On demolition jobs, operators often focus mainly on crushing force when trying to improve processing speed. If material is not breaking down quickly enough, the usual response is to apply more pressure or repeat the crushing cycle longer.
But the entry point of the crush has a major influence on how efficiently concrete breaks apart.
Where the jaws first engage the material changes how force travels through the structure when using concrete pulverisers.
Concrete does not break evenly across its entire surface.
Different sections carry load differently depending on reinforcement, thickness and existing stress within the structure.
If the pulveriser enters through a stronger or more compact area, the material absorbs more resistance before cracks begin developing properly.
A weaker or more exposed entry point allows the crushing force to spread through the structure more effectively.
You position the jaws onto a solid central section of concrete.
The pulveriser closes and surface cracking begins, but the structure resists deeper breakdown. The operator then applies more pressure or repeats the cycle multiple times before the material separates fully.
Now compare that to entering from an exposed edge or previously weakened section.
The crack travels faster through the structure and larger sections begin separating earlier in the cycle.
Instead of fighting the full strength of the concrete at once, the material starts failing progressively from the entry point onward.
Poor crushing entry points create:
Over time, this slows demolition progress and increases unnecessary machine movement between crushing positions.
When the pulveriser enters through a more responsive section of the structure, the crushing force transfers more efficiently through the material.
Instead of concentrating resistance in one compact area, the break progresses naturally through weaker sections first.
You will notice:
A TocDem setup working from the correct crushing entry point allows concrete pulverisers to maintain more efficient material processing throughout the job.
Assess the structure carefully before starting the crushing cycle.
This allows the pulveriser to work with the structure instead of against its strongest resistance points.
Operators naturally focus on crushing pressure because it is the most visible part of the process.
If concrete resists breakdown, it feels logical to apply more force.
But incorrect entry positioning often creates unnecessary resistance before the crushing cycle has a chance to develop properly.
Machine control and jaw positioning both affect crushing efficiency.
Key factors include:
Even a well-maintained TocDem unit will lose efficiency if the crushing cycle begins from a poor entry position.
Does entering from edges always improve crushing speed?
Not always, but exposed or weakened sections usually allow force to transfer more effectively.
Can higher crushing pressure compensate for poor entry points?
Only partially. Incorrect positioning still creates unnecessary resistance through the structure.
Is entry point selection more important on reinforced concrete?
Yes. Reinforced structures respond very differently depending on where the crushing cycle begins.
Efficient crushing starts with choosing the correct entry point.
Working from responsive sections of the structure improves breakdown speed, reduces repeated crushing cycles and keeps demolition processing moving more efficiently.
