By using variable speed drives (VSD) to control high efficiency motors in your cement manufacturing process, you can reduce energy consumption significantly compared to traditional fixed speed motors. VSDs also provide you an accurate control for your processes, and our PLCs help all your processes to work in co-ordination with each other. Our portfolio includes a wide range of low voltage ...

BASIC FUNDAMENTALS OF GEAR DRIVES A gear is a toothed wheel that engages another toothed mechanism to change speed or the direction of transmitted motion. Gears are generally used for one of four different reasons: 1. To increase or decrease the speed of rotation; 2. To change the amount of force or torque; 3. To move rotational motion to a ...

or 1200 rpm (20 rps) with 60 Hz power, or with a single-reduction gear drive (approximately a 5:1 speed reduction) for 350 rpm (5.83 rps). Although details of impeller types vary, axial flow impellers, such as marine propellers or three-blade hydrofoil impellers, are used most often. A typical direct-drive portable mixer is shown in Figure 21-1 and a gear drive portable in Figure 21-2. 21-2.1 ...

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. The motor is fed by a fuse-less cycloconverter that is connected to the MV network through three special cycloconverter ...

Mill drives We offer both high-speed induction and low-speed synchronous motors. High-speed motors require an intermediate gearbox. Although large mills exceeding 18,000 kW normally use gearless drives, Outotec can offer geared drives in excess of 24 MW. Smaller mills up to 450 kW are also available in a direct-driven arrangement.

Drives also are used to power roller mills for grinding different blaine of slag for cement, and for starting and running ple roller mills, ball mills, and overland conveyors. A China-based cement plant used VFDs to significantly reduce its energy consumption in its dry-process kilns, responsible for production of 1.4 million tons of cement each year.

The size range of the OK mill includes 3, 4 and 6 roller mills and includes the largest VRM sizes available with installed power over 11,500 kW. Concrete mill stands The latest version of the OK mill includes a simple concrete stand replacing the full conventional steel stand. The use of concrete stands not only saves installation time by eliminating unnecessary transportation of heavy parts ...

Because you want the grinding balls to experience a free-fall motion, i.e. cataracting motion, I would recommend you consider a rotational speed between 65 and 85 % of the critical speed of the mill.

High-pressure rolling mills and rotary kilns are particularly demanding applications that call for maximum performance and reliability from the drive systems. The grinding process must be guaranteed energy-efficient and reliable at the same time. Our planetary gear units have been used as drives in roller presses and rolling mills for decades. The product portfolio during that time has been ...
