Feeders are used to control and meter the flow of materials to meet the specified flow rate of the crushing system or process system. They are the first step in designing a crushing circuit or processing system to meet the specifications required.
Applications

Several types of feeders can be used in a crushing/process system. They are selected to suit the material, feed rates and pre-sorting. The feeder decides the magnitude of the load on the crushing/process system. Therefore, the handling system load condition and thereby its performance is controlled by the feeder.
McLanahan offers a wide range of feeders and is about to fill almost all applications either by a standard feeder or a custom feeder. Our feeders have a long history in a whole range of applications, including ores and minerals in the mining industry; gravel, sand, limestone and granite in the aggregate industry; and municipal waste, shredded cars and metal, dross, slag, wood and stumps in the recycling industry. Between standard and custom offerings, McLanahan has a feeder to suit your requirements.
The Apron Feeder is the most robust feeder and provides a high ROI. It offers a long service life with low maintenance and can be tailored to your application or installation.
Apron Feeders are used for:
Drag and Reclaim Feeders consist of strands of chain with connecting cross bars designed to pull material. The design offers a low profile in the feed area, allowing it to be filled easier by bulldozers.
Drag and Reclaim Feeders are used for:
Materials are conveyed along the pan of the feeder as a result of the vibrating motion imparted to the particles. This vibration pre-sorts the material passing the fines to the bottom. The fines can then be pre-screened before a crusher, thus reducing the required capacity and wear.
Vibrating Grizzly Feeders are smaller in size than Apron Feeders. They are used for:
Materials are conveyed along the feeder as a result of the rotating motion of the elliptical bars. This motion scrubs and pre-sorts the material passing the fines to the bottom. The fines can then be pre-screened before a crusher, thus reducing the required capacity and wear.
Wobbler Feeders are used for:
The following information should be taken into account when choosing a feeder:
