Benefits of technology
"The invention is about methods and arrangements for collecting dust in grinding machines. The technical effects of the invention include reducing the amount of dust and other material left on the surface being ground, which improves the efficiency of the grinding process and reduces the time required to complete a job. Additionally, the invention addresses the problem of dust obscuring the operator's view, allowing for consistent and efficient grinding. The invention also addresses the issue of heat generated during grinding, which can decrease the life of the tool. The grinding machine comprises a housing, a drive mechanism, a shroud, and at least one grinding plug with a working surface mounted in the head, and at least one channel extending from proximate the working surface into the plenum. The plug-type grinding machine comprises one or more individual shrouds for each grinding plug."
Problems solved by technology
A common problem that arises in grinding applications is dust or fines left on the surface that is being ground.
This becomes a problem in four ways.
This shortens the life of the grinding surface itself, as well as increasing the overall time to complete a particular job.
Second, the working surfaces of grinders are often cooled with water, producing a dust-water mixture called slurry.
Third, the dust left on the ground obscures the operator's view of the work surface.
It is difficult to achieve a consistent finish if the operator cannot judge the amount of material being removed.

A plug for a grinding machine includes one or more holes extending through to the plug for use as dust collection ports. A grinding machine includes a housing, a drive mechanism including a shaft extending through the housing, a shroud surrounding the shaft and abutting the housing to form a plenum, a head connected to the drive mechanism, at least one grinding plug having a working surface mounted in the head, and at least one channel extending from a position adjacent the working surface into the plenum.
Description
RELATED APPLICATIONS [0001] This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60 / 785,787, entitled “Device And Method For Extraction Of Dust From A Grinder,” filed on Mar. 24, 2006, which is herein incorporated by reference in its entirety.BACKGROUND OF INVENTION [0002] This invention relates to a machine and consumables for grinding surfaces, such as those formed of concrete, and particularly to an improved method for the collection of dust and other loose material generated as part of the grinding process. SUMMARY OF INVENTION [0003] A common problem that arises in grinding applications is dust or fines left on the surface that is being ground. Conventional systems, even those with relatively efficient dust extraction, leave a large quantity of dust and other material on the ground or other surface being treated. This becomes a problem in four ways. [0004] First, as a grinding process is being carried out, the grinding surfaces pass...
