in 24 hours. This high generating capacity is due to the inclusion of spare generators, to 

 the installation of units of increased capacity to allow for future extension and to the 

 operation at reduced capacity or loss of time in grinding. Also a number of engine 

 generator units are included, which, while originally installed as main units, are now 

 used as spare units. This unit of power capacity will undoubtedly decrease, as new 

 factories are erected and more of the present mills are remodelled. 



In consideration of the extent of the use of motors for driving the crushing rolls. An 

 examination of the tabulation presented shows that there is an equal amount of electrical 

 equipment yet required to completely equip the centrals with electric drive. The power 

 required to drive the rolls is about equal to that required for the fabrication. This calls 

 for an equal capacity of motors, but of a smaller number, because of the higher ratings. 

 The generator equipment for the roll motors is less than for the fabrication, since the 

 latter includes spare capacity, which will also serve for the roll motor generators. 



In the season just past, the sugar on hand and produced was, in most cases, sold at a 

 loss, in order to provide funds for the current expenses. The centrals in the greatest 

 need for new machinery to reduce their manufacturing costs suffered the greatest loss. 

 The recovery will therefore be slow, but it is expected that at the close of the 1922-1923 

 season a number of mill owners will start the movement to complete the programs for 

 extension and electrification that have been temporarily suspended. 



The example set by Cuba in electrifying her sugar mills has materially affected other 

 cane sugar producing countries. Although there were electrically driven mills in Porto 

 Rico, Mexico and Argentine before the time of Cuba's pioneer electrified mill, the other 

 countries have only recently started well on the road to electrification. The late war 

 has so upset and altered the sources of supply, the markets and even the costs of pro- 

 ducing sugar that the whole world is now on a more competitive basis and it becomes 

 more necessary than before to lower manufacturing costs in order to make acceptable 

 profits. Complete electrification is one of the big factors in accomplishing the desired 

 end. From Sugar Central and Planters News.
