(3) Using the RMT-150B rock mechanic test system to study the interparticle breakage of chamber geometry in compressive crushers, those test data were regressed, and the Selection function and Breakage function were got, which provided the basis for calculate and simulate the size reduction of compressive crushers.

Based on advanced breakage theory-interparticle breakage, population balance model and crushing zones' characters, the interparticle breakage process of rock material in chamber of compressive crusher was deeply studied, Combined with the matrix model of rock material breakage, the operating model of rock material interparticle breakage process in chamber of compressive crusher was built up, which opened out the essential causes of interparlicle breakage of compressive crushers and also provided the basis for simulating and optimizing product grain size distribution.

The improved domestic PYB900 cone crusher was regarded as research object, the crushing product grain size clistribution was deeply studied, and the relationship model between product grain size distribution and the key working and structure parameters was accomplished,and the key factors were also quantitatively and qualitatively studied.

(4) Based on the characters of crushing zones, combined with the working character of compressive chamber, the fixed mass theory was put forward, and it was used to study the curved chamber geometry of compressive crushers, and the stroking and awaiting characters of compressive crusher lessened or got rid of. Moreover, the concept of working nip angle was introduced into chamber geometry research, which guaranteed the nipping requirement and improved the machine's working performance.

Based on interparticle breakage, crushing zones' characters, the fixed mass theory and working nip angle demand, the interparticle curved chamber geometry was built up and the new method of interpartcle curved chamber geometry was put forward.
