For crushing 10mm to 50mm stone, a jaw crusher or an impact crusher can be a good choice depending on the specific requirements of the application.

A jaw crusher is typically used for primary crushing, and can crush large stones into smaller sizes. It operates by compressing the stone between a stationary jaw and a moving jaw, which moves back and forth to create a squeezing motion. Jaw crushers are versatile and can handle a wide range of materials, making them a good choice for crushing stones of various sizes.

An impact crusher, on the other hand, is a secondary crushing machine that is designed to break down smaller stones. It uses a rotor with high-speed rotating blades to strike the stone and break it into smaller pieces. Impact crushers are often used in quarrying and mining operations to break down larger stones that cannot be handled by jaw crushers.

In general, both jaw crushers and impact crushers can be effective for crushing 10mm to 50mm stones, but the choice ultimately depends on the specific needs and requirements of the application.
