Description. The Chain Drive block represents a power transmission system with a chain and two sprockets. The chain meshes with the sprockets, transmitting rotary motion between the two. Power transmission can occur in reverse, that is, from driven to driver sprocket, due to external loads.
A drive portfolio optimized by durable gear couplings perfectly suited for rough operating environment. Prepared for all eventualities In order to avoid deformation following an abrupt stand-still, the drive system is often equipped with an emer-gency device in the event of a power failure, which can be provided by Siemens.
Kiln Drives Providing a cost effective, durable and easily maintainable mechanical power transmission solution is key to the successful operation of kiln applications in the cement industry. Our adaptable range of mill drive solutions cover power ranges from 1-9 MW, with custom engineered solutions available for applications above 9 MW.

The pyroprocessing system involves three steps: drying or preheating, calcining (a heating process in which calcium oxide is formed), and burning (sintering). Calcination is the core portion of this process. The raw meal is continuously weighed and fed into the top cyclone of the preheater. The material is heated by hot air rising from the kiln.
The length of such a kiln can be well over 100 meters. In this type of kiln, the limestone is added at the slightly higher end and slowly passes through the kiln due to the rotation. All drive elements must also be inclined accordingly. FLENDER offers the latest drive systems for rotary kilns.

Induced draft (ID) fan systems often use louvers or variable inlet guide vanes to control the flow of exhaust through the fans. An ID fan system can be made more efficient by using a variable frequency drive (VFD) to control the fan speed, which controls the air flow without adding restrictions to …
Sep 01, 2001 Improper drive maintenance is the biggest source of belt drive problems Angular misalignment (Fig. 7) results in accelerated belt/sheave wear and potential stability problems with individual V-belts. A related problem, uneven belt and cord loading, results in unequal load sharing with multiple belt drives and leads to premature failure.
