Disassembling a CMB RB150 cone crusher requires careful planning, proper tools, and adherence to safety protocols. Below is a structured guide to help you through the process.
—
1. Safety Precautions
– Lockout/Tagout (LOTO): Ensure the crusher is electrically isolated and hydraulic systems are depressurized.
– Personal Protective Equipment (PPE): Wear gloves, safety glasses, and steel-toe boots.
– Lifting Equipment: Use cranes or hoists rated for heavy components (mantle, bowl liner, etc.).
– Workspace: Clear the area of obstructions and ensure stable footing.
—
2. Tools & Equipment Needed
– Hydraulic torque wrench
– Impact gun
– Bearing pullers
– Hoist/crane (rated for heavy loads)
– Soft-faced hammers
– Seal removal tools
– Lubricants (penetrating oil for seized bolts)

3. Disassembly Steps
# A. Pre-Disassembly Preparation
1. Drain Fluids: Remove hydraulic oil and lubricants from the crusher.
2. Document Components: Take photos or label parts for reassembly reference.
3. Remove Feed Hopper & Guards: Detach any external covers or feed components.
# B. Mantle & Concave Removal
1. Backing Nut Removal:
– Use a hydraulic wrench to loosen the mantle retaining nut.
– Rotate the eccentric counterclockwise to relieve pressure.
2. Mantle Extraction:
– Lift the mantle carefully using a crane.
– Inspect for wear or damage.
3. Bowl Liner (Concave) Removal:
– Remove bowl adjustment ring bolts.
– Lift the bowl assembly using a crane.
# C. Eccentric & Head Assembly
1. Disconnect Drive Components:
– Remove belts or couplings connecting to the motor.
2. Extract Eccentric Bushings:
– Use a bearing puller to remove eccentric bushings.
3. Remove Main Shaft:

– Check bearings for wear.
# D. Hydraulic & Adjustment System
1. Release Hydraulic Pressure:
– Bleed hydraulic cylinders (if equipped).
2. Remove Tramp Release Cylinders:
– Disconnect hoses and unbolt cylinders.
