Mixer/blender for mixing sodium sulphate?

Mixer/blender for mixing sodium sulphate?

Mixer/blender for mixing sodium sulphate?

(OP)
We used a ordinary concrete mixer to blend a mixture sodium sulphate (95%) and some other chemicals (5%)in a humid environment.

Problem we encounter is rusting and corrosion of the mixer. The rust also conmainates the mixture. Now we are considering to build our own mixer, what material is suitable to build the mixer?

Our mechanical department is suggesting using stainless steel. From memory they are various type of stainless steel, should i find one with high cromium content?

Is it possible to coat the stainless steel with some material to avoid rusting and contamination?
