The Briquette Testing Press is an automatic equipment that performs the compressive strength test on iron ore briquettes. The briquettes are initially positioned on the test disk placed in each slot individually, where the rotation of the disk positions the briquettes to the test site, where compression occurs until rupture.

 

The number of briquettes to be tested is pre-set by the operator, and the excess is discarded after the end of the test. At the end of the test, the results will be presented with measured values for each individual briquette, as well as general statistics. A report will also be generated, which can be printed or saved electronically by the operator. The test follows all the procedures established by the ISO 4700:2007 standard.

 

The main advantages of the Briquette Testing Press are its greater precision in the application of the load, positioning of the briquette to be pressed and the generation of automatic reports, besides dispensing with routine adjustments in order to maintain the load application within the standard required by the norm. Most presses found in the market use a hydraulic unit for load application. The fluid flow control valves of this system wear out, and routine adjustments are needed in order to try to maintain the load application condition at a constant speed.

 

The robotic press comes to solve this problem by changing the load application system to an electromechanical servo controlled system. Besides guaranteeing a load application at constant speed, the positioning system of the briquette to be pressed is done by an automated disk with no intermediate stop, thus increasing the precision of the stopping point in the pressing position, and decreasing the test time.
