Single Cylinder Hydraulic Crusher Single cylinder hydraulic cone crusher is widely used in mining, metallurgy,construction, highway, railroad, and waterconservancy, etc. It can break or crush all kinds of medium hard or harder ore for mining, chemical building, materials and other industrial sectors. This kind of machine has the features of big crushing ratio, continuous operating, even granularity, automated hydraulic clearing system, high capacity, simple structure and low operating cost, suited perfectly for middle and fine crushing. Crushing Features: 1.Higher rotating speed and stroke make production capacity which improved 35%-60% than old spring cone crusher; 2.The Max feed size is bigger than other kinds of cone crushers; 3.Better shape of final product than spring cone crusher. Less Needle flake; 4.The design of hydraulic protection and hydraulic cavity clearing improves the automation and reduces the downtime and maintenance time; 5.Auto system of thin oil lubrication makes the life time increased. Working Principle : When the crusher works, the motor drives the small gear; the small gear drives the large gear; the large gear assembly (large gear, large gear rack) drives the eccentric bushing assembly (eccentric steel bush and eccentric bronze bush) and main shaft assembly (main shaft, inner cone, inner cone liner) to revolute within the bronze bush with the center of theoretical verticlal line, while the main shaft assembly can rotate around the main shaft within the eccentric bronze bush as the center line. When the crusher works without load, the eccentric bushing assembly and the main shaft assembly revolutes the large gear. When the materials fall into the crushing cavity, the main shaft assembly (main shaft, inner cone) slowly rotates within the eccentric bronze under the resistance of materials.
