In wet milling, the addition of surfactants (e.g. sodium lauryl sulfate and polysorbate 80) and polymers (e.g. hydroxypropylmethyl cellulose, hydroxypropyl cellulose, polyvinylpyrrolidone and poloxamer), singly or in combination, helps to minimize the agglomeration of suspended particles via electrostatic and steric mechanisms.


Which Grinding Wheel Should I Choose? | Norton

A grinding wheel is a precision tool with thousands of cutting points on its surface - abrasive grains that are held in place by a bond matrix (hence these are known as bonded abrasives) and separated by pores.. These pores are hollow spaces between abrasive grains and the bond, which help with the clearance of discarded metal chips in the grinding process.
