New concept eccentric crusher

The new eccentric roll crusher implements an entirely new concept in primary crushing of hard rock.

Thyssenkrupp’s eccentric roll crusher (ERC), with its patented combination of pre-screening and crushing, uniquely combines compact design and the ability to crush hard rock with high throughputs in an energy efficient manner.

Installation height has been reduced by between 20 and 50 per cent, compared to similar performing gyratory or jaw crusher options, which also makes it an overall lighter package.

A prototype of the machine was built and extensively field-tested in a six-month campaign at a hard rock quarry in Germany. The crusher model ERC 25-25 selected for this purpose has a crushing roll of 2500mm in diameter and width. The feed opening into the crushing chamber is 2500mm wide and 1230mm high.

During this pilot operation, average capacities of 2000 to 3000 tonnes per hour (tph) were recorded. The desired product size of 0-200 (x) mm was achieved at various settings, with P80 at CSS of 140mm recorded with approximately 130mm. The integrated grizzly effectively bypassed fines and contributed around 30 to 40 per cent to the total equipment capacity.

The first ERC for commercial operation has already been sold and it will be on show at bauma 2019.
