Key issues and challenges in spice grinding ScienceDirect

Grinding is an ageold technique of particle size reduction to produce powders that can be used as intermediate or end products. Grinding aims to reduce the size of the particle by mechanical means such as impact, compression, shear, and cutting (Sahay and Singh, 1996).Hammer mill, plate mill, ball mill, pin mill, roller mill are commonly used grinding equipment for spice (Balasubramanian et ...

Effect of Water Density on Grinding Mill 911 Metallurgist

Effect of Water Density on Grinding Mill 911 Metallurgist

Once the ore has been mixed with water and is in a slurry form, it will flow along with the water. The bad side of the water is that it takes up space. The more water that is added, the faster the ore will go through the mill. This means the time it has to be ground will be reduced and a poor grind will result.
