Slurry flow in mills: grateonly discharge mechanism (Part1)
2003年7月1日 If the grate provides a high resistance to flow of slurry, then the mill will fill with an excessive amount of slurry to a level past where efficient grinding occurs, and the mill will “go off the grind” (Austin et al, 1984)Moys (1986) supported this view and stated that an excessive buildup of slurry would seriously affect autogenous mills as a large volume of dense slurry Abstract: The particle size distribution of ball mill grinding products is an important production index of the grinding operation, and due to its multivariate strong coupling and nonlinearity in the operation process, it leads to difficulties in achieving optimal control of the discharge particle size distribution To this end, a reinforcement learningbased optimal control method is proposed Reinforcement learning based ball mill discharge size distribution A vertical roller mill, also known as a vertical grinding mill or vertical mill, is a comprehensive grinding equipment integrating crushing, drying, grinding, grading, and conveying Vertical grinding mills can be widely used in electric power, Energysaving and Efficient Vertical Roller Mill Fote 2018年1月1日 Batch dry grinding of –335+17 mm and –17+06 mm feed fractions of anthracite and lignite was studied in order to Fine grinding of lignite in a ball mill was shown to be nonlinear in Kinetics and sub sieve morphology of ball mill grinding for
