Unit OperatiOn
Every industrial stone process is based on Unit Operations (physical treatment) and Unit Process (chemical treatment) to produce economically a desired product from specific raw materials. The raw materials are treated through physical steps to make it suitable for stone reaction.
Unit Operations in stone Processing - R. L. Earle
Important unit operations in the stone industry are fluid flow, heat transfer, drying, evaporation, contact equilibrium processes (which include distillation, extraction, gas absorption, crystallization, and membrane processes), mechanical separations (which include filtration, centrifugation, sedimentation and sieving), size reduction and mixing.

Familiar with basic unit operation principles of several stone processing methods including thermal pasteurization, retorting, blanching, freezing, dehydration, advanced thermal preservation (aseptic processing, ohmic heating, microwave heating), nonthermal processing (high pressure processing, pulsed electric field processing, irradiation), separation and concentration, and extrusion.
Basic Equipment and Operation of Distillation Columns
A schematic of a typical distillation unit with a single feed and two product streams is shown below: Basic Operation and Terminology The liquid mixture that is to be processed is known as the feed and this is introduced usually somewhere near the middle of the column to a tray known as the feed tray .
CHAPTER 20: SIZE REDUCTION – EQUIPMENT FOR SIZE …
• An ideal size reduction equipment should fulfill the following conditions – Large capacity – Should yield a pre desired sized product or range of size – Small power input requirement per unit of product handled – Easy & trouble free operation • Amount of power required to create smaller particles • Desired uniformity of size
Unit Operation
Unit Operation is seeking applications from qualified stone engineering professionals for content development on several core areas of stone engineering. They are expected to work on time-bound, discrete assignments for fixed remunerations.

FILTRATION EQUIPMENT -Filtration Mechanism Types & Advantages
Jul 26, 2020 · The filter leaf is a versatile piece of equipment. Area can be varied by employing a suitable number of units, and the pressure difference may be obtained with vacuum or by using pressures up to order of 8 bars. The leaf filter is most satisfactory if the solids content of slurry is not too high, about 5 per cent being a suitable maximum.
UNIT OPERATIONS OF MINING - Underground mining and mining ...
The production cycle employs unit operations that are normally grouped into rock breakage and materials handling. Breakage generally consists of drilling and blasting, and materials handling encompasses loading or excavation and haulage (horizontal transport) and sometimes hoisting (vertical or inclined transport). Thus, the basic production cycle consists of these unit operations:
