In America including North and South America countries, there are many customers prefer using to mix dry mortar product. However, it has some disadvantages of as below:
A. Mixing Speed:
Almost 90% dry mortar product line is automatic system which requires short batch time and hope to finish more batches as many as possible. Due to is a kind of mild mixing one, the batch time is around 5-8 mins in general. Through Vortex Mixing Technology analysis, we design paddles to replace ribbon because the mixing action is more fast and strong. The paddle can be replacable easily and could be high wear resistance. According to our experience, one twin shafts paddle mixer can finish one batch mixing within 3 mins and discharge within 1 min.
B. Wear Resistance:
The material of ribbon is not hard enough to mixing sand. Generally speaking, the life of ribbon shaft is around 2 years but paddles can be used for more than 3 years. 2Cr13 is a kind of very high wear resistance material like Hardox used for paddles. Furthermore, the paddles can be replaced if broken but ribbon is hard to change in the future.
Vortex Mixing Technology develop pneumatic bomb-bay discharge valve which can fully unload finished product fast within 1 min according to flow ability of product but is slow speed to discharge. Furthermore, there will be little residues inside paddle mixer because the size of bomb-bay valve is much bigger than ordinary valve.
