Which crushing device has the highest efficiency?
Jul 12, 2016 · It is seen that for a reduction ratio of 1.32, the relative efficiency of crushing a multi-layer of particles is 72%. Note that crushing ratios in a ball mill are not well defined, but are believed to range up to 1.5 or even 2.0. In a second series of measurements, the particle size was not uniform—a distribution of particle sizes ...

Jaw crushers are routinely choke fed, as this maximizes production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing, breaking up flaky or slabby particles. If you seek fewer fines, trickle feeding material into the jaw crusher could achieve this. But this would have an adverse effect on particle shape, and ...
Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent. The finer the closed-side setting, th...
Uniform distribution of feed material around the cone crusher inlet is good practice. This allows production of a consistent product, as well as efficient, reliable operation of the crusher. Choke feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter-particle crushing action. Trickle feeding is n...
The liner profiles are designed for a range of product sizes, from extra coarse to extra fine. The extra fine liner profile will result in the highest fines proportion for a given cone crusher. It’s important to find the right liner for the feed gradation and desired product. If the liner is too large, feed material will drop too far in the chamber...
Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 percent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle collision. This is why it is vi...
Size reduction and, ultimately, the crusher setting are directly proportional to the rotor speed. This largely dictates how many fines are produced. Slower rotor speeds can be used as a means of reducing fines but may result in a product with more oversize or return than is desired. Slower rotor speeds are preferable as a means of minimizing the we...
Follow the steps outlined in this article to achieve the best crushing efficiency for jaw, cone, gyratory and impact crushers and to ultimately increase profits and reduce fines production. By taking these steps, you’re reducing the amount fines produced and adding dollars to your pocket. Information for this article courtesy of McLanahan Corp.
Crush Force Efficiency and Specific Energy Absorption explained. What are they and why are they important?
Crushing efficiency is essentially the ratio of the amount of raw material entering a crusher to the amount of product that exits the crusher after processing. The higher the efficiency, the less energy and time needed to convert the input into the desired output. The Importance of Crushing Efficiency.

Apr 1, 2019 · Efficiency can be defined by the ratio of work done by a machine to the energy supplied to it. To apply what this means to your crusher, in your reduction process you are producing exactly the sizes your market is demanding. In the past, quarries produced a range of single-size aggregate products up to 40mm in size.
