The slurry contains around 38-40% water that is stored in storage tanks and kept ready for the rotary kiln. ... where decomposition of lime stone takes place. The remaining material is in the form ...
Grinding: The next step in the sugar manufacturing process is the grinding process. This is where the raw sugar cane pieces are ground into a fine powder-like consistency. This is done using a grinding machine. The grinding process helps to break down the individual pieces of cane, allowing for better extraction of the sugar content. …
This process provides a new and fresh layer of abrasives for removal of material. This process is known as Dressing of grinding wheel and the whole process takes 15 to 20 minutes to operate. The life of the grinding wheel is described as the time period between two successive dressings.
As for the optimized process, lime was added during grinding, and the pulp was aerated before flotation. In the aeration stage, the air blowing switch was opened, and the air flow was controlled at 3.5 L/min, then the slurry was aerated at the set time. Afterward, collector and ing agent were introduced subsequently. The function time …
