Introduction to the Working Principle of Spring Cone Crusher

What is a Spring Cone Crusher?

A spring cone crusher is a vital piece of machinery utilized in mining, construction, and metallurgical industries for crushing rocks and ores. Its efficiency, reliability, and performance make it a favored choice among many professionals in these fields. This article provides an in-depth "Introduction to the working principle of spring cone crusher," explaining its functionality and significance.

Understanding the Working Principle of Spring Cone Crusher

1. Structure

The spring cone crusher comprises several essential components, including the mainframe, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs, and a hydraulic pressure station for adjusting discharge size. This robust construction ensures durability and reliability.

2. Working Mechanism

The working principle of a spring cone crusher is based on the spontaneous movements of the movable cone and the fixed cone. Here’s a step-by-step guide demonstrating this principle:

a) Material Entry

• Raw materials are fed into the crusher through the feed opening and are gradually crushed by the gyrating cone.

b) Crushing Process

• The motor drives the eccentric shaft shell to turn around through a horizontal axle and a pair of bevel gear, while the crushing cone makes a rotary movement.
• The swing of the crushing cone is driven by the eccentric sleeve, which rotates around the central axis. The cone moves closer to and then away from the fixed cone, causing materials to be crushed due to the compressive forces applied.

c) Size Adjustment

• The spring system plays a critical role in the crusher's ability to adjust the size of the crushed particles. The tightness of the springs can be changed to determine the crusher's output size. When hard materials enter the crushing chamber, the spring provides an overload protection mechanism, allowing the movable cone to increase its distance from the fixed cone, thus avoiding damage to the machine.

d) Discharge

• After crushing, materials are ejected through the opening at the bottom of the crushing chamber, ensuring a continuous, efficient process.

3. Advantages of Spring Cone Crusher

a) High Efficiency

• The spring system aids in achieving high efficiency by providing consistent and powerful crushing action.

b) Durable and Robust Design

• The solid construction materials and design extend the crusher's lifespan and reliability.

c) Adjustable Settings

• The spring system allows for easy adjustment of the particle size, giving flexibility for different applications.

d) Protection from Overloading

• The springs act as a failsafe mechanism protecting the crusher from damage when processing hard or uncrushable materials.

Applications of Spring Cone Crushers

Spring cone crushers are typically used for secondary and fine crushing processes in various industries. Their primary applications include:

• Mining & Mineral Processing
  • Effective in reducing the size of ore and stones.
