2019 F60 Countryman
I bought my used 2018 F60 PHEV with the upgraded HK system. kept looking into speaker and amp upgrade for the current setup and went with a BAV SOUND speaker setup and it's bight and day to an already good but underpowered audio system. I hope to get an amp upgrade 1 day but it's not available yet for this version of BMW/MINI.

Cement Plant for Sale | Cement Plant Equipment Design
Old Cement Plant Upgrade. Through a series of technical upgrade, like replacing and upgrading the outdated equipment or redesigning and rebuilding the old production line, we can renew an old cement plant and make it meet the requirements of modern cement production.
1 Froth Flotation – Fundamental Principles
no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
Copper Flotation
The flowsheet in this study illustrates the modern approach to porphyry copper treatment throughout the industry. Each plant will through necessity have somewhat different arrangements or methods for accomplishing the same thing and reliable ore test data are used in most every case to plan the flowsheet and design the mill. Flotation of Copper ...
Feldspar Beneficiation & Flotation Process
Feldspar Flotation. All flotation is carried out in acid circuits, either with sulphuric acid or hydrofluoric acid both of which are highly corrosive to metal parts. For this reason it is necessary to use flotation machines with wooden tanks, partitions, hoods and standpipes, and molded rubber impellers and wearing plates.
Fine Gold Recovery by Flotation
Gold Flotation Column. The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was constructed.
Playing music through iPhone
As long as my phone is connected by Bluetooth I just hold down the voice command button and Siri shows on the VB screen and comes through the speakers. I have a 2016 Cooper with Visual Boost only - no enhanced Bluetooth or media pack.
Parametric Optimization in Rougher Flotation …
The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, which is mostly overlooked in …
MINI F56 Cooper S front brake upgrade 294mm to 330mm
The only difference between One/Cooper/Cooper D and Cooper S/SD brakes on the F56 are the calipers, caliper carriers, discs and pads. Splash shields are the same. As stated on the title of this thread, the standard disc size for Cooper S/SD is 294mm. One/Cooper/Cooper D models use 280mm discs.
Optimizing the Rougher Flotation Process of Copper Ore

Flotation Depressants
First let's change the amount of the Flotation Depressants used. The valuable mineral that isn't liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral's color.
