HAZEMAG sells wobbler feeder and roll crusher to Estonia
VKG Kaevandused OÜ ordered a wobbler feeder (Fig. 1) and a roll crusher (Fig. 2) for processing oil shale in Ojamaa Mine in Estonia. The machines have just passed the acceptance test in HAZEMAG’s production in Dülmen. The wobbler feeder, which is connected upstream of the roll crusher, screens the fines from the feed material (approx. 1000 t/h). The coarse material, approx. 250 t/h, is crushed by the roll crusher to reach the desired particle size of 0-125 mm. By using the wobbler feeder as a primary screen, a smaller type of crusher can be used for the subsequent crushing. The gap of the roll crusher can be infinitely varied using a hydraulic system. In case a contaminant enters the machine, the movably supported roll moves aside hydraulically, lets the contaminant pass and moves back into its preset position. In subsequent process steps, the resulting product is used as fuel or for oil extraction.
