The development and application of the new comminution systems has been recognised to be of paramount importance due to the inefficiency of conventional comminution devices like tumbling ball mills. 2.1 Roller mills 2.1.1 High pressure roller mill (HPRM) The HPRM has been applied to the existing comminution flow sheets for some brittle
Comminution in the mineral processing plant, or "mill", takes place as a sequence of crushing and grinding processes. Crushing reduces the particle size of run-of-mine ore to such a level that grinding can be carried out until the mineral and gangue are …
Nowadays, with the increasing depletion of high grade and coarse-grained ores, the trend is towards the extraction of low-grade ores [1].This can have two consequences for the minerals industry; first to process larger tonnages of mineral raw material and second to grind the raw materials to finer sizes [2], which in turn leads to higher energy consumption.
Biomass entrained-flow gasification is one of the most promising conversion technologies for biomass utilization, characterized by high conversion efficiency and …
Comminution, the process of breaking down solid waste material into smaller particles, plays a critical role in wastewater treatment. Optimizing this process is essential for enhancing performance and reducing energy consumption.
Biomass entrained-flow gasification is one of the most promising conversion technologies for biomass utilization, characterized by high conversion efficiency and environmental friendliness. As a booming technology, the selection of particle size in biomass entrained-flow gasification has been a key issue of concern but has not yet been resolved.
Comminutors (a.k.a. grinders, macerators) are used to reduce the particle size of wastewater solids. The terms "Sewage Grinder" and "Comminutor" are …
By examining the comminution energy consumption and the resulting particle properties (such as size, shape, flowability, and bulk characteristics), this work provides critical insights into particle size selection for optimizing biomass gasification processes.
Investigations are presented on the effects of grain-size composition on the flow resistance of debris flows via laboratory experiments with bidisperse granular materials.

Smaller particles have more surface area and their bulk density, porosity, flow, and solubility considerably vary from large particles. All these properties will influence the formation, packaging, and processing of dosage forms. Thus, comminution is considered a key step in manufacturing of pharmaceutical products.
