This means that not only the feeding and mixing process must be accelerated, but also that the discharge must happen quickly and without residues.
Powder mixing companies want to produce ideal mixing qualities. This should take place by fulfilling important secondary requirements:
The spiral mixing tool gently conveys the mixing goods upwards. This takes place on the periphery of the mixing chamber. In the center of the mixing chamber, the downward flow prevails. The conical closing element directs the flow back outwards. Different rotation speeds overlay the entire volume of the mixing chamber. Each particle is randomly in the upward movement or in the downward movement.
Conical valves have been used in the bulk solids industry for many decades. They are only installed vertically and have the advantage of optionally discharging mixing goods either rapidly or in a dosing mode. Their use within a precision powder mixer is a novelty. The cone in this case has particularly steep and smooth slopes. Gravity causes the mixing goods to slide downwards. This is how they are guided to the periphery. The mixing good flows into the operating range of the mixing tool and is conveyed upwards again and again. Theoretically, the mixing spiral has completely conveyed the entire mixing chamber volume upward after approximately 5 revolutions. This is the explanation for the extremely short mixing time.
This powder mixing
machine is called KoneSlid® mixer and combines excellent features:
For example, with this small KoneSlid® mixer of size KS 500 (500 litres usable capacity), it is possible to supply a filling / packing machine with a sufficient amount of mixed material. The maximum filling volume flow here is, for example, 10 m³ of baby food per hour.
Optionally, the mix can be inerted inside the mixer. Vacuum application and evacuation of ambient air from the mixing chamber then extends the batch time.
If required, you are welcome to use our technical centre in Paderborn. KoneSlid® mixers are available there in various sizes for tests with your mixing materials.
