Jaw Crushers
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

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON CONCRETE STRENGTH AND
to make high-strength concrete, it is easier to do so with coarse aggregates below 12.5 mm (Y, in.) (ACI 363-95). There has not been much research on the effects of coarse aggregate content

Modern Processing Techniques to minimize cost in Cement Industry
Earlier, a typical crushing system used to be a two stage crushing with primary crusher in stage 1 (mostly jaw crusher) and hammer crusher in stage 2. This configuration was typically to suit ball mill applications for grinding. Moreover, the high capacity crushers for size reduction in single stage were not easily available at affordable costs.

uses revolving knives, shredders, crushers, or a combination of these processes. For the grinding, or milling, of the crushed cane, multiple sets of three-roller mills are most commonly used although some mills consist of four, five, or six rollers in multiple sets. Conveyors transport the crushed cane from one mill to the next.

CEMENT and CONCRETE TECHNOLOGY
cement amounts can be reduced because concrete strength is directly related to the water/cement ratio. Definition of Mineral Admixtures Mineral admixtures include fly ash, hydrated lime, silica fume and ground blast furnace slag. Many of these materials have cement-like properties, augmenting the strength and density of the finished concrete.

STRESS-STRAIN CURVE FOR CONCRETE
• The strain at which crushing of concrete takes place is 0.0025 for high-strength concretes to more than 0.0045 for low-strength concretes. • For design, a conservative value of 0.003 is considered as the ultimate strain, for all concretes except very high strength ones.

The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength. The crusher is the workhorse of the hard rock crushing industry.

How Cement Is Made
This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller. The crushed rock is combined with other ingredients such as iron ore or fly ash and ground, mixed, and fed to a cement kiln.

Concrete aggregates properties crushed by jaw and impact secondary
Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.
