12 x 36 Kemco Jaw Crusher: Overview and Technical Specifications
The 12 x 36 Kemco Jaw Crusher is a robust primary crushing machine designed for heavy-duty applications in mining, aggregate production, and demolition recycling. Known for its durability and efficient performance, this jaw crusher has been utilized in various industrial operations since its introduction.
Design and Construction
The Kemco 12 x 36 jaw crusher features a 12″ x 36″ feed opening, allowing it to process medium to large-sized rock and ore efficiently. Its sturdy cast steel frame ensures long-term reliability under demanding conditions. The crusher employs a double-toggle (Blake-type) mechanism, which provides superior crushing force compared to single-toggle designs, making it suitable for hard and abrasive materials. .jpg)
Key Specifications
- Feed Opening: 12″ x 36″ (305 mm x 914 mm)
- Max Feed Size: Approximately 24″ (610 mm), depending on material hardness
- Crushing Capacity: Varies with settings but typically ranges between 50–150 tons per hour (TPH)
- Motor Power: Typically driven by a 75–100 HP electric motor or equivalent diesel/hydraulic power source
- Weight: Estimated at around 15,000–20,000 lbs (6,800–9,000 kg) depending on configuration
Applications
The Kemco 12 x 36 jaw crusher is commonly used in:
- Primary crushing of granite, basalt, and other hard rock formations
- Aggregate production for road base and concrete mixes
- Recycling operations involving reinforced concrete demolition debris
Maintenance and Wear Parts
Like all jaw crushers, the Kemco model requires periodic maintenance to ensure optimal performance. Key wear components include:
- Replaceable manganese jaw dies (fixed and movable)
- Toggle plates and seats
- Bearings and lubrication systems
Proper adjustment of the discharge setting helps maintain consistent product size while minimizing wear. .jpg)
Legacy and Availability
Kemco crushers were widely distributed in North America during the mid-to-late 20th century. While newer models from competitors like Metso (Nordberg), Sandvik, and Terex have since dominated the market, used Kemco jaw crushers remain operational in some quarries or are available through industrial equipment resellers.
For those considering purchasing a used unit, inspecting critical components—such as jaw dies, bearings, and structural integrity—is essential to avoid costly repairs post-acquisition.
In summary, the 12 x 36 Kemco Jaw Crusher remains a dependable choice for operators seeking a rugged primary crusher capable of handling tough materials with minimal downtime.
