TL;DR: In this article, the influence of grinding conditions on the production of fine particles and the width of the particle size distribution produced during ball mill grinding was investigated, and the grinding experiments were carried out varying the grinding ball diameter under dry and wet conditions.
115 citations
TL;DR: In this paper, the authors investigated the effects of feed size and ball diameter on the grinding rate constant of the materials used when the mass of balls, mass of feed, and the mill's rotational speed were constant.
57 citations
TL;DR: In this article, a tumbling ball mill was used to measure a selection function for five solid materials and the effects of a grinding ball diameter and a feed particle size on the grinding rate constant of the materials were investigated.

TL;DR: In this article, the authors presented various Laws of comminution energy including Rittinger's law Kick's law Bond's law, and Holmes's law and showed that the energy required for fine grinding increases with a decrease in feed or produced particle size.
Abstract: Publisher Summary This chapter highlights comminution energy and evaluation in fine grinding. The purposes for comminution are to liberate minerals for concentration processes, to reduce the size, to increase the surface area, and to free the useful materials from their matrices. Comminution is an old mechanical unit operation for size reduction of solid materials and an important operation in the field of mineral processing, the ceramic industry, the electronics industry and so on. The energy efficiency of comminution is very low and the energy required for comminution increases with a decrease in feed or produced particle size. Research and development to find energy saving and the energy required in comminution processes have been performed. In design, operation and control of comminution processes, it is necessary to evaluate the comminution energy of solid materials. In general, the comminution energy (i.e., the size reduction energy) is expressed as a function of the particle size of feed and product. In addition, the chapter also presented various Laws of comminution energy including Rittinger's law Kick's law Bond's law, and Holmes's law.

TL;DR: In this article, a wet-milling treatment was used to activate coal fly ash and promote its sustainable utilization. But the results showed that the pozzolanic reactivity of fly ash is greatly improved after wetmilling, as high as 140% at 60 days.

TL;DR: Autoclaved aerated concrete waste (AACW) is a common low-strength cement-based construction and demolition waste, which is currently disposed by landfills and hard to be directly used as supplementary cementitious material as discussed by the authors.
102 citations
TL;DR: In this paper, the physical-chemical properties of micro-lithium slag (micro-LS) were characterized comprehensively, and its compressive strength at 16h, 1day, and 28 days was measured.

TL;DR: In this article, the physicochemical properties of both dry and wet milled boron particles with sub-micron sizes were investigated, and it was found that the size distribution of borons grinded under dry milling condition was much broader than that under wet milling condition, and the size reduction rate in the dry process was faster than that in the wet process.
