Abstract

The present invention provides a method of handing abrasive solids materials used in an abrasive cutting procedure which jets a high-pressure abrasive slurry through a nozzle onto a work piece over and/or in a catcher tank. This handing method includes catching the used abrasive slurry together with work piece kerf material in the catcher tank, and passing at least some abrasive solids collected in the catcher tank as a slurry to a partitioning apparatus which includes a vibratory sieve. The handing method also includes partitioning the slurry with the partitioning apparatus in order to provide at least two solids streams. One of the solid streams passes through the sieve and the other passes across the sieve whilst entrained as a slurry. The handing method further includes passing as a slurry to the nozzle for jetting a pressurised or pressurisable slurry that has partitioned solids stream which has passed through the sieve.

FIELD OF THE INVENTION The present invention relates to a material processing method, a separation apparatus thereof, a partial recovery of an abrasive solid portion, and a related abrasive preparation for subsequent use. Second, prior art 'especially regarding the treatment of mud solid three-way separation cube material to provide at least one mud cutting plant, and any one or more of these process materials in the jet cutting process, the jet stream habit is used The abrasive solids of the required size, density, hardness and abrasiveness are used to enhance the corrosion of various workpieces placed between the nozzles of the jet stream and the collecting tank. Examples of abrasive materials include alumina, gold steel sand, copper slag, etc. Wait. The material handling of the grinding elements found in the water jet flow factory and the program includes those disclosed in the BH R Group's 20th page, published under the name "Jet Flow Technology".

It can be seen from prior art systems that attempts have been made to remove the solids that are too small in size while using the abrasives picked up by the collection trough together with the workpiece cuts. For this purpose, the conventional procedure uses both a hydrocyclone and a sieve. The liquid separator is subject to wear and tear, high maintenance costs, reduced recycling benefits for cost savings, reduced performance due to wear and the need for a large number of other disclosed systems to use the screen (see www.easi jet.com). SUMMARY OF THE INVENTION The present invention relates to abrasive materials for use in water jet stream cutting systems
