Filter Cake Won’t Break Apart, Drying Gets Stuck? NHD’s Crusher Is Built for “Stubborn Filter Cakes.”

In many industrial plants, filter cakes discharged from filter presses tend to form large, sticky agglomerates that cling together—an issue that has long troubled operators.
On the surface, it may seem like a simple problem of “not breaking apart,” but in reality, it directly affects the efficiency of the entire downstream process.

This challenge is especially common in new energy, hydrometallurgy, and non-ferrous metal industries, where filter cakes often have high moisture content and strong adhesion. When fed directly into drying systems, plants frequently face:

• Poor feeding due to oversized cake lumps

• Low drying efficiency and high energy consumption

• Frequent manual intervention and increased safety risks

• Blockages and unplanned downtime in downstream equipment

To solve this critical bottleneck, NHD has custom-developed a filter cake disintegrating crusher specifically for end users.

Designed for Discharged Filter Cake — Solving “Won’t Break” in One Step

This crusher is not a conventional crushing machine. It is purpose-built for filter cakes discharged from filter presses and tailored to real operating conditions:

• Effectively breaks up agglomerated and sticky filter cakes

• Produces a more uniform particle size suitable for direct feeding into dryers

• Reduces manual handling and improves continuous, automated operation

Whether dealing with high-moisture filter cakes or fine, sticky materials commonly found in the new energy sector, the machine delivers stable and controllable disintegration performance.

Proven in Overseas Projects: Successfully Replacing Imported Equipment

NHD’s filter cake crusher has already been exported overseas and has been operating continuously for more than six months in a project in the Demokratische Republik des Kongo, where it directly replaced imported equipment.
Under long-term continuous operation, it has demonstrated reliable performance, clear disintegration results, stable operation, and easy maintenance. Overall performance has exceeded customer expectations and earned high recognition from on-site users.

Particularly Suitable for These Industries

If your project involves the following conditions, this equipment is especially worth considering:

• New energy materials (cathode/anode materials, intermediates)

• Non-ferrous metal hydrometallurgy

• Continuous processes combining filter press and drying

Filter cake no longer needs to be a bottleneck—it can become a fully controllable process step.
