Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the 'Primary Crusher'. Cone crushers are typically used for 2 nd, 3 rd & 4 th stage crushing steps (although not always).
13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.
Importantly, different types of rock require different levels of force during primary rock crushing in order to achieve desirable results. Soft rocks like limestone …

It is important that the rotor ha sufficient thermal mass to start the load inertia. With the soft starter, set parameter 1 to equal the rated current of the motor, parameter 2 to 400%, parameter 3 to 400% and parameter 4 to 1. If the acceleration is too slow, increase 2 to 450% and try again. We have started many high inertia rock crushers and ...
Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
This publication supplies the minimum information needed to select an enclosed SMC™ soft starter for applications with low star ting torque requirements.
