Cement is especially suitable for special occasions such as concrete, precast concrete, fair-faced concrete, GRC products, adhesives, etc. It is commonly used in colored pavement bricks, permeable bricks, cultural stone, sculpture crafts, terrazzo, wear-resistant floor, putty, etc. The high light reflection performance makes the roadside stone, road sign and road central divider have higher traffic safety performance. White cement is mostly used for decoration, and its manufacturing process is much better than ordinary cement. It is mainly used for the gap of the white porcelain tile, and is generally not used for the wall surface because the strength is not high. Available in the building materials market or in the decorative materials store. The production process of cement, using limestone and clay as well as silica as the main raw material, is crushed, compounded and ground to make raw meal, fed into the cement kiln to calcine the mature material, and added with appropriate amount of gypsum (sometimes mixed with mixed materials or Admixture) is ground.

high-performing gear unit for your ball mill

high-performing gear unit for your ball mill

Developed in 1966, our two-stage planetary gear unit guarantees optimum power transmission and speed reduction for your ball mill. The standard for central driven ball mills in the cement industry today, our MAAG GEAR CPU Gear Unit drives hundreds of raw and clinker ball mills all around the globe.

The simple design holds the secret to the gear units high efficiency. Two co-axial planetary gear stages are arranged one after the other. Each stage includes three planet wheels mounted in a rotating planet carrier and internal toothed coupling guarantees reaction-free power transmission from the first planetary stage to the second. This setup is the most efficient gear arrangement and guarantees optimum power flow from the main motor to your horizonal mill with the fewest possible rotating parts, tooth contacts and bearings.

Your requirements for the grinding process determine the configuration of this gear unit, which can be tailored to suit many application areas. All installations take into account local circumstances and plant specifications, such as motor and mill speeds. With power ranges from 1,000 to 10,000 kW, the MAAG GEAR CPU Gear Unit has the breadth to adapt output speed to your specifications. We can also add additional features such as water injection or a condition monitoring system.

The space-saving design of our two-stage planetary gear unit means that it takes up less room than traditional, multistage, spur gear units. While it may be smaller, it never compromises on power delivery.

Additionally, the compact size of the CPU Gear Unit simplifies transport. Assembly time is also decreased and, once the foundation is complete, the central drive gear unit is quickly installed and operational.

The design of our MAAG GEAR CPU Gear Unit has been copied many times, but never equalled in efficiency, quality and ease of installation and maintenance. The complete central drive system delivers dependable power for raw and cement grinding allowing your plant to operate with ease.

The toothed couplings installed between the main motor and the gear unit, as well as between the gear unit and the ball mill, transmit pure torque from one component to the next. In addition, they compensate for thermal expansions and mechanical deflections resulting from operating conditions.

During maintenance, the low speed ZCF coupling remains in place between the gear unit and the ball mill, while the dismounted high speed ZEXF coupling provides enough axial space to disassemble the gear unit without moving the main motor.

Ideally located beneath the main motor, the oil supply unit cools and lubricates the toothing and bearings of the CPU Gear Unit. With a high prioritisation on operational reliability, the oil supply unit has all necessary measuring instruments to monitor the correct lubrication of the central drive gear unit.

All of our gear units and drive systems are equipped with unparalleled condition monitoring sensors. Normally, these types of sensors keep an eye on critical operating parameters like bearing temperatures, casing vibrations, etc. and trigger a mill shutdown in the case of exceedances.

Our condition monitoring system does much more. It lets you set up condition-based preventive maintenance that uses continuous monitoring and data analysis to detect wear and tear at an early stage. With this enhanced information, we help you plan maintenance and servicing in advance reducing downtime and keeping your plant running smoothly.
