The results are shown in Figure 3-17. It is seen that for a reduction ratio of 1.32, the relative efficiency of crushing a multi-layer of particles is 72%. Note that crushing ratios in a ball mill are not well defined, but are believed to range up to 1.5 or even 2.0.

Crushing Of Coal And Calculation Of Size Reduction Efficiency Feb 25, Crushing efficiency has been defined in the literature from the power consumption point of view. But while operating a process plant, it is important that the crushing efficiency is defined in terms of the requirement of subsequent process.

Principles Of Size Reduction By Crushing. A material consisting originally of 20 mm particle crushed to an average size of 5 mm and required 30 kjkg for this size reduction determine the energy required to crush the material from 20 mm to 3 mm assuming a rittingers law b kicks law and c bonds law solution a applying rittingers law as expressed by equation 410.

10/7 · The Shredder Unit can be made with crusher and separator units according to customer demand. It is possible to reduce the grain size up to 1 mm if the shredder designed with the crusher. PCBs, which are electronic waste, is approximately 40×40 cm in size. They feed directly into the shredder and the resulting product size is in the range of 25

10+ Formulas on Size Reduction Laws Calculators Area of Feed in Terms of Crushing Efficiency Area of Feed = Area of Product- ( (Crushing Efficiency*Energy Absorbed By Unit Mass Of Feed)/ (Surface Energy per Unit Area)) Go Area of Product giving Crushing Efficiency

Cutting and chopping are size reduction operations based on shearing through the use of sharp-edged moving elements (knives, blades). The term 'cutting' is usually reserved for operations resulting in particles with fairly regular geometric forms (cubes, juliennes, slices), while the term 'chopping' is applied mainly to random cutting.
