A coal and gangue identification device is disclosed. The device includes a rotary supporting frame, a water injection unit, a weighing unit, a liquid level detection device and a processing module. The rotary supporting frame is provided with a loading unit used to load a mineral aggregate. The rotary supporting frame is used to drive the loading unit to rotate on a horizontal plane. In the rotating process of the rotary supporting frame, the loading unit cyclically passes through a water injection region, a material adding region, a volume measurement region and an unloading region which are sequentially disposed on a rotation trajectory of the rotary supporting frame. The water injection unit is used to inject water to the loading unit of the water injection region.

A system and method for flaking. The system includes a stationary roller, and moveable roller, and an adjustable fixator applying tension between the stationary and moveable rollers. The fixator includes a pressure transducer and a linear indicator. The transducer and indicator allow the fixator to read pressures and make fine adjustments to the fixator to obtain a desired gap between the two rollers.

A controller may receive information identifying an area of interest from a plurality of candidate areas of interest including locations on the machine and external to the machine. The controller may obtain, using the one or more first sensor devices, data identifying material located at the area of interest; and generate a graphical representation based on the data. The controller may determine, using the one or more second sensor devices, at least one of a position or an orientation of one or more portions of the machine; and identify a portion of the graphical representation based on the at least one of the position or the orientation of the one or more portions. The portion may correspond to the material located at the area of interest. The controller may determine, using one or more computational models, a volume of the material based on the portion of the graphical representation.

A device including a housing having an access opening, a swing arm mounted to the housing and configured to be selectively pivoted toward and away from the access opening, and a closure captured by the swing arm. The closure can be configured to be selectively moved in a substantially vertical motion relative to the swing arm between a retracted position and an inserted position at least partially in the access opening and can have locking features for cooperating with engagement features in the device to move the closure into a closed and sealed configuration.

Disclosed are methods, materials and devices for approximation of blood volume in a fluid, such as in a biological fluid collected during a surgical procedure. The method and devices include the use of a RBC flocculant, such as polyDADMAC, and an approximate blood hematocrit for the type of animal, as well as a calculated RBC packing ratio corresponding to the collection device being used. Also provided is a Blood Indicator Panel (BIP), comprising a series of markings calculated from an observed red blood settlement volume, the average animal type hematocrit, and a calculated RBC packing ratio “η” value for the collection device. Pediatric (about 200 ml or 250 ml size container), adult human (about 1,000 ml-1,500 ml) and veterinary (about 500 ml-2,500 ml) collection containers are also disclosed, that include a RBC flocculant, for use in approximating blood volume in a fluid.
