A Secondary Impact Crusher: Everything You Need to Know
A secondary impact crusher is a machine that is used after the primary crushing process. This type of crusher is sometimes also referred to as an impactor or a horizontal shaft impact crusher (HSI). Secondary impact crushers are utilized for crushing materials that are not too hard and are used in a wide variety of applications, including mining, cement manufacturing, and aggregates production.
How Does a Secondary Impact Crusher Work?
The primary function of a secondary impact crusher is to reduce the size of materials that have already been crushed by a primary crusher. Secondary impact crushers typically have two or more aprons that are used to crush the material. The aprons can be adjusted to achieve the desired size of the final product.
Secondary impact crushers are designed to work with a variety of materials, including soft or non-abrasive materials like coal or limestone, as well as harder abrasive materials like granite or basalt. These crushers use a high-speed rotor that spins around and impacts the material being crushed against a series of anvils or impact curtains. The impact causes the material to be broken into smaller pieces that can then pass through the crusher’s grates.
Advantages of Secondary Impact Crushers
Secondary impact crushers offer several advantages over other types of crushers, including:
1. High Reduction Ratio: Secondary impact crushers have a higher reduction ratio than primary crushers, which means they can produce more uniform-sized materials.
2. Versatility: Secondary impact crushers are versatile machines that can be used in many different applications, including the production of aggregates, asphalt, and concrete.
3. Lower Operating Costs: Secondary impact crushers often have lower operating costs than primary crushers because they require less maintenance and have lower energy requirements.
4. Lower Capital Investment: Secondary impact crushers can be less expensive to purchase than primary crushers, making them ideal for smaller operations with limited budgets
