The invention relates to the method for milling and separation into fractions of solids and granular materials in a controlled airflow. The device for milling and separation of solids and granular materials consists of a round milling chamber with a system of pneumatic separation comprising of a vertical cylindrical body that has an uploading slot for solids and granular materials and unloading channels for the milled products of light, medium and coarse fractions. A rotating disc and a conical divider are located inside a vertical cylindrical body. The rotating disc has plates (hammers) and removable blades of different sizes and configurations. System of pneumatic separation consists of a milling chamber, an air slugcatcher, channels for the milled material, and a chamber of higher pressure. Such construction of the device allows to obtain products of a highest quality, and to improve the separation by dividing the material into three fractions: light, medium and coarse.

A discharge arrangement (120) for a comminution reactor assembly (100). The discharge arrangement (120) comprises a main chamber (202) extending along a main axis (124). The main chamber has an inlet (121) arranged to be fluidly connected to a comminution reactor (110) and an outlet (122) arranged opposite from the inlet (121) along the main axis (124) and closeable by a common material take-out valve (204). The main chamber (202) is arranged to support a fluid-material stream (123) along a helical path about the main axis (124) from the inlet (121) towards the outlet (122). The discharge arrangement (120) further comprises an airduct (206) arranged extending into the main chamber (202) at an acute angle (a) with respect to the main axis (124). The airduct (206) comprises an aperture arranged facing the outlet (122). Thereby, a portion (125) of the fluid-material stream (123) changes direction from the helical fluid-material stream (123) about the main axis (124) from the inlet (121) towards the outlet (122) to a helical flow inside the airduct (206).

A method of reducing the size of cuttings to fine particles includes obtaining a mixture comprising at least cuttings and drilling fluid and providing a crushing machine including an inlet and a first stage. The first stage includes a first housing, a first rotating hammer with a plurality of blades disposed within the first housing that spins on an axis powered by a motor, a first grate plate, a first water injector coupled to the first housing, and a second stage that is substantially similar to the first stage. The method further includes crushing the cuttings with the first rotating hammer to form reduced-size cuttings and injecting water into the first housing via the first water injector, thereby flowing crushed cuttings through toward the second stage. The method is repeated in the second stage such that the reduced size cuttings become fine particles and flow into a waste pit.

Apparatus (1) for homogenization and separation of substance mixtures composed of particles, having two or more material discharges, wherein a rotating drum (5) is provided, which comminutes and homogenizes the substance mixture, on the one hand, and accelerates the particles in a predetermined direction.

A comminution mill is described that includes a vertically oriented cylindrical housing with an intake chute in a top wall and an outlet chute in a bottom wall thereof. A rotatable shaft with a plurality of radially extending cables is disposed coaxially within the cylindrical housing. A plurality of studs extends inwardly from the wall of the housing to slow and collect materials flowing through the comminution mill. The studs can be withdrawn to discharge materials collected thereon. Slits are provided in the walls of the housing to enable the exit of particulate materials from the housing. A hood is provided overlying the slits on the exterior of the comminution mill for collecting the particulate material. Operation of the comminution mill provides a self-generated airflow and can be configured to separate, grind, and dry materials disposed therein.
