The present invention regards a refiner plate segment (1) for a disc-type refiner apparatus (30), adapted to grind a saturated cellulosic material (M) in a refining gap (17) defined by opposed discs (20) during use of the apparatus (30), the material being moved from a refiner inlet opening (21) towards an outer edge (7) of the segment (1). The outer edge (7) of the segment (1) comprises a barrier arrangement (15) to increase the pressure in the refining gap (17) for retaining the liquid phase out to said outer edge (7). The present invention also regards a method of refining a saturated cellulosic material (M) in a refining gap (17) defined by two opposed discs (20) of a disc arrangement.

An apparatus for dispersing or refining organic material includes a rotor shaft extending along a rotation axis, a rotor to be driven to rotate by the rotation axis, and a housing arranged around the rotor shaft and the rotor, the housing having an inlet for receiving the organic material and an outer wall. The housing has a stator disc, and the rotor has a rotor disc, each disc having teeth on a surface that is turned toward the other disc. After organic material has been dispersed by the teeth, the organic material is fed into a dilution zone where the organic material is mixed with dilution liquid introduced through a number of dilution inlets before the mix is fed out of the apparatus via an outlet arranged in the outer wall. The dilution inlets are angled in relation to the radial of the rotation axis, in a plane perpendicular to the rotation axis. By angling the dilution inlets in such a way, a better mix is achieved between dilution liquid and dispersed or refined organic material, which results in increased energy efficiency of the apparatus.

The present invention concerns a granular material conditioner for optimising grain sizes of granular materials comprising two discs which are rotatable relative to each other and which are arranged in substantially mutually parallel relationship, a granular material inlet through which granular material can be passed into the conditioner into an annular gap between the two discs, and a catch container for receiving the granular material which issues from the gap between the two discs by virtue of centrifugal force. According to the invention it is proposed that the catch container has an elastic curtain, wherein the curtain is spaced at least portion-wise from the catch container wall and limits the trajectory of the granular material issuing from the gap.

An experimental device for SDC of powder particle sizes in a disc mill system includes a screw feeding control device, a mill speed adjustment device, a disc gap servo control device, a sampling device, a laser particle analyzer, a control cabinet and an upper computer. A control method for the experimental device includes the following steps: 1) performing initial setting; 2) starting the disc mill system; 3) performing sampling through a sampling device; 4) detecting a actual PDF (probability density function) shaping of distribution of powder particle sizes through the laser particle analyzer; and 5) updating the initial setting through a SDC algorithm. The experimental device and method can verify a series of SDC algorithms, and provides good a better experimental platform for teaching and scientific research; and the shape of non-Gaussian distribution of output random variables of a stochastic distribution system can be effectively controlled.

A viscous food dispensing system includes a chute inlet configured to funnel particulate food product into a sleeve and a transport device having an over-center cutout. The transport device is configured to rotate within the sleeve to convey the particulate food product. A processing surface extends downward from the chute inlet towards a curved base of the sleeve along a portion of the transport device. The processing surface is spaced laterally apart from the transport device to define a processing zone between the processing surface and the transport device. The particulate food product is processed as the particulate food product is captured between a leading edge of the over-center cutout and the processing surface while the transport device is rotating.

The subject of the present invention is a method for processing electrical and electronic components in order to recover valuable materials, such as the metals contained in printed circuit boards. According to this method, the electrical and electronic components are pre-shredded mechanically and then mixed with a liquid before they undergo wet milling (5).
