Particle Size Reduction

 · An important consideration in particle size reduction is step grinding. Essentially, this is pre-grinding. The idea is to reduce the work of the machine by reducing the work it has to do on the product. In the case of pulverizers, it is highly recommended to do this for maximum efficiency. Initial investment costs may seem high, but decreasing

Optimizing the Particle Size Reduction Process

16/01/2022 · To begin to optimize the particle size reduction process, we must first ask ourselves a few questions. .2 mm Slot Screen = Maximum Particles Size < 200 um; MILL SPEED: Mill speed should be 2150 feet per minute, or 12 meters per second. This can be adjusted up or down for achieving ultra fine nano grinds, or to not over grind a shear


During size reduction energy is supplied to the equipment (mill). Very small amount of energy (less than 2%) actually produce size reduction. Rest of the energy is dissipated (wasted) in: (i) Elastic deformation of particles. (ii) Transport of material within the milling chamber. (iii) Friction between the particles.

Particle Size Reduction

Reduction of particle size of a solid can be achieved by various means such as rotor stator inline homogenizer, bead mill, etc. leading to an increase in surface area with enhanced dissolution. For particle size reduction, this same rotor/stator action will ensure the rapid and uniform milling of both solid and semi – solid materials into either solution or fine suspension.
