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.

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 portable, modular mini mining jig can be configured as a single-stage jig with one or multiple jig cells, or as a multistage jig with one or multiple jig cells per stage. Due to the modular nature of the mini jig components, any number of jig cells and stages are possible. Adding jig cells and stages increases the throughput and capacity of the system, which increases efficiency.
