HS Impact Crusher (Horizontal Shaft Impactor)

The Rockwell Crusher HS series is a horizontal shaft impact crusher for secondary crushing and gravel production. It breaks rock with rotor hammers and impact plates and produces cubical aggregate for concrete and asphalt. The HS series is built in four models, HS7, HS10, HS14 and HS16, with capacities from 70 to 400 tons per hour.

Application

Secondary crushing of limestone, dolomite and medium-hard rock in sand and gravel plants, concrete and asphalt plants and quarries. It usually follows the jaw crusher, and its product goes to the screen or to the rock on rock VSI crusher for sand.

Built by Rockwell Crusher

Built in the Rockwell Crusher workshop in Shahr-e Qods, Tehran, Iran, so wear parts such as hammers and impact plates are always available, with installation, commissioning and after-sales service.

Working Principle

How Does an HS Impact Crusher Work?

FeedingRock enters the crushing chamber through the feed chute.
Hammer impactThe rotor spins at high speed; the hammers break the rock and throw it toward the impact plates.
Impact platesRock breaks further as it hits the impact plates and other particles.
DischargeCrushed material leaves from the bottom. Product size is set by the gap between the impact plates and the rotor.

Models

HS Impact Crusher Models and Capacity

Actual capacity depends on rock type and hardness, feed gradation and impact plate setting.

Model	Capacity (t/h)	Best for
HS7	70–100	Small and medium plants
HS10	150–180	Medium sand and gravel plants
HS14	200–220	High-capacity plants
HS16	330–400	Very high-capacity plants and large quarries

Features

Features of the Rockwell Crusher HS Impact Crusher

Cubical grain shape

Impact crushing produces cubical aggregate suitable for concrete and asphalt.

High reduction ratio

Rock is reduced to a much smaller size in one stage, sometimes removing the need for an extra crushing stage.

Adjustable product size

Product size is set by changing the gap between the impact plates and the rotor.

Easy wear part replacement

Hammers and impact plates are replaceable and supplied by Rockwell Crusher.

FAQ

Frequently Asked Questions About the HS Impact Crusher

What is an HS impact crusher?

An HS impact crusher is a horizontal shaft impact crusher, known in Iran as a Behringer crusher. A high-speed rotor with hammers strikes the rock and throws it against the impact plates (anvils), where it breaks further.

What is the capacity of the Rockwell Crusher HS series?

The HS series is built in four models: HS7 with 70–100, HS10 with 150–180, HS14 with 200–220 and HS16 with 330–400 tons per hour.

Which rocks is a horizontal impact crusher suitable for?

It works best on soft to medium-hard rock such as limestone, dolomite and river gravel. For very hard and abrasive rock such as granite and basalt, a cone crusher is usually the better choice.

What is the difference between an HS impact crusher and a rock on rock VSI crusher?

The HS crusher has a horizontal shaft and crushes with hammers; it is used for secondary crushing and gravel production. The VSI has a vertical shaft and crushes rock against rock; it is used in the final stage for manufactured sand.
