Abstract

PROCESSO E EQUIPAMENTO PARA SELEçãO DE LASCAS Processo e equipamento para seleção de lascas (3). As lascas, que têm energia cinética, são separadas umas das outras com base na forma ou no tamanho de sua curva de vóo, que depende da respectiva resistência ao ar. A energia cinética das lascas é gerada por um dispositivo mecânico de ejeção (6), que ejeta as lascas, ou por meio de um transportador de ventoinha ou por meio de pás de um lasqueador de sopro.
