A machine, particularly for producing cellulose fiber from waste paper with characteristics and yield comparable to virgin fiber, includes at least one conveyor body which is adapted to receive the waste material from which to obtain cellulose fiber; and at least one drum which contains inside it grinders adapted to grind the waste material for the production of the cellulose fiber, and which communicates with the conveyor body.

The grinders include a grinding hammer which is arranged on the bottom of the drum and can rotate by way of a motor about a rotation axis.

A cuttings processing unit may include a conveyor interface configured to interface with a mud cleaning complex to receive drill cuttings. The cuttings processing unit may further include a breaker mill module operably positioned to receive the cuttings via the conveyor interface, a cuttings tank module operably positioned beneath the breaker mill module, and a pump module operably positioned beneath the cuttings tank module. The breaker mill module may be configured to grind the cuttings into a finer composition. The cuttings tank module may be configured to agitate the finer composition and create a slurry. The pump module may be configured to move the slurry.

A method of processing organics having a relocatable trailer transporting a hopper, an infeed conveyor, an organics separation unit, an organics conveyor, an inorganics waste conveyor, and a control panel between processing locations of organic material. The control panel regulates the operation of the infeed conveyor, the organics separation unit, the organics conveyor and the inorganics waste conveyor. Following completion of processing the components carried on the trailer may be cleaned and the trailer supporting the processing components may be moved to another processing location.

There is provided an apparatus and method for comminuting a material. The apparatus may comprise a chamber and an inner surface with a plurality of protrusions, and a hammer positioned within said chamber comprising an outer surface having a plurality of second protrusions configured to engage with the first protrusions. The outer and inner surfaces may be separated by a gap distance which defines a comminution zone. The anvil may be rotated to cause a material to be comminuted as the material passes through the comminution zone.

Apparatus and method for recovering precious metals from contaminated cement, comprising, in order of process, a crusher, in which a cement-metal conglomerate is placed, a sieve, a dispenser, a first container, suitable for collecting the metal on the bottom through the action of a magnetic stirrer, an expander, a second container, a drainage tank, and a sieve. The present invention relates in particular to the recovery of precious metal from the batch of cement contaminated by precious metals, such as platinum, rhodium, gold, or silver. In the production of glass fibers for reinforcement, dies made of an alloy of precious metals, in particular platinum and rhodium, are used. These dies are supported by a special cement structure. During the months of production life of the die, part of the precious metal diffuses into the cement on account of the high temperatures. Given the value of the metals, it is economically advantageous to recover them from the supporting cement at each change of the die.

The breaker mill module may be configured to grind the cuttings into a finer composition. The cuttings tank module may be configured to agitate the finer composition and create a slurry. The pump module may be configured to move the slurry.

The present disclosure relates to a cross-flow shredder for grinding material with integrated dust-tight conveying means and air recirculation, and a method for grinding material using the cross-flow shredder according to the disclosure. An apparatus and a method for comminuting material to be ground are disclosed, the apparatus comprising a feed opening for material to be ground, a feed device, a cross-flow shredder, two screw conveyors for conveying the material to be ground and an intermediate dust-tight bunker, the two screw conveyors being connected in a dust-tight manner to the cross-flow shredder on the respective feed side and in a rod-tight manner to the intermediate bunker on the discharge side, the intermediate bunker being connected to the cross-flow shredder via a hose or pipe system, and the intermediate bunker having a discharge opening closed by a slide valve.

A method of processing organics having a relocatable trailer transporting a hopper, an infeed conveyor, an organics separation unit, an organics conveyor, an inorganics waste conveyor, and a control panel between processing locations of organic material. The control panel regulates the operation of the infeed conveyor, the organics separation unit, the organics conveyor and the inorganics waste conveyor. Following completion of processing the components carried on the trailer may be cleaned and the trailer supporting the processing components may be moved to another processing location.
