Description

An adjustable buffer power adjustment mechanism for a hammer crusher

technical field

The invention relates to the field of mechanical equipment, in particular to an adjustable buffer power adjustment mechanism for a hammer crusher.

Background technique

Crusher, also called stone crusher, can be divided into medical stone crusher and mining stone crusher according to major categories.

The crushing ratio is large, and the crushed material is in the form of cubic particles. Mining crushing machinery refers to the crushing machinery in which the particle size greater than 3 mm in the discharge accounts for more than 50% of the total discharge. The hammer crusher is a crusher for crushing materials with a maximum particle size of 600-1800 mm to 25 mm or less. The hammer crusher is suitable for crushing medium-hard materials in industrial sectors such as cement, chemical industry, electric power, and metallurgy, such as secondary and fine crushing of limestone, slag, coke, coal and other materials.
