By using the data of E.A. Hersam and F.C. Bond's equation for energy consumption in comminution, a method was developed to analyze the performance of industrial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have sufficient …
Gyratory and jaw crushers are always rated at certain open-side or close-side discharge settings. In order that we may select the particular curve, of a group of curves, which will most nearly represent the product of a crusher having any given discharge setting, it is important to know approximately what percentage of the total output will ...

The Jaw Crushers within our range are mobile, tracked, semi-mobile and skid-mounted equipment. They are designed to crush millions of tons of material annually, including: Aggregate; Mine ore; Construction and demolition (C&D) Waste material; Blasted rock and river gravel; Pilot Modular Semi-Mobile Jaw Crushers.
P 80 = size through which 80% of the product passes. This expression was used by Rose and English [11] to calculate the power required for jaw crushers. The expression is claimed to be applicable for gyratory crushers as well. Equation (5.5) indicates that once the comminution parameters, ...
In a jaw crusher, the material is crushed between two plates: a static plate and a moving plate. Compression is applied by the moving plate, and the material …

The specific energy consumption at the motor input can be predicted using Bond's equation: E = 10 × CWi × (P80 – ½ - F80 –½). where CWi is your work index, F80 is the 80% passing size of the feed measured in µm, and P80 is the 80% passing size of the product measured in µm. E is the specific energy in kWh/tonne. Very important -- there are five types of …
