An intake arrangement (1) for a roller mill which includes a storage container (2), a force transducer (6) arranged on the storage container (2), a level sensor (7) arranged on the storage container (2) for determining when a ground material level (B) is reached in the storage container (2), and a control unit (8). The control unit (8) is designed to determine a first fill level (A) of the storage container (2), from a weight force (EG) determined by the force transducer (6), and to determine a characteristic fill level curve (K), based on the determined first fill level (A) and the fill level (B) determined by the level sensor (7).

A roll machine for milling includes a tube type supplying unit 16, feed rolls 19, 20, a feeder gate plate 21, and main rolls 4, 5. A load detector 28 for detecting stock level is provided on inlet part 16a of the tube type supplying unit 16, a detection rod 29 for detecting the level is suspended in the tube type supplying unit 16, and one end of the detection rod 29 is connected to the load detector 28.

A distribution metering device (1) for a roller mill which includes a housing (2) with at least one grinding stock inlet (3), at least one grinding stock outlet (4), and a feed roll (5) which is arranged in the housing (2) for metering grinding stock into a grinding gap of the roller mill through the grinding stock outlet (4). The feed roll is rotatable about a feed roll axis (SA). A conveyor shaft (6) is arranged in the housing (2) for distributing grinding stock along the feed roll (5). The conveyor shaft is rotatable about a conveyor shaft axis (FA). The conveyor shaft axis (FA) is substantially parallel to the feed roll axis (SA), and a first fill state sensor (7) is arranged in the housing (2) for ascertaining a first grinding stock fill state of the housing (2).

This disclosure relates to a high pressure grinding roller stud comprising two materials of different hardness, and a high pressure grinding roller incorporating at least one such stud.

A method and apparatus for grinding a particulate material is disclosed. The method may include providing a system including a roller mill apparatus and a hammermill apparatus, operating the roller mill apparatus and the hammermill apparatus, adjusting a feed rate of particulate material to the roller mill apparatus until power consumption by operation of the roller mill apparatus achieves a target power consumption for the roller mill apparatus, and adjusting a gap between mill rolls of the roller mill apparatus until power consumption by operation of the hammermill apparatus achieves a target power consumption for the hammermill apparatus. The system may include roller and hammermill apparatus with sensing and controlling apparatus configured to operate the roller and hammermill apparatus according to the methods disclosed.

A system for grinding material in a material flow through the system may include a feed hopper having an interior for receiving material to be processed, a feed apparatus configured to receive material of the material flow from the feed hopper and control a feed rate of the material moving through the system, a roller mill apparatus configured to grind material of the material flow passing through the roller mill apparatus, and a classifier apparatus configured to remove portions of the material from the material flow.

A canola seed sample crusher features a frame, and a drum rotatably carried on the frame and having an array of seed pockets on an outer periphery thereof. The seed pockets are sized and shaped to receive individual canola seeds respectively therein. A pathway is arranged to receive a length of adhesive tape and guide the tape over the seed pockets in the outer periphery of the drum during rotation thereof to adhesively collect the sample of canola seeds from the seed pockets onto the adhesive tape. A crushing mechanism is carried on the frame and operatively installed at a position along the pathway to crush the sample of canola seeds collected on the adhesive tape during passage of the tap tape through the crushing mechanism.

An apparatus for grinding particulate material having a roller press having a pair of grinding rollers each having a rotation axis and being arranged oppositely and parallel to define a grinding roller gap in a common plane through the axes of the rollers, and a mechanical conveying device for conveying granular material to the roller press having a proximal end and a distal end relative to the roller press, the roller press being arranged at the proximal end of the conveying device. The conveying device is arranged to constrain a flow or mat of the granular material having in a cross sectional view a rectangular shape with a mid-plane and to transfer the flow or mat of granular material directly to the grinding roller gap of the roller press in a linear transfer plane being coincident with the mid-plane and perpendicular to the common plane through the axes of the rollers.

Process for manufacturing a blow-in insulation material made of straw, including a processing step in which the straw is crushed between rolls in a crushing apparatus, a crushing nip in the crushing apparatus being selected in such a way that the straw nodes are crushed during the crushing operation.

System and method for controlling the startup sequence of a roller crusher is disclosed. The roller crusher includes two generally parallel rollers that are separated by a gap where the rollers rotate in an opposite direction. During startup, the gap between the rollers is greater than the gap during normal production and a feeding arrangement is run at a speed that is lower than a normal production feed rate. The rollers are rotated at a predetermined speed that is less than the speed during normal production. Other parameters of the system are set such that material is fed over the entire length of the rollers and the no crushing force is exerted during the startup. The method and system of the present disclosure reduces the amount of stress on the rolls, frame and hydraulic system of the roller crusher.
