Agitation. Mixing - Technical and economic aspects

Like all capital goods, the economic balance of an agitator requires an evaluation of its cost:

• investment ;

• depreciation of the amount invested ;

• operating costs (labor, energy) ;

• maintenance (labor, parts).

It seems out of place to mention the cost of equipment depreciation, as well as the labor involved in operating costs. In fact, both are linked to the value of the products processed, the type of operation carried out (storage, synthesis...), the added value due to the operation (synthesis...), the process used (stepwise, continuous...).

This study is therefore focused on evaluating the cost of building an agitator, the cost of the energy used and the cost of maintenance.
