A rotor 10 of a centrifuge 100, having a receiving chamber 18 for samples to be centrifuged, a concentrically mounted seat 20 which is associated with a support 106 of a drive shaft 104 of said centrifuge 100, a lid 40 which limits the receiving chamber 18 at the top, which is mounted concentrically relative to the rotor and which has, on its side remote from the receiving chamber 18, a handle 44 for carrying the rotor and the lid 40, and a locking mechanism 50, 34b of lid 40 and rotor, which locking mechanism 50, 34b comprises a locking element 50 which can be moved between a locking position and an unlocking position thereof. In accordance with the invention, part of the handle 44 is adapted to be movable and is operatively connected to a retaining element 48b, 48c, which retaining element 48b, 48c can be moved, by the handle 44, between a first position which prevents actuation of the locking element 50, and a second position which releases the locking element 50.

A centrifuge having a housing containing a rotational mechanism and a centrifugal container having a longitudinal axis. The rotational mechanism has a circuit including an electrical motor, a switch, and an internal electrical power source. The centrifugal container is operably connected to the rotational mechanism through the housing, and is rotatable about the longitudinal axis. The centrifuge is portable and is for single use.

A method and system for separating a suspension into solid and fluid components. The suspension is centrifuged about a substantially vertical axis of rotation to concentrate solid components in a first lower flow stream and fluid components in a first upper flow stream. The first upper flow stream may be centrifuged about a substantially vertical axis of rotation to concentrate solid components in a second lower flow stream and fluid components in a second upper flow stream. The first lower flow stream, the second lower flow stream, or both, may be centrifuged about a substantially horizontal axis of rotation to separate water from stackable dry tailings. The method and system may be applied to separation of tailings or other suspensions.

A modular centrifuge device for separating fluid samples, including a housing having a modular power assembly mechanism for rotating samples with manual or electric power. A manual centrifuge device, including a housing having a power assembly mechanism for rotating samples with manual power, and a speed indicator for indicating if a predetermined speed has been reached and a time indicator for indicating if a predetermined or calculated time has been reached for rotating said samples operatively connected to the device. A method of centrifuging samples, by selecting a manual power mode or electric power mode on a centrifuge, rotating samples at a predetermined speed for a predetermined or calculated time, alerting a user that the predetermined speed and predetermined or calculated time have been achieved, and obtaining separated samples.

An attachment fitting is attached inside a rotor hole. The attachment fitting is made up of a main body, first and second pieces disposed in a piece placement hole formed in the main body so as to pass therethrough in a direction orthogonal to a rotation central axis of a rotor, a leaf spring including two arm portions, and a retainer that is mounted on the main body and puts a base of the leaf spring between the retainer and the main body. The first and second pieces have grooves into which the arm portions of the leaf spring are inserted. When the rotor rotates, the first and second pieces protrude from the piece placement hole by the centrifugal force against the spring force of the leaf spring and make contact with a rotor coupling portion of a shaft. In a structure that allows the rotor to be attached to the shaft by simply being put onto the shaft, assembly on the rotor's side can be easily performed.
