INTRODUCTION TO IMPACT LOADING
Although the impact force varies with time, an average or effective force Feff can be assumed which acts over the impact duration, ∆t, such that Feff∆t = ⌡⌠ ∆t Fdt . Using physical reasoning to estimate the interval, ∆t, then Feff = m∆V ∆t. will provide a reasonable estimate of the impact force.

The difficulties with the first method include inaccurate stiffness coefficients [4] and simple models for the impact force and the crush energy. As a result, large errors in the estimation of the vehicles' speeds are expected. To improve

Prediction Model of Drilling Performance for Percussive ...
In tophammer drilling, the impact force is supplied by a hydraulic drifter. In DTH drilling, the impact force comes from a hammer system operated by compressed air. Tophammer drilling is mainly used for boring lengths of 1–20 m (, during blasting in mining and civil engineering), although it can be used up to 40 m. Meanwhile, DTH drilling is frequently used for groundwater development ...

Rock Crushing Rule of Thumb
· Impact crushers (rotary or hammer mills) have the capacity for high reduction ratios (up to 40:1), but are rarely applied to hard rock mines. Since they depend on high velocities for crushing, wear is greater than for jaw or gyratory crushers. Hence, they should not be used in hard rock mines that normally have ores containing more than 15% silica (or any ores that are abrasive). Source: Barry ...
