials are blown up with the airflow of the annular air duct; coarse materials are blown back to grinding table for further grinding; fine materials are blown to powder classifier with hot wind for classification; qualified fine powder are output with airflow and go through dust filter then collected by powder collector, which are the finished products; unqualified coarse powder are screened through the rotor blade of the classifier and dropped onto the grinding table center for further grinding; larger-grained materials are dropped into the lower housing and discharged to the material hopper.
1.High grinding efficiency with low operation cost. The principle of vertical roller mill is to use material layer to grind the materials. This kind of mill has low energy consumption. The electricity consumption is 20%~35% lower than that of ball mill, and the electricity conservation is more obvious with the increase of material moisture content;
2.Low cost of construction and investment. All the processes of grinding, drying, milling, powder screening and transporting are realized in one vertical grinding mill; no need for extra drying, screening or improving equipment. The dedusting part is collected by a high concentrated pulse dustor. The whole unit is compact and the construction area is about 50~60% of the ball mill. The technological process is simple and requires small space;
3.The operation is easy and reliable. The operation and maintenance are also simple and convenient;
4.The products have stable quality and can be produced in a large amount;
5.The specially improved roller, grinding table, diversion system and internal recirculation system greatly improved the grinding efficiency of the equipment. The special wear-resistant parts also prolonged the lifetime of the grinding mill;
6.The eco-friendly equipment has low noise and less dust with clean operation environment. The roller and the grinding table has no direct contact, which lowered the noise. The pulse dustor also makes the operation environment clean;
7.The grinding process can be fully controlled by computer; simple operation with less manpower; the grinding products can be controlled and adjusted.

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!
