The gyratory crusher is a highly efficient machine specialized in large-scale ore and rock coarse crushing operations. Adopting high strength structure and innovative design, it can easily crush all kinds of hardness materials. With large handling capacity and high crushing ratio, the gyratory crusher can quickly produce high-quality raw materials with uniform particle size and improve production efficiency.
Product features
Efficient crushing
Can quickly crush ores and demonstrations of various hardness, the production efficiency is much higher than many traditional coarse crushing equipment, to provide sufficient raw materials for the subsequent processing process.
Stable and reliable
The use of high-strength materials, durable structure, can withstand large crushing particles and impact, in harsh environments can also be stable operation, low failure rate.
Intelligent adjustment
The discharge port adjustment system It can adjust the particle size of the discharged material according to the demand and the characteristics of the material to ensure uniform particle size and meet the diversified production requirements.
Environmental protection and energy saving
Optimize the design of crushing chamber and transmission system to reduce the operating energy consumption, adopt sealed dustproof device to reduce the emission of dust, which is in line with the environmental protection production standards.
When the gyratory crusher is working, the motor drives the eccentric sleeve to rotate through the pulley and transmission shaft, and the eccentric sleeve drives the centerline of the moving cone crusher to do the rotary oscillation movement. When the moving cone is close to the fixed cone, the materials in the crushing chamber will be crushed by the extrusion, bending and impact of the moving cone and the fixed cone; when the moving cone is far away from the fixed cone, the crushed materials will be discharged from the discharge port under the action of its own gravity, and the moving cone will keep on doing the rotary oscillation movement, so that the crushing and discharging process will continue to be carried out and the continuous crushing of the materials will be realized.

|
Large processing capacity |
The production capacity of 500-6000t/h is suitable for large-scale raw material processing in mines and large-scale infrastructure, avoiding production line bottlenecks caused by insufficient crushing efficiency. |
|
High fragmentation ratio |
It can crush large ore blocks of 1.5 meters at once to below 165mm, reducing the number of crushing stages and lowering equipment investment and energy consumption costs. |
|
Controllable particle shape |
The finished products are mostly cubic in shape with low needle like content, meeting the strict requirements of high-end building materials (such as high-strength concrete) for aggregate particle size. |
|
Adapt to hard materials |
The crushing efficiency of hard rocks such as granite (compressive strength>200MPa) is significantly higher than that of jaw crushers, and the equipment wear is lower. |
FAQ
Q: What materials are gyratory crushers suitable for processing?
A: Gyratory crushers are widely used in mining and large-scale sand and gravel aggregate sites, and can process ores and rocks of various hardnesses, such as limestone, iron ore, granite, etc.
Q: What is the general maintenance cycle of the equipment?
A: The maintenance cycle is affected by factors such as material properties and production load. It is generally recommended to carry out a comprehensive inspection and maintenance after 800 hours of operation, and vulnerable parts need to be replaced according to the wear condition.
Q: How to troubleshoot abnormal vibration during equipment operation?
A: (1) Check whether the feeding is uniform. If the feeding is uneven, it may cause the dynamic cone to be unbalanced in force. It is necessary to adjust the frequency of the feeder to ensure that the material continuously and stably enters the crushing chamber.
(2) Check the wear condition of the crushing liner. When the unilateral wear of the liner exceeds 20mm, it will destroy the balance of the dynamic cone, and the liner at the opposite position needs to be replaced immediately.
(3)Check the clearance between the eccentric sleeve and the main shaft. The normal clearance is 0.2-0.4mm. If it exceeds 0.6mm, it is necessary to adjust by increasing or decreasing shims to avoid vibration caused by excessive clearance.
Q: How to reduce equipment energy consumption through operation?
A: (1) Feeding control: Maintain the matching between the material particle size and the feed inlet. When more than 80% of the material particles in the feed are close to the maximum feed size, energy consumption will increase by 15%. It is recommended to control the reasonable particle size proportion through pre-screening with a vibrating screen.
(2) Speed adjustment: Adjust the main shaft speed for materials of different hardness. When processing hard materials such as quartzite, increasing the speed by 10% from the standard value can effectively improve the crushing efficiency, but it is necessary to simultaneously increase the lubrication flow by 15% to prevent overheating.
(3)Clearance optimization: Regularly measure the clearance between the impact plate and the hammer, and control it within the range of 15-25mm, which can reduce energy consumption by 8%-12%, while ensuring that the finished product shape meets the standard.
