A separation apparatus and method for separating ore is provided. The separation apparatus (10) includes a separation chamber (12) and is configured to be utilised with a fluid pulsing mechanism (32) for operatively pulsating a fluid through ore deposited in the chamber resulting in the migration of generally lighter ore particles toward an upper region (25) of the chamber and for generally heavier particles to migrate toward a bottom region (14) of the chamber (12). The ore is deposited by means of a chute (38) in the bottom region (14) of the chamber (12) and the lighter ore particles may then be extracted from the chamber through a first chamber outlet (24) while the heavier particles may be extracted through a second chamber outlet (28).

A fastening system for screening machines and/or setting machines for fastening replaceable screen lining segments and/or replaceable anti-wear elements in or to a screening machine having at least one frame which receives the screen lining segments and/or supports the anti-wear elements. For fastening of a screen lining segment and/or of an anti-wear element at least one adapter is fastened to the frame, the adapter having at least one magnet. The magnet interacts with the frame and/or with at least one ferromagnetic coupling element arranged in a vibration-proof manner in or on the screen lining segment and/or anti-wear element and in this way produces a magnetic connection between the adapter and the frame and/or between the adapter and the screen lining segment and/or anti-wear element. Additionally, a screening machine having such a fastening system.

A circular jig apparatus to allow cutting or marking of large circular holes in sheets of material using a tool with a cutting blade or marking device is disclosed. This apparatus includes a system to hold the hold the tool in place, adjust the size or radius of the circular hole, and guide the cutting blade or marking device around in a circle on the sheet of material. In particular the cutting tool may be a vibrating blade. A system is also disclosed to match the curvature of the cutting blade to the arc or radius of the circle being cut. A system is also disclosed to provide a depth stop for the cutting blade. A system to hold a wide variety of marking or dispensing devices for use with the circular jig is also disclosed.

A method and machine for the purpose of separating heavy materials from lighter materials by specific gravity. The machine consists of a vertical cylindrical body, supported on legs, and across the top a flexible diaphragm of appropriate material is draped, and fastened at the perimeter. The diaphragm forms a bowl-shaped depression, and is manipulated by a rotating assembly. The assembly having any number of arms, mounted in a fashion in which they are offset from the center of rotation, and extending radially nearly to the perimeter. The assembly is mounted on a vertical shaft which may be turned by a motor, or manually. The force of the arms, acting against the underside of the diaphragm, causes an upward projecting, moving wave in the diaphragm. Raw material is fed through a feed funnel to the center of the diaphragm, forming a conical pile. The pile is agitated by the moving wave, causing the heavier materials to sink down to the upper surface of the diaphragm while the lighter waste moves down and across the pile, and over the edge. The machine operates either with, or without water. The heavy materials, once in contact with the surface of the diaphragm, move down the slope of the diaphragm to the center. The heavy materials are encouraged to move more quickly and positively to the center by the offset nature of the arms, which cause a sweeping action to the materials in contact with the diaphragm. The sweeping action also assists in holding the heavy material at the center, and preventing its return to the waste stream.

A jig concentrator includes a jigging bed with a plurality of holes, a flow control valve associated with the jigging bed to regulate the flow of fluid, and a pulsation housing connected to the flow control valve to control the pulsation of water or another medium. The flow control valve is located beneath the bed. A water or fluid inlet is connected to the pulsation housing to introduce water into the apparatus, and a pressurized air buffer is mounted on the water inlet to buffer and store air in the jig concentrator.

An artificial mulch cleaning system includes a vehicle with a housing having a front end, a back end and a plurality of wheels. A collecting assembly is attached to and extends forward of the front end. The gathering assembly has a distal end with respect to the front end. The distal end engages and captures rubber mulch positioned on the ground surface. A cleansing assembly is mounted on the vehicle rearward of and in communication with the collecting assembly. The cleansing assembly cleans the rubber mulch brought into the vehicle by the collecting assembly. A spreading assembly is attached to vehicle and is in communication with the cleansing assembly such that the spreading assembly receives the rubber mulch from the cleansing assembly. The spreading assembly dispenses the rubber mulch from the back end of the vehicle.
