The Four-Roll Crusher is a versatile fine-crushing powerhouse, ideal for materials with compressive strength below 300MPa and moisture content up to 30%.
Four-Roll Crusher
-
Ores & Construction Materials: Suitable for limestone, calcite, feldspar, quartz, river pebbles, and medium-hardness granite, as well as gypsum and quicklime.
-
Energy & Industrial Waste: A top choice for coal, coke, and coal gangue. It effectively processes steel slag, clinker, and C&D waste (bricks/concrete).
-
Chemicals & Specialty Scenarios: Handles fertilizers, salt, and ceramic raw materials. Due to its screen-free design and hydraulic protection, it excels with high-moisture sticky materials (like clay) and materials containing tramp metal.
Limitations: Not suitable for ultra-hard rocks (>300MPa), high-toughness materials (fiber/plastic), mud, or explosive substances.
Summary: For mineral, metallurgical, and recycling industries, the four-roll crusher is a stable, energy-efficient “all-rounder” for any material meeting its basic hardness and moisture requirements.
