Material containers - Import export

Garland roller sets are used in belt conveyors that have to handle blunt, bulky, heavy materials. The increased containment capacity of the roller basin facilitates higher speed of transport than those of traditional stations. For upper stations in current use installations, garland sets with 3 and 5 rubberised impact rollers are mounted; for lower stations, garland sets with 2 rollers with scraping rubber rings are mounted.

Garland roller sets are used in belt conveyors that have to handle blunt, bulky, heavy materials. The increased containment capacity of the roller basin facilitates higher speed of transport than those of traditional stations. For upper stations in current use installations, garland sets with 3 and 5 steel or rubberised impact rollers are mounted; for lower stations, garland sets with 2 steel rollers or with scraping rubber rings are mounted. The flexibility of garland sets enables their adaptation to the material to be transported, facilitates transportation, reduces impacts on the rollers, and limits any lateral slipping of the rubber matting. The diagrams and Table 90 show the shapes of mountings of garland sets envisaged in TECNORULLI’s production programme. Other shapes may be considered on request.

The machine accurately doses gold and silver grains for the prodcution of bullions and cast bars. The Preci-dos is completely automatic, with dosing cells and grains transfers completely controlled by PLC. It has a number of steps to achieve accurate control on final weight. The grains container in the machine are loaded by gravity into the pre-dosing scale, to approach the final desired weight. After the pre-dosing step, a second phase starts to reach the final desired weight by adding a controlled quantity of gold or silver wire or powder (depending on customer specification) and the discharge the correct quantity of material into a container. To maintain accuracy and productivity, the machine is capable of self-learning, based on the continuous use. In particular the machine can statistically anticipate the average drop time of a single grain, to avoid overshoot.
