Impact crushers use impact force to crush materials, and you can use soft and medium-hard rocks with this machine. These crushers can complete primary and secondary crushing, making them suitable for applications in recycling and quarry industries.

Impactors come in two different types:

• Horizontal shaft impactors: Horizontal models feature a housing space that opens and adjustable curtains with a rotor assembly and hammer. These machines typically have a low-profile design and offer limited expansion area. When materials enter the crusher, they make impact with the hammers before quickly striking against the curtains and rebounding into the hammer circle.
• Vertical shaft impactors: Vertical models are typically tertiary crushers that require you to feed materials into the crusher's center through a tube. The material reaches a rotating table or rotor before accelerating and moving into the outer shell or anvil ring. Crushing occurs as the materials make impact with this surface.

Jaw crushers often perform primary crushing operations and are suitable for recycling, quarrying and mining operations. These machines are popular because they can crush almost any material type, including limestone, gravel, quartz, sand and granite. The materials are crushed between a moving jaw plate and a stationary plate as a pitman moves toward the stationary plate.

There are two main types of jaw models:

• Single-toggle: The pitman for these models is on an eccentric shaft, and a toggle plate holds the pitman in position at the bottom of the assembly. A rocking motion and eccentric motion cause a downward thrust.
• Double-toggle: These models have two shafts — a pivot shaft for the pitman to hang and an eccentric shaft to stimulate the toggle plates. The pitman swings toward the stationary plate rather than thrusting downward.

Sizers can crush soft to medium-hard materials, which can be wet, sticky, dry or slightly abrasive. Heavy mining applications often use these models. Primary sizers crush materials between rotating rolls, and material at the right size passes between them to minimize fine generation. You can achieve high capacities at low speeds with sizers as well as place fine materials into the machine, unlike jaw crushers and similar models that require pre-screening.

Also known as gyratory crushers, cone crushers have a primary shaft that creates a crushing motion. A moving inner member and fixed outer crusher piece make crushing operations possible. You can find roller-bearing and shaft-type cone crushers with similar functions. Generally, the main difference between the two types is a rotating wedge within roller-bearing models. These machines can complete secondary and tertiary crushing operations.

Cone crushers are typically used to reduce abrasive materials with considerable hardness, and they are excellent choices when impact crushers are not suitable. Mining operations and aggregate production teams often use cone crushers.

These crushers form a crushing chamber with revolving drums. You can adjust the gap between the drums, and you can find corrugated or smooth crushing options for the drum surfaces. These machines are dependable and rugged but may not offer the same productivity as other models because they handle a reduced volume. However, these models offer close product distribution, making them suitable for chip stone.
