The hoppers are located at the very beginning of the crushing plant. They are usually followed by a vibrating feeder and in some cases by a grizzly screen.
The hoppers are very important because they ensure the loading of all the materials to be crushed. The vibrating feeder, as its name suggests, transfers the loaded materials from the hopper either to the primary crusher or to a grizzly screen. The grizzly screen separates the fine materials in order to increase the efficiency of the crusher. As for the separated materials, they pass directly to the secondary crusher.
Boratas feeding machines are very sturdy, shockproof, and long lasting. These machines are also easily maintainable, so the operating costs are minimized and the production capacity remains high.
