NSS OM Jaw System

Keestracks patented NSS  (Non-stop overload safety system) is a hydraulic and electronic safety protection system that will progressively open the swing jaw to its max (but not excess max) opening to prevent overload or damage and pass through any uncrushable objects that could damage the jaw system. The NSS system will also regulate feeding to prevent overload while it clears the object and resets to its original settings.

Fuel Efficient

The B4 uses Keestrack's proven load sensing hydraulic pumps to save fuel. The system automatically detects where hydraulic power is needed and adjusts to suit. Only energy that is needed is produced saving fuel by reducing load when it's not needed..

Mobile and Adjustable

The B4 can be tracked around the site while continuing to crush material without any loss in power to any component, due to the load sensing pumps only delivering power where required. Additionally crushing settings can also be maintained and adjusted while tracking.

E-Machine Capable

The B4 is efficient and powerful and can be made more efficient with an e model available. The B4e takes the all the B4 features and design and turns it into a Diesel-Electric Hybrid even more efficient than a Diesel only engine and adds the ability to be run from a generator or plugged directly into the grid.

Key benefits
Keestrack B4 Jaw Crusher with Double Deck Pre-Screen
Double Deck Pre-Screen

With the addition of a double deck pre-screen the B4 can be set up to remove fines before getting to the primary crushing compartment, increasing performance and reducing unnecessary wear. It also allow for splitting out an additional specified product prior to crushing.

Keestrack B4 Jaw Crusher with Sliding Hopper
Sliding Hopper

Slide the main hopper, feeding unit and pre-screen back 600mm to easily access the pre-screen mesh and jaw crusher for maintenance and easier wear part replacement.

Keestrack B4 Jaw crusher Magnet Belt
Magnet Belt

Large hydraulic magnet belt for removing unwanted material after the jaw crusher. Hydraulically lifting so you can easily removed any unwanted material the may jam underneath it.

Keestrack Remote Control 10 Function
Remote Control

The Keestrack Remote gives the operator the ability to remotely adjust important crushing settings, track the machine during operation and emergency stop the machine all from his cab. The flexibility of the remote gives superior control and production.

Domex Steel Frame

Domex steel is both stronger and lighter than most other hardened steels used in machine frames. This makes the B4 lighter but still stronger than other models of jaws. It also makes it easier to transport.

Large PLC
Operator Friendly PLC

Featuring a large 7" LCD Screen the PLC unit is easy to navigate and use for making adjustments to the crusher and carrying out maintenance. It also has a simple start up and shut down sequence which sequentially starts up the machine and its components in the correct order.
