Well-proven and with flexibility of configuration, the Essa® Model JC3000 Jaw Crusher is a heavy duty, primary jaw crusher used in sample preparation and plant applications.

• Large core and lump crushing: 300 mm x 200 mm jaw opening accepts large input feed size up to 170 mm. 
• Reduced capital cost: flexibility of use allows for continuous or batch use in laboratory, field and plant applications. 
• Flexibility of installation: available in upright stand-alone or low-profile configuration. 
• High throughput: rapid and powerful crushing at 3,000 kg per hour throughput. 
• Increased productivity: efficient reduction ratio, with 25 mm product size. 
• Increased availability: designed with a mechanically simple but reliable single toggle for ease of maintenance and repairs. 
• Improved quality: reversible and interchangeable jaw plates extend wear part life.

Excellent capabilities 
The hardy Essa JC3000 Jaw Crusher handles high workloads and has been tried and tested in both laboratories and plants, making it a reliable machine with recognisable brand-name quality. It comes in two configurations: either for stand-alone analytical or metallurgical laboratory use, or for continuous use such as in mechanical sampling stations or pilot plants. The footprint dimensions of the upright model are 645 mm x 920 mm. The crusher has a 300 mm x 200 mm jaw inlet and can handle samples up to 170 mm.

High productivity 
A well-proven single toggle jaw crusher, the Essa JC3000 is a heavy-duty, low-maintenance machine. It readily accepts soft to very hard ore, drill core, rock and similar particulate up to 170 mm, i.e. 85% of its jaw opening. Throughput is generally 3,000 kg per hour and the machine has a good reduction ratio – with 25 mm product size it provides faster and more efficient crushing with reduced process stages. Maintenance downtime is minimised thanks to the simple jaw gap adjustment which provides good control of product sizing, while the use of roller bearings throughout makes the machine reliable at high load capacity.

Flexibility of configuration and heavy-duty construction 
The upright, standalone Essa Jaw Crusher Model JC3000 has a feed hopper and sample drawer with dust extraction points, while the low-profile configuration has a fabricated steel base for mounting on a customer’s support frame or concrete footing. Standard features throughout include rugged, fabricated steel construction, electric pre-wiring with an IP65-enclosed stop/ start and motor protection station, and vertically serrated chrome steel jaw plates which are reversible and interchangeable for extended life.

Safety features 
Safety features of the JC3000 include the full drive guarding which complies with occupational health and safety standards, while the two dust extraction points to remove airborne dust at the inlet and sample
