Abstract:
A pulverizing system which reduces the size of solid particulate material such as drill cuttings from a wellbore is disclosed. The pulverizing system includes a pair of interconnected cylindrical chambers with each chamber having a rotatable shaft with a plurality of disc sets mounted thereon. The shafts are aligned in parallel relation and operate in a counter rotating manner. Each disc set includes at least one pivotally mounted thrust guide in the form of a bar shaped member. In one embodiment, the thrust guides of the two shafts are arranged in an alternating, interdigitating pattern. The chambers are divided by transverse baffle walls into compartments, with each baffle wall having an opening therein for passage of the particulate material.
