CHAPTER 20: SIZE REDUCTION – EQUIPMENT FOR SIZE
• Best example – Break and reduction rolls of wheat milling • Disintegrators are toothed roll crushers in which the corrugated rolls are rotating at different speeds • Size reduction is by compression, impact and shear and not by compression In general, compression is used for the coarse reduction of hard solids (to yields relatively few fines), impact gives coarse, medium or fine products, attrition gives very fine products from soft, nonabrasive materials and cutting produces a product of a definite particle size and sometimes a definite shape, with few or no finesCPE: Lesson 13 Principle of Size ReductionTable 41 Applications of size reduction equipment Equipment Type of producta Finenessb 123 45a bc d Slicers * * * * Dicers * * * * Shredders **** Bowl choppers * * * * * Precrushers * * * * Hammer mills * * * * * * Fine impact mills * * * * * * Classifier mills * * * Air jets mills * * * * Ball mills * * Disc mills * * * Roller mills * * * * * Pulpers * * * a4 Size reduction UB

A colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins High speed rotation applies fluid shear stress, inducing the breakdown of agglomerates The speed of the rotation can also be reduced during mixing to induce a smoother impact and avoid material degradation while still producing enough Bond’s law has been found to apply well to a variety of materials undergoing coarse, intermediate and fine grinding 435 SizeReduction Equipment a) Roller mill A common type of roller mill consists of two cylindrical steel rolls, mounted on horizontal axes and rotating towards each other The particles of feed are directed between the rollers from above They are nipped and pulled Food Engineering: Lesson 43 SIZE REDUCTIONFor coarse reduction of hard solids, use ? a Impact b Attrition c Compression d Cutting ANSWER: See Answer MCQs: Vacuum is applied in zone, in case of a general type continuous rotary drum vacuum filter?

03/04/2015 Attrition – It is a term applied to the reduction of materials by scrubbing it between two hard surfaces Hammer mills operate with close clearances between the hammers and the screen bars and materials reduce by attrition combined with shear and impact reduction Though attrition consumes more power and exacts heavier wear on hammers and screen bars, it is Coarse Aggregates Coarse aggregates are irregular broken stones or naturally occurring round gravels that are used to make concrete, coarse aggregates for structural concrete consist of broken stones of hard rock like granite and limestone Coarse Aggregates: Types, Properites Applications01/01/2019 The hammer mill is suitable for hard materials, although, because a large amount of fines is produced, it is advisable to employ positive pressure lubrication to the bearings in order to prevent the entry of dust The size of the product is regulated by the size of the screen and the speed of rotationParticle Size Reduction and Enlargement ScienceDirect
