What is the recommended maintenance schedule for the hydraulic system on this tracked cone crusher?

The hydraulic system requires regular inspection to maintain reliability. Check the hydraulic oil level daily and top up with ISO VG 46 anti-wear hydraulic oil as needed. Replace the oil filter every 500 operating hours and change the oil every 2,000 hours or annually, whichever comes first. Inspect hoses and fittings for leaks or abrasion every 250 hours. The accumulator should be pre-charged to 120 bar nitrogen every 1,000 hours. Keep the oil cooler clean by blowing compressed air through the fins weekly. Record hydraulic pressure during operation; a drop below 280 bar may indicate internal leakage or pump wear. Following this schedule ensures the tramp release system functions correctly and extends component life.

How does the pre-screen increase throughput and reduce wear on the cone crusher?

The integrated pre-screen, measuring 1200 mm × 2400 mm, removes material smaller than the CSS before it enters the crushing chamber. This bypasses fines that would otherwise consume crushing energy and contribute to liner wear without size reduction. By removing up to 20% of the feed as finished product, the crusher's throughput capacity is effectively increased by 15–20% for the same power draw. Additionally, the reduced volume of material in the chamber lowers the load on the mantle and concave, extending liner life by up to 25%. The pre-screen can be equipped with a belt magnet to remove rebar from demolition waste, further protecting the crusher.

Can this mobile crusher be used in a multi-stage crushing circuit with a primary jaw crusher?

Yes, the tracked mobile multi-cylinder hydraulic cone crusher is designed for secondary and tertiary duty and can be paired with a mobile jaw crusher as the primary unit. The 500 mm feed opening accepts the output from a primary jaw crusher with a 1000 mm feed opening, typically producing a 0–300 mm product. The cone crusher then reduces this to 0–40 mm or finer, depending on the CSS setting. For a complete circuit, a mobile screen can be added to close the loop, with oversize returned to the cone crusher. The PLC system can be integrated with the primary unit's control for automated start/stop sequencing, ensuring smooth operation and preventing blockages.

How Does the Tracked Mobile Multi-Cylinder Hydraulic Cone Crusher Optimize On-Site Crushing?

The tracked mobile multi-cylinder hydraulic cone crusher integrates a 1300 mm cone crusher with a 365 kW diesel engine and a heavy-duty tracked undercarriage, creating a self-contained crushing plant that moves with the job. Unlike stationary installations, this unit can be repositioned within the quarry or between sites without dismantling, reducing setup time and civil works. The multi-cylinder hydraulic system provides active overload protection: when uncrushable material enters the chamber, hydraulic cylinders release pressure and allow the tramp to pass, then automatically reset the gap. The CSS can be adjusted hydraulically from the control panel, enabling quick changes between 10 mm and 40 mm to meet different aggregate specifications. With a maximum feed size of 500 mm and a throughput of 300 t/h, it handles abrasive rock such as granite and basalt efficiently.

Typical applications include secondary and tertiary crushing in aggregate production, where consistent cubical shape and high reduction ratios are required. In mining, it serves as a mobile secondary crusher for ore pre-concentration or heap leach feed preparation. Construction and demolition waste recycling benefits from the mobility and the ability to separate rebar with an optional magnet. The integrated pre-screen removes fines before crushing, increasing the available power for size reduction and reducing wear on the cone liners. The 48-ton operating weight and 16.5-meter transport length allow road transport with standard permits, making it suitable for contractors who move between multiple pits or projects. The PLC system logs operating parameters and alerts operators to abnormal conditions, such as high oil temperature or low hydraulic pressure, preventing unplanned downtime.

Compared to other models in the range, this 300 t/h unit fills the gap between compact 200 t/h track-mounted crushers and larger 400 t/h units that require more transport logistics. Its 500 mm feed opening is 25% larger than the 400 mm opening of the smaller model, reducing the need for primary screening and allowing direct feed from a primary jaw or impact crusher. The 1300 mm cone head diameter provides a longer crushing stroke and higher reduction ratio than the 1000 mm head used in lighter units, resulting in better product shape and less recirculating load. For operations that need to produce high-quality aggregates with a mobile setup, this model offers a balance of capacity, mobility, and hydraulic control that is hard to match.

Hydraulic tramp release and automatic reset protect the crusher from uncrushable material, reducing downtime by up to 30% compared to spring cone crushers.
Integrated pre-screen with 1200 mm × 2400 mm dimensions removes fines before crushing, increasing net throughput by 15–20%.
PLC control with touchscreen interface provides real-time monitoring of CSS, power draw, and hydraulic pressure, enabling precise adjustment and predictive maintenance.

Core Technical Features and Quantified Advantages

STEP 1

Multi-Cylinder Hydraulic System with 320 Bar Relief Pressure

The cone crusher is equipped with four hydraulic cylinders that provide a clamping force of up to 320 bar, ensuring stable operation under high crushing forces. This system allows hydraulic adjustment of the CSS from 10 mm to 40 mm with a resolution of 1 mm, and enables automatic tramp release when uncrushable material enters the chamber. The hydraulic oil is cooled by a dedicated radiator to maintain viscosity, extending component life in ambient temperatures up to 45°C.

STEP 2

1300 mm Cone Head Diameter and 500 mm Feed Opening

The 1300 mm cone head diameter, combined with a 500 mm feed opening, provides a reduction ratio of up to 6:1 in a single pass. The crushing chamber is available in coarse, medium, and fine configurations to suit different feed gradations and product requirements. The large feed opening reduces the need for secondary screening and allows direct feed from a primary crusher, simplifying the flowsheet and reducing equipment count.

STEP 3

Tracked Chassis with 48,000 kg Operating Weight and 16.5 m Transport Length

The tracked undercarriage features 600 mm wide steel tracks with hydraulic drive, allowing travel speeds up to 1.2 km/h on uneven terrain. The 48,000 kg operating weight provides stability during crushing, while the 16.5 m transport length and 3.2 m width enable road transport with standard low-bed trailers. The tracks are driven by independent hydraulic motors with planetary gearboxes, delivering high torque for climbing grades up to 20°.

STEP 4

365 kW Diesel Engine with PLC Control and Remote Monitoring

A 365 kW (490 hp) diesel engine powers the hydraulic system and the crusher, with an optional generator for auxiliary equipment. The PLC control system features a 7-inch touchscreen and provides real-time data on engine load, hydraulic pressure, CSS, and bearing temperatures. Remote monitoring via GSM modem allows service personnel to diagnose issues and update parameters without site visits, reducing response time and improving uptime.
