Magtorq, the innovative and experienced Planetary gearbox manufacturer in India is dedicating its services to the industry by presenting our product range in Sugar mill area. Sugar industry once considered as conventional and old fashioned is no longer so. In fact this old style industry is overtaking many other industries in upgrading the technology and judicious use of raw material, the cane.
Figure I. Shaft mounted Torque balanced drives (GRPF)
This arrangement requires almost zero mounting and alignment efforts. The half coupling can be separated and mounted on the machine shaft and locked in place. The gearbox with the other part of the half coupling is bolted in place. The torque arms are interconnected and the system is ready for electric connections and operation.
Figure II. Drive system for three driven roller Mills
Gearboxes are flange mounted to the bearing block with the help of a mounting spacer. The gearbox have hollow output shaft with internal spline or hollow square (to customer specifications) to match the roller shaft. This arrangement simplifies the drive mounting by avoiding,
.Torque arm
.Heavy foundations
.Expensive Couplings.
The sugar experts also claim Better Extraction, higher efficiency and low maintenance on the rollers and its bearings.
Figure III. Planetary Gearbox for mills
A very compact drive system compared to old method of power transmission from turbine to mill through High and low speed gearboxes followed by Pinion and Gear arrangement driving the sugar mills.
Figure IV. Helical Planetary Gearbox for Mills
These gearboxes give a high flexibility of ratios with a helical stage at the input. With standard planetary gear system providing compactness and a helical gear pair at input to provide the flexibility on ratios.
Figure V. Combination Gear Drives for Mills
The transmission of power to the mill takes place from a bull gear at the final stage. This bull gar is made smaller by multiple pinions meshing with the bull gear. The load sharing between the pinions are ensured by the function of planetary differential. The system is a combination of conventional gear & pinion system and planetary thus improving its maintainability.
GENERAL ARRANGEMENT FOR LUBRICATION:
Mill gearboxes are supplied complete with lubrication system with adequate capacity to dissipate the lost power in the system. General arrangement of Lubrication system is given below. The system will be optimized with every supply for the ambient temperature at site of installation.
Magtorq manufactures a wide range of planetary gearboxes for mill based on the given below ratio and torque ratings.
Standard Ratios
| 107 | 128 | 155 | 182 | 197 | 223 | 254 | 277 | 304 | 333 | 367 | 407 | 452 | 478 | 506 |
Output Torque Ranging from 744 kNm to 5816 kNm
As ever, Magtorq is always committed to work for customer if the application requirement falls beyond the above specified range.
