350-450 t/h Mobile Stone Crusher | Hard Rock Cone Crusher Production Line
In mining and infrastructure aggregate production, capacity is the core benchmark for measuring equipment value. A processing capacity of 350-450 tons/hour falls precisely in the golden range between medium-scale operation and large-scale project supply. For contractors seeking capacity upgrades, this tonnage class of equipment can meet the continuous supply needs of large-scale mixing plants while offering relocation flexibility, avoiding the problems of long installation cycles and high energy consumption associated with ultra-large production lines.
With the arrival of the Year of the Horse (2026), the mining equipment industry is accelerating its transformation towards mobility and intelligence. As a manufacturer specializing in mobile crushing equipment for mines, we understand that integrating efficient crushing, precise screening, and smooth conveying within limited space is key to achieving a stable capacity of 350-450 tons/hour.
In-depth Analysis: The Core Technology of a 350-450 Tons/Hour Production Line
1. Main Unit Selection
To achieve a stable crushing capacity of 350-450 tons/hour, the main unit must possess high rotational speed and large crushing force. Our mobile jaw crusher features a 15% increased main chamber depth, coupled with a hydraulic adjustment system, maintaining a throughput of 400 tons/hour even when processing raw materials with a particle size of up to 800mm. For fine crushing, the cone crusher's layered crushing technology ensures that the finished product contains less than 12% needle-like and flaky particles.
2. Screening System:
High-production lines require high-load screening. Utilizing a four-layer vibrating screen with an inclined angle design, the screening area reaches 18㎡, effectively preventing screen clogging under high-production conditions. Combined with a frequency converter-controlled feeder, it ensures uniform distribution of stone across the entire screen surface, increasing the screening throughput to over 93%.
3. Mobile Chassis:
Fixed production lines require 30-45 days from installation to commissioning, while our tire/tracked mobile crusher can start production within 8 hours of arrival. The fully hydraulically driven tracked chassis has a small turning radius, eliminating the need for trailers during relocation within the mining area, significantly reducing non-productive time costs.
Four Core Advantages of Mobile Crushing and Screening Stations:
1. Stable Production Capacity and Strong Peak Overload Capacity
The heavy-duty rotor bearings and main frame, designed specifically for 350-450 tons/hour operation, can withstand the impact of large stones. Actual test data shows that with a mud content not exceeding 5%, the equipment can achieve a daily output of over 8,000 tons of finished material.
2. Controllable Particle Shape and Reasonable Grading
By adjusting the speed of the impact crusher hammers or the discharge port of the cone crusher, four mainstream aggregate sizes—0-5mm, 5-10mm, 10-20mm, and 20-31.5mm—can be quickly produced. Grading adjustment time has been reduced from the traditional 45 minutes to 8 minutes.
3. Dual Power Supply, Suitable for Remote Mining Areas
For mines in Africa, Southeast Asia, and Central Asia with unstable power grids, the equipment comes standard with a diesel engine direct drive option. Automatic switching between the main motor and auxiliary power ensures uninterrupted operation of the crushing line 365 days a year. 4. Intelligent Operation and Maintenance, Reducing Manual Intervention
The remote PLC control system monitors 36 parameters in real time, including bearing temperature, lubricating oil pressure, and belt misalignment. Early warning information is directly pushed to the project manager's mobile phone, enabling predictive maintenance and reducing spare parts loss rate by 18%.

Related Recommendation: Building Your Mobile Crushing and Screening Fleet
A single unit cannot independently complete the entire process of "stone crushing-screening-recycling".
For a scale of 350-450 tons/hour, we recommend the following standard unit combination:
• Mobile Jaw Crusher: Responsible for primary coarse crushing, output 0-200mm.
• Mobile Cone/Impact Crusher: Responsible for secondary medium crushing, particle shape shaping.
• Mobile Screening Station: Responsible for grading and screening, finished product stockpiling.
• Mobile Material Conveyor: Connects all units, achieving seamless continuous operation.
This combination requires no concrete foundation, and the unit can be commissioned in just 2 days, making it particularly suitable for EPC turnkey projects with tight schedules.
Frequently Asked Questions (FAQ)
Q1: Can your mobile crusher crush muddy sandstone with high moisture content?
A: Yes. For high-moisture materials, we recommend installing a bar feeder at the feed inlet and adding a mud scraper to the main conveyor head. For 350-450 tons/hour production lines, we standardly equip them with a twin-shaft vibrating feeder, which can effectively remove more than 90% of the mud, preventing clogging of the crushing chamber.
Q2: Will the power decrease when the equipment operates in high-altitude areas (above 4000 meters)?
A: For high-altitude projects, we provide a high-altitude booster power pack. By recalibrating the engine ECU and increasing the air compressor's air tank capacity, we ensure that power loss is controlled within 5% at altitudes of 4500 meters, with a 100% start-up success rate.
Q3: Does this equipment require special tools to replace wear parts?
A: No need. We adhere to the "tool-free maintenance" design philosophy. The jaw plates are rotated with the assistance of hydraulic jacks, and the screen tensioning uses a quick-release plate mechanism. A mechanic can complete the replacement of the entire jaw plate set within 4 hours using the vehicle-mounted tools.
