Heavy hammer crusher is a medium-to-large mining equipment that uses the impact force of high-speed rotating hammers to crush materials. It is suitable for medium and fine crushing of medium-hard materials with a compressive strength of ≤200MPa (such as limestone, bluestone, coal gangue, etc.).

Baichy PCZ series heavy hammer crusher is a single-stage crushing solution engineered for medium-hard bulk materials with compressive strength ≤200 MPa — including limestone, bluestone, dolomite, coal gangue, and shale. By integrating primary impact crushing and secondary refinement into one machine, the PCZ series replaces the traditional jaw crusher + impact crusher two-stage circuit, reducing equipment footprint by ~40% and total installed power by ~25%.
Available in 7 models from PCZ0808 (50-90 t/h) to PCZ2016 (500-800 t/h), all units feature high-torque heavy-duty rotors, multi-alloy composite cast hammers with HRC62+ surface hardness, hydraulic-assisted unpacking for sub-5-minute maintenance access, and wavy grate bars designed to minimize material blockage.

PCZ heavy hammer crusher completes primary and secondary crushing in a single pass — feed ≤1200mm is reduced directly to finished product (≤30mm, adjustable) without a secondary crusher or return circuit.

• Dual motor drive with hydraulic couplings — smooth full-load start, reduced grid surge
• Multi-alloy cast hammers (Cr-Mo-V metallurgy): HRC62+ surface hardness, ductile core
• 360° reversible mounting — rotate worn face to fresh face, double service life
• 35-120 kg per hammer, delivering 15,000+ joules per impact at rated RPM
Conventional crushers: 2-4 hours to access internals. PCZ hydraulic shell opening completes the full cycle — open → replace hammers → close — in under 5 minutes, yielding 200+ extra operating hours per year.
Heavy-duty hammer crusher is mainly applied in the industries of mines, metallurgy, building materials, road construction, railway building, water conservancy, cement, sand, coal, chemical engineering and electricity.
Large pieces of material (such as granite with a diameter of ≤1200mm) are thrown in from the feed port and instantly hit by the hammer on the rotor at a linear speed of 35-55m/s.
Impact force calculation: Assuming the hammer weighs 100kg and the rotation speed is 1200r/min, the kinetic energy of a single impact can reach 15,000 joules (equivalent to a 1.5-ton object falling from a height of 1 meter).
The material that has not been crushed once hits the serrated impact plate, and through rebound, it forms a "hedge crushing" with the subsequent hammer, thereby improving the fine crushing rate.
Industry skills: The angle of the impact plate is usually designed to be 30°-45°. The smaller the angle, the longer the material stays and the finer the finished particle size.
The crushed material is screened by the grate bars, and qualified particles (≤ set size) fall down, while oversized particles continue to be "reprocessed" by the hammer head.
Innovative design: Some high-end models use "wavy grate bars" to reduce the risk of blockage by increasing the screening area.

A PCZ heavy-duty model has a thicker rotor, heavier hammers, a larger feed opening (up to 1,000–1,500 mm) and much higher capacity (up to ~3,000 t/h). It is designed for one-stage primary crushing of large lumps, while the PC series is used for secondary/fine crushing at lower capacities.
Yes for limestone, coal, shale and other medium-hard brittle materials. Because of its high reduction ratio (20–25:1), a PCZ can take run-of-mine ore directly and deliver final product in a single pass, roughly cutting equipment and installation cost by 30–40% compared with a two-stage circuit.Henan Fote Machinery Co., Ltd.
Output size is controlled by changing the gap between the grate bars at the bottom of the rotor. A wider gap gives coarser product and higher capacity; a narrower gap gives finer product but lower throughput. You can swap or adjust grate bars during maintenance.
The high-wear parts are the hammer heads (hammers), grate bars / sieve plate, and breaker/liner plates. Hammers are reversible, so flipping them roughly doubles service life. Use high-manganese or high-chromium alloy hammers for abrasive feeds.
Generally not recommended as the primary crusher. Granite, basalt and river rock are highly abrasive; hammers and liners wear very fast and running costs become uneconomical. For these materials, a jaw crusher + impact crusher (or cone crusher) circuit is a better choice.
