vertical grinding mills and rock grinding mill
vertical grinding mills,rock grinding mill,lime grinding mill
The VM series vertical mill is an improved vertical grinding mills equipment after many years¡¯ concentrated design according to a market need. The vertical mill is designed to solve the problem of technological problems of low production, high energy consumption and developed on basic of absorbing advanced European technologies.
Features of grinding mills south africa
Improved raymond mill has stable performance, strong adaptability, less environmental pollution and meets the requirement of energy-savings.
Zenith Company has researched and developed Raymond mill for 30 years, during this period, we did a number of improvements on it. At present, relying on the knowledge of the Institute of Raymond Mill summed up, we develop our own new generation of raymond mill.
Low construction expense:
(1)The rock grinding mill is simple in process. Comparing with ball mill, its soil taking can be about 50% reduced, construction expense can be reduced by about 70%, which is small in construction area and space.
(2)The vertical mill is a combination of crushing, drying, milling, grading and transferring, which has simple system and compact structure. It can be allocated in the open air and its construction expense will be lower.
Operation is easy and reliable
(1) Automatic controlling device is installed, which can enable long distance control and is simple in operation.
(2)There is a device to prevent direct contact between roller and mill plate, which can prevent the equipment from fragmentation serious vibration.
In the design of the entire system, improve the traditional two-stage collection to four-stage collection. The former two collections adopt circular negative pressure closed locking collection without dust overflowing; the latter two collections adopt controllable overflow dry-wet series collection to eliminate dust overflowing. The whole system can collect ultra-fine powder and simultaneously prevent or reduce the pollution to the surrounding environment.
New lime grinding mill workflow
Crush large bulk materials to required particle size by electric grinding mill, send them to the storage hopper by elevator, then transform to grinding room by vibrating feeder uniformly, quantitatively and continuously, grinded powder are took away soon by fan airflow. After being classified, powders that meet the fineness enter into cyclonic collector with the air flow for separation collection, and then discharged though pollen tube, that is refined powder. The whole airflow system is closed loop, and circularly flows in the positive and negative pressure state.
