Linear Programming using Python

PuLP is a free open source software written in Python. It is used to describe optimisation problems as mathematical models. PuLP can then call any of numerous external LP solvers (CBC, GLPK, CPLEX, Gurobi etc) to solve this model and then use python commands to manipulate and display the solution.

Geometric analysis of cone crusher liner shape

Given the huge range of configurations and operating conditions used in cone crushers, this is a serious issue. Whiten (1972) developed a process model using multiple spline regression which described the effect of crusher geometry with a few parameters. Briggs (1997) developed a simple mathematical model for analysis of crusher geometry.
