Particle Size Conversion Chart

Mesh size refers to the number of openings in one inch of screen. For example, a 4-mesh screen means that there are four squares within one inch of the screen. As the mesh size increases, the particle size decreases to create a finer material. Mesh size is not a precise measurement of particle size, but it is a fair estimation.Get price

Size reduction in feed technology and methods for

Roller milling tends to produce a more uniform particle size distribution (PSD) and consumes less energy, whilst hammer mills have a greater grinding capacity and a higher reduction ratio compared to roller mill. The multicracker system, a more recently developed technology, can be considered cost-effective and ensures grinding capacity. Get price
