What is the difference between crushing and grinding?
Sep 07, 2020However, there are lots differences between crushing and grinding, and each progress need different machines. The progress of processing large stones or rocks into smaller size (mainly granularity size) is called crushing. The final granularity size mainly varies from 1 mm to 50 mm. A stone crusher machine is needed when crushing something.

Crushing Vs Grinding Minerallurgy
Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction.

Understanding comminution: Compression versus impact
Aug 18, 2020Mining equipment creates impacts by using a rotor to violently hit and throw rock against the walls of a crushing chamber. As a kind of basic first rule you could say: Impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%).

Understanding Comminution: Compression versus impact
As a basic rule, impact crushing is suitable for rocks with a low work index (<12) as well as low silica (<20%) and moisture levels (<5%). Rocks with these characteristics are soft and non-abrasive, and easily broken within the crushing chamber, keeping wear rates at a minimum, and producing high reduction ratios with a better-shaped end product.

Milling vs. Grinding obsidianmfg
Sep 17, 2019Milling says : Avoid interrupted cuts. An interrupted cut is one where the tool alternately enters and leaves the workpiece during the cut. Because cast iron has relatively low tensile strength, the tendency of the cutting forces it to break out the edge of the casting as the tool leaves the work.

As the grinding mill vibrates, media particle migration is experienced in both axial and transverse directions. In fact, the media migrates through the VIBRA-DRUM® Grinding Mill in a path similar to that of a rotary grinding mill without lifters, but each media particle imparts positive impact energy at each vibration.

Milling process services from Custom Processing Services
The shearing forces (tearing apart), impacting (crushing by outside forces), and attrition (tearing and crushing each other apart) create particle distributions in the nanometer or sub-micron ranges. The media in autogenous grinding can be large pieces of material, so this technique is milling by attrition (self-grinding), not by impact.
