Abstract
Abstract A method and apparatus for continuously mixing a liquid and a powder to form a substantially homogenous mixture. The liquid and powder are fed, via separate lines (22,21) to a cavity (7) in a rotating wheel (3,4) and to powder-accommodating spaces (13) respectively in said rotating wheel (3,4) and are thrown therefrom by centrifugal force outwardly towards the periphery of the wheel. The liquid is pressed from the cavity (7) via a gap (8,9) arranged in the wheel in a direction towards the upper side of said wheel and forms a mist curtain as it exits from the gap. The mist curtain captures the powder particles thrown by centrifugal force from the powder-accommodating spaces (13) and is mixed with said particles.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
A method of continuously mixing liquid and powder together to form a substantially homogenous mixture, characterized by feeding the liquid and the powder via separate lines to a cavity in a rotatable mixing wheel and to powder-accommodating spaces arranged in said wheel, so as to be thrown out towards the periphery of the wheel by centrifugal force, whereat the liquid is pressed from said cavity via a gap in said wheel in a direction towards the upper side of said wheel and, as it exits from the wheel, is thrown out towards a peripherally extending edge on the peripheral side of the gap to form a mist curtain, which captures the powder particles thrown out by the centrifugal force, whereat the mixture of liquid and powder particles are then thrown outwardly towards the periphery of the wheel and are caught by mixer pins in the housing of the mixer wheel, to form a homogenous mixture which is fed towards the outlet of the mixer housing.
Claim 2
Independent Claim
165 words
A method of continuously mixing liquid and powder together to form a substantially homogenous mixture, characterized by feeding the liquid and the powder via separate lines to a cavity in a rotatable mixing wheel and to powder-accommodating spaces arranged in said wheel, so as to be thrown out towards the periphery of the wheel by centrifugal force, whereat the liquid is pressed from said cavity via a gap in said wheel in a direction towards the upper side of said wheel and, as it exits from the wheel, is thrown out towards a peripherally extending edge on the peripheral side of the gap to form a mist curtain, which captures the powder particles thrown out by the centrifugal force, whereat the mixture of liquid and powder particles are then thrown outwardly towards the periphery of the wheel and are caught by mixer pins in the housing of the mixer wheel, to form a homogenous mixture which is fed towards the outlet of the mixer housing.
Claim 3
Dependent Claim
178 words
An apparatus for carrying out the method according to claim 1, comprising a mixer and a mixer housing (1, 2) and having separate lines (21,22) for supplying liquid and powder, characterized in that the mixer housing comprises a wheel arrangement (3,4) arranged for rotation on a shaft (5) in the mixer housing (1,2), whereat the liquid line (22) discharges into a cavity (7) in the wheel while the powder line discharges into powder-accommodating spaces (13) in the upper part of the wheel, and the cavity (7) communicates with the upper side of said wheel via a circumferentially extending gap (8,9) which opens out adjacent a circumferentially extending edge (14) located on the peripheral side of the gap, whereat the shape of the gap corresponds substantially to the shape of the outer surface of a truncated cone with the apex of said cone facing downwardly, and whereat the mixer housing (1,2) includes mixer pins (20) arranged to capture liquid from the mist curtain and the powder thrown out by centrifugal force from the powder spaces, to provide said mixture.
Claim 4
Dependent Claim
41 words
An apparatus according to claim 2, characterized in that the powder spaces (13) in the upper part of the wheel arrangement are separated from one another by means of blades (10) which are directed outwardly from the centre of the wheel.
Claim 5
Dependent Claim
43 words
An apparatus according to claim 2 or claim 3, characterized in that the cavity (7), which is located around the centre of the wheel arrangement, is divided into different compartments by means of blades (11) directed outwardly from the centre of said wheel.
Claim 6
Independent Claim
47 words
An apparatus according to any one of claims 2-4, characterized in that the conical gap has a lower (8) and an upper (9) conical part, of which conical parts the apex angle of the lower part is more obtuse than the apex angle of the upper part.
