Изобретение относитс к области обработки материалов давлением.This invention relates to the field of pressure treatment of materials.
Известный валковый пресс дл уплотнени тонкодисперсных порошков содержит встречно-вращаемые полые валки, разделенные на секторы, сообщаемые с системами разрежени и нагнетани , и охватывающий валки фильтрующий элемент дл отделени валка от уплотн емого материала.A known roller press for compacting fine powders contains anti-rotating hollow rolls divided into sectors communicated with a vacuum and pressurization system, and a filtering element enclosing the rolls for separating the roll from the material to be densified.
Недостатком таких прессов вл етс быстрый износ фильтрующей ткани (стойкость ее исчисл етс мес цами) и практическа невозможность их использовани при работе на давлени х пор дка 500 кг/см и выше из-за износа фильтрующей ткани.The disadvantage of such presses is the rapid wear of the filter cloth (its durability is calculated in months) and the practical impossibility of their use when working at pressures of the order of 500 kg / cm and higher due to the wear of the filter cloth.
С целью повыщени износостойкости фильтрующего элемента и степени уплотнени материала в предлагаемом прессе кольцевойIn order to increase the wear resistance of the filter element and the degree of compaction of the material in the proposed press ring
фильтрующий элемент выполнен из пористого металлокерамического материала и закреплен на валке.The filter element is made of porous cermet material and mounted on a roll.
