Double-chamber hard rock crusher

Double-chamber Hard Rock Crusher

The dual-chamber hard rock crusher is a mining crushing equipment developed by Dingli, designed to solve the problems of high equipment wear and poor particle shape in the process of crushing hard rock. Based on the company's years of research and development in hammer crushers, and combined with the actual conditions of the crushing production line, this equipment is particularly suitable for crushing hard materials such as granite, pebbles, and river pebbles.

Applicable Materials:

Granite, river pebbles, and other high-hardness materials

Processing Capacity:

150–350 T/H

Feed Size:

≤ 180 mm

Machine Details

Detailed introduction to the double-chamber hard rock crusher structure and design

Double-chamber Hard Rock Crusher

Rotor Assembly

The entire rotor is equipped with a wear-resistant sheath to protect the rotor body from wear and ensure stable equipment operation.

Counterattack Liner Assembly

Made of high-chromium molybdenum alloy wear-resistant material, the reinforced version is more durable.

Hydraulic Opening Assembly

Fully exposes the interior of the equipment cavity, facilitating maintenance and replacement of parts.

Core Advantages

Core advantages of the double-chamber hard rock crusher design

Dual Chamber

Higher capacity with efficient impact crushing.

Symmetrical Structure – Dual symmetrical chambers allow more materials to be processed at one time, increasing overall output.
Powerful Impact – High-speed rotating hammers deliver strong impact force to materials fed from the top.
Secondary Crushing – Materials strike the impact plates after gaining kinetic energy, ensuring effective secondary crushing.
Self-Crushing Action – Materials collide with each other inside the chamber, enhancing crushing efficiency.
Uniform Output – After repeated impact and grinding, materials reach the required size and discharge smoothly from the lower side outlet.

Stable Performance

Reliable structure with easy maintenance.

Secure Liner Fixing – Raised positioning blocks on the back of the main liner firmly secure its position, while bolts only provide tightening force.
Optimized Structure – Eliminates the traditional shaft retaining plate and uses side plate sleeves to secure the hammer shaft for a simpler, more practical design.
Stable Operation – Improved structural design ensures consistent and stable working performance.
Easy Inspection – An inspection door on one side of the upper casing allows convenient monitoring and maintenance.

Easy Operation

Convenient control with reduced manual effort.

Independent Structure – The casing and rotor are independently designed, allowing lateral movement of the casing relative to the rotor.
Reversible Rotor – The rotor can rotate forward and reverse, replacing manual hammer flipping and reducing labor intensity.
Lower Maintenance Cost – Minimizes manual workload and reduces maintenance expenses.
Remote Adjustment – Enables remote control to adjust the gap between the hammer and main liner without stopping the machine.

Easy Maintenance

Simplified design reduces labor and service costs.

Independent Structure – The casing and rotor are separately designed for more flexible operation.
Lateral Adjustment – The casing can move left and right relative to the rotor, making maintenance more convenient.
Reversible Rotor – Forward and reverse rotor rotation replaces manual hammer flipping.
Reduced Labor Cost – Eliminates traditional manual adjustment of the movable liner, lowering labor intensity and maintenance expenses.

Application Scenarios

Zhongyu Dingli undertakes the construction of sand and gravel aggregate production lines with an hourly output of 100-6000 tons, and provides intelligent control systems for mines.

Hunan 250–350 TPH Aggregate & Sand Production Line

The raw material is evenly fed by a vibrating feeder into a hammer crusher for primary crushing. The crushed material is then conveyed to a KPC1313 double-cavity hard rock crusher for secondary crushing and shaping.

Taiyangshan Cement Aggregate Production Line Installation Site

The image above shows the installation site of the Taiyangshan Cement project in Ningxia. The remaining equipment will be transported to the production site in succession to complete the overall construction of the production line. The project is equipped with a comprehensive environmental protection and dust removal system, ensuring a clean production environment and significantly reducing dust emissions.

250–300 TPH Granite Aggregate Production Line in Xichang, Sichuan

The image above shows the production site of the 300 TPH granite aggregate production line. Unlike traditional hard rock crushing lines that require multiple crushers, this solution uses only one hard rock crusher developed by our company, significantly reducing equipment investment costs. Additionally, the crusher has a large material intake capacity per unit time, enabling rapid and efficient crushing operations.

Ningxia 6 Million Tons per Year Aggregate Production Line

The aggregate production line and the integrated intelligent mining management system were fully supplied and installed by Zhongyu Dingli.
