In the initial stage most of the co-operative sugar mills were established with the crushing capacity of 1250 Ton per day. Due to inflation, the production cost kept on increasing and the financial position of sugar mills was badly effected in terms of sales realization. Thus 1250 TCD plant become unviable and it was required to expand the crushing capacity upto 2500 Ton per day on the basis of cane availability. Sugar Federation successfully expanded the crushing capacity of 21 sugar mills from 1250 TCD to 2500 TCD between 1988-89 to 1997-98 in a well planned manner. During Crushing season 1999-2000, 3 sugar mills Belrayan, Sampurna Nagar and Nanauta mills were expanded from 2500 TCD to 5000 TCD.
