Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating.

The present disclosure relates to an apparatus and method for processing old concrete. The old concrete comprises cement rock and an aggregate, including sand and/or gravel. The method includes: grinding the old concrete in a grinding device; classifying the ground old concrete in a classifying device into at least two products of different grain fractions. The grinding is effected at a grinding pressure of less than 50 MPa. The apparatus includes a grinding device for grinding the old concrete, and a classifying device for classifying the ground old concrete into at least two products of different grain fractions. The grinding device is designed, and configured, in such a way that the grinding of the old concrete is effected at a grinding pressure of less than 50 MPa.

A water jet splitting chamber for waste tires has a chamber body, a water jet module, and an actuator. The chamber body has a retaining wall located in the chamber body to divide the chamber body into a splitting space and an actuator space. The water jet module is mounted in the splitting space, and has a slide seat mounted on the chamber body and at least one water jet seat mounted on the slide seat and being capable of linearly moving along a mounting direction of the slide seat. The actuator is mounted in the actuator space, and has a motor and multiple linking rods. The linking rods are driven by the motor and extend into the splitting space, and extending directions of the linking rods are along the mounting direction of the slide seat, and the water jet heads face toward the linking rods.

A grinding chamber of a grinding device for vegetal products suitable to form beverages includes, in its interior, a pair of grinders axially overlapping each other, one of which is rotatable with respect to the other which is kept stationary, a grinder support at least for the rotatable grinder, a motor member connected to the grinder support for setting the rotatable grinder in rotation. The grinding chamber is formed by a first bottom wall, perpendicular to the axis of rotation of the rotatable grinder, adjacent and below the support thereof, and at least a second cylindrical wall, connected axially to the first wall at the peripheral boundary thereof. The grinding chamber also includes a first opening for introducing the product to be ground and with a second opening for discharging the ground product. A labyrinth is provided between the peripheral boundary of first wall and the grinder support.

A modular system and method for producing urea from bio-mass includes means and steps for homogenizing a biomass feedstock stream having components with different bulk density BTU content into a stream having a consistent bulk density BTU content. The steps include cleaning the incoming bio-mass feedstock stream to remove non-organic matter, blending the cleaned bio-mass feedstock stream to obtain a homogeneous blend having a consistent bulk density BTU content, and milling the homogeneous blend bio-mass feedstock stream to a predetermined size no greater than 12 mm.

Methods of creating a batch of recycled glass from mixed color glass cullet. In one embodiment, the method includes receiving at a glass plant a weight and color composition percentage of a first batch of mixed color cullet. The glass plant also receives a weight and color composition percentage of a second batch of mixed color cullet. The weight and color composition percentage of the first batch and the second batch are combined to generate a combined weight and composition percentage. The combined weight and composition are percentage are used to generate, automatically at a glass plant, a formulation to produce glass of a desired color.

An electrode material containing active material powder is prepared. Dry classification of the electrode material is performed by a classifier. An electrode is manufactured by using the electrode material subjected to the dry classification. The classifier includes a mesh screen, a blade, and a motor. Breakage of the mesh screen is detected by monitoring either or both of an operation sound of the classifier and torque of the motor. The electrode material contained in the classifier will no longer be used for manufacturing of the electrode when breakage of the mesh screen is detected.

A machine for smashing thermosetting materials includes a high-pressure direct drive pump assembly, a mixing tank, a chemical solution tank, a hydraulic-control solenoid valve, a low-pressure auxiliary pump, a directional valve set and a controller. The controller, connected signally with the high-pressure direct drive pump assembly, the mixing tank, the chemical solution tank, the hydraulic-control solenoid valve, the low-pressure auxiliary pump and the directional valve set, is used to control opens and closes of the first directional valve, the second directional valve, the third directional valve and the hydraulic-control solenoid valve so as to supply the chemical solution in the chemical solution tank to the mixing tank.

Non-limiting embodiments of the present disclosure relate to a method comprising: obtaining asphalt shingle waste (ASW) and performing grinding, screening, and separating steps on the ASW. In some embodiments, granules are removed from the ASW. In some embodiments, the method transforms ASW into ASW powder. In some embodiments, the ASW powder is formed into a plurality of briquettes. In some embodiments, at least one of: the ASW powder, the plurality of briquettes, or any combination thereof is fed into a mixing process that results in an ASW powder filled coating. In some embodiments, the ASW powder is formed into an adhesive composition.
