AGGREGATES TREATMENT EQUIPMENT

Secondary Jaw Crushers
single toggle
SJC series

Designed for a wide range of applications and high capacity are particularly suitable for crushing any grade of rocks, producing cubic material with low flackiness. The correct conformation of the crushing chamber and the cinematic of the B.S.I. crushers, is a guarantee for high performances lastin long in time. The ease of Use and the reduced maintenance required, make it the ideal machines for the primary crushing of stone materials of every type.

Main construction specifications

- Crushing chamber
carefully designed, with the positioning of the critical section and of the trajectories of the oscillator designed to facilitate the flow of material and, thus, get the maximum production capacity.

- Frame and oscillator
made of deep welded, laser cut, steel sheet. After assembly, they are subjected to a heat stress relief treatment to remove any material stress from the structure.

- Oscillator bearings
housed in special stainless steel sleeves and placed inside the oscillator, instead of directly in the body of the oscillator (most economical choice, adopted by a majority of the builders). This solution ensures, in case of failure of the bearings, a reduced downtime as it is sufficient to replace the respective bushings, and the entire operation is madeon field without the need to rework the oscillator, which would be necessary in case the seats were formed directly in the body of the oscillator, with consequent increases of costs and machine downtime.

- Eccentric shaft
high fatigue resistance steel, supported by wide oversized oscillating roller bearings, which guarantee maximum reliability even in the most demanding applications.

- Fly wheels
made of composite steel and fixed by binders on the eccentric shaft.

- Frame supports
enclosed in special bushes, with grease lubrified labyrinth seals.

- CSS Adjustment
assisted by a hydraulic cylinder attached to the head of the frame, behind the sliding element of the support of the toggle, controlled by a hand pump, equipped with a shut-off valve and is fixed to the housing in an easily accessible position.

- Steel jaws
tooth profiled manganese (standard) or straight profile depending on the application.

- Lateral wedges
built in wear resistant steel 4000 HB, large thickness.

- Toggle
cast iron (for smaller models) or steelwork (for larger models), with interchangeable wear inserts.

- Remote greasing lines
allow the manual (or automatic) lubrication of the bearings with grease, at long intervals of time, from a comfortable and safe position even while the machine is working.
