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.

A food grinding system with alternative power sources, including a food grinder, an electrical power source, and a manual power source mounted to or otherwise carried by a common base.

The present disclosure relates to a method for producing polycrystalline silicon fragments. The process includes (a) providing a polycrystalline silicon rod, (b) working the surface of the silicon rod by means of a hammer or needle hammer to remove at least a portion of a layer of the surface of the polycrystalline silicon rod, and (c) reducing the silicon rod to fragments. Wherein an amount of impact energy expended by the hammer and/or needle hammer is from 1 J to 15 J.

The present invention discloses a method and corresponding apparatus for separating lightweight materials from fabric pieces. The method comprises the steps of (a) introducing fabric pieces into a tumbling means having perforations for lightweight materials in the fabric pieces to be removed therethrough and coupled to a first source of negative pressure; (b) tumbling the fabric pieces in the tumbling means and simultaneously applying negative pressure from the first source of negative pressure to the tumbling means for removing lightweight particles detached from the tumbling fabric pieces from the tumbling means; (c) transporting the fabric pieces from the tumbling means to a top of a vertical separation chamber; and (d) applying forced air to the fabric pieces as the fabric pieces drop from the top to bottom of the vertical separation chamber by gravity for separating the lightweight materials from the fabric pieces, and simultaneously applying negative pressure from a second source of negative pressure to the vertical separation chamber to remove the lightweight materials separated from the fabric pieces from the vertical separation chamber; repeating this step until the fabric pieces are substantially cleared of any lightweight materials. The apparatus comprises a tumbling means and a vertical separation chamber.

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 the data is reviewable in real time while the mill is in running.

Generally described, the methods disclosed herein for recycling fiber composite source objects, such as wind turbine blades, include converting a whole wind turbine blade to an output material state that is useful for manufacturing other products, such as those used in construction of buildings, packaging, raw materials, and pellets, among other products. The recycling process is performed while tracking the progress and location of each wind turbine blade such that the direct source of the output material may be determined. In some embodiments, the method includes sectioning the wind turbine blades, crushing the wind turbine blade sections, tracking the progress of each blade through the process, and loading output materials into a suitable transportation vessel. Correlating each wind turbine blade to a quantity of output material provides several advantages, including various certifications of the material for uses with restricted or otherwise controlled products and materials, cost savings, and other advantages.
