Cone crusher is a general crushing equipment which is widely used in
industry, such as mine, smelting, building material, road, railway, water
conservancy, chemical industry, etc. Since the cone crusher development in our
country is very slow, also the crusher efficiency is low, it is necessary to
study cone crusher in-depth, as to improve crusher efficiency, save energy and
reduce consumption in broken field. There are several reasons influencing
crusher performance, such as crusher structure, performance parameters and
manipulation parameters. The parameters also have different effect on capacity,
product size, and power consumption. So this requires the establishment of
multi-objective optimization model to optimize cone crusher performance. The
researcher first introduces
basic knowledge and the status quo of performance parameters optimization about
cone crusher, then analyze material
comminution principle and the working principle of cone crusher,
establishes a productivity model based on interparticle breakage and the
movement character of the mass, also studies material breakage process,
establishes a product size model based on population balance model, uses
mathematics model to build optimization model of cone crusher, solves the cone
crusher multi-objective optimization function with major objective solution,
designs the optimization procedure with Matlab software. Finally, we build a three-dimensional
model of domestic-type cone crusher, applies the Matlab optimization
programming on the cone crusher, analyze how rotary speed, eccentricity, close
side setting(CSS) influence cone crusher performance based on the parameter
data and performance data before and after optimization. The cone crusher
performance optimization model and optimization procedure in the paper can be
used to provide reference data in the actual production; also can support the
further research in improving the cone crusher performance.
In view of the solution to the practical problems existing in cone
crusher design, the quantity of rock materiel falling out of the crushing
chamber during once eccentric rotation of the cone is analyzed, the productivity
model for cone crusher with curvilinear chamber geometry is proposed; based on
the population balance theory, the division of crushing chamber is analyzed,
the product size distribution and corresponding calculation method are
researched; combining the empirical model for predicting particle shape with
the size distribution model, the flakiness prediction model based on size
distribution is proposed. The cone crusher optimization model based on quality
control and prediction is built. And the influences of structural and working
parameters of cone crusher on productivity and product quality are analyzed.
All these tasks are useful for future cone crusher optimization strategies
