The chamber is again formed by a concave and a mantle, with the mantle gyrating on an eccentric sleeve. The difference is that the mantle is supported on the piston of a hydraulic cylinder: changing the oil volume in the cylinder raises or lowers the mantle as a whole, which changes the closed-side setting.
If uncrushable material enters, hydraulic pressure is momentarily exceeded, the mantle drops and opens a passage for the object to pass, after which the system resets automatically. To clear the chamber, the cylinder lifts the mantle and discharges everything inside, avoiding the safety risk of manual clearing.
Yes. The hydraulic pump lifts the mantle, the chamber opens and the material inside discharges under gravity. The whole sequence runs from the control cabinet — the operator just presses a button, unlike a spring cone where the chamber may need manual attention.
Watch three things: oil level and condition, oil temperature and system pressure. Check oil cleanliness every 2,000 hours and change filters on the manufacturer's interval. Persistently high oil temperature usually means a fouled cooler or high ambient temperature — clean the cooler or increase cooling capacity.
A single-cylinder design uses one cylinder for setting, protection and clearing — simpler, with fewer maintenance points, and adequate for most medium-to-large aggregate lines. A multi-cylinder design spreads several cylinders around the frame, giving greater crushing and clamping force and a more stable setting — better for very hard rock and very large concentrators. Choose on hardness, scale and budget.
