IT IS APPLICABLE FOR ALL STUDENTS ADMITTED IN THE YEAR 2011 2012-2013 (ANNA UNIVERSITY CHENNAI,TRICHY,MADURAI, TIRUNELVELI,COIMBATORE), 2008 REGULATION OF ANNA UNIVERSITY CHENNAI AND STUDENTS ADMITTED IN ANNA UNIVERSITY CHENNAI DURING 2009
CH 2255 MECHANICAL OPERATIONS L T P C
3 0 0 3
AIM
To impart knowledge in separating solids from solids, solids from liquids, reduction of
size, and mixing of solid, solid, liquid – liquid components
OBJECTIVES
The students will be in a position to understand that the industrial processes contain a
coordinated series of separation operations and they will be in a position to decide the
best process needed for a particular process industry.
UNIT I PARTICLE CHARACTERISTICS AND SIZE ANALYSIS 7
General characteristics of solids, their behaviour under different external forces,
agglomeration, techniques for size analysis.
UNIT II SIZE REDUCTION 8
Laws of size reduction, classification of equipment, methods of size reduction,
disintegration, preparation of colloids.
36
UNIT III MECHANICAL SEPARATIONS 9
Screening and Screening equipment, effectiveness of screens, gravity settling,
sedimentation, thickening, centrifugal separation, impingement methods, industrial dust
removing equipment with special reference to electrostatic and magnetic separators,
heavy media separations, floatation.
UNIT IV FILTRATION 7
Theory of filtration, Batch and continuous filters, centrifuges, membrane and ultra
filtration.
UNIT V MIXING AND AGITATION 7
Equipment for blending and kneading, dispersion, power for agitation, correlations.
UNIT VI STORAGE AND CONVEYING OF SOLIDS 7
Conveyors, Elevators, Pneumatic conveying, Different methods for storage of solids.
TOTAL : 45 PERIODS
