Comminution of Wood: Single‐Particle Breakage
نویسندگان
چکیده
An essential element for the sustainable use of renewable resources is an efficient comminution process. For processes, detailed knowledge fracturing processes necessary. Therefore, single-particle under impact stress was investigated, and influence moisture content particle size in beech wood described. The extent applicability existing models to wood, modeling breakage probability function brittle materials, investigated.

Laboratory studies in comminution: Part VI The specific rate of breakage for rod and ball milling of quartz
The influence of feed size and pulp density on the specific rate of breakage of quartz was investigated. Plots of log fraction of feed remaining within the feed size interval against grinding time allowed the application of the first order grinding model to be examined. Substantial non-linearities were observed for all feed sizes due to environmental and material factors. For feed sizes above 1...
متن کاملComplex networks in confined comminution.
The physical process of confined comminution is investigated within the framework of complex networks. We first characterize the topology of the unweighted contact networks as generated by the confined comminution process. We find this process gives rise to an ultimate contact network which exhibits a scale-free degree distribution and small world properties. In particular, if viewed in the con...

Nacrtak An experiment on comminution of logging residues with a tub grinder was carried out in order to calculate the productivity and procurement cost of wood chips. At the investigated site, the tub grinder had a hammer mill crusher at the bottom of the tub, and a grapple loader and a bucket loader worked as auxiliary machines for the grinder. As a result, the productivity of the tub grinder ...

OBJECTIVE This study aimed to investigate the impact on nonunion of the extent of comminution and postoperative displacement in patients surgically treated for subtrochanteric fractures. METHODS From 2008 to 2013, 44 patients with subtrochanteric fractures underwent surgery and follow-up. Retrospective data collection showed that it had 32 male and 12 female. Their mean age was 45 years. The ...
متن کاملSelection of Comminution Circuits for Improved Efficiency
This paper examines the design of comminution circuits and the issues that impact on comminution circuit efficiency. Circuit efficiency is discussed, principally from the perspective of power efficiency. However, operating efficiency, maintenance efficiency, capital expenditure and return on investment are often the key efficiency factors in project development outweighing power efficiency cons...
