 MACHINE BENEFITS

All Keestrack Diesel-Hydraulic mobile machines integrate their signature Load Sensing Pump Technology. Whilst traditional mobile plant use gear pumps and restrictors, Keestrack's Load Sensing Pumps do just as the name says, they sense how much fluid is needed to run the plant to what the operator has configured.

Compared to the aforementioned gear pumps, Load Sensing Pumps save businesses up to 25% on their Diesel Burn, a significant economic and environmental saving, best yet their just as reliable as the traditional gear pump and have reduced wear as hydraulic componentry is not oversupplied.

Keestrack is one of the foremost leaders in Quarry equipment electrification. Their E-Series equipment features an all-electric drive system and an integrated Diesel Generator for off the grid running.

By utilising E-Motors over traditional hydraulic motors and engine direct drives, E-Series machines have higher output power with less energy consumption in addition to a longer operational life span.

The E-Series onboard Diesel Genset provides the necessary power to run the machine off the main grid and delivers a 50% fuel saving compared to the equivalent Diesel-Hydraulic machine, as an all-electric drive system is more efficient resulting in less generated energy being lost.

When set up via 3-phase grid connection E-Series machines reach another level of cost and carbon reduction. Powered directly from the grid the energy cost is 70% less than the equivalent Diesel-Hydraulic machine, and the equipment carbon footprint is further reduced to that of the grid.

E-Series Machines

Keestrack's Wireless Remote offers more than just a convenient way to start and stop the machine, it's a fully-featured platform giving operators full control of the machines and its functions from the comfort and safety of the cab.

The Wireless Remote enables start and stop, tracking,and adjustment of machine-specific parameters like C.S.S on a Jaw and Aprons onan Impactor. It also includes an emergency stop switch, making it an extension of the machine's safety systems.

The Wireless Remote has 2-way communication with the plant, enabling the remote to display the machines current configuration and what the operator is adjusting.

Like your cellphone, the Wireless Remote is USB rechargeable and is securely paired with the machine. Built from a weather-sealed polycarbonate hardshell it also incorporates a rubberised grip for impact protection.

Wireless Remote Control

The Keestrack-er Remote Telematics System is an advanced monitoring system that allows monitoring and remote adjustment of any PLC monitored components.

The PLC is connected to a cellular telematics modem, the unit stores and transmits the data to the Keestrack-er cloud, where the owner or service agent can access the telemetry.

If an area with no signal the telematics unit will upload the stored data once back in range. Keestrack-er offers some distinct advantages for fleet management. Allowing managers to see where the equipment is positioned on the site via a map overlay and how productive the mobile plant has been.

Metrics like fuel usage, engine load, crushing/screening parameters, conveyor parameters are all monitored and recorded, allowing managers to see real-time and historical data.

In addition to tracking a mobile plants productivity, the Keestrack-er Telematics System enables equipment to be remotely diagnosed and adjusted by Equip2, helping solve production issues using data.

Large Jaw Inlet

The B4 has the largest Jaw inlet in its weight class (30 tonnes), rivalling competing Mobile Jaw Crushers found in 40-tonne machines. The Jaw inlet size of 1,100mm x 700mm enables larger material to be crushed and sized in a smaller machine footprint. The Jaw Inlet also benefits the B3's Jaw size, as the larger inlet means the Jaw is larger and heavier and thus has better compression characteristics during the closing swing.

N.S.S Jaw Safety System

Keestrack patented N.S.S (Non-stop overload Safety System) Jaw protection mechanism is a collection of components and systems integrated into the Jaw that protects against overload or damage to the Jaw. During a crushing pass or closed swing if over compaction or an uncrushable material enters the chamber this can cause a regular Jaw crusher to overload resulting in damage to the plates, structure, or hydraulic system; N.S.S prevents this.

Vibrating Feeder With Active Pre-Screen

With an adjustable vibrating double-deck screen built-in to the feed hopper, unwanted fines can be removed from the feed prior to entering the crushing chamber. Capable of sorting through high volumes the double-deck aids the total throughput of the right material and prevents possible material compaction in the chamber particularly during wet or sticky material crushing.

Reversible Jaw

The B3's Jaw can be run in reverse, aiding the clearing of uncrushable materials that have entered the chamber or for use during crushing operations to produce different material effects, like 'fluffing' asphalt.

Specialised Pivoting Plate

A specialised pivot plate gives the B3's Jaw mechanism an aggressive movement aiding its ability to rapidly crush tough material throughout its C.S.S range.

Automatic Wear Recovery

Part of one of the benefits to N.S.S, the hydraulic cylinders that electronically control the operators set C.S.S can also perform automatic Jaw plate wear recovery every 50 hours. This function can be completed manually or adjusted to suit the needs of the operation, to continually ensure the correct C.S.S is met even after long periods of crushing.

I did compare other plants and pricing, but I liked the features the B4 had, practical ones that were common-sense. Like the Jaw protection system, radio remote and PLC unit, all things that make it easy to use.

How does a Jaw Crusher work?

Jaw Crushers or mobile single toggle jaw's specifically, work by compressing material between two wear plates, causing the material to fracture. The Jaw plates are angled so that the distance between them decreases towards the bottom, allowing the material to break down during the crushing motion, which like the name suggest is like jaw movement. Once smaller enough the material passes the chamber onto the main conveyor. For an in-depth breakdown see this article.

Can you guarantee the B4's performance?

In general, this can be hard to do, but we can provide a full Return on Investment summary of the machine including all associated costs to run it, staffing, wear parts, insurance, finance, and then expected production and sales. All this information is pulled from our customer real-life performance of this machine, and then your production goals and material. We also can offer subject to trial, allowing you to see the machine perform and meet our ROI estimate, eliminating the risk of getting a dud.
