21. Metal Rain & Wind Cover Belt Conveyor
Corrugated, Modular/Segmented, Galvanized
Metal conveyor covers are the perfect solution
to protect the material from rain and wind and
to protect the environment from noise and
dust.
Metal covers are made of galvanized steel
thickness of 0,75mm; they are self-standing,
safe and very easy to assembly and
disassembly. They do not require any
maintenance and can be mounted on any
conveyor with belt width from 400 to
1800mm.
The biggest advantage is that they can be open
on both sides, and for complete removal
require only one person

26 Previously, the only method to seal conveyor transfer points was to place rubber along the chute wall to act as a containment device. Tremendous pressures are created in the load zone by the conveyed product. These pressures act on the rubber seal forcing material from the containment system. While rubber is an excellent dust seal, it does a very poor job of containing large amounts of material.
13 The easiest way to define proper belt support, is to define improper belt support. Improper belt support is when the belt itself moves away from the normal belt line, allowing a gap between the rubber skirting and the belt. This is when the problem of skirt spillage starts. As the material travels along the belt, it can take several paths. As the belt moves down from the normal belt line, material becomes entrapped between the rubber skirting and the belt. This entrapped material will migrate along the belt until it reaches an idler. Tremendous forces are created at this entrapment point. the material will either cause grooving of the belt, scalloping of the skirting, fall to the outside area of the load zone, or travel down the belt as desired. Three of the four situations described are undesirable.
