Now here's the rub. Mixer companies overheads and profit margins are directly dependent upon the perceptions of the "Mixing Black Box", regardless of the actual product or brand. To be direct, this has defined our market niche regardless of whether the design is special or not, as we handle the range of application types.
Breaking it down to a common sense level, if we were to apply the commonly accepted 80/20 rule (actually mixing is more like 90/10) to all mixing applications, what would result is that 90% of all mixing applications are straightforward or common. These common applications are generically referred to as FLOW CONTROLLED mixing applications. Directly stated, in more precise language, a flow controlled application will require more of a commodity-type-in-stock-mixer. Specialty applications will most certainly be more costly special designs. So, based on the simple 80/20 rule, it may be in your best interest to clearly classify (understand) your mixing application as being either FLOW CONTROLLED or special prior to purchasing a mixer.
The good news is that we design mixers that span at least 98% of all these mixing applications, which means that you don't need to pay for the promotion, marketing and overheads of the price leaders. A simple 10 to 15 minute conversation with a mixing specialist will generally define what type of mixer you require.
