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.

The system may include a milling apparatus configured to grind particles of the particle flow moving along the particle flow path to produce ground particles for the particle flow, and the milling apparatus being configured to reduce a size of the particles of the particle flow. The system may also include a sensor assembly configured to sense at least one characteristic of particles moving along the particle flow path, the sensor assembly utilizing near infrared (NIR) energy to sense the at least one characteristic of particles moving along the particle flow path.

The invention discloses a carrot drying and crushing integrated apparatus, which includes a working box and a feeding port located in the working box, the feeding port is opened upward, and the working box is fixedly provided with the feeding box. A shattering cavity under the mouth, a shattering device is provided in the shattering cavity, and a stirring and drying cavity located under the shattering cavity is fixed in the working box, and the stirring and drying cavity is provided in the working box. There is a stirring and drying device. The working box is provided with a pulverizing cavity located below the stirring and drying cavity. The present invention simplifies the processing and drying of carrots by using an integrated device in one step. This step saves processing costs. For the problem that the inside of the carrot is difficult to dry and the drying degree is inconsistent, the device solves the above problems by cutting and drying, and grinds the carrot directly through the pulverizing device. It is powdered to realize the integration of carrot drying and crushing.
