Silly Questions About Any SpeedMixer™
Ever had what you consider a 'silly question' that you dare not ask out loud?
Maybe you don't ask questions out load in a work environment, thinking everyone should will know, yet you don't.
We look at this as our issue, as it's not your fault you do not understand because we did not cover this in our free competancy training. If it's a question about a DAC or SMART-DAC SpeedMixer® then it's important we put that right - quickly.
Maybe you were not there at the time or it was'nt explained in a way you under stood. Bad training / no training / bad boss scenario can strike too😉. We've ALL been there!
We're here to help, assist and not to judge. Our free of charge competancy training is available to ANY new or existing user of a Hauschild SpeedMixer®. It doesn't matter about the age of the SpeedMixer™ as these last decades. Neither how clean it is, as long as it's still in operation.
Here's some common questions covered for you now :-

Is a DAC Hauschild SpeedMixer® safe ?
YES. Every one was / still is made to order, precision engineered and built by hand in Germany. They should run quietly and smoothly and not move around providing the minimum and maximum weight's are observed.
THEY ARE - SAFE - RELIABLE - FAST + OURS DO NOT BREAK
We expect ANY Hauschild SpeedMixer® when regularly serviced by a Hauschild Engineer using OEM component parts to have a service life of 10-15+ years.
How often should a DAC be serviced?
We strongly suggest a SpeedMixer™ service every 12-18 months depending on use, weight, load, RPM speed and hours of opperation.

Weight vs Volume
If we take tap water as an example everyone knows and understands.
100ml of tap water weighs 100gm. This is a ratio of one to one (written 1:1).
1ml of tap water = 1gm
500ml of tap water = 500gm
1000ml of tap water = 1000gm or 1kg (kilo).
Tap water has a weight to volume ratio of 1.0 (500ml = 500gm)
This density is called the 'specific gravity' (S.G for short). S.G is simply a way of describing the density to volume.
Tap water has a specific gravity of 1.0. We write this technically as S.G=1.000
An S.G of 1 means 1 lite per kilo.
Milk has an S.G of 1.028-1.033, so milk is heavier than water.
Ketchup has an S.G of 1.15 so it is heavier than milk.
Aluminium metal has an S.G of ~2.7
Copper has an S.G of ~8.95
Silver has an S.G of ~10.49
Gold has an S.G of ~19.3 - simply put, you would need more than 19 times the equivalent volume of water to have the same weight in gold.
Every different type of liquid, powder, solvent, paste, putty and clays have a different S.G.
Viscosity
Viscosity is the technical term used to define how runny or thick a liquid is.
Tap water is thinner than car engine oil for instance. Both are 'runny' BUT water is thinner than oil. Oil is more 'viscous' (thicker), less runny some might say.
S.G and Viscosity
Problems face the world when mixing materials that are different.
The S.G and viscosity can cause problems. Ever mixed flour, eggs and milk together to make a pancake mix ?
You will understand then. We will also agree that each individual ingredient (products) of our pancake mix are different.
You could term these as different products, or 'dis-similar products'. We prefer in the industrial world, to use the term 'dis-similar materials'.
Imagine three plastic 1 litre pots. Each were, empty the same weight and their volume, dimensionally and volumetric-ally identical.
If you filled one to the top with milk, one with flour and the other with eggs. Which would be heavier ?
If you had filled the pot with sieved flour and weighed it you would get one weight. If you pressed the flour down with the back of a spoon, it would squash the flour and you could get more in. If you did this again and again until the pot was full, flat on top and then weighed it, it would be much heavier than the first one yet. You'd expect this but the volume (mass of the pot) would be the same.
Hard to describe so this is where S.G comes in handy.
The first example:
Once you have completed the first mix your chosen material types. With some basic controls, this mixing process can easily be repeated, the finished product will be the same every time. Time after time.
We have simplified these into three series, each based on the amount they are designed to mix.
Weight alone can be confusing so we've detailed the volumes the SpeedMixers containers will hold.
