A personal blog about crushing equipment
Kamol Mirzaev on stone, crushers, and decisions that hold up in the real world.
I started learning about crushers when I had to choose equipment myself. Now I record what I would have wanted to know at the beginning.

Do not stop at the data sheet — understand the conditions behind it.
Capacity never comes from a single row in a table. Rock, moisture, feed size, target fraction, wear, and the entire line all matter. This blog explains how those factors connect.

How one impact crusher turned a list of questions into Kamneblog.uz.
Kamol began by comparing models. Then he learned that a sound choice starts with the material and the required product, not a model name.

An impact crusher, without catalogue language.
An impact crusher breaks material with a fast rotor and impact surfaces inside its housing. Its position in a line depends on the feed, target product, and process design. Adjusting working gaps can influence output size, but selection always starts with reliable material data.
Important: jaws and feed-opening dimensions belong to jaw crushers. Impact crushers use a different breaking principle.
