Knowledge points for four different types of crushers

The so-called crusher is the function of crushing certain substances. Depending on the usage and performance requirements in different fields, the crushers we may use may vary. There are four common types of crushers: jaw crushers, cone crushers, roller crushers, and impact crushers. The knowledge analysis of these four different types of crushers is as follows.

1. A jaw crusher (tiger mouth). The crushing effect is achieved by periodically pressing the movable jaw towards the fixed jaw, crushing the ore blocks sandwiched within it.

2. Cone crusher. The ore block is located between the inner and outer cones, with the outer cone fixed and the inner cone swinging eccentrically to crush or break the ore block sandwiched between them.

3. Roller crusher. The ore block is mainly subjected to continuous crushing in the gap between two opposite rotating circular rollers, but also has grinding and stripping effects. The toothed roller surface also has splitting effects. Belt conveyor,

4. Impact crusher. The ore block is shattered by the impact of rapidly rotating moving components. Belonging to this category can be further divided into: hammer crusher; Cage crusher; Impact crusher.

What are shaft sleeves and bearing sleeves

The bearing shell is equivalent to the outer ring of a sliding bearing. The bearing sleeve is integral and moves relative to the shaft, while some of the bearing shells are segmented and rotate relative to the shaft.

Journal: The part of a shaft that is supported by bearings;

Bearing bush: a part that matches the journal;

Shaft sleeve: A sleeve made into a whole cylindrical shape.

Bearing sleeve: Bearing inner sleeve, also known as bearing sleeve, sleeve, cylindrical structure CNC precision grinding sleeve.
