It appears you're asking about equipment used for crushing 300 tons of limestone. Limestone crushers are machines designed to crush limestone into smaller pieces or particles for various industrial applications. There are different types of limestone crushers, each with its own characteristics and uses. Here are a few common types of limestone crushers:
Jaw Crusher: A jaw crusher is a primary crusher that uses compressive force to crush materials. It is commonly used for coarse crushing of limestone. In the case of 300 tons of limestone, a jaw crusher could be used to break down the large pieces of limestone into smaller sizes.
Impact Crusher: An impact crusher uses impact force to crush materials. It is often used for secondary or tertiary crushing. Impact crushers can handle various materials, including limestone, and are effective for producing cubic-shaped particles.
Cone Crusher: Cone crushers are used for secondary and tertiary crushing. They operate by squeezing the material between an eccentrically gyrating spindle and a concave surface. Cone crushers are capable of producing fine and medium-fine materials.
Hammer Crusher: Hammer crushers use rotating hammers to impact and crush materials. They are commonly used for crushing softer materials like limestone. Hammer crushers can produce a wide range of particle sizes.
Roll Crusher: Roll crushers use compression to crush materials. They consist of two large rolls that rotate in opposite directions. Roll crushers are used for medium and fine crushing of limestone and can produce relatively uniform particle sizes.
The specific type of crusher you would use for crushing 300 tons of limestone would depend on the desired particle size and the characteristics of the limestone. Additionally, factors such as the feed size, moisture content, and required output size will also influence the choice of crusher.
It's important to consult with experts in the field and consider the specific requirements of your project when selecting the appropriate limestone crusher.
