Preloading a plurality of feed types of a feed mix for livestock in a mixing plant. Feed types are conveyed towards a mixer. Bunkers selectively discharge one of the feed types on a loading conveyor. A controller controls a preloading weight of the feed types to be discharged onto the loading conveyor. Feed types are individually discharge onto dump spots of the loading conveyor at the bunkers and terminate when a predetermined total weight is reached or interrupt when a maximum preloading capacity is reached or feed reaches the end of the loading conveyor. Feed types may be individually discharged from the bunkers onto the dump spots and the main component loaded into the mixer by a loading vehicle, such that the weight of the main portion and the weight of the supplemental portion add up to a programmed total weight of the main component.

A particulate material sensing and agitation control system of an agricultural system includes a drive system configured to operate an agitating system, a plurality of sensors, in which each sensor of the plurality of sensors may detect presence of particulate material at the sensor, and a controller. The controller is configured to determine a functional status of each sensor of the plurality of sensors, and, in response to determining the functional status of a respective sensor of the plurality of sensor is functioning, determine a detection status of the respective sensor. The controller is further configured to output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on a position within the agricultural system, the functional status, and the detection status of each sensor of the plurality of sensors.

A method for manufacturing slurry for an insulation protective layer of a rechargeable battery includes obtaining an insulation material calibration curve showing a relationship between particle size and compressibility of an insulation material using sets of particle size and compressibility of the insulation material, obtaining a binder calibration curve showing a relationship between particle size and compressibility of a binder using sets of particle size and compressibility of the binder, measuring particle sizes of the insulation material and the binder loaded, determining an optimal mixture weight ratio with reference to the curves so that compressibility of mixture powder of the insulation material and the binder equals a set compressibility based on the measured particle sizes, mixing the insulation material and the binder at the determined mixture weight ratio to form mixture powder, loading the mixture powder into a powder dispenser, and adding a solvent to the mixture powder.

An apparatus and method for automatically preparing a mixture of particles of two or more substances such as but not limited to raw tobacco and raw medical cannabis flowers in one or more receptacle where the mixture proportion is predefined, is disclosed. The apparatus of the invention can be used for mixing any types of herbal substances. Moreover, the apparatus of the invention can be used for mixing one or more kinds of the same substance, for example mixing two or more kinds of marijuana strains. The apparatus includes one or more compartments for inserting each of the substances separately. In some variations of the present invention the size of at least one of the compartments is smaller for predefined smaller quantities of raw herbal material for example, a single marijuana flower.

An inclined belt conveyor capable of mixing particulate material, such as agricultural seed or fertilizer. Inserting a plurality of mixing baffles into the stream of the particulate material induces a backflow of the particulate material. In the case of wet, freshly treated plant seed, this backflow causes a mixing, polishing, and drying of the plant seed. The mixing distributes the seed treatment into an even coat by rubbing the individual seeds of the seed flow stream together. The inclined belt conveyor may also be used to blend multiple varieties or types of particulate material. The mixing baffles are oriented to induce backflow and sideways lateral movement and may incorporate a passage to allow increase particulate material flow rate. The mixing baffles can selectively deploy between an angle of 20 degrees to 70 degrees to enable the mixing inclined belt conveyor to have a transfer-speed-maximizing mode and a mixing mode.
