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.
Claims11
A pulverizing system for producing finely ground material, comprising:
- a tank member formed by a pair of interconnected cylindrical chambers which are in fluid communication and in overlapping relation along the length thereof, said tank having first and second ends, wherein said first end has an inlet for receiving feed material and said second end has a material discharge opening;
- a pair of shafts with one shaft being rotatably mounted in each cylindrical chamber;
- means for rotating said shafts;
- a plurality of disc members mounted on each shaft, at least one of said disc members on each shaft having at least one thrust guide member in the form of an elongated bar or rod pivotally mounted thereon, wherein each of said chambers has substantially smooth, longitudinally extending interior wall surfaces adjacent said at least one thrust guide member of the respective shaft throughout substantially the arc of rotation of said at least one thrust guide member.

- a pair of shafts with one shaft being rotatably mounted coaxially in each cylindrical chamber, said shafts extending in parallel relation throughout the length of the chambers;
- means for rotating said shafts;
- a plurality of disc members mounted on each shaft in position generally transverse to the longitudinal axis of the chambers;
- and
- at least one thrust guide member in the form of an elongated bar or rod pivotally mounted on each disc member, wherein each of said chambers has substantially smooth, longitudinally extending interior wall surfaces adjacent at least one thrust guide member throughout substantially the arc of rotation of said at least one thrust guide member of each of said chambers.
