Composite Cone Crusher

Laminated Crushing Chamber for Superior Particle Shape

The optimized laminated crushing chamber geometry — featuring a steeper nip angle, longer parallel zone, and carefully profiled mantle-to-concave clearance curve — ensures that material is crushed multiple times between the mantle and concave surfaces as it descends through the chamber, rather than falling freely through a wide open chamber after a single compression event. This repeated inter-particle compression produces a well-shaped, cubical product with significantly lower elongated and flaky particle content compared to conventional cone and spring cone crushers, meeting the most stringent particle shape specifications for concrete aggregate, asphalt surface course, and railway ballast applications.

Hydraulic CSS Adjustment, Millimeter-Level Precision

The hydraulic main shaft lifting system allows the closed-side setting to be adjusted upward or downward with millimeter-level precision from the operator control panel during crusher operation, without stopping the machine or using mechanical tools. This real-time CSS adjustment capability allows operators to compensate for liner wear continuously throughout the liner service life, maintaining consistent output product gradation from the first hour of operation to the last — eliminating the gradual product size drift that affects mechanically adjusted spring cone crushers as liners wear.

Fast Hydraulic Overload Protection & Automatic Reset

When uncrushable tramp metal or an oversize lump causes the crushing force to exceed the set hydraulic pressure limit, the hydraulic overload protection system instantaneously releases the pressure by allowing oil to flow into the accumulator, dropping the main shaft and opening the CSS to pass the obstruction — a response time of less than 0.5 seconds compared to 1–3 seconds for mechanical spring systems. Once the obstruction clears, the hydraulic system automatically returns the main shaft to the original CSS setting without any manual intervention, minimizing production downtime from overload events.

High Crushing Ratio, Reduced Downstream Processing Load

The combination of optimized chamber geometry, high eccentric throw, and laminated inter-particle crushing delivers a crushing ratio of 5:1 to 8:1 per pass — significantly higher than the 4:1 to 6:1 typical of conventional spring cone crushers. This higher single-pass reduction ratio reduces the recirculating load in closed-circuit crushing operations, increases circuit throughput, and reduces the feed size requirement for downstream ball milling — lowering overall comminution energy consumption per tonne of final product.

Intelligent Control System with Real-Time Monitoring

The standard PLC-based control system monitors CSS position, crushing force, main shaft displacement, oil temperature, oil pressure, oil flow, feed rate, and motor current in real time, with automatic alarms and shutdown sequences triggered by any out-of-limit condition. Optional integration with plant DCS or SCADA systems via Modbus or Profibus enables remote monitoring, automated CSS adjustment based on product size feedback, and predictive maintenance scheduling based on liner wear rate trends — reducing on-site operator requirements and improving overall crushing circuit availability.

Universal Liner System, Low Spare Parts Inventory

The mantle and concave liner profiles are interchangeable across coarse, medium, fine, and extra-fine chamber configurations on the same crusher frame, allowing a single machine to switch between secondary and tertiary crushing duties by changing only the liner set. This universal liner system minimizes the spare parts inventory required to support multiple crushing stages, reduces procurement complexity, and ensures liner availability even in remote locations by standardizing on a single replaceable wear part specification across the entire crushing circuit.
