Apron Feeder
FMS Apron Feeders offer a wide range of applications for various feeding, unloading and discharging objectives. These Apron Feeders are particularly well adapted to provide solutions for the conveying of moist and sticky bulk materials, such as clay, gypsum, anhydrite and pozzolana among others, as the slightly arched plates of the Apron Feeder allow cohesive materials to be scraped off easily.
The conveyors are equipped with forged chains and wear-resistant components. The plate, chain and roller design is configured to suit the specific task and the required conveying capacity. The machines are completely assembled and test run on FMS premises, and transported as a pre-constructed unit to site for easy installation and fast commissioning
Functions and characteristics
Length up to 50 m
Tailor-made machines with a large range of sizes and parameters
Variable speed drive for metering
Apron Feeder Special options: Lump breaker
For breaking up and homogenisation of accumulated material (necessary for on-going weighing and metering)
Spillage conveyor for containment of fines can be designed as a scraper chain or as a belt conveyor
Integrated material guides ensure controlled material flow and accurate distance between the hopper structure and apron surface
Depending on material properties, guides are equipped with adequately wear-resistant linings

Apron Weigh Feeder
Combines material extraction from hopper with weighing and metering in one machine, for applications where use of a belt weigh feeder is not possible.
Suitable for high temperatures (up to 400°C)
Suitable for abrasive material
Plate widths up to 1,800 mm allow installation of the feeder under silos containing sticky material, and extraction of material in a wide flow
Various weight measuring solutions available, depending on material, structure, and how the material is received into the feeder (extraction from hopper, intake direct from tipper, etc.)
Full pre-assembly and calibration are carried out on FMS premises
