bond impact crushing work index testing machine - pendulum. Crusher productivity in quantities of a fixed size distribution is a function of power drawn as opposed to physical machine size. From the results of the pendulum tests, it is possible to visualize a small machine drawing more power outproducing a larger machine drawing less power.

intention of decreasing the Bond work index (Wi) will produce large energy savings (Workman and Eloranta 2003). In the previous research the specific crushing energy was determined indirectly based on the pendulum or falling weight tests. None of these ways of testing simulates the motion of the jaw crushers jaw.
apparatus consists of two pendulum hammers mounted on two bicycle wheels, so as to strike equal blows simultaneously on opposite sides of each rock specimen. The height of the pendulum is raised until the energy is sufficient to break the specimen 7. The crusher work index (cWI) or impact work index is calculated as follows
In spite of such longstanding use, the topic of accuracy and precision of Bond work index determinations recurs with great frequency (Mosher and Tague, 2001). Single particle tests to determine the comminution behavior of ore and coal can be separated into a twin pendulum device (Figure 1) and drop weight apparatus-based tests (Figure 2).
GRINDABILITY TESTS Bond Rod mill work Index The rod mill work Index is also normally distributed with and average and median of 14.8kWh/t It is common to observe difference between the ball and rod mill caused by variation in ore hardness The test has been mainly used for the design of rod mill or primary ball mills. http ...

The Rosin- Rammler distribution has also been found inadequate to generally describe crusher products. Work during the early 60s led to the concept of comminution as a repetitive process, with each step consisting of two basic operations the selection of a particle for breakage and the subsequent breakage of this particle by the machine.

Jan 01, 2016 The energy for crushing, E, is the difference between the energy of the input pendulum and the energy of the rebound pendulum and is computed from the following expression (3.19) E E S 1 2 M B M B M S Units energy terms ( E ) kWh/t 3600 kJ/t. mass kg. the value of 00.2.
Dec 01, 2007 The Bond crushing work index is a measure of material strength and is determined using a simple twin pendulum apparatus and a standard procedure. The Bond impact test attempts to emulate the crushing action that occurs inside the chamber of jaw, cone and gyratory crushers, where particles may not be broken in the first nipping cycle, but only ...
Mar 10, 2020 The F. Bond Pendulum crusher Carring on with a theme that weve already touched in the previous publication, we will consider the methodology of the F. Bond index calculating. As you know, there are three calculation methods. The method selection depends on the crushing/grinding stage (the power size and the necessary finished class). The crushing

The height of the pendulum is raised until the energy is sufficient to break the rock specimen. ... Power limit is reached when average power draw kW exceeds the installed motor power of the crusher. Ore of high impact work index or strong resistance to fragmentation tend to reach or exceed the power limit easily.
power index with the double pendulum impact testing machine, impact crushing work index determination of ore or materials, and hard to the index size that can be broken. The efficiency of the crusher is usually used than power, crushing one ton of ore size of the power (kW ? h).
After the first single particle breakage test, the Bond Crusher Work Index Test reported in 1947 9, several single particle breakage tests were developed, such as
Although not as popular as the Bond ball mill or the Bond rod mill work indices, the impact work index, also called Bond crushability index, continues to be much used for crusher selection.

Jul 06, 2014 I bought the Rock Crusher Studio as it did everything the Torpedo Live did AND it had a spectacular attenuator. While its very good as an attenuator, it just doesnt have the liveliness that the Torpedo Live has. Some of the notes seem to fall flat on the Rockcrusher. With the Torpedo Live the notes have sustain and a lively chime to them.
