Disk Mills are suitable for fine grinding of medium particle sizes of soft to hard, brittle and temperature-sensitive solids. The material to be ground is comminuted by pressure and shearing action between two counteracting grinding disks with coarse interlocking teeth.

Reactors are classified as pressure vessels, and as such the pressure vessel design methods can be used to estimate wall thickness and thus determine capital cost. Additional costs come from reactor internals or other equipment. Jacketed stirred-tank reactors require more in depth analysis than that provided by pressure vessel design.

Under ideal working conditions, Raymond Mill consumes less energy than other ordinary grinding mills. For example, the MTM Medium-speed Grinding Mill only consumes 1.02kW/h when yielding a ton of materials and 1.48kW/h when feeding a ton of materials. Its electricity consumption is lower than that of ball mill at the same level by over 60%.

13.1.1.2 Medium-speed mill. Medium-speed mills are smaller than low-speed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75–225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.

Due to the high rigidity possible, improved accuracy with movements of 0.1 microns is possible. Due to the oil film, the stick-slip phenomenon that is ever-present in roller contact guideways is also eliminated due to there being no physical contact between carriage and rail. This further improves accuracy by ensuring smooth motion at any speed.
