ball mill simulation in wet grinding using a tumbling mill and its correlation to grinding rate
Powder Technology, 2004Co-Authors: Hiroto Mori, Junya Kano, Fumio SaitoAbstract:A method for simulating the motion of balls in tumbling ball mill under wet condition is investigated. The simulation method is based on the three-dimensional discrete element method (DEM) and takes into account the effects of the presence of suspension, i.e., drag force and buoyancy. The impact energy on balls' collision, which enables us to provide useful information for predicting the grinding rate, was calculated from the simulation work. Actual ball motion in the suspension in the mill was observed through a transparent mill lid made of Acrylic Acid Resin at different solid concentrations and the suspension was made of water with powder samples such as gibbsite, limestone and talc. Grinding tests of the gibbsite sample using two laboratory tumbling ball mills made of stainless steel and using alumina with balls made of steel, alumina and glass were conducted and the grinding rate was determined by measuring the 50% particle size of the product. The specific impact energy calculated from the simulation work correlates well with the grinding rate of the sample, irrespective of the grinding conditions, so that the energy is the key factor controlling the grinding phenomena in wet milling.

permeation tests on tianluoshan relic soils with methyl Acrylic Acid Resin
Advanced Materials Research, 2013Co-Authors: Pei Hang Chen, Xin Jun Chai, Jin He Gao, Yu Jiao WangAbstract:Tianluoshan relic sites is a typical earthen sites located at moisture circumstances, where craking, chalking, flaking and mould are the main geological diseases after excavation. For public exhibition and long-term preservation purpose, chemical stabilization were required. In this study, the potential application of methyl Acrylic Acid Resin for solidification of Tianluoshan relic soils were evaluated by a series of laboratory permeation tests. The main considered influence factors include: dry density, initial water content and degree of saturation. The results show that the permeation effect of methyl Acrylic Acid Resin were greatly related with dry density and initial water content of the earthen soils, the practical application guidance are also presented.

unconfined compression strength of tianluoshan relic soils solidified by methyl Acrylic Acid Resin
Advanced Materials Research, 2012Co-Authors: Xin Jun Chai, Yan Sheng Gao, Chen Xi RaoAbstract:The consolidation and conservation of earthen sites is one of the difficult problems at home and abroad. Tianluoshan relic sites is a typical earthen sites located at humid circumstances. For public exhibitions and research purposes, a few chemical grouts were recommended for solidification and conservation of the excavated historical heritage sites. In this paper, the potential application of methyl Acrylic Acid Resin for strengthening Tianluoshan relic soils were evaluated by a series of unconfined compression tests considering the influence of curing condition, curing time, and water content. The results showed that methyl Acrylic Acid Resin can effectively improve the strength of Tianluoshan relic soils.
