Abstract

SISTEMA DE CONTROLE DE EFICIêNCIA DE SEPARAçãO EM PENEIRAS VIBRATóRIAS do tipo que compreende um elemento de peneira (10), na qual é mancalizado um eixo (20 carregando pelo menos um peso excêntrico 30) e acionado Rotativamente por um motor elétrico (60). O sistema compreende um sensor de carga (LS) para produzir um sinal representativo da carga de material a granel sendo alimentada ao elemento de peneira (10); um conversor de freqüência (70); e uma unidade de processamento (80), associada ao sensor de carga (LS) e ao conversor de freqüência (70), de modo a instruir uma velocidade de giro do motor elétrico (60), do eixo (20) e do peso excêntrico (30) e uma conseqüente velocidade de transporte do material a granel sobre o elemento de peneira (10) , necessária para manter a espessura da carga de material a granel e o tempo de sua permanência sobre o elemento de peneira (10) dentro de valores predeterminados.VIBRATING SCREEN SEPARATION EFFICIENCY CONTROL SYSTEM of the type comprising a sieve element (10), on which a shaft (20 carrying at least one eccentric weight 30) is rotatably driven by an electric motor (60). The system comprises a load sensor (LS) for producing a signal representative of the bulk material load being fed to the screen element (10); a frequency converter (70); and a processing unit (80) associated with the load sensor (LS) and the frequency converter (70) to instruct a rotational speed of the electric motor (60), the shaft (20) and the eccentric weight (30) and a consequent transport speed of bulk material over the sieve member (10), necessary to keep the bulk material charge thickness and the time of its permanence over the sieve member (10) within predetermined.
