Which is the most usual profile of a buyer of mills? It is a transformer —that needs triturar his defective pieces—, is a reciclador...?
The usual profile of the buyer of mills was a reciclador that bought defective materials, clean or contaminated to distinct transformers or to recogedores of wastes. Afterwards it sold the granza recovered in distinct markets. Later, the reciclador needed to specialise so much in materials of collected and his selection as in available sectors of his granza recovered, as like this it optimised economically his resources. Afterwards, the recicladores preferred to recover the clean material, postproduction of his customers without hardly contaminate, and gave it back to him to them same once recycled. Work to maquila. This situation has woken up the need of the majority of the transformers to select his defective product without contaminating neither mix, to integrate it on line directly to the production looking for the aim of waste zero, by what increasingly, the users of the mills are transformative turned into autorecicladores skilled. They require for this every time but specific mills for the restricted variety of his products. When being treated like a problem more than as a business, this customer prefers efficiency, but does not go in in details of quality.
Which is the most valued characteristic by the buyers in a mill?
For the reciclador, the robustness, since it realises moliendas of a wide variety of materials. Whereas the transformer prevails the efficiency, since it looks for the minimisation of the wastes of his plant. It appreciates also the little volume of the team and the absence of noise.
A priori, it seems that the mills are a type of team with little technology. It is this true? What has to guarantee a technologically advanced mill?
Is not true. A mill is technologically advanced if it adapts to the specific needs of the product to triturar and to the process that afterwards have to derive: then it differs in his geometry, in the power of the engine, in the type of rotor, the refrigeracion of rotor and of blades in case and in the profile of the camera of cut, ergonomics, form of feeding, if it works under water, if only densifica, and in the rapidity and ease of cleaning and of change of blades. They are important also the accessories, like way of capture of the product, of feeding and of download. The differences, although subtle, do not escape to an expert, but confuse to many possible users and buyers.
