Q: What types of roller crushers does HSM offer?
HSM’s roller crusher product line covers four main categories: roll crushers (smooth), double-tooth roll crushers, high-pressure grinding rolls (HPGR), and four-roll crushers. The roll crusher series is further divided into hydraulic and spring models.
Roll Crusher (Smooth Roll) : The roll surface is smooth or grooved, crushing primarily through compression and grinding. Suitable for medium and fine crushing of medium-hard materials with uniform discharge size, capable of processing materials with compressive strength up to 250 MPa. HSM roll crushers are available in hydraulic and spring series. Spring roll crushers have a simple structure, using spring compression to provide crushing force and allowing roll gap release when encountering uncrushable objects. Hydraulic roll crushers use a hydraulic system for precise roll gap adjustment with automatic overload protection – when uncrushable material enters, the rolls automatically retract.

Double-Tooth Roll Crusher (Toothed Roll) : The roll surface features teeth, crushing primarily through splitting and tearing action. With a high reduction ratio, it is suitable for coarse and medium crushing of brittle and soft materials, widely used in coal, metallurgy, mining, chemical, and building materials industries. Tooth profiles can be customized according to material characteristics, such as trapezoidal teeth.
Double Tooth Roll Crusher
High-Pressure Grinding Roll (HPGR – Roller Press) : Applies high pressure through a hydraulic system, using quasi-static pressure and interparticle bed crushing. Material particles are crushed by mutual compression within a dense bed, rather than single-particle crushing. Suitable for fine crushing and pre-grinding of metal ores (iron, copper, gold, etc.), generating micro-cracks that reduce downstream ball mill energy consumption, achieving “more crushing, less grinding.” The roll surface typically features studs or hardfacing wear layers to handle highly abrasive materials, suitable for large-scale industrial production.
High Pressure Roller Crusher
Four-Roll Crusher : An extension of the roll crusher and double-tooth roll crusher, combining the advantages of both. Two pairs of rolls are arranged in series – the upper pair performs coarse crushing, the lower pair performs fine crushing. Suitable for feed sizes under 90mm with product requirements ranging from 100 mesh to 5mm in ultra-fine crushing applications.
Four-Roll Crusher
Strong Double-Roll Crusher : A special type of toothed roll crusher that integrates screening and crushing functions, using combined shearing and tensile forces to break material. Suitable for raw coal (with gangue) crushing in large coal mines or coal preparation plants.

Different types of roller crushers have different strengths in terms of applicable materials, discharge size, and capacity range. HSM provides a range of configuration options from high-end to standard models based on customer requirements.
