What is a cone crusher and what stones are it mainly used to crush?

A cone crusher is a type of heavy machinery used in the crushing industry. It works by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. The material is reduced in size and discharged through the bottom opening of the machine. Cone crushers are designed to process a variety of materials, including:

1. Granite - Known for its hard texture and high abrasiveness.
2. Basalt - A tough and dense material that often requires a powerful crushing machine.
3. Limestone - Commonly used in construction and road-building because of its relatively lower hardness and ease of crushing.
4. Quartz - A hard, crystalline mineral often requiring robust crushing equipment.
5. Iron ore - Known for its hardness and requires powerful crushers for size reduction.

Additionally, cone crushers are commonly used in mining, quarrying, and recycling applications because of their ability to produce uniformly sized material and their versatility in handling various types of rock and ore.
