As the main secondary crushing equipment in the sand and gravel aggregate production line, the cone crusher has been upgraded from the traditional spring cone crusher to the hydraulic cone crusher after years of development and technological innovation. The hydraulic cone crusher has single-cylinder and multi-cylinder series.

Today, we will learn about the advantages of hydraulic cone crusher compared with spring cone crusher. This is also the significance and value of the continuous upgrading of cone crusher.
 

First, let’s look at the differences between spring cone crusher, single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher in terms of structure and principle:
 

Spring Cone Crusher

The spring cone crusher is mainly composed of frame, fixed cone assembly, movable cone assembly, spring mechanism, bowl-shaped shaft frame, transmission, electrical system, lubrication system and other parts in terms of structure.

When working, the motor drives the large bevel gear at the bottom of the eccentric sleeve through the hydraulic coupling and the small bevel gear, causing the eccentric sleeve to rotate, causing the cone to swing and crush the material.

 

Multi-cylinder Hydraulic Cone Crusher

Multi-cylinder hydraulic cone crusher is mainly composed of lower frame, eccentric sleeve, transmission part: transmission shaft small bevel gear sleeve, support sleeve, adjusting ring, moving cone, electrical system, thin oil lubrication system and other parts

During operation, the movable cone performs a rotary pendulum motion driven by the eccentric sleeve, driving the crushing wall to squeeze and grind the material between the crushing wall and the mortar wall. According to the lamination theory, the material is subjected to forces in multiple directions, and is crushed and polished according to its own texture to form stable stone particles. The material that meets the discharge requirements falls from the rotary pendulum gap of the crushing wall, and the rest of the material continues to be crushed until the requirements are met.

 

Single-cylinder Hydraulic Cone Crusher

The single-cylinder hydraulic cone crusher is mainly composed of upper frame, middle frame (medium crushing type), lower frame, moving cone, eccentric sleeve, transmission, hydraulic cylinder, electrical system, thin oil lubrication system and other parts.

When working, the motor drives the horizontal shaft to rotate, and the horizontal shaft drives the eccentric sleeve to rotate through the gear, and then the eccentric sleeve drives the moving cone to swing in a circle, thereby realizing continuous extrusion and crushing of stones.
 

 

The difference in structure and principle leads to great difference in working performance. In the past, spring cone crusher was more commonly used, but with the upgrading of technology, hydraulic cone crusher has gradually replaced spring cone crusher in medium and large sand and gravel aggregate production line projects. So, compared with spring cone crusher, what are the advantages of hydraulic cone crusher?
 

1. Hydraulic cone crusher adopts hydraulic protection and hydraulic cavity clearing, which can realize automatic cavity clearing, convenient maintenance and short downtime, while spring cone crusher needs to be stopped for manual discharge, which is time-consuming and labor-intensive.
 

2. In terms of work efficiency, hydraulic cone crusher can be fully fed, with higher material throughput and processing capacity, and naturally greater output, while spring cone crusher generally cannot be fully fed, which can easily cause machine blockage.
 

3. Hydraulic cone crusher adopts the principle of layered crushing, which can use the crushing effect between stones to reduce the wear on the machine. The finished stone particles are round and full, with good grading, and the needle-like particles are greatly reduced, which solves the problem of more needle-like particles in the finished stone of the previous spring cone crusher.
 

Generally speaking, the performance of hydraulic cone crusher is better than that of spring cone crusher, and its application in mining crushing and sand and gravel processing is becoming more and more common. In terms of price, spring cone crusher is indeed lower than hydraulic cone crusher, but hydraulic cone crusher has high initial investment, low maintenance cost in the later stage, and is more worry-free.
