Embodiments relate continuous process for treating tailings that includes providing tailings for treatment having at least 20 wt % solids, providing a mixing apparatus having a first inlet for feeding the tailings, a second inlet for feeding flocculants, an outlet for a mixture of the tailings and flocculants, and a rotating disk, the first inlet being separate from the second inlet, the second inlet being above the rotating disk, and the rotating disk having a tip speed at least 2 m/s, continuously introducing into the mixing apparatus the tailings through the first inlet and the flocculants through the second inlet, allowing the tailings and the flocculants to mix on the rotating disk to form the mixture of the tailings and flocculants, continuously removing the mixture of the tailings and flocculants through the outlet to form a treated mixture, and flowing the treated mixture from the mixing apparatus for further treatment or to a disposal area.

A slurry mixer for a battery electrode capable of maximally simplifying a configuration of a high-speed stirring body to minimize a rotational load, such that a stirring time of the slurry may be greatly reduced and productivity may be increased, preventing a powdery material from being accumulated on an upper side face and an upper surface of a low-speed stirring body, preventing a deterioration in a performance, failure and a reduction in a life span of a high-speed stirring shaft and bearing, and uniformly stirring mixed materials located at inner corners and a bottom of a container, thereby further increasing stirring efficiency.

Disclosed are a process and system for preparing a catalyst slurry. The process can include preparing a catalyst slurry comprising a solid particulate catalyst and a carrier liquid in a catalyst slurry preparation system. The catalyst slurry preparation system can include a mixing vessel, a rotatable impeller system connected to the mixing vessel, and a motor connected to the rotatable impeller system. The rotatable impeller system can include an agitator shaft and a hub connected to the agitator shaft. The hub and at least a portion of the agitator shaft are positioned within the mixing vessel along a longitudinal axis of the mixing vessel, and the hub has at least three blades.

A dual chamber assembly for continuously injecting slurry into a wellhead by displacing it from chambers with pressurized clean fluid.

A mixing and dispensing container for mixing and dispensing dental materials. The mixing and dispensing container includes: a plunger; an open-ended liquid receptacle adapted to receive the plunger; and a main body with a proximal end, a distal end, a chamber open at the proximal end and an aperture in the distal end. The chamber is adapted to receive the liquid receptacle. The dental capsule mixes various components of the dental materials and forms a dental paste for dispensing. The container is especially envisaged for use in mixing of components to provide a paste for dental use.

One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste, the device having a cartridge having a cylindrical interior. The interior of the cartridge is closed on the front side except for a delivery opening for expelling the bone cement paste. A delivery plunger is arranged in the interior of the cartridge. The cement powder is arranged in the interior of the cartridge. A closure is arranged on the front side of the delivery plunger. The closure closes the delivery opening when the delivery plunger is pressed against the front side of the interior of the cartridge. The closure blocks a further movement of the delivery plunger so that the delivery plunger is spaced from the front side of the interior of the cartridge at least in some areas and a dead volume remains in the interior of the cartridge when the delivery plunger is pressed against the front side of the interior of the cartridge.

A slurry mixing device includes an installation frame, a slurry mixing tank, a slurry feeding tank, a cooling mechanism and a slurry discharging mechanism. The slurry feeding tank is movably arranged under the slurry mixing tank, the cooling mechanism and the slurry discharging mechanism. A mass scale is arranged under the slurry feeding tank. A stirring cavity is formed in the slurry mixing tank, and a stirring paddle is arranged in the stirring cavity. A stirring motor is arranged on the slurry mixing tank. An outlet is arranged on the bottom of the stirring cavity. An oil bath cavity is formed between the slurry mixing tank and the stirring cavity. The cooling mechanism includes a lifting cylinder and a lifting base. The lifting base is provided with a rotating paddle and a rotating motor. The lifting cylinder is arranged on the installation frame.

A method for the manufacture of foamed plaster utilizing a mixture of powdered casting plaster, powdered limestone and hemp fibre. The mixture is fed into a Venturi apparatus (40) under the influence of gravity. Compressed air may be supplied to the Venturi apparatus (40) through an inlet pipe (41) causing air and solid particles to be sucked into the Venturi apparatus (40). The elongated tube is provided with an inlet nozzle arranged to receive a mixture of water mixed with detergent agents. Further, the tube (50) is provided with an inlet nozzle (56) arranged to receive compressed air such that the elongated tube (50) delivers the mixture to a mixing and spray head (60) so as to feed the resulting mixture to a moulding means.
