This is the main part of the HSI crusher. It holds the blow bars and rotates at a high speed, being driven by a pulley connected directly to the engine.

Blow bar, Hammers Wear parts inserted into the rotor which impact the rock to cause breakage. These can be replaced when they are worn down. There are two different options:
4 high blow bars
2 high and 2 low blow bars
Some older design crushers had a 3 bar rotor.

Aprons Primary and Secondary aprons are used to reduce rock down to the required product size.

Aprons Liners that are generally fitted to the end of aprons (which are replaceable wear parts) to ensure the apron settings can be maintained.

Side liners Sometimes called frame liners, these are used on the inside of the impactor body to protect it from wear.
