Static-stress ball press machine (low-strain ball press machine is appropriate to be applied to industrial gasoline era, boiler coal, cold-stress coal briquettes, family coal briquettes, household metallurgy, refractories and medicines and etc. Briefly, the machine is driven by a synchronous servo motor, and the facility is transfered to the slide plate by a pair of screw nut, and finally punch the refractory or the recent steel by the mildew. Then, the refractory combination powders were placed inside a metal mold and mixed with an organic binder (ethylene glycol at 2 wt. %) to be uniaxially pressed (UP) at one hundred MPa for two min, so 4 batches of samples had been compacted.
The hydraulic press for refractory bricks products are most popular in India, Pakistan, Vietnam, Indonesia, Brazil, Russia, Mexico, United States, Turkey, Germany, and so forth. A mathematical model of the CM1085 electromechanical press system has been developed, which describes the dynamic processes in the electric drive with varying technological parameters and management system parameters, which differs from the identified ones bearing in mind the influence of changes within the supply voltage, moisture content of the refractory mass, and also taking into consideration the specificity of the knee-lever mechanism on the standard of uncooked molding. 9.
