Description
The FF-series fixed pulveriser is a heavy-duty hydraulic attachment designed to bite, crush, and progressively “process” demolition debris rather than simply tear it down. Mounted to an excavator, it works through a powerful jaw action that grips concrete and masonry, breaks it into manageable fragments, and exposes embedded reinforcement so material can be handled, sorted, and recycled more efficiently. It’s particularly well suited to the phase after the main structure has been brought down—when the job shifts to reducing slabs, walls, and rubble so it can be loaded out and repurposed or disposed of.

Sales Manager
I joined Approved Hydraulics in November 2014 at the age of 18, starting as a Stores Apprentice with responsibility for stock control, goods management, and purchasing support. This role gave me a strong grounding in our products, processes, and the operational side of the business.In 2017, I transitioned into a full-time sales position and have been actively involved in day-to-day sales activities ever since, supporting customers, managing enquiries, and developing product and commercial knowledge across our range.In 2025, I was promoted to Sales Manager. In this role, I lead a team of six sales colleagues and oversee the daily operations of the sales function, ensuring customer enquiries are handled efficiently, service standards are maintained, and the team continues to deliver consistent results and strong customer relationships.
FF Series Pulveriser
In use, the tool is aimed at ground-level demolition and “clean-up” work: taking down remaining sections of surrounding walls and medium-height vertical elements, breaking pavements and floor plates, and separating steel rebar from crushed concrete as it goes. Because it’s a fixed (non-rotating) pulveriser, operators typically position the excavator body and boom to line up each bite, then use repeated clamp-and-crush cycles to progressively reduce material size. This makes it especially effective where consistent, high-force crushing is needed and where the end goal is a more uniform, transport-friendly product for recycling streams.
Structurally, the FF-style design focuses on durability and protected power delivery: it uses a robust, abrasion-resistant steel frame (including Hardox-grade wear material) intended to withstand constant impacts and abrasive concrete dust. The hydraulic cylinder is arranged in an inverted/protected configuration to reduce exposure to knocks and debris while still delivering high clamping force at the jaw tips. Many configurations also incorporate a speed-valve function to recover and reuse oil during parts of the cycle, improving jaw closing speed and overall productivity when you’re repeating thousands of bites across a site.
From a maintenance and uptime perspective, these grabs are built around replaceable wear components so the tool can stay tight and effective as it ages. Interchangeable teeth, tooth plates, and bolted wear plates allow the contact surfaces to be renewed without rebuilding the entire jaw, while interchangeable blades/cutting edges help keep rebar separation and sizing performance consistent. The series is offered across multiple sizes to match a wide spread of excavator classes, allowing contractors to scale the same “crush and separate” approach from smaller carriers up to heavy demolition machines.

Best practices for keeping your hydraulic system running efficiently.
How do you check oil condition?
Visual inspection for discoloration, foaming, or particles Lab analysis provides a detailed breakdown of contamination, viscosity, acidity, and wear metals This helps determine oil life and potential system issues.
How do you dispose of hydraulic oil?
Collect used oil in approved containers Take it to a licensed waste oil recycling or disposal facility Never pour it into drains or the environment — it’s illegal and harmful.
How do you prevent contamination?
Use sealed containers and clean tools Always clean hose ends and fittings before connecting Install high-quality filtration on return lines and reservoirs Avoid opening the system unnecessarily
How do you store hydraulic hoses?
In a clean, dry, and cool environment Away from direct sunlight, heat sources, and ozone-producing equipment Preferably stored horizontally on racks to prevent kinking or deformation
How often should filters be changed?
At regular service intervals or when a clogging indicator signals high restriction. It’s best to change filters before they reach full capacity to avoid bypassing dirty fluid.
How often should hydraulic oil be changed?
Typically every 2,000 operating hours, or as recommended by the equipment manufacturer. Factors like system cleanliness, load, and temperature can influence intervals. Always verify with oil analysis if unsure.
What is a breather cap?
A breather cap allows air to enter or exit the reservoir as fluid levels change, without letting contaminants in. Some include filters to trap airborne particles or moisture.
What is preventive maintenance in hydraulics?
Scheduled checks and service tasks (e.g., inspecting hoses, changing filters, checking oil) to prevent unexpected failures, extend system life, and reduce downtime.
What tools are used in hydraulic diagnostics?
Pressure gauges to check line pressure Flow meters to measure flow rate Infrared thermometers or thermal cameras to detect hotspots Ultrasonic leak detectors to find air or fluid leaks Test kits for oil sampling
Why should systems be flushed?
Flushing removes contaminants like metal shavings, dirt, or water — especially important after repairs, system assembly, or oil changes. It helps prevent premature wear and failures.
