ball mill - retsch - powerful grinding and homogenization
Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications.
RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill Emax and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with only minor warming effects. These ball mills are also suitable for mechano chemistry. Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. These ball mills are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery. Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding to analytical fineness. They are used for the most demanding tasks in the laboratory, from routine sample processing to colloidal grinding and advanced materials development. The drum mill is a type of ball mill suitable for the fine grinding of large feed sizes and large sample volumes.
lum ultrafine vertical mill
As a new type of superfine grinding equipment, the LUM ultrafine vertical roller mill integrates powder grinding, separation and transportation. With years experience in mill production, the LUM ultrafine vertical roller mill are designed by our company, basing on vertical mills, we introduce Taiwans grinding roller technology and Germany powder separating technology.
As a professional medium and high-end processing equipment in plastic master batch, PVC, artificial stone, electric cable, non-woven fabrics and other industriesLUM Series Ultrafine Vertical Grinding Mill is mainly used for the ultrafine grinding of calcite, marble, limestone, talc, dolomite, barite, kaolin, wollastonite, gypsum, feldspar, pyrophylite and other non-metallic mineral ores.
The grinding curves of the roller shell and lining plate are uniquely designed based on the ultrafine pulverization principle, which makes it easier to form material bed, improving the grinding efficiency and increasing the proportion of finished products from the primary grinding.
According to the material bed pulverization principle, the materials stay a short time in the mill to reduce the repeated grinding.As a result, the iron content in the finished products is low and the whiteness and purity of the product are high
By adopting PLC control system, major parameters like grinding pressure, rotating speed of grinding disc and speed of classifier etc. can be accurately controlled to achieve accurate cutting size and stable quality.
Thanks to the use of ultrafine pulverization and multi-rotor separation, LUM series ultrafine vertical grinding mill saves energy by 30% to 50% compared to a common type mill when producing the powder of the same fineness, which achieves better economic effects.
The whole equipment is well sealed and the system operates under negative pressure. Therefore, powder and dust are prevented from flowing out of the system. It is environmentally-friendly and meets the national environmental protection requirements.
The materials drop on the grinding plate center through the screw feeder and evenly move outwards under the action of centrifugal force of the rotating grinding plate driven by the reducer; Large materials are crushed and ground by the grinding rollers when passing through the grinding area, while smaller materials form a material bed by extrusion for further inter granular crushing. The crushed materials continue to move towards the mill edge until being taken into the classifier by the air flow from the air inlet.
The powder particles failing to meet the particle size requirement fall back on the grinding plate for further grinding while the qualified powder particles are collected in the pulse dust collector with the air flow and discharged as finished products. However, the iron blocks and other sundries mixed in the materials move along with the materials towards the edge of the grinding plate due to their own weight. They fall into the lower chamber of the mill and then be discharged out of the mill through the slag discharge opening by the scraping plate.
