The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., ).

Impact Crushers are best used with softer rock, such as limestone and sandstone, and for recycling processed materials like concrete and asphalt. Impact crushers tend to produce more “fines” than Jaw crushers. Jaw Crushers have two opposing ribbed panels, or jaws, with one jaw moving forward and back to crush raw material against the fixed jaw.

Used to crush aggregates, core samples and similar materials when a reduction in sample size is necessary. The crusher has a jaw opening of 100x60 mm and can produce from 100 to 400 kg of material per hour. The movement of the jaws can be adjusted from 2 to 18 mm. The crushed sample can be further reduced using the hammer-mill for laboratory.

Laboratory Jaw crusher is mainly used to broke a variety of ores and bulk materials, it can crush the materials that compressive strength is less than 320Mpa, and it can divided into coarse crushing and fine crushing two broken modes.

Crushers Crushers are an important part of many industrial and materials processing projects. They allow for the crushing of rocks into gravel, smaller rocks, or even miniscule dust. Equipment Trader’s website allows users to quickly search for the best models near to their zip code from the brands and dealers that they have come to trust.

the compressive strength of concrete. Otherwise, the compressive strength of concrete is defined as the maximum crushing stress endured by the concrete. Purpose of this Test. Assume a slab at our site is designed to cast M25 grade of concrete, but we could not define its strength in the semi-solid state.

The word concrete comes from the Latin word "concretus" that means compact or condensed; in fact it is well known that since the second century the Romans mixed quicklime with pozzolan to enhance its hydraulic properties and then mixed it with aggregates in order to obtain a robust stone-like material for the construction of roads and structures.
