Side Setting (CSS) and Eccentric Throw (ECC) on crushers and separation size on screens. Simulation of crushing plants is often performed with steady state simulation. There are two main reasons for using steady state simulation: It utilises a limited amount of CPU power and it gives a prediction of the long term performance of the plant.

Power efficient As well as being fitted with the latest in high-efficiency motors, HP new generation crushers enable a higher output of finished product than any other cone crusher with the same power input. The result is improved overall efficiency (less power consumed, more yield), and as a bonus, less carbon dioxide emission, making
In the event of a segregation that acts as a feeding miss-alignment, due to a wider PSD on one side of the crusher increasing power draw locally, the method of moving the feed can be implemented. These solutions are fairly well known but the key to solving the issues is to find the segregation problem and to pinpoint the characteristics …
Some key structural parameters like bottom angle of mantle, eccentric angle, length of parallel zone have also put major impact on the crushed material quality …

Differentiate between work and power. State the condition when a force produces (i) linear motion. (ii) rotational motion, in a body. What do you mean by equilibrium of a body
• Power limit: Power consumption will vary based on the crushing chamber used and the eccentric throw: increased throw = increased power draw. The power limit is exceeded if the crusher drive motor draws more power than it is rated for (the attached power must be compatible with the actual throw being used in the crusher). 5.
Here is a list of Rules of Thumb often used in Rock Crushing and around Crushers: Crusher Selection For a hard rock mine application below 600 tonnes/hour, select a jaw as the primary crusher. Over 1,000 tph, select a gyratory crusher. Between these capacities, you have a choice. Source: Chris Ottergren For a hard rock mine …
Impact Crushers. An impact crusher (also called a hammer crusher) is quite versatile. It can be used as a primary, secondary, or tertiary crusher. Impact plates and beaters – or hammers – are used to break down the material. The material is fed through the upper part of the crusher then hit by hammers.
A power draw of 75 to 95 percent is a great target range to stay within while crushing. Excessive power peaks, particularly above 110 percent rated horsepower, should be avoided as this could lead to premature crusher failure. ... A slowing crusher will cause incredibly high power peaks at a very low crusher throughput tonnage. Improper or ...

The maximum power indicated on the name-plate is the power on the output shaft of the motor (or mill shell for gearless). The maximum power indicated can only be evolved at the rated speed indicated on the name-plate. Below the rated speed, the motor's available power reduces linearly as a function of actual speed over rated speed.
