Why Is Cone Crusher Machine Recommended For Crushing Granite?

Granite has a Mohs hardness of 6-7, a compressive strength of 100-300MPa, is wear-resistant and corrosion-resistant, and is much harder than limestone. Using ordinary Stone Crusher Machine will cause great loss to wear-resistant parts.

Here VEST Machinery recommends that you use a Cone Crushers Machine for the following reasons:

♦♦ Cone Crushers Is Suitable For Processing High-hardness Materials

1. Granite characteristics: Granite is a high-hardness rock (Mohs hardness 6-7), with high compressive strength (usually more than 200MPa), and has extremely high requirements for the wear resistance and strength of the crushing equipment.

2. Cone crusher structural advantages: Cone crusher adopts solid cast steel body and high manganese steel wear-resistant liner, which can withstand high-strength impact and wear of granite and is suitable for long-term crushing of hard rock.

♦♦ Rock Cone Crusher Adopts the Principle of Layered Crushing, and The Particle Shape Is Uniform

1. Laminated crushing: Through the extrusion and shearing action between the moving cone and the fixed cone, the “stone hitting stone” crushing is achieved instead of direct impact, which reduces the over-crushing phenomenon.

2. Finished product quality: The crushed granite particles are cubic in shape with low needle-like content, which meets the strict requirements of building aggregates on particle shape (such as the coarse aggregate standard for concrete).

♦♦ Stone Cone Crusher Has High Production Capacity and Low Energy Consumption

1. Large processing capacity: The continuous crushing capacity and deep cavity design of the cone crusher are suitable for large-scale stone crushing production lines, with an hourly processing capacity of tens to thousands of tons.

2. Energy consumption optimization: Compared with jaw crusher, impact crusher and other equipment, cone crusher has lower unit energy consumption, especially in hard rock crushing, its energy efficiency ratio is higher.

♦♦ Cone Crusher Spare Parts Have Long Life and Low Maintenance Cost

1. Wear resistance of key components: The moving cone and fixed cone lining are made of high manganese steel or composite alloy, and the discharge port can be adjusted through the hydraulic system to extend the service life.

2. Reduce downtime: The replacement cycle of wear parts is long (for example, the life of the liner in granite crushing can reach hundreds of hours), reducing the maintenance frequency and the risk of production interruption.

♦♦ Automation and Stability of Cone Crushering

1. Intelligent control system: Modern cone crushers are equipped with hydraulic adjustment, iron protection, automatic cavity cleaning and other functions, which can monitor the load and discharge in real time to avoid equipment damage.

2. Smooth operation: The eccentric sleeve and main shaft structure design reduce vibration, suitable for long-term continuous operation and reduce failure rate.

♦♦ Cone Crusher’s Adaptability to Multi-stage Crushing

Secondary/tertiary crushing is preferred: In the granite crushing process, the combination of “jaw crusher (coarse crushing) + cone crusher (medium and fine crushing)” is usually used. As a medium and fine crushing equipment, cone crusher can accurately control the discharge particle size (such as 10-50mm), providing ideal raw materials for subsequent sand making or direct use.

♦♦ Disadvantages of Other Equipment Compared to Cone Crusher

1. Impact Crusher: Although the particle shape is better, the hammer wears very quickly (the service life may be less than 100 hours under granite conditions), and the overall cost is high.

2. Jaw Crusher Machine: suitable for coarse crushing, but low efficiency and uneven product particle size in medium and fine crushing.

♦♦ Summary

Cone Crusher is an ideal choice for crushing hard rocks such as granite, due to its wear resistance, high efficiency, low maintenance and finished product quality. It is especially suitable for large-scale and continuous sand and gravel aggregate production lines.
