After the natural materials are gathered, the aggregate is processed, screened and washed to remove any unwanted coatings or chemicals. When processing, aggregates are fed through a primary crusher which will reduce the size of the concrete into chunks. After inspection for large usable products, the remaining materials from the …
Demystifying Aggregate Crushers This overview aims to provide clarity on the diverse array of crushers available and guide the appropriate match for various aggregate projects. Deciphering...
The high cost of labor keeps going up. A stationary crusher might be able to produce multiple times the amount of product, but also would require about seven or eight workers. Aggregate producers can benefit when producing material with the minimized crew used for mobile jaw and impact crushers. MOBILE CRUSHER MAINTENANCE

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a …
Impact crushers. An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor. Secondary breakage then occurs as the material is accelerated into the stationary aprons or breaker plates.
Large rocks (often limestone) are processed in a stone crusher to make smaller pieces. Since it is artificially crushed, crushed stone usually has harder, sharper edges than gravel. ... or as an aggregate in concrete. …

At their simplest, rock screens are made up of a screen box, a specific amount of screen decks, screen media and a vibrating mechanism that shakes and moves rocks through the screens. ... Aggregate producers will know what openings to put on each deck to make the specific products needed. For example, if a …
Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
