A tie wrap connector is formed of a strap, a locking head and an insert positioned adjacent said locking head. The cut-out or opening is defined by a headwear bottom side edge that is substantially different andor higher than the generally smooth, consistent arc seen in the prior art. The crushed products are carried in the air flow, which is generated around a guide vane disc, which rotates in a through hole formed in a substantially central portion of the stationary plate, and forcibly delivered from an exit in the housing side wall front portion inclined forward, to the outside of the housing.
