In polymerization plants for synthetic rubbers, it is necessary to use granulators to break the rubber crumbs and stabilize the material flow in section of process as drying or weighing and bales packaging.
PREVIERO is a company that has been led by the Previero family for the past 3 generations. At the beginning of the 1920s, Previero Natale moved his business as a sales representative from Switzerland to Como. Here he started a new business activity dealing with the selling and reparation of textile industry and woods machines. A few years later, he began a construction project of machines designed and manufactured entirely in Italy.
Previero offers a complete range of machinery for the grinding of plastic, natural rubber, and synthetic rubber and recycling plants for the treatment of materials such as copper wires, tires and post-consumer packaging.
In polymerization plants for synthetic rubbers, it is necessary to use granulators to break the rubber crumbs and stabilize the material flow in section of process as drying or weighing and bales packaging.
The technology of continuous mixing is growing rapidly both for the production of rubber compounds and for polymeric alloys. Plants are available for many applications and capacities.
The natural and synthetic rubber bales are prepared and placed on the storage belt. The size of the ground material can vary according to the requirements and either single or two-stage grinding may be adopted.
The bands of rubber compound coming in line from the batch-off or from off-line pallets are introduced into a cube-dicer to be cut to the desired dimension.
The plant is able to directly grind standard 25-35 kg bales of synthetic rubber and110 kg bales of natural rubber. During the grinding process, liquid or powder form anti-sticking material can be automatically dosed.
The standard shaped bales of synthetic rubber and thermoplastics are placed on a feeding belt to be transported to an automatically fed granulator.
