샌드빅 QJ 341+

We offer for sale a reliable, well-proven Sandvik QJ341+ mobile jaw crusher. The machine is equipped with an independent double-deck pre-screen positioned before the crusher inlet, ensuring effective removal of fines. This results in higher machine performance, reduced wear of the crushing jaws and lower fuel consumption. Another advantage of this machine is the automatic material feed into the crusher, eliminating the need for operator intervention. The crusher closed side setting (CSS) is fully hydraulically adjustable via the control panel or remote control. The crusher can be started under full load or with a fully filled crushing chamber and features a reverse crushing function to release jammed or problematic material, such as asphalt.
