Crushing Milling Particles

Milling and crushing - LB Officine Meccaniche

MICROTON systems have been designed for dry milling hard materials, such as feldspar, quartz, silica and zirconium and for obtaining particles with a size of less than 10 micron. They are used for the continuous production of micronised powder. The production cycle is fully automated to offer a high production output and low energy consumption.

Crushing Mechanism for Soil Particles

1. Introduction. This is the study to understand the crushing mechanism quantitatively for the development of rod mill device for soil. When a soil sample is examined at a research institute, the soil must first be crushed into fine-grained particles, with a median diameter of less than 2 mm, to satisfy industrial standards.
