As a special organic mineral resource, peat creates tough crushing challenges—challenges that a standard sand crusher, designed for hard, dry aggregates, can barely tackle. Natural peat has a water content of 60%–80%; its high humidity makes it stick to a sand crusher's inner walls, causing agglomeration and blockage. This not only slashes the sand crusher's efficiency but also hikes cleaning and maintenance costs, as workers must frequently disassemble parts to remove caked peat.

Peat's strong viscosity (from colloids like humic acid) leads to "clumping" after processing. Traditional crushing equipments work for stone but presses peat into lumps, the material fails to reach the uniform particle size needed for agricultural substrates or organic fertilizers. Adding to this, peat's residual plant fibers form an interwoven network; a traditional sand crusher's weak shearing force can't cut these fibers, leaving long clumps in the final product that ruin subsequent processing quality. These issues make peat crushing an industry-wide problem—over-crushing damages peat's organic structure, while under-crushing misses standards. Thus, replacing the sand crusher with a specialized VSI crusher (Vertical Shaft Impact Crusher) is critical to breaking this bottleneck.

the VSI crusher uses a vertical shaft layout with a high-speed rotating impeller (1200–1800 r/min) and fixed liners. Its "kinetic energy impact" principle—accelerating peat via the impeller, then projecting it onto liners for violent collision—avoids the adhesion that plagues sand crushers.

To tackle peat’s unique viscosity and fibrous nature, the VSI crusher features a dual-mode design—“rock-on-rock” and “rock-on-iron”—a key advantage no ordinary sand crusher provides. In “rock-on-rock” mode, the VSI crusher uses peat particles’ mutual collision to crush, minimizing equipment wear and preventing peat adhesion, which keeps the VSI crusher running smoothly. For high-fiber peat, the VSI crusher switches to “rock-on-iron” mode, using durable alloy liners to enhance shearing force, ensuring efficient breakdown. This tailored design makes the VSI crusher far more effective for peat than sand crushers.

This dual mechanism lets the VSI crusher overcome peat's viscosity and fiber tangles. It enables efficient crushing of high-humidity, high-viscosity peat, making the VSI crusher, not the traditional processing equipment, the go-to equipment for peat processing.
