Zerma offers a complete program of suction systems to discharge material from the machines. These systems include blowers, piping, cyclones, rotary valves and bag filling stations. Additionally, we offer separation equipment to remove dust and fines from the material flow. All blower systems can be equipped with components manufactured from highly wear resistant steels for use in abrasive applications, and insulated with noise absorbing materials.
Zerma offers a large variety of conveyor belts, either as feeding belts for shredders and granulators, or as discharge belts to move material from the first step of shredding to a granulator in a two-step recycling process. All belts are built very sturdy and feature standard options such as a corrugated side-walls, further they can be equipped with a metal or magnetic free zone for the installation of a metal detector of cross belt magnet. An alternative to a conveyor belt is to discharge material from the machine by means of a Zerma screw auger.
To increase the throughput of the Zerma GSH series granulators when used with loose materials such as bottles, we developed the force-feeding system that forces the input material into the cutting chamber and avoids the common problem of material ‘dancing’ on the rotor. Adding one of our force-feed devices greatly increases the machine throughput. The force feeders are available in two basic designs; screw and paddle type.
Metal detectors and separators
In order to produce the best quality output material it is important to ensure the material is free from contamination, such as metal. Zerma offers a wide range of products to detect and remove various kinds of metal contamination. This ranges from magnets used to separate ferrous metals to all-metal detectors and separators to detect and separate all kinds of metal contaminants from the material stream.
It is always important to achieve a well defined output size. Zerma offers a range of screening solutions for different materials and throughputs. Due to its small size the Zerma rotary screening machine is well suited to be integrated with PM series pulverisers, especially in roto-moulding applications. The conventional horizontal screening machines offer a higher throughput and the possibility to classify different material sizes.
