1. Could they use water to rinse the ore and rock that's just sitting there? 2. Could the crusher have an additional drive to spin the crusher "bell" in the direction of rotation as to distribute the wear more evenly?
Water increases the abrasiveness of aggregate. And, you get even wear throughout the mantle- no need for changing the direction. The pinion gear is cut in a way that wouldn't be too friendly for the gears if ran backwards. A lot of bad things would happen if you ran this hungry bastard backwards.
Man, when will they build a crusher that does not have build up like this one does. All crushers seem to have the same problem. Vibrate the hopper too.
They are designed like that so it’s ore on ore instead of ore running over the west media on the edge of the crusher pocket. You don’t want all that ore going into the crusher every time a truck tips.
@@KingsETLC Why would you want all that build up in the hopper? It means down time to scrape or clean the hopper of all those built up fines. If the crusher can not handle an entire load it is undersized for the job surely.
If you watch one all day everyday you’ll see that they get to a certain level of buildup and remain there like this one once the shedding angle of the ore is reached the whole way around the pocket. This as I’ve explained stops the ore from wearing out the steel walls of the pocket as the abrasions from every new load only occurs on the built up ore. I used to work for one of the most advanced wear systems manufacturers in the world and we deliberately designed this into multiple chutes, bins & pockets. wear media is expensive, the abundance of dirt they already have on site is not. Dirt on dirt wear is almost infinitely more efficient and economical than having a ‘clean & empty’ bin for someone to look at that’s worn out and needs relined every 12 weeks rather than just cleaned out with a digger and hoses for 6 hours before a shut so the crusher fitters can do what they need.
Excellent video, very impressive !

This crusher doesn't look it's being choke fed very well. Is mainshaft headspin an issue with the FLS gyros?

Water = dirty rock = less $$$

If the "bell" rotates, crusher will not crush...it has to move only radially to and fro...
Nice video footage, how many tonnes were tipped into the gyrator.
most of those big truck carry 400 tons
That crusher was playing peek-a-boo
You’d think the sides would be sloped enough to make sure all the rock went into the crusher
It beds up. When equipment cleans out the dump pocket there must be plenty of area for maintenance personnel
Keeps the wear cost down the rock protects the sides and bottom for free.
I realize I am kinda randomly asking but does anyone know a good website to watch new series online ?

@Ira Lennon Thanks, I went there and it seems to work :) I really appreciate it!

@@KingsETLC thank you, now it all makes total sense to me. I really appreciate that explanation.
See the red dot indians putting in rocks way to big? LOL not south american ones the asian ones!
