Sand & gravel plant crusher
The stone crusher is a commonly used stone crushing equipment in the sand and gravel industry. It can crush stones such as granite and limestone into construction sand & gravel. It is widely applied in construction, railways, highways, water conservancy and other industries. There are many types and models of stone crushers, and different models have different output with different cost. There are mainly the following types
(1) Jaw Crusher; Production capacity: 1-1500tons/hour
When encountering large raw materials, it is necessary to use jaw crusher. The largest equipment has a large feeding port and can be crushed into particles below 300mm through materials with a feeding size below 1200mm. The crushing capacity is strong, and it can provide suitable grain size for the next crushing link. Using the dynamic and static jaw plates to bite, squeeze and crush the materials, and can crush stones of various hardness. It is also a special crusher for coarse crushing in the stone crushing production line.
(2) Impact crusher/cone crusher; Production capacity: 20-1500 tons/hour
The cone crusher is mainly used for the secondary crushing of materials, suitable for rocks with medium hardness and above, and the crushing ratio of ores is large; it has a multi-cavity crushing method, and the crushing cavity can be replaced according to the requirements of the finished product to complete the finished product requirements; and it has a cavity-clearing hydraulic protection system device , When the unbreakable foreign object is broken, it can automatically stop to ensure the safety of human and machine;
The impact crusher can be used for secondary and tertiary crushing, and is more suitable for the crushing of soft materials. It mainly relies on the rotor and the impact plate to crush the stone falling into the crushing cavity through the rotor and the impact plate. The stone is finely crushed, the sand and gravel crushing effect is good, and the particle size of the finished product is uniform.
