The PC hammer crusher is designed for crushing materials with feed sizes ranging from 200 mm to 300 mm, producing an output size of less than 30 mm. The output particle size can be adjusted via the grate bars at the discharge opening. With an hourly production capacity of 3–95 tonnes, it is capable of meeting a wide range of crushing requirements.

Capacity: 3-95 t/h
Feed Size: ≤300 mm
Output Size: ≤25-30 mm

The PC series hammer crusher combines the advantages of both traditional hammer crushers and impact crushers. Hence, it is also known as a “hammer impact crusher.” It primarily utilizes high-speed rotating hammers to strike and break materials. The equipment features a simple structure, a high crushing ratio, and high production efficiency. It is capable of both dry and wet crushing operations. Furthermore, the gap between the grate bars can be adjusted according to user requirements, allowing for the modification of the output particle size to meet diverse operational needs.

Sandreck’s PC hammer crusher integrates crushing and shaping functions. In stone crushing production lines, it is frequently employed for secondary fine crushing and material shaping. The output particle size can be flexibly adjusted within the 0–30 mm range. It is primarily designed for the medium and fine crushing of moderately hard or brittle materials—such as gypsum, salt, coal, brick, tile, and limestone—across industries including cement, chemicals, power generation, and metallurgy.

PC Hammer Crusher Working Principle

A hammer crusher primarily utilizes impact energy to break down materials. During operation, an electric motor drives the rotor to rotate at high speed. As material enters the crushing chamber, it is subjected to impact, shearing, and tearing by the rapidly rotating hammers, which causes it to break apart. Simultaneously, the force of gravity, combined with the action of the high-speed hammers, propels the material toward the baffles lining the crusher housing.

Throughout this process, the material particles also collide with one another. Once broken, the material falls downward. A screen plate is positioned beneath the rotor; material that is smaller than the screen apertures passes through and is discharged. Coarser particles—those larger than the screen openings—remain on the screen plate, where they continue to be subjected to the impact and grinding action of the hammers. Once the material reaches the desired particle size, it passes through the screen plate and is discharged.

Advantages of PC Hammer Crusher

1) Stable, High-Yield Performance

Features a large feed opening and an optimized crushing chamber design, allowing for a greater volume of material intake. This results in a 30% increase in production capacity while minimizing the content of flaky or elongated particles.

2) Adjustable Particle Size

Equipped with a spring or hydraulic adjustment mechanism, allowing for precise control of the output particle size to meet diverse customer requirements.

3) Excellent Wear Resistance

Components such as the hammerheads are crafted from high-chromium alloy composite materials, and the rotor is reinforced with wear-resistant protective rings. This ensures low wear on consumable parts and an extended service life.

4) Versatile Functionality

This PC hammer crusher combines fine crushing and shaping capabilities. It offers a high crushing ratio, a high yield of finished product, and produces material with an excellent, uniform shape.

PC Hammer Crusher Applications

Mining and Metallurgy: This equipment is used to crush various types of ore—such as limestone, granite, iron ore, basalt, and river pebbles—and is also employed in mineral processing workflows, including those for hematite.
Construction Materials and Engineering: The PC hammer crusher is a key piece of equipment for the production of construction aggregates and manufactured sand. It is widely used in projects such as expressways, high-speed railways, bridges, tunnels, municipal infrastructure, real estate development, and the construction of hydroelectric power stations.
Environmental Protection and Resource Recycling: Hammer rock crushers can be used to process solid waste—such as construction debris and concrete—into recycled aggregates.
Energy and Water Conservancy: This equipment is used to produce materials like quartz sand, which are required for the construction of hydroelectric power stations and for desulfurization processes in power plants.
Other applications include aggregate quarries, coal mining, concrete batching plants, and the production of dry-mix mortar.
