First of all, rocks and stones are evenly sent to the jaw crusher by the vibrating feeder for primary crushing, and then the rough materials are conveyed to the impact crusher by the belt conveyor for the further crushing. The vibrating screen separates the crushed stones or rocks according to their size, and the stones with larger size will be broken again by the impact crusher.
Crushing is a physical process.
1. Crushing is a physical process.2. Burning is a chemical process.
Jaw crushers are mainly used for primary crushing and a cone crusher is suitable for crushing various mid-hard and above mid-hard ores and rocks. The jaw crusher is widely used in the primary crushing or secondary crushing process in a stone production line. The jaw crusher is a high-performance crushing machine and it's the first choice for the rigid, strong abrasive materials crushing process. The cone crusher is used in the secondary and tertiary crushing process.
Early people likely chose stones to make their first tools due to the availability and hardness of stones. Stones were readily found in their natural environment and could be shaped into sharp edges for cutting and hunting. Stones provided a practical and durable material for crafting various tools necessary for survival.
It depends on how you crush it. If using ultrasound from outside the body, the procedure is called ESWL - extracorporeal sound wave lithotripsy . The machine used to perform this procedure is called a Lithotriptor. +++ It doesn't "crush" the calculus, but cause it to disintegrate by cavitation induced by extremely high frequency sound-waves - basically they shake it to bits.
Lithotripsy is a general term meaning stone crushing, and can be applied to the destruction of both kidney stones and gallstones.
To break large stones into small materials. There are many kinds of crusher such as jaw crusher, impact crusher, cone crusher, mobile crushing plant, etc.
because of the two plates crushing together, it forms earthquake
It is a physical process.
Stone crushing plant is made up of vibrating feeder, jaw crusher, impact crusher, vibrating screen and so on.First of all, the raw materials are evenly sent to the jaw crusher by the vibrating feeder for primary crushing, and then the rough materials are conveyed to the impact crusher by the belt conveyor for the further crushing. The vibrating screen separates the crushed stones according to their size, and the stones with larger size will be broken again by the impact crusher.
Just as stones come in different sizes and shapes the also come in different 'hardness'. Soft stones like sandstone will be easy to crush but stones made from volcano will be very hard like diamond so will be very difficult
