One object of my invention is to provide --means whereby the material to be crushed may be retarded in its movement through the hopper and temporarily supported in a position to be engaged by the hammers of themtor structure 1n their uprunnlng or overhead movement,<a href="http://www.lightcrusher.com/solutions/sand-making-plant.html">sand making plant</a> and for this purpose I provide a series of grid bars projecting into the hopper space and which may extend part Way or entirely across the path ofthe feed and lying over the rotor structure the hammers of such rotor structure passing between said bars and initially engagingsuch material before it passesto the main crushing zone.
A further object of my invention is to provide the pivotally mounted breaker wall of the hopper with rounded projections carried by a wear-plate member (orme mbers) which may be pivotally mounted in said pivotally mounted wall for cooperative association with and arranged to be projected toward the grid bars,<a href="http://www.lightcrusher.com/solutions/mobile-crusher-for-sale.html">mobile crusher for sale</a> with means for holding said pivotally hung wear plate member (ormemhers) in their adjusted positions.
These and other features of my invention are more fully described hereinafter; reference beinghad to the accompanying drawings, in which: I Figure 1 is a sectional elevation more or less diagrammatic, illustrating a form of hammer crusher mechanism within the scope -housing, indicated generally at 1, which may be made of structural metal and/or heavy cast parts suitably secured together and sup porting the various elements making up the crushingstructure, and more fully referred to hereinafter.
At present, due to the decrease of natural sand, artificial sand will be used as the source construction sand so that it will rank in the building mat...
