Iron removal feeding machine

Product positioning:The core pre-treatment equipment in the front-end process of the crushing and washing production line integrates automated feeding and efficient iron removal functions. It is a key piece of equipment to ensure the safety of subsequent equipment and improve the purity of the finished product.

I. Core Functions and Importance

In the process of recycling waste plastics, raw materials (such as waste films, bottle bricks, and appliance casings) often contain metallic impurities such as nuts, screws, wires, and iron filings. If these ferromagnetic impurities enter subsequent processes...Crusher, friction cleaner, hot melt extruderEquipment such as these will cause:

1. Severe wear or breakage of cutting toolsThis significantly increases maintenance costs and downtime.

2. Damaged screen, screw and cylinderThis can lead to permanent damage to the equipment.

3. Pollution of final plastic particlesThis reduces product quality and value.

4. It may cause sparks and pose a safety hazard.。

Iron removal feeding machinepass"Feeding + Magnetic Separation"The integrated design continuously and automatically removes most ferromagnetic impurities before the material enters the main crusher, ensuring the quality of the entire production line."Safe, efficient and stable operationIt provides the first and crucial layer of protection.

II. Main Structure and Working Principle

1. Structural composition:

• Feeding section:

  • hopper:The large hopper allows for manual or conveyor belt feeding.

  • Lifting Conveying Mechanism:Commonly usedInclined belt conveyor(Equipped with a non-slip, wear-resistant belt) orChain conveyorThe material is lifted from a low position to the feed inlet of the crusher.

• Iron removal section:

  • High-power permanent magnet drum/magnetic separator drum:The core component of the equipment. Installed at the end (inside) of the conveyor belt, it rotates at the same speed as the belt. The roller uses...High-performance neodymium iron boron permanent magnet materialsThis generates a high-intensity deep magnetic field.

  • Automatic separation device:Iron impurities adsorbed on the magnetic drum will automatically fall into the magnetic field as the drum rotates until it leaves the magnetic zone, under the influence of gravity or a scraper.Iron collection box/iron discharge portThis achieves separation from the material.

• Drive and control systems:

  • Motors and speed reducers:Provides smooth power for the conveyor and magnetic roller.

  • Control box:It can be integrated with frequency converter speed regulation to control the feeding speed and link with the whole production line.

2. Workflow:
Raw materials are fed into the hopper → an inclined conveyor belt lifts them evenly → as the material passes the end magnetic separator drum → iron is firmly adsorbed onto the surface of the drum below the belt →Cleaning plasticThe iron continues to fall parabolically into the crusher feed inlet → as the drum rotates to the non-magnetic zone, it automatically falls off and is collected.

III. Core Features and Advantages of the Product

• Highly efficient and powerful iron removal:Utilizing high-performance permanent magnets with high magnetic field strength and large gradient, it can remove deep-seated and loosely encapsulated iron impurities, typically achieving an iron removal efficiency of up to [percentage missing].Over 98%。

• Integrated intelligent design:One machine can solve both the feeding and iron removal needs at the same time, saving space, reducing investment costs, and simplifying the operation process.

• Fully automated continuous operation:The entire process of feeding, conveying, removing iron, and discharging iron is completed automatically without human intervention, greatly improving production efficiency.

• Protect core equipment:It forms a "firewall" for downstream crushers, washing machines, granulators, etc., significantly reducing equipment wear and maintenance frequency.

• Rugged and durable design:The frame is sturdy, the belt is designed to prevent deviation, and the magnetic roller is designed to prevent shock and demagnetization, making it suitable for the harsh working conditions of the recycling workshop.

• Safe and reliable:Eliminate safety risks such as sparks and jamming that may be caused by metal entering the equipment.

• Easy to maintain:The iron collection box is easy to clean, the magnetic roller is maintenance-free, and the overall structure is easy to clean.

• Powertrain configuration:Speed-regulating motor, power approximately 4-7.5kW

• Applicable materials:Waste PET bottle flakes, HDPE/PP crushed materials, film clumps, and fragments of household appliance casings, etc.

V. Installation location in the crushing and washing line

Typical installation location:[Feeding Section] → [Iron Removal Feeder] → [Main Crusher] → [Pre-washing Tank/Friction Cleaner] → ...Subsequent Processes

Best practice recommendations:For raw materials with a particularly high amount of iron impurities (such as car bumpers and discarded household appliances), this can be done in the production line.Multiple iron removal stages are installed.For example, an additional iron remover (such as a suspended iron remover or a drum magnetic separator) can be installed after coarse crushing and before fine crushing to form multiple protections.
