Title (EN) CUTTING DRUM FOR BORER MINER
(FR) TAMBOUR DE COUPE POUR MINEUR DE TYPE FOREUSE
Abstract:
(EN) A cutting drum for a borer-type continuous miner and in particular, although not exclusively, to a bottom cutting drum mountable immediately behind forwardmost primary cutting rotors. The cutting drum comprises a plurality of material transport blades extending lengthwise along the drum between the pick holders and positioned side-by-side in a circumferential direction around the drum to cover an outward facing drum face. The blades are effective to provide transport of cut material to minimise power consumption of the cutting head and accelerated wear of cutting picks.
(FR) L'invention concerne un tambour de coupe pour un mineur continu de type foreuse et, en particulier mais pas exclusivement, un tambour de coupe inférieur pouvant être monté immédiatement derrière les rotors de coupe primaires les plus en avant. Le tambour de coupe comprend une pluralité de lames de transport de matériau s'étendant dans le sens de la longueur le long du tambour entre les supports de pics et disposées côte à côte dans le sens de la circonférence autour du tambour afin de couvrir une face de tambour tournée vers l'extérieur. Les lames sont efficaces pour transporter le matériau coupé en réduisant au minimum la consommation d'énergie de la tête de coupe ainsi que l'usure accélérée des pics de coupe.
