Methods for cost effectively transforming lower quality silica sands into higher quality silica sands for use as proppants in fracking operations involving subterranean hydrocarbon formations. A process of exposing silica sand proppants to locally-sourced electromagnetic radiation, and systems therefor, are disclosed and shown to increase the performance of those silica sands as proppants in hydrocarbon formation fracturing operations.

A system includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the system can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.

An open-ended grinding mill (1) includes a drum (2) including a cylindrical shell (3), wherein the longitudinal axis (4) of the drum is arranged in a substantially horizontal position in a use position of the grinding mill (1). The drum (2) includes a first end (5) at the feed end of the shell and a second end (6) at the discharge end of the shell. The grinding mill further includes a bearing (8) supporting the drum at the second end, and a support structure (9) to connect the drum (2) to the bearing (8). The support structure is configured to provide a wall external to the shell, whereby the shell and the support structure provide a double-wall structure separating the bearing from the inside of the drum.

The present invention provides a system and method for more efficient utilization of comminution mills. Sensors are provided in the liners placed within the mill shell. The sensors may include RFID tags, liner wear profile sensors (e.g., such as an ultrasonic sensor), an inertial sensor (preferably included both an inclinometer and an accelerometer, and an acoustic sensor, among others. When the liners are installed in the shell, the RFID tag is used to register the location of the liner within the shell. In operation, the information provided by the sensors is collected by a data transmission unit and sent by transmitter over the air to a computer having an antenna and receiver for such data. The data is correlated and a processor generates data for display in regions on a display device.

The media-circulation type pulverizer comprising: an agitating member disposed in a lower region of a pulverization chamber; an annular partition wall disposed to extend upwardly in the pulverization chamber; and a media guide member provided on a lower surface of the end plate of the agitating member, wherein the annular partition wall has a height set to be to of a height of the pulverization chamber, and the media guide member has a lower end which enters a space of the inner region of the pulverization chamber located inside the annular partition wall, and wherein a vertically-extending flow straightening blade is provided between said lower portion of the media guide member and an upper portion of the annular partition wall, and the media separation member is provided on the lower end of the lower portion of the media guide member.

A thermal process for carbonizing hemp and reducing particle size, mechanically, by grinding or milling said carbonized hemp materials to generate a precise particle size hemp char and combining the hemp char particles with a polymer into a master batch.

A device and method for cleaning flowers and buds of plants of leaves and plant matter and particulate is provided. The buds are cleaned within a rotating drum having openings in a circular sidewall which rotates adjacent jets emitting gas. Freezing of the plant material and concurrent impacts from ice crystals formed by emitting gas, cleans the buds and flowers of unwanted plant material and particulate.

An agitator ball mill with a fluid circuit, which includes a grinding container and a casing container disposed around the latter uniformly spaced apart axially with a cavity formed between the containers. The fluid circuit is led at at least one flange through at least one flange lead-through introduced there, wherein a first opening of the at least one flange lead-through is constituted in a side wall of the corresponding flange lying orthogonal to the outer surface of the casing container.

An agitator ball mill including an in particular horizontal grinding container, which has a first end area having a grinding material inlet and a second end area having a grinding material outlet, and a method for operating an agitator ball mill. The agitator ball mill includes a shaft, which can be rotated in the grinding container or in the grinding chamber, respectively, by means of a drive unit and which is formed as agitator shaft at least in sections and which is equipped with agitator elements, as well as a separating device. The separating device includes a classifier rotor, which is arranged on the agitator shaft axially spaced apart from the grinding material outlet and has a rotatable rotor cage, as well as a screen unit, which is arranged within the rotor cage and which is fastened to the classifier rotor.
