Spring Cone Crusher

Spring Cone Crusher can be used for secondary and fine crushing of hard and medium-hard mineral stones, such as iron ore, copper ore, quartz, granite, basalt, dolerite, etc. The spring safety system of the spring cone crusher serves as an overloading protection system that keeps the cone crusher from metal damage. The dry oil and water sealing form of the safety system is adopted to make plaster powder and engine oil separate to guarantee reliable performance.

Product features
Compared with jaw crushers, the spring cone crusher has the advantage of low operation costs, high productivity, easy adjustment, and stable structure. Cone Crusher can be used for secondary and fine crushing of hard and medium-hard mineral stones.
Stable Performance
Increased eccentricity and processing capacity. Accelerating speed, increasing power and improving crushing fineness.
Quality Assurance

Raise the center of the moving cone pendulum and optimize the cavity design. Thickening of liner and prolonging service life.

Optimal Design
The hydraulic motor replaces the hydraulic push rod device, the discharge port is adjusted continuously and accurately, and the fixed cone assembly can be dismantled within 10 minutes.
Differentiated design

Cone crusher is an advanced crusher with high power, high crushing ratio, and high productivity. Spring is not only a safety device but also affects the crushing force.

PYB Series Cone Crushers are used to improve productivity, increase cubical product, and reduce downtime and maintenance costs. The standard type of spring cone crusher is applied to medium crushing, and the short head type is to fine crushing.
Applicable materials
Stone crusher is used for crushing over 120 kinds of rocks, such as limestone, granite, quartz, basalt, river stone, gold ore, iron ore, coal, gravel, aggregate, etc. Different final output sizes could meet your different needs.

What is the structure of the spring cone crusher?

The structure of the spring cone crusher is mainly composed of a frame, fixed cone, movable cone assembly, spring mechanism, bowl, and transmission shaft frame.

Spring Cone Crusher Working Principle  

The spring cone crusher crushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficient than a jaw crusher. The movable cone is supported by a spherical bearing and fixed on a hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and erect shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by a horizontal shaft and fabricated gear, and the wheel of the conveyor belt is driven by a motor through v-belts. The lower part of the vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are ground into pieces, when the cone leaves, ground materials are discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting the setting to adjust the width of the discharge hole, consequently, the output size is determined.
