Feeding device GD Hammer Mill Process The feeding device above the hammer mill provides a dosed supply of raw materials to the grinding chamber of the hammer mill. At the same time, possible solid foreign objects are separated from these raw materials. By removing metal, stones and other heavy parts from the raw materials, the chances of explosions (caused by sparks) in the hammer mills grinding chamber is minimized. The lifetime of the screens is extended extensively since the chances of screen damages are reduced by removing these foreign part from the raw materials. Two types of feeding devices can be applied to the GD hammer mills: • Type HM GD: standard feeding device with automatic ferro parts separation • Type HM GD HPS: feeding device with automatic ferro parts separation and heavy parts separator Depending on the system configuration of the hammer mill (HM), both types of feeding devices can be applied to the HM 700 GD and the HM 1400 GD. The feeding devices can be used in combination with the optional automatic screen exchange. Benefits and Features High capacity ▶ Feeding devices with frequency controlled dosing roller, for optimized feeding speed of the various raw materials, up to 100 ton/hour Energy efficiency ▶ Energy efficient motors, which comply with the latest European regulations Low maintenance costs ▶ Automatic cleaning of the integrated magnet and automatic removal of collected heavy parts ▶ A longer life time of screens, due to capturing and removal of metal, stones and heavy parts High automation level ▶ Automatic load-dependent control of the dosing roller, contributes to optimal hammer mill operations ▶ Completely automatic cleaning of the magnet and removal of collected heavy parts Design ▶ Durable and robust design due to use of high-quality materials ▶ The hammer mill including the feeding device machine layout is flexible to meet the customers requirements and thus configurable to a left or right hand version. Easy and safe operation ▶ Easy accessible for maintenance ▶ Provision for mechanical blockage of the magnet during maintenance activities ▶ In conformity with CE and ATEX directives Datasheet V005 No rights can be claimed, based on the information in this document.

Comparison feeding devices for hammer mill 700/1400 GD Van Aarsen GD hammer mill is standard fitted with a feeding device type HM GD. Optional, the GD hammer mill can be equiped with the feeding device type HM GD HPS (including heavy parts separator). Benefits feeding device type HM GD HPS compared to the feeding device type HM GD ▶ The feeding device type HM GD HPS removes both ferro and heavy non-ferro parts from the raw materials (stainless steel, stones) ▶ By removing heavy parts from the raw material: • The risk of screen breakage and damage is significantly smaller. This will extend...
