Volumetric feeding The principal of volumetric feeding is accomplished by simply relying on the volumetric properties of the feeder to deliver product at a constant rate. For example, if a known Figure 1: A typical loss in weight feeder complete with electronic controller. Hopkins 18/9/06 12:16 pm Page 1

Loss in Weight Feeding
The Rospen lossinweight belt feeder is ideal for the efficient feeding of fragile and friable products such as fruit and cereal flakes. Its principle of operation is the same as the screw and tray options whereby the feeder and hopper are both mounted onto a Rospen low profile weigh platform. BELT FEEDER

Specifiion for the Manufacture of Concrete Poles
All cement shall be stored in silos or suitable weatherproof buildings so as to protect the cement from dampness and other causes of injury. Cement in bags shall be arranged in orderly stacks so that it can be easily inspected and shall be used in order of delivery. All cement used must be thoroughly dry and free from lumps, caking and watermarks.
BATCHING AND MIXING
Cement weigh hoppers must have an access port to facilitate inspection of the interior. The installation of the dust seal between the storage bin and the weighing hopper must not affect the we ighi ng accuracy. The weigh hopper shall have a coned bottom and a vibrator to ensure com plete discharge.
Dosing of raw coal with rotor weighfeeder Pfister® TRWK ...
· Development. The project included the replacement of the old raw coal feeding equipment to the mill, which consisted of an apron feeder, for the new design of rotor weighfeeder Pfister® TRWK. Rotor weighfeeder Pfister® TRWK installed in Carboneras is the first reference installation of raw coal and pet coke mill feeding in the cement industry.
