open circuit or circulatory closed-circuit grinding Mill Tube Grinding mill
CITIC Tube Mills are space-saving, compact, high on performance and low on maintenance. This is primarily due to the support bearing design and the mill drive used. The mill is shell-supported, mounted on slide shoe bearings at both ends and made completely as a welded design. The mill with the compact drive version features an INTEGRAL DRIVE, whose planetary gear is mounted to the mill flange. CITIC Tube mills are the result of the most advanced calculation and simulation methods, backed by years of experience. Worldwide we have designed and built more than 1,000 tube mills.
Our driving force
The standard CITIC mill is shell-supported on slide shoes and has a central drive. Torque transmission is effected via the conical discharge end. This cone is welded to the mill shell and has openings for the discharge of material and exhaust gases. The drive flange is connected to the end of the cone. In this way, the drive force is distributed directly and evenly to the mill shell.
All standard types of mill drives can be connected, such as:
Central Drive
INTEGRAL DRIVE
Girth Gear and Pinion Drive
High on performance, low on space
requirements: INTEGRAL DRIVE
Our mills for minimum space requirements are mounted on slide shoe bearings and have an INTEGRAL DRIVE. The core of this drive is a two stage planetary gear reducer, which is directly mounted on the end cone. Only one short slide seal at the motor end and a closed oil lubrication system extend the time between oil changes and reduce the risk of entering of dust particles. Installation is fast and easy. No time consuming adjustments. Our INTEGRAL DRIVE is the most economic drive due to its high availability and a mechanical efficiency level of almost 99%.
The main features at a glance
