Make sure there is a 2"minimum clearance between any part of the body and any stationary chute, hopper, or any of the support structure.Guards in-place. Pay particular attention to oil levels, breathers, pumps, line strainers, warning signals, and pressure hose assemblies. Refer to manufacturer's manuals.
Quarry dust
Oorkalan et al. (2020) combined quarry dust with coir pith as fine aggregate in fly ash concrete. It was observed that the increase in the quarry dust content from 0% to 75% by the total mass of fine aggregate, there was a corresponding decrease in the compressive strength of concrete, disregarding the composition of fly ash of the concrete.

Quarry fines minimisation: Can we really have 10mm …
Quarry fines, defined by the BS EN aggregate standards, are the inherent fraction of an aggregate passing 0.063 mm (63 microns). Many quarries also refer to their (sub-economic) fine aggregate (finer than 4 mm) as 'quarry fines' or 'quarry dust'. The term is used here to denote both fine aggregate and quarry fines. The

Partial Replacement of Fine Aggregates with Quarry …
Aggregates are divided into two categories from the consideration of size. Coarse aggregates Fine aggregates The size of the aggregate bigger than 4.75 mm is considered as coarse aggregates and aggregate whose size is 4.75 mm and less is considered as fine aggregates. All aggregates are to be sampled properly
EXPERIMENTAL STUDY ON PARTIAL REPLACEMENT OF FINE AGGREGATE WITH QUARRY
Quarry dust is a waste obtained during quarrying process. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. Also, the use of quarry dust as the fine aggregate decreases the cost of concrete production in terms of the partial replacement for natural river sand.
