Fig 1 Methods for size reduction of materials The reduction of size of the material when it pass through a crusher is expressed as reduction ratio. The reduction ratio is the ratio of the crusher feed size to product size. The sizes are usually defined as the 80 % passing size of the cumulative size distribution. Types of crushers

Jaw crushers are generally considered a primary or first-stage crusher. The maximum feed size can be as large as 80–85% of the crusher's gape or depth, while reduction ratios range from 2–3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher has begun the reduction process earlier in the circuit.

43.1 Introduction. Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, i.e. compression, impact and shear.

Impact: Impact-based size reduction involves subjecting the material to high-speed collisions with the help of stationary or rotating objects.Impact mills, hammer mills, and impact crushers are commonly used for this purpose. Attrition: Attrition occurs when particles are rubbed or sheared against each other, resulting in size reduction.Attrition …

For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps to ultra-fine powders, are normally attained by several stages using diverse crushing and grinding machines. ...

Size reduction. Zeki Berk, in Food Process Engineering and Technology, 2009. 6.3.3 Energy consumption. As a rule, size reduction operations are heavy in energy consumption (Loncin and Merson, 1979; Hassanpour et al., 2004).As an example, the cost of energy is the single largest item in the total cost of wheat milling. Milling of one bushel (approx. 27 …

Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...

Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with the feed. The initial impact is responsible for more than 60% of the crushing action, with the remainder being made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.
