4 Pipes, Launders and Chutes in an Iron Ore Mining Project [Pg.38]

This relates to drum filters, designed by Eimco, in the USA. These filters are used in illmenite beneficiation and titanium dioxide plants. The filters, including parts like agitators and troughs are lined with a semi-hard flexible ebonite of natural rubber to protect the equipment against the abrasive action of the ore and solid particles in the slurries. [Pg.38]

The anti-abrasive or anti-corrosive rubber linings are applied to the metal surface by adopting different kinds of bonding systems such as ebonite bonding, chemical adhesive bonding or self-vulcanising cement bonding. [Pg.39]

In the self-vulcanising cement bonding method, precured soft rubber sheet is bonded to the metal by a cement which cures at ambient temperature thereby effecting the required bond strength between the soft rubber and the metal. This technique is known as the cold bonding technique. [Pg.39]

In all of the above cases, the metal surface is to be sandblasted to provide a whitish rough finish which will ensure good anchoring of the adhesive between the metal and the rubber. [Pg.39]
