The purpose for taking up this investigation owing to the fact that now a days natural sand confirming to Indian Standards is becoming scarcer and costlier due to its non availability in time because of Law of Land, illegal dredging by sand mafia, accessibility to the river source during rainy season, non confirming with IS 383-1970. Hence the present investigation was taken up with a view to v...

Crushers are machines which use a metal surface to break or compress materials mining operations use crushers, commonly classified by the degree to which they fragment the starting material with primary and secondary crushers handling coarse materials and tertiary and quaternary crushers reducing ore particles to finer gradations. This paper focuses on review of a work carried out by researcher...

Now crushers are one of the most common types crushing equipment using principle a mechanical method material destruction (for example, rollers, jaws, cone crushers, etc.). To provide effective parameters crusher, it is necessary to take into account correlation between physical and characteristics (sizes, shapes, strengths, fragility, uniformity, etc.) energy crusher (operation power) at desig...

operational variables of a mineral processing circuit are subjected to different variations. steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. in thispaper, a dynamic simulator containing some of the major equipment of mineral processing...

A forward predictive model is used to simulate a vehicle's motion given a sequence of commands that could potentially be executed. Generally, forward predictive models are used by planning systems for Unmanned Ground Vehicles (UGV's) so that commands can be selected such that obstacles are avoided. This report presents a data-driven approach for learning a forward predictive model based on prev...

The swimming crab Portunus trituberculatus is a durophagous brachyuran. Right-handed crabs are predominant, but left-handed crabs are also found in nature. Left-handedness may arise from loss of the right crusher. We examined whether heterochely (morphology) was correlated with differences in closing force (physical property) and handedness (behaviour). The closing force was stronger in larger ...
