Frequently asked questions

The difference is substantial at the operational level. Crunchy Plus is a medium-large construction site jaw crusher: it weighs about 800 kg, requires positioning by excavator, and can crush up to 6–7 m³/hour of material. Crunchy Compact is designed for renovations and on-site work: it weighs 120–145 kg, moves on wheels, is powered by 230V single-phase electricity, and produces approximately 1 m³/hour. These are machines with different operational objectives, not versions of the same product.

If you mainly work with concrete, bricks, ceramics, screeds, and common construction materials, the Compact Standard is sufficient. If, on the other hand, you work in the stone industry or need to crush marble, granite, basalt, quartzite, porphyry, or quarry waste, you should opt for the Compact Stone, which is specifically designed for harder and more abrasive materials. Marble workers, for example, are exactly the target market for the Stone version.

Yes, but with an important technical clarification: Crunchy machines process the mineral part of reinforced concrete, simultaneously freeing the steel. They do not crush the iron: they mechanically separate it from the concrete. The output material is crushed aggregate; the bars or electro-welded mesh are ejected intact.

Crunchy crushers work exclusively with rigid and brittle mineral materials, i.e., materials that break under compression without deforming or bending. They are not compatible with bituminous materials (asphalt and waterproofing membranes), plastic and elastic materials, pure metals, or muddy or wet materials. Loading unsuitable materials compromises the jaws and invalidates any productivity assessment.

Yes. The Crunchy Plus is compatible with flat glass and thick glass. The Compact Stone also handles tempered glass thanks to the greater strength of its frame.

The Crunchy Plus requires 400V – 50Hz three-phase power for both the machine body (4 kW motor) and the Plus conveyor belt (1.1 kW motor). It cannot be used with standard domestic sockets: a three-phase panel is required on site.

Yes. Crunchy Compact is powered by 230V single-phase – 50Hz, the standard construction site power outlet. It is also available in a version with a 2.4 kW 4-stroke combustion engine for construction sites without access to electricity.

The Crunchy Plus crushing chamber has an opening of 410 x 235 mm. This determines the maximum size of the input material: blocks or elements larger than these dimensions must be pre-reduced before feeding.

The machine’s dimensions are 1,230 x 900 x 1,910 mm (depth x width x height), with a weight of 800 kg. Adding the Plus conveyor belt (3,000 x 400 mm, 120 kg), the complete configuration requires a working area of approximately 4.5 m in length.

The gap between the jaws is continuously adjustable from 7 to 40 mm. The output grain size is coarser than that of Crunchy Compact: suitable for sub-bases, fillings, and backfilling, less suitable for applications requiring fine, calibrated aggregate.

Crunchy Compact has 6 adjustment positions for the slot, ranging from 6 to 22 mm. The version with a vibrating sieve allows for even finer and more controlled grain sizes, directly separating the material for wheelbarrow or bagging. It is the only model in the range with this feature.

The declared noise level is less than 75 dB(A), which remains within standard construction site operating parameters. This figure varies depending on the material being processed. However, it remains an industrial machine, so operators must be equipped with the PPE required by law.

Yes. Both lines are CE compliant. Crunchy Compact is also a patented product. All structural steelwork is made from HARDOX® steel, certified “HARDOX In My Body,” a guarantee of the quality of the wear-resistant steel used.
