BRAUN CHIPMUNK VD67 JAW CRUSHER

Braun Chipmunk VD67 Jaw Crusher in Sand and Aggregate Production

The Braun Chipmunk VD67 Jaw Crusher is a robust, high-performance primary crusher designed for hard rock reduction in sand and aggregate production lines. Its compact size (12″ x 6″ jaw opening) and heavy-duty construction make it ideal for processing quarried stone, recycled concrete, and mineral ores.

Key Features & Technical Specifications

– Feed Opening: 12″ x 6″ (305mm x 152mm)
– Capacity: 1-3 TPH (varies by material hardness)
– Motor Power: 3-5 HP (2.2-3.7 kW)
– Max Feed Size: 4″ (102mm)
– Weight: 1,100 lbs (500 kg)

The crusher utilizes a unique “forced feed” design with reversible jaws for extended wear life. Its alloy steel construction ensures durability in abrasive environments.

Typical Production Line Integration

In a sand/aggregate plant, the VD67 often serves as:
1. Primary crushing unit for small-scale operations
2. Secondary crusher after grizzly screening
3. Laboratory testing equipment for ore samples

Common downstream equipment includes:
– Vibrating screens (e.g., 4’x8′ single deck)
– Cone crushers for finer reduction
– Sand washing systems

FAQ

Q: What’s the typical output size?
A: Adjustable from 0.25″ to 1.5″ (6-38mm).

Q: Can it handle wet/sticky materials?
A: Limited performance; pre-screening recommended.

Q: Maintenance interval?
A: Lubricate bearings every 40 operating hours; jaw inspection every 200 hours.
