PORTABLE JAW CRUSHERS

Reliable and highly productive

PORTABLE JAW CRUSHERS

Portable jaw crushers are wheel-mounted rock crushing machines engineered for primary crushing applications. Suitable for crushing hard and soft rock, such as granite, basalt, limestone, and as well recycled materials, portable jaw crushers are the optimal choice if you want to move the crushing plant from one site to another periodically. They are easily transportable between production sites and often utilized in aggregates production and recycling applications.

MEKA Portable Jaw crushers combine the rugged reliability of our jaw crushers with the high stroke grizzly feeders for a high production portable primary crushing machine. Frequency inverter for feeder speed control to optimize the feed are also key components of this range to make your crushing process easier.

We offer a wide range of portable jaw crushers to fulfil your primary crushing needs in the aggregates and mining sectors, designed with many features aimed at high capacity production and ease of operation. All units are built for durability and constructed from a robust heavy duty chassis frame which is fully assembled on a single trailer and mounted on double or triple axle bogies. The simple, yet effective design includes many benefits for quick set-up and ease of maintenance, resulting in more uptime and higher productivity.

FEATURES


High Performance and Reliability
MEKA MJ Jaw Crushers;

• Large feed opening with high capacity reduction
• Reliable and highly productive due to chamber geometry and feed arrangement,
• Ideal nip angle for smooth material flow, high reduction efficiency and single-toggle operation with a deep crushing chamber
• Easy setting adjustment for simple and efficient operation


MEKA MGF Grizzly feeders;

• With by-pass chute to divert grizzly fines to discharge or optional reject cross conveyor for removing of fines, thereby maximizing throughput and reducing wear
• Frequency inverter for feeder speed control in order to provide step less regulation of the feed rate


Safe and easy to operate and maintain

• Operator-friendly unit with flywheel covers, spacious and accessible platforms make the daily operation and maintenance simpler, safer, and faster.
• Removable electrical control panel can be located on the ground during operation
• Crusher mounted safety guards and multiple emergency stop buttons for safe
• Low emissions due to electrical operation, minimizing environmental impact

ADVANTAGES


• Compact layout and excellent stability
• Heavy duty chassis beams, strength analysis on structural parts and quality components for durability.
• All onboard components are electrically driven giving reliability and minimal maintenance.
• Low cost per tonne due to electric operation
• Quick to set-up and easy access for service and maintenance, resulting in more uptime and higher productivity
• Capable of operating in the most hostile environments.
