Crushing and srceening loading machine DSPM-1250

 

Crushing and screening loading machine DSPM-1250 is designed for crushing, classification and loading of coal into transport vehicles in open-cut mines and coal storage yards with coal enrichment by “dry method”.

 

Machine includes screw screens 1 and 2, screw crushing and screening plant 3, elevating conveyer 4, conveyer for screenings 5, stockpile conveyors 6, 7.

 

Machine DSPM-1250 works in the following way: coal is fed by bucket wheel excavator onto the screw screen 1 where it is separated into two fractions. Undersize is loaded into railway cars via conveyor systems 5 and 7. Oversize fraction passes via conveyor 4 into crusher 3 and further to the screw screen 2. Undersize from the screen 2 is loaded onto conveyor 5, and further via conveyor 7 into railway cars. Oversize passes onto conveyor 6 and is transported to the coal storage yard. The upper section of the crusher can be replaced by a section of special design. In this case the crusher operates as screw sorting machine (see description on page 6) and is able to enrich coal by “dry method”.

 

Capacity of crushing and screening loading machine is 1250 t/h; weight – 150 t.
