mineral cone crusher hydraulic daigram

Its structure is shown in Fig. 1. It was developed by Allis-Chalmers (AC) Company in the 1940s, so it is usually called AC cone crusher. Single-cylinder hydraulic cone crusher has the same main structure and operating principle as spring cone crusher, but it has a hydraulic device at the connection between sup-port sleeve and frame.

For this reason, state of the art cone crusher control technology in the mineral processing industry seems to be lagging; the crushing stage is overlooked because it is only a part of a mining plant, and variations in crusher performance are rarely a cause for concern, unless the implications are catastrophic (Bearman and Briggs, 1998).

The main shaft of multicylinder hydraulic cone crusher is fixed on the main frame-work and has great eccentric torque, and the rotat-ing speed of the eccentric bushing is far faster than that of spring cone crusher. This will increase the impact force and crushing frequency of the crushing cone and enhance production capacity.

A mechanistic modular model for particle flow, size reduction, and pressure prediction in cone crushers was developed in Evertsson (2000, 1995), Evertsson and Bearman (1997), Evertsson (1998, 1999a,b). The authors defined the size reduction by consecutive events, each with its own breakage and selection function.

In Itävuo et al. (2011), using simulations, the authors demonstrated that simple PID control of a gyratory cone crusher can cancel all reasonable effects of process disturbances, although full-scale tests are needed to validate the findings.

It is also common practice in the literature to divide the length of the cone crusher into several crushing zones that have their own dynamics; however, their input and output streams are connected, as observed in Herbst and Oblad (1985), Atta et al. (2014), Evertsson (2000).
