BRINGING SOUTHERN AFRICAN A TOTAL CRUSHING AND MILLING SOLUTION TERTIARY APPLICATION “PRIMUS” SYSTEM AND ITS ADVANTAGES :-
Innovative winning impact crushing E v o l u t i o n of C r u s h i n g
Maximum particle reduction with one pass
36
A) Impact system allows for producing varied particle sizes by adjusting the rotor speed. Either by changing the pulley or using a variable speed drive. B) Substantial reduction in wear and tear thanks to the innovative impact system. Moreover the wear and tear of the hammers is homogeneous, with a full frontal impact on the hammer as opposed to the tip wear on alternative brand hammer. C) Recirculation of crusher runs are minimal since all material is crushed via a double impact through the flinging action onto the incoming hammer then the subsequent impact on the crusher Different grades obtained wall. from filler to grit. D) Improved shape index of the finished product.. E) Produce uniform fine materials ( - 2mm ) . F) Lower power consumption G) Ideal Pre-Ball Mill crusher.
