Fixed-spindle, compact, and high-efficiency laminated crushing needle plate
Cone Crusher Equipment Overview
The multi-cylinder cone crusher is a workhorse in the medium and fine crushing sector, widely used in metal and non-metal mining, cement, sand and gravel aggregate, metallurgy, and other industries. With a capacity of 100–1,200 t/h and a maximum feed size of ≤230 mm, it effectively crushes various ores and rocks with a Mohs hardness of 16 or below. The fixed main shaft structure, resembling a steel-reinforced pillar, offers high load-bearing capacity, a compact design, and a small footprint, enabling high productivity even in confined spaces. The multi-layer inter-material laminar crushing chamber functions like a precision engine; mutual compression of materials significantly enhances crushing efficiency and the proportion of fine particles, while markedly reducing the content of acicular and flaky particles and wear on wear-resistant components. Features such as tin-bronze sleeve rolling bearings, German AKG air cooling, a large-capacity accumulator pressure-maintaining cylinder, adhesive-free liner plates, and an integrated hydraulic sealing system work in concert to ensure the equipment’s high efficiency, durability, and low maintenance requirements.
Cone Crusher Equipment Highlights
1. Compact, High-Output Fixed Spindle: The fixed spindle structure offers high load-bearing capacity and a compact design with a small footprint, enabling high production capacity even in limited spaces.
2. Laminated Crushing Reduces Needle- and Flake-Shaped Particles: The multi-layer laminated crushing principle uses mutual material compression to improve efficiency and increase the proportion of fine particles, simultaneously reducing the content of needle- and flake-shaped particles and wear part consumption.
3. High-Load Bronze Bushings: Tin-bronze rolling bearings maintain exceptional load-bearing capacity even under harsh conditions with high dust levels and severe impacts, thereby reducing production costs.
4. Intelligent Temperature Control Protection: Temperature sensors installed in the return oil lines precisely monitor oil temperature to ensure stable operation.
5. Low-Noise Helical Bevel Gears: The transmission system uses helical bevel gears, ensuring reliable, smooth, and quiet operation while extending equipment lifespan.
6. Adhesive-Free Liner Quick-Change: Thickened one-piece liners with an improved mounting method eliminate the need for adhesives, enabling quick and convenient replacement and significantly reducing maintenance costs.
7. Integrated Hydraulic Seals: Thin-film oil lubrication extends service life; high-performance rubber seals resist wear and prevent leaks; spherical dynamic seals ensure full contact to keep the lubricating oil clean.
8. German AKG Air Cooling: Equipped with a German AKG air cooler, it offers excellent heat dissipation and eliminates oil-water mixing failures caused by cold water.
9. Large-Capacity Accumulator for Pressure Maintenance: Large-diameter, high-capacity accumulators provide excellent buffering performance and rapid response, ensuring safer equipment operation.
10. Simple Installation Base: Compatible with manual installation bases, installation is simple and labor-saving, with significantly reduced foundation requirements, resulting in lower investment and faster commissioning.
Cone Crusher Application Scenarios
Metal Mining: Medium and fine crushing of iron ore, copper ore, etc. Non-metallic Mining: Medium and fine crushing of limestone, granite, etc. Cement Industry: Medium and fine crushing of raw materials. Sand and Gravel Aggregates: Medium and fine crushing for high-quality aggregates. Metallurgical Industry: Medium and fine crushing of ore
Cone Crusher Process Flow
Raw Material Bin → Vibrating Feeder → Jaw Crusher (Primary Crushing) → Multi-cylinder Cone Crusher (Secondary Crushing) → Multi-cylinder Cone Crusher/Fine Crushing Type (Fine Crushing) → Circular Vibrating Screen (Classification and Screening) → Finished Product Bin
The secondary crushing stage features a medium-sized chamber and a compact, space-saving fixed-shaft design. The inter-particle compression principle of the laminar crushing mechanism enhances efficiency and significantly reduces the content of needle- and flake-shaped particles. The fine crushing stage switches to a fine chamber configuration, ensuring uniform and controllable final particle size. Tin-bronze sleeve bearings and German AKG air cooling ensure long-term reliable operation under harsh conditions, while wear-resistant liners eliminate the need for replacement, allowing for quick maintenance without production downtime. The large-capacity accumulator pressure-retaining cylinder responds quickly to overloads and provides excellent cushioning, ensuring equipment safety. Closed-circuit screening returns oversized material for re-crushing, resulting in a well-graded final product.

Cone Crusher FAQ
What are the advantages of the inter-material laminar crushing process in multi-cylinder cone crushers?
The DLHPT multi-cylinder cone crusher employs a multi-layer inter-material laminar crushing principle, where materials are crushed by mutual compression within the chamber. Reliable Multi Cylinder Cone Crusher This process offers high efficiency, a high proportion of fine particles, and a significant reduction in the content of needle- and flake-shaped particles. It serves as the core medium-to-fine crushing equipment in multi-cylinder cone crusher production lines for producing high-quality aggregates.
Is it easy to replace the adhesive-free liners?
It is very convenient. The improved mounting method for the thickened, one-piece liners eliminates the need for adhesive. High Performance Crushing Equipment A single replacement takes only 4 hours, reducing replacement time by approximately 50% compared to traditional adhesive liners, and significantly lowering maintenance downtime for the entire multi-cylinder cone crusher production line.
