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
Extremely compact arrangement
No foundation for the gear reducer
No complicated drive adjustments
The motor can be installed separately from the gears
Does not need to be run in
Low staffing level for operation monitoring
Environment-friendly due to light sealing, No grease required
High availability
High efficiency level as no coupling required on the mill side
