ATM INDUSTRY ACC series Single-Cylinder Hydraulic Cone Crusher adopted and improved the original design, technology & manufacturing process of international famous crusher brand, perfectly interchangeable. Reliable performance – ACC owns simple and advanced designs, such as crusher interior anti-dust protection by seal ring, replaceable sleeve and inner head nut to protect main shaft, and adjustable Gear backlash etc., all of which ensure reliable performance and robust structure; Independent countershaft assembly design – The countershaft bearings of ACC are lubricated by an independent circulatory system. A flow of oil is bled off from the main lubrication system and is pumped to the oil inlet in the top of the countershaft housing; Hydraulic setting adjustment – The robust hydraulic jack will support the main shaft and adjust its position. By moving the main shaft up and down, the discharge setting can be changed and the size of the crushed material can thereby be changed, also, the setting adjustment system is designed to compensate for mantle and concave ring wear.
