Tracked Jaw Crusher: Why Heavy Matters

Maximizing Your Profit Per Manhour is The Aim of the Game 

With many jaw crusher manufacturers and no bad products, finding the best tracked jaw crusher is hard. Uptime, production, and low operating costs help you achieve the goal, and every jaw crusher manufacturer has a different solution to solve the same problem.

The RM J110X tracked jaw crusher is the heaviest jaw crusher in its class, which keeps you crushing in the toughest applications. This article helps you pinpoint why it is important to take a closer look at the jaw crusher box — the heart of the machine. 

Stalling Out, Blockages, and Downtime are Costing You 

If crushed material comes off the main conveyor belt, you are making money. Any downtime reduces your average production per hour and drives up our O&O costs. The more material you produce per hour, the cheaper your production costs. 


Common issues causing jaw crusher downtime: 

High reduction ratio

Crusher blockage with a piece that’s too big. 

Excessive rebar building a bird’s nest. 


Sticky and soft material doesn’t break easily. 

Weight and Strength Factors to Consider That Improve Reliability and Production Output 


1. Bolted vs Welded Crusher Design 

Whether a jaw crusher box is bolted or welded affects the rigidity of a construction. Welding is an art, especially when a welding robot can’t be used. A jaw crusher's compressing force creates many lateral forces that may cause bad welds to crack. A bolted crusher design reduces the number of stress points and allows you to use higher-grade side plates.


2. Heavier Flywheels Maintain More Inertia 

A heavy flywheel smoothens out peak loads enabling the engine and drive system to maintain the crusher speed. Without enough inertia, the jaw crusher can slow down or stop completely in hard rock material. If the crusher stalls out the crushing chamber may be filled with material. If you can't get the jaw going under load you are forced to shovel the crushing chamber out. Maintaining the crushing force, maintains capacity and increases fuel efficiency.


3. A Deeper Jaw Improves Crushing Action 

The depth of a jaw crusher affects its size and weight. Many mobile jaw crusher manufacturers struggle to build deep jaw crushers because of transport dimension requirements. The crusher depth affects the so-called nip angle, indicating how well the crusher grips and compresses the material. The better the nip angle, the better the crushing action. 

Also, the deeper the jaw crusher, the more reduction there is because the material is exposed to more crushing strokes before it leaves the crusher.

4. A Deflector Plate Reduces Belt Damages Through Rebar 

The deflector stops the steel from dropping straight through the jaw and reduces the risk of belt damage. It also aids in redirecting the rebar forward into the crusher exit channel.



5. Extended Cheek Plates Protect the Crusher Feed Chute

The cheek plates not only protect the crusher frame but also make the crusher feed chute much stronger and stop it from coming loose. The more the crusher chute is armored, the heavier it becomes. 

Conclusion: Jaw Crushers Have to Take the Brunt. Being Light Can be Expensive. 

Granted, tracked jaw crushers involve more than just the crusher box. Everything needs to operate in sync to achieve high production and low wear. However, the jaw box itself is the source and is exposed to the most operating stresses. Extra strength will help ensure the machine holds up in the toughest applications or overfeeding situations.

Novice and inexperienced operators tend to overfeed the crusher, resulting in lengthy downtime, risky blockage clearances, and a loss of money. All in all, a heavy jaw crusher will be more forgiving under tough operating conditions.
