Crusher, crusher, and shredder are three common types of mechanical equipment, what is the difference between them? Let’s make a distinction below.
The pulverizer is a kind of equipment that processes materials into powder, which can be divided into self-propelled jaw mills and hydraulic jaw mills according to the hardness of the materials. It can process materials into inorganic powders below 20 mesh, and the biggest feature is that the resulting material powder has a high fineness.
Crusher refers to mechanical equipment that cuts or crushes large pieces of material to the required size, which can be divided into two types: jaw crusher and impact crusher. They can process materials into more uniform crushing, and the biggest feature is that they can quickly crush large pieces of material to the required size.

Shredders are specialized equipment for shredding waste items, which can quickly process waste such as scrap iron, scrap steel, paper, and wood into materials that are easy to transport, store, and reuse. Its biggest feature is that it can effectively treat various types of waste, which is of great significance to waste classification and resource utilization.
To sum up, the pulverizer is mainly used for the particles to fall to the required size, while the crusher is mainly used to crush large materials into the required size, and the shredder is mainly a machine for processing waste materials.
So, how to choose these mechanical equipment? Different equipment is selected according to the needs of different industries to meet the needs of production and processing. If it is used for the production of flour, fruits and vegetables, chemicals, etc., you can choose a crusher, if you need to convert biomass into oil, you can choose a crusher, and for the treatment of garbage waste, you can choose a shredder.

Great breakdown! Now I finally understand the difference between these machines. 👍
This is super helpful for my construction business. Gonna share it with my team!
Wait so if I need to process wood waste, I should get a shredder not a crusher? 🤔
The part about fineness in pulverizers was really interesting. Never knew they could get that precise.
lol my brain was crushing trying to understand this before reading. Thanks for making it simple!
Anyone know where to buy affordable shredders for home use? Got too much cardboard piling up.
The biomass to oil conversion part blew my mind. Technology is crazy these days.
Wish there were more pictures though. Visuals would help understand the mechanisms better.
As a mechanic, I can confirm this info is spot on. Good job explaining technical stuff simply.
So basically: powder = pulverizer, chunks = crusher, trash = shredder. Got it! 😄
The waste classification benefits are huge. More people need to read this!
Kinda surprised there’s no mention of safety precautions when operating these machines.
This makes me appreciate how much engineering goes into simple-looking industrial equipment.
Would love to see a follow-up comparing brands and models. The market is overwhelming!
My uncle works at a recycling plant and says shredders are the most fun to operate. Wonder why?
