New Hercules static Trommel in Norway.

The model HT212 was chosen due to its heavy duty features when working with a very abrasive feed material and for processing large product sizes at high rates. The HT212 is rated up to 750 tph and can accept a maximum lump size of 1050mm direct from a dump truck into the heavy duty feed hopper.


The customer requires specific weights of rocks to be screened from the trommel barrel and this required the barrel to be designed specifically to suit these parameters while maximising the ‘open area’ of the screening surface. Chutes are fitted under the second half of the 8m-long barrel for separating the different product sizes ready for collection from bays on each side of the trommel.


It would not have been possible to carry out this project with any other screening method than the trommel based on the large feed size, high tonnage rates required and large product sizes required.


The modular design of the trommel allows for simple installation and allows the trommel to be running very quickly after delivery to site from the company’s own factory based in the UK.
