摘要： In a method for regenerating a lithium precursor, a cathode active material mixture that includes an active material powder including lithium composite oxide particles and dust particles is prepared. The dust particles are separated from the cathode active material mixture using a classifier to collect the active material powder. The active material powder is reduced to form a preliminary precursor mixture. A lithium precursor is recovered from the preliminary precursor mixture. The lithium precursor can be obtained with high purity and high yield.

摘要： A modular nut cleaning plant comprises a nut sizer and a stick remover mounted to the nut sizer. A vacuum unit is mounted to the stick remover. A nut product stream will pass on the stick remover through the vacuum unit which will vacuum light debris from the nut product stream. The nut product stream moves on a chain on the stick remover. Large debris and sticks that do not fall through openings in the chain will pass into a debris conveyor. Nuts and debris that fall through the openings in the chain will be delivered to the nut sizer. The nut sizer will rotate and tumble nuts and debris in the nut product stream. Nuts of an undesirable size and debris will pass into a debris conveyor. Nuts of a desired size will pass through the nut sizer into a chute or other conveyance to be delivered to further nut processing apparatus.

摘要： An apparatus and method for the dry separation of bulk particulate material, especially coarse particles, is provided. The apparatus comprises a chamber, a screen adjacent the chamber and a fluidising device fluidly connected to the chamber. The screen has a screen surface, a plurality of apertures and an opening larger in size than the aperture. A mixture of the coarse particles and a fine particulate medium is fed into the chamber. The fluidising device directs a fluidising fluid to fluidise a fine particulate medium and create a fluidised bed directed towards the screen. The fine particulate medium and the coarse particles pass from the chamber through the openings. The fine particulate medium passes back through the apertures to the chamber. Relatively high density coarse particles also pass back through the openings to the chamber. Relatively low density coarse particles are retained on the screen surface. Vibrations may also be used.

摘要： A process for reforming the fly ash, including the heating step that heats a raw fly ash powder containing the unburned carbon at a temperature of 780 to 1000° C. to decrease the amount of the unburned carbon contained in the raw fly ash powder; and the cooling/classifying step that introduces the heat-treated fly ash in a state of being maintained at a high temperature as obtained through the heating step into a cooling/classifying apparatus so that the fly ash is separated into a fine grains and a coarse grains; wherein the cooling/classifying apparatus 3 used in the cooling/classifying step has a basic structure in which the gas flow for classification is introduced from the lower side and the gas flow Z for cooling/classification introduced into the apparatus is then discharged from the upper side; the heat-treated fly ash is brought into contact with the gas flow Z for cooling/classification, the fine grains contained in the heat-treated fly ash is lifted up and discharged out of the apparatus while the coarse grains contained in the heat-treated fly ash is allowed to stay in the apparatus 3, and the fine grains and the coarse grains are separated and cooled; and the fine grains discharged from the apparatus 3 is recovered by using a dust-collecting apparatus, and the coarse grains is recovered from the apparatus 3.

摘要： The separator according to the invention comprises: a tank (1) for receiving waste material and containing fluid to separate waste material by density into floating and settled material; automatic feed means (18, 37), for example, a double screen (18) to feed waste material to the tank (1); motorised conveyor belts (3, 4) divided into a floating waste material conveyor (3) and a settled waste material conveyor (4) to extract floating or settled waste material from the tank (1): and a blower-type sorting device (21) comprising: a turbine (22) that provides an airflow; and a branched duct (23) divided into: a riser duct (26) to transport part of the airflow to a diffuser (39) beneath the automatic feed means (18, 37) to raise light-weight waste material; and a discharge duct (27) to transport and horizontally expel another part of the airflow in order to remove previously raised waste material. The separator according to the invention may incorporate bubble-making means, with injectors (2) to facilitate floatability and remove floating waste material.

摘要： A heavies removal device including a frame supporting a transporter, a perforated sheet, and an opposing weight. A plurality of upper arms pivotally connect the transporter with the frame and a matching number of lower arms pivotally connect the opposing weight to the frame. Air is directed through the perforated sheet. A drive assembly, including a motor and an eccentric bearing, drive the arms in an upward and forward fashion. As lamina is fed onto the infeed end of the perforated sheet, each forward stroke of the upper arms throws the lamina upward and forward toward the discharge end of the sheet. Vanes on the perforated sheet direct the air as needed to the forward of the sheet to achieve the desired transport. The heavies are transported to the discharge end of the device where they are removed and may afterward be sent through to the next phase of processing.

摘要： A spring assembly includes a resilient member having a first and second end shanks and a central helical portion. The first end shank extends in a first direction from the central helical portion, and has a longitudinal axis from a proximal end to a distal end. The second end shank extends in a second, opposite direction from the central helical portion, and has a longitudinal axis from a proximal end to a distal end. The central helical portion includes one or more coils disposed about a central longitudinal axis, and has a first end attached to the proximal end of the first end shank and a second end attached to the proximal end of the second end shank. The axes of the shank ends and the axis of the central helical portion are parallel or are collinear. The assembly also includes an attachment site at each of the end shanks.
