The main factors that influence the quality of the raw meal during its production in a ball mill and storage in stock and homogenisation silos of continuous flow are investigated. A detailed simulation is used, incorporating all the key characteristics of the processes. The quality modules of the raw meal are controlled via robust PID controllers, optimized with the same simulator. The effect o...

Grinding of a high volatile bituminous coal was performed in three comminution devices: Raymond Mill, Rolls Crusher and Ball Mill. The pulverised samples were sieved to obtain four particle size fractions and temperature-programmed combustion (TPC) was used for the evaluation of their combustion behaviour. In addition, three coals of different hardness and rank were mixed in various proportions...

It is well known that the major cause of instability in industrial cement ball mills is the so-called plugging phenomenon. A novel neural network adaptive control scheme for cement milling circuits that is able to fully prevent the mill from plugging is presented. Estimates of the one-step-ahead errors in control signals are calculated through a neural predictive model and used for controller t...

Chemical reactions that take place in a ball mill and the absence of bulk reaction solvent present different safety profiles to stirred solution reactions. Herein, we describe steps researcher may better ensure they have considered some hazards measures emerge minimize risk themselves their colleagues.

This study focuses on the preparation of Ni-plated polystyrene (PS) microspheres (diameter 3.7–4.5 μm). These Ni-plated PS microspheres have core–shell structures that were designed and prepared using an organic polymer core (PS with 3-(trimethoxysilyl) propyl methacrylate (TSPM)) and an inorganic metal (Ni) plated shell. The polymer microspheres were synthesized by dispersion copolymerization,...

The high demand for carbon composite in many industries results in an increase in the embodied energy footprint of carbon composites. Recycling technologies for carbon composites are being developed to reduce the embodied energy footprint of the material. The purpose of this research is to analyze and estimate the specific energy consumption from mechanical recycling method, specifically a ball...
