*_I live in Central Washington State on the 'Dry Side' - East of Cascade Mountains..._* We have 2 primary sources for aggregate; thousands of feet of Flood Basalt, and Alluvial Deposits caused when Anticlines formed in the Basalt's, lifting up and cut by rivers. Cubic miles of material was removed and deposited else where. Quarry operations occur on sides of Anticlines where exposed layers of Basalt are easy to access. Alluvial quarries are located along floodplains where hundreds of feet of eroded materials are easy to access. There have been several noteworthy landslides caused by taking too much material on the sides of Anticlines. Beds are tipped 45 degrees and there is interbed material in between. Gravel Pits along rivers could be dug much deeper, but after 50 feet below water table, it becomes too costly to continue running large pumps to keep quarries dry. I have never seen explosives ever used in either type of quarry. The Basalt's are weathered and break apart fairly easily. The cobbles, washed gravels, and sands from flood plains are easily excavated. Both quarry types will do primary crushing and screening. Several are part of larger Concrete, Asphalt, and Aggregate businesses. The Basalt's produce a range of aggregate sizes with good angular properties. The Alluvial material has to be crushed as it is too rounded from million years of erosion from rivers. There is a market for round river rock of different dimensions, but it is tiny compared to demand for engineered aggregates. Only blasting I have ever seen is in Cascade Mountains where Granite is dominate rock type. Road projects in steep high mountain passes require use of explosives before primary crushing which is usually done onsite. Because of high snow levels in passes, road work is limited to about 6 months per year. Some improvement projects have been going on for a decade or more. *_I know other quarry and blasting operations. Always get smile watching their videos._*
@@wdscepaniak Thanks for the comment. Aggregate is a billion dollar natural resource that few know much about. You have an awesome channel that informs the average viewer.
Awesome video awesome I like seeing rock, stone and other hard material being crushed. Nice camera angle perfect. Keep up the good work
Will do! Always risky to get the shots inside the crushing chamber but well worth it
Awesome video!
Thank you!

Awesome stuff! it would be cool to see how things are out there.

Can it be used as an aggregate for construction after crushing?
Yes, it can be used in concrete, asphalt, base and beyond
super video. i want see new video in 30 min, plizzzzz
Ok coming soon
Why are you running the feeder so slowly?
Just curious
We were down a loader that day
How's the wear with that quartzite? We have a quartzitic sandstone and it's nasty abrassive.
1.5, 3/4 and base?
Changing cone liners and jaw dies every other week. 1”,3/4” and 3/16” minus right now
@@wdscepaniak ouch, that's some nasty stuff!
defiantly hard on the hardware
