Size Reduction Equipments

 · Size Reduction Equipments. In the industry, we frequently need to reduce the size of a certain particle. For different purposes, we use different methods and machines for size reduction. Solids are broken down in different ways but mainly four methods are used like 1) Compression, 2) Impact, 3) Attrition or Rubbing, and 4) Cutting.

A. Recommended peripheral speed for the turbine agitator is 200-250 metres/minute B. Pitched blade turbine agitator gives only radial flow with complete absence of the axial flow C. Generally, the diameter of the agitator is kept between l/3rd to l/6th of the tank

Stirrer Speed

Under normal fermenter operating conditions, increasing the stirrer speed and gas flow rate improves the value of k L a.Typical data for k L a in Newtonian fluids of varying viscosity are shown in Figure 10.10.The strong dependence of k L a on stirrer speed is evident from Figure 10.10(a): in this system, doubling the stirrer speed N i resulted in an average 4.6-fold …
