In Doha/Qatar, Aquaseal produces dry mortar products for all phases of construction, from foundations to finishes, under the product brand name Durabuild. Aquaseal’s broad product program includes adhesives, sealants and grouts; damp-proofing and water proofing protection; curing and release agents; flooring systems; coating; roof sealants and products for concrete repair and protection. Of critical importance for the quality of these materials is the mixing technology used, with the mixer being the core component of a dry mortar production plant.
Aquaseal chose Eirich for the mixing and systems technology for the expansion of its production. Eirich can call on many years of experience when it comes to dry mortar systems with the equipment of more than 260 dry mortar plants. Following provision of details of the formulas and the required production quantities from Aquaseal, the complete system design and order handling was undertaken by Eirich. The detailed engineering and the delivery encompassed silos, steel structures, conveying, feeding, weighing and mixing systems and the control systems. The new plant, which commenced operations in autumn 2017, features a RV12 mixer (400 l size). With batch cycle times of 2-3 min and two-shift operations, this enbles an annual production output of approx. 50000 t.
The power input into the mix can be specifically adjusted to the product. Optimum mixing and dispersing effects are achieved without choppers. With sizes from 1 to 3000 l, just a single rotating tool is needed, so upscaling is simple. With an Eirich mixer there is no demixing so that all the formulas have the same mixing times.
