What a 35 tph mobile crushing plant for rare earth ore includes

A typical mobile crushing plant for rare earth ore is built on a heavy‑duty wheeled or track chassis and includes primary crushing and optional secondary stages. For 35 tph, the Type M‑RE35 is a widely used configuration:

• Primary jaw crusher (Type J-600x900) – 75‑90 kW motor, feed opening up to 450 mm, CSS 60‑100 mm. Reduces run‑of‑mine ore to 40‑80 mm.

• Optional secondary jaw or cone crusher – For finer reduction, a cone crusher or a second jaw can be added.

• Vibrating screen (1,500 x 4,500 mm, single deck) – Polyurethane panels for accurate sizing.

• Belt conveyors, control panel, and optional diesel generator (250 kVA) – For off‑grid operation.

Many rare earth operations have adopted a single‑stage jaw crusher followed by a screen, achieving 30‑40 tph of minus 40 mm product suitable for further grinding and beneficiation.

Key features that lower your cost per ton of rare earth ore

When you evaluate a mobile crushing plant 35 tph for rare earth ore in Mountain Pass USA, focus on features that directly reduce operating expenses:

• Reversible Mn18%+Cr jaw plates – Last 3,000‑5,000 hours in abrasive bastnäsite, 30‑50% longer than standard Mn14%.

• Vibrating grizzly feeder – Removes fines below the CSS before the crusher, extending jaw plate life and increasing net throughput.

• Magnetic separator (optional) – Removes tramp metal, protecting the crusher.

• Dust suppression system – Water sprays or a bag filter to comply with US EPA standards for particulate emissions.

• Electric drive with optional diesel backup – Grid power is available at Mountain Pass, but a generator ensures operation during outages.

How to optimize the mobile plant for rare earth crushing

Rare earth ore at Mountain Pass is typically processed by grinding and flotation. To maximize efficiency:

• Set jaw crusher CSS at 60‑80 mm – Produces a 0‑80 mm product. For finer feed to the mill, add a secondary cone crusher.

• Remove fines with the grizzly feeder – Scalping out material below 20‑30 mm reduces wear and increases net capacity.

• Monitor jaw plate wear every 200 hours – Rotate reversible plates when the bottom wears.

• Keep a spare set of jaw plates and screen panels on site – Shipping from overseas can take 2‑3 weeks.

• Use a dust suppression system – Rare earth dust can be a respiratory hazard; water sprays or a bag filter are essential.

Compliance with US regulations

The Mountain Pass mine operates under strict environmental and safety regulations (EPA, MSHA). OCP’s mobile crushing plant can be equipped with:

• Stage V diesel engine (or electric drive) – Meets EPA Tier 4 emissions standards.

• Dust collector – Bag filter for dry crushing to keep particulate emissions below limit.

• Sound‑attenuated enclosure – Reduces noise to comply with OSHA requirements.

• Emergency stop system – Located on all sides of the plant.

OCP provides full documentation for US import (EPA, DOT, customs). All equipment can be inspected before shipment.
