Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaw; one is fixed while the other makes an eccentric movement. There are also primary and secondary types of these crushers. Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds ...
· Once the effects of crushed stone dust on concrete properties are obtained, it will be possible to take necessary measures to alleviate its adverse effects on concrete. Experimental Program Materials. In all mixes limestone crushed rock coarse and fine aggregates were used. Dust passing 75 um BS sieve was produced in a laboratory crusher.
· The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.

ENVIRONMENTAL IMPACT OF CONCRETE RECYCLING, COMING FROM CONSTRUCTION AND DEMOLITION WASTE (CDW) Authors: Beatriz Estévez*a, Antonio Aguadoa, Alejandro Josaa a Universitat Politécnica de Catalunya (UPC), School of Civil Engineering (ETSECCPB), Jordi Girona 13, Módulo C1, E08034 Barcelona, Spain
The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure ).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure (a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).
Impact of Concrete Extends to Sand and Gravel Production Nov 1, 2013 Portland cement typically takes the heat for this impact, but as the the most readily quantified environmental impact from aggregate is truck transportation. resident—of construction gravel, crushed stone, and sand in 2012,
aggregates—sand, gravel, crushed stone, and aircooled blastfurnace slag—produce freshly mixed normalweight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 53) are used to produce structural lightweight concrete with a freshly mixed density
· A crushing plant is based in the next main elements: Stone Crushing Plant features. Feeders: These machines feed the jaw and impact crusher with te rocks and stones to be crushed. Jaw Crusher and impact Crusher: These are the machines where the rocks ad stones are crushed.
