The invention relates to a device for dissolving compressed blocks of loose-fill cellulose thermal insulation material. The device includes a support surface for the compressed blocks of insulation and a cylinder with protruding members arranged on the cylinder mantel surface. Said cylinder is rotatable around a substantially horizontal axis to process and dissolve the compressed blocks of insulation between the protruding members and a processing zone arranged by an edge of said support surface. The invention discloses that said protruding members arranged on the cylinder mantel surface are elongated protrusions extending substantially parallel to the horizontal axis. The invention further discloses that the cylinder is arranged to rotate inside of an arc-shaped surface partly covering the cylinder mantel surface and prolonging the milling zone in a peripheral direction of the cylinder. Further, the invention relates to a loose fill insulation apparatus.

A combined crushing granulation drier has a combined tank, which is provided with a plurality of layers or a single layer. Two adjacent layers of tank bodies of the combined tank are connected by granulator connecting flanges. The granulator connecting flanges are arranged on the inner side of the combined tank. The ends of the flanges are fixed by bolts to form a fast-assembly type structure. A feed temporary storage bin is arranged at the upper part of the combined tank. The feed temporary storage bin and the tank body at the uppermost layer of the combined tank are connected, fixed and sealed by connecting flanges of the feed temporary storage bin. The combined tank is internally provided with a rolling unit. Each layer of rolling drum is internally provided with a rotating speed sensor.

A roller press capable of applying an electric field comprises a base, a frame (12), press rollers, an inter-roller distance adjustment device (11), a speed adjustment device (122), a voltage application device, a feed deflector (19), and a discharge device. A surface of the press roller is made of an electrically-conductive material, and an electric field is created when a voltage is applied to the press roller. In the roller press, an alternating or direct current electric field is applied between the press rollers to create an electrochemical action, such that particles or a solution in a system is induced to undergo a physical or chemical change, thereby enhancing interaction therebetween, and accordingly increasing grinding and dispersion efficiency of a solid-liquid dispersion system.

A cracker roller disc has a first portion radially outward of the centre of substantially constant thickness, and a second portion radially outward of the first portion which second portion tapers towards the periphery of the disc. A plurality of upstanding ridges extending radially outward across the second portion on opposed faces of the disc are machined to define respective conical surfaces forming radially extending edges on opposed faces of the disc. The disc is provided with one or more circular or spiral grooves which cut across the edges in a substantially perpendicular direction to the edges. The grooves extend the effective length of each edge.

A 3D-slanted roll crusher includes a housing, a number of driving devices mounted to the housing, a base mounted to an end of the housing away from the driving devices, a number of groups of grinders, a number of grinding teeth mounted on each of the grinders, and a number of material obstructing bodies mounted on an inner wall of the housing. The grinders correspond to the driving members one-to-one. Each grinder is connected to the base and the corresponding driving device. The grinders are spaced equally apart within the housing around a central axis of the housing and slantedly mounted on the base facing the driving devices.

A method of producing flour and/or semolina by raw material being fed into a feed opening of a roller press. The milling gap of the roller press is fixed, or damping of at least one of the rollers with respect to the lateral deflection is set, such that a first subset of the fill containing finer milling material forms a packed particle fill in the milling gap. In addition, the setting is carried out in such a way that individual particles of a second subset of the fill containing coarser milling material are in contact with the first roller and the second roller of the roller press. Subsequently, the bulk material is milled into milled product in the roller press (9) and the milled product is discharged through a discharge opening.
