Upgrading an Old Dell Video


Got an old Dell PC that I have setup dual-boot Linux/Win 10, principally used for A/V but was unable to connect to big screen because it had no HDMI port. Attempted to put a newer video card in it that I had lying around but it took more power than the 375 watt power supply could provide. And then recent kernel upgrades broke nouveau in a way that the sync rate no longer worked with the monitor. So I found an old ATI Radeon card at Re-PC for a whole of $19 that was light enough in power requirements to work in this machine but which had HDMI so I can connect it to the television. And as a bonus, the device drivers in Linux work correctly with it so it's displaying good under Linux again. This machine is one of the early dual core Athlon CPU based machines yet it provides adequate performance for it's function. The power supply is only 375 watts but is a non-standard form factor so I can't easily replace it. At one point I was just going to move the whole thing to a new case, but then discovered the motherboard is laid out backwards for an ATX so that was a no-go. Gotta love Dell engineering. But it just keeps on ticking.

The Differences Between Asphalt Batch Mix Plant and Asphalt Drum Mix Plant?


Asphalt Batch Mix Plant: After being poured into suitable hoppers according to the particle size, the cold aggregates are conveyed by a conveyor belt to a vibrating screen, where the cold aggregates with particle size larger than 4 cm are filtered out, and other cold aggregates are sent to the drying drum by a diagonal belt conveyor. Hot aggregates enter the elevator from the burner end of the drying drum after being dried and heated. With its help, hot aggregates reach the vibrating screens. Depending on the size of the mesh, hot aggregates are sieved to different silos. Through accurate weighing, the hot aggregates in different silos are batched into the mixer according to the ratio designated ahead. At some time, the mineral powder also falls from the screw conveyor, and the heated liquid bitumen also sprays from the nozzle. After mixing, the finished mixture is produced one batch by another.
Asphalt Drum Mix Plant:The drying drum of the continuous asphalt plant has functions of drying, heating, and stirring. The cold aggregates go into the non-stop rotating drum from the hoppers via a conveyor belt, in which cold aggregates are dried and heated in sequence. The nozzle in the drying drum continuously sprays the bitumen, and the mixture comes out unintermittedly with the drum rotating.
