Comminution is an important part of rock disposal in mining and construction. The correct coarse grinding equipment is the key to ensure the efficiency of the crushing line. However, in the crushing process, people are often faced with the dilemma of whether to use a jaw crusher or a rotary crusher.
Working Principle: Jaw crusher utilizes the movement of the upper and lower jaws to crush rocks. They create a squeezing force suitable for crushing large rocks into smaller pieces.
Characteristics: good adaptability to hard and medium-hard rocks; good coarse grinding effect and even particle size; generally simpler to maintain and longer service life.
Scope of application: used for mining, construction, highway and other engineering hard rocks.
Working Principle: Adopting rotary crusher, it utilizes the high-speed rotor to throw the rocks to a fixed piece of percussion disk for impact crushing.
Characteristics: suitable for working in limestone, shale and other soft rocks; suitable for the impulse crushing method of grinding stones into large grains; the high-speed turning rotor can produce great impact energy.
Scope of application: suitable for cement, building materials, chemical products, especially for soft materials.
First of all, it is important to know which kind of rock is to be dealt with. Hard rocks are usually used for jaw crushing, while those used for rotary crushing are used for crushing. According to the production requirements, decide the size and capacity of the equipment needed. Jaw crushers are generally used for large scale capacity requirements while rotary crushers are more suitable for small scale projects. Consider the budget as the prices of various equipment are different. The maintenance requirements and cost of the equipment should be thoroughly analyzed to ensure the viability of its long-term operation.
