A small portable primary jaw crusher powered by an aluminum (Al) frame or components would be an interesting concept, though most jaw crushers are built with steel for durability. However, if you’re looking for a compact, lightweight, and portable primary jaw crusher, here are key features and considerations:

Features of a Small Portable Primary Jaw Crusher:
1. Compact Design
– Lightweight (possibly with aluminum components) for easy transport.
– Mounted on a trailer or skid for mobility.
2. Primary Crushing Capability
– Handles hard rock, concrete, demolition debris, and aggregates.
– Feed size: Up to 12–14 inches (depending on model).
– Output size: Adjustable (typically 3–6 inches).
3. Power Options
– Diesel engine (for remote sites).
– Electric motor (if grid power is available).
4. Jaw Crusher Specifications
– Fixed or swinging jaw design.
– High manganese steel jaws for wear resistance (aluminum would not be suitable for crushing surfaces).
5. Portability
– Wheel-mounted or tracked for easy r
cation.
– Can be towed by a pickup truck or small tractor.
Example Models (Real-World Options):
While fully aluminum-bodied jaw crushers are rare due to strength requirements, some small portable options include:
– Metso Lokotrack LT96 (track-mounted, but steel construction).
– Komplet Lem Track 48-25 (compact mobile jaw crusher).
– Red Rhino 4000 Series (small portable crusher with steel frame).
Why Aluminum?
If you’re considering aluminum components:
– ✅ Lightweight for easier transport.
– ❌ Not ideal for high-stress crushing zones—steel is preferred for jaws and structural parts.
Best Alternative:
A hybrid design with an aluminum outer frame but steel jaws and internal components could balance weight and durability.
