Size reduction - SlideShare

29-08-2018  Size reduction is a process of reducing large solid unit masses into small unit masses, coarse particles or fine particles. Size reduction process is also termed as Comminution/Diminution/Pulverizations. Solid pieces of food is reduced by the application of grinding, compression or impact forces. In many food processes it is frequently

size reduction - SlideShare

13-03-2015  OBJECTIVES OF SIZE REDUCTION In the materials processing industry, size reduction or comminution is usually carried out in order to: Increase the surface area because, in most reactions involving solid particles, the rate of reactions is directly proportional to the area of contact with a second phase. Break a material into very small particles in order to separate the valuable amongst the two

size reduction.pptx Mill (Grinding) Physics ...

Tumbling mills (Rod mill) In a rod mill, much of the reduction is done by rolling compression and by attrition as the rods slide downward and roll over one another. The grinding rods are usually steel, 25 to 125 mm (1 to 5 in.) in diameter, with several sizes present at all times in any given mill. The rods extend the full length of the mill. Rod mills are intermediate grinders, reducing a 20-mm (3/4 in.) feed to perhaps I0-mesh, often preparing the product from a crusher for final reduction ...

It is expressed in terms of q, the reduction ratio where q = L 1 /L 2 .When a uniform particle is crushed, after the first crushing the size of the particles produced will vary a great deal from relatively coarse to fine and even to dust.As the grinding continues, the coarser particles will be further reduced but there will be less change in the size of the fine particles. The surface area of a fine particulate material is large
