FAQ

Fleming’s plastic recycling solutions can handle a wide range of plastic materials, including:

• PET (Polyethylene Terephthalate): Used in beverage bottles, food containers, and synthetic fibres. Lightweight, strong, and highly recyclable.
• HDPE (High-Density Polyethylene): Found in milk jugs, detergent bottles, and plastic piping. Durable, impact-resistant, and widely recycled.
• LDPE (Low-Density Polyethylene): Common in plastic bags, shrink wrap, and flexible tubing. Soft, flexible, and moisture-resistant but less commonly recycled.
• PP (Polypropylene): Used in food containers, bottle caps, and automotive parts. Heat-resistant and chemically resistant.
• PS (Polystyrene): Found in foam packaging, disposable cups, and insulation. Available in rigid or foam form but challenging to recycle.
• ABS (Acrylonitrile Butadiene Styrene): Used in LEGO bricks, electronics housings, and automotive components. Tough, impact-resistant, and durable.

These systems efficiently process production scrap, rejected parts, and post-consumer waste, turning them into high-quality regrind or pellets for reuse in manufacturing.

Granulators are designed for size reduction of plastic parts, producing uniform regrind suitable for direct reuse in injection moulding or extrusion. Shredders, on the other hand, are used for bulkier or tougher plastic waste, breaking down large items into smaller, manageable pieces before further processing. Depending on the application, a combination of shredding and granulation may be required for optimal recycling efficiency.

Energy-efficient plastic recycling machines incorporate low-energy motors, advanced rotor designs for optimised cutting performance, and automated load sensing to adjust power consumption based on material flow. Additionally, smart control systems help reduce idle time and improve overall process efficiency, minimising both energy costs and environmental impact.

There are 3 basic cases of heating and cooling:

1. Heating to production temperature: The unit heats only.
2. Production: Due to changes in the ambient temperature, cycle time, etc., the temperature of the consumer also changes. If it rises, the unit will cool; if it drops, the unit will heat.
3. Production interruption: Generally, the consumer must be heated to prevent its temperature from dropping.

Method: Heating and cooling take place in on/off mode, i.e. either completely on or completely off. Due to its PD behaviour, the controller cycles, with heating or cooling pulses becoming shorter as the temperature nears its set point. Cycling prevents under and overshooting.

Because of the inertia of the control loop, on/off mode (cycling) provides the same control accuracy as control valves, for example, which are significantly more technically demanding and much more likely to break down. The controller is a three-step controller with the positions “heating – neutral – cooling”.

The minimum required accessories consist of the following:

• A temperature and pressure-resistant hose for the outlet and for the inlet.
• Two hoses for the cooling water circuit.
• Power cable.

Additional accessories depend on the application involved.

The theoretically lowest possible outlet temperature of a temperature control unit is the inlet temperature of the cooling water (for direct cooling). Practically speaking, however, the minimal outlet temperature must be at least 5°C higher.

The reason for this is that a minimal temperature drop is necessary in order for heat exchange to occur between the cooling water and the circulating heat transfer fluid in the temperature control circuit (consumer circuit).

As applications conditions have such a large influence (operating temperature, dusty environment, quality of the heat transfer fluid, dirt in the temperature control circuit (consumer, connection lines)), absolute answers aren’t possible.

Customers are encouraged to use their judgement to find an optimal cleaning interval. The Operating Instructions serve as a basis. In the “Maintenance/Service” section, you’ll find tips for necessary cleaning procedures/checks to be made on the temperature control unit.

DynaCon modular conveyors can be built in a variety of configurations using horizontal, vertical, and Z-style decline and incline modules. These systems support widths from 4″ to 72″ and lengths up to 100 feet, with options like flat conveyors, Z-style incline conveyors (30° to 90° angles), and overhead setups.

When choosing a process cooling system, key factors include the required cooling capacity (kW or tons), operating temperature range, heat load of the process, ambient conditions, and the type of cooling medium (air or water). Additionally, energy efficiency, system footprint, and maintenance requirements should be considered to ensure optimal performance and long-term cost savings.

Air-cooled chillers use ambient air to dissipate heat and are typically easier to install and maintain, making them ideal for locations with limited water supply. Water-cooled chillers, on the other hand, use a cooling tower or other water sources for heat dissipation, providing higher efficiency and better performance in hot climates or high-heat load applications. The choice depends on the specific cooling needs, site conditions, and energy efficiency goals.

To enhance energy efficiency, consider using variable-speed compressors, high-efficiency heat exchangers, and advanced control systems that adjust cooling output based on demand. Regular maintenance, such as cleaning coils, checking refrigerant levels, and optimising water flow rates, also ensures the system operates at peak efficiency. Additionally, integrating free cooling solutions or heat recovery systems can further reduce energy consumption and operating costs.

ULTRA Dryers use a unique vacuum drying technology that significantly reduces energy consumption. While the energy to heat raw material is similar across all drying processes, the energy to dry the material is where ULTRA excels. For a process running at 220 lb/h (100 kg/h), ULTRA Dryers use about 41 Watts/lb less than a generic desiccant dryer, saving approximately $6,500 annually. Features like Temperature Sense Control and no regeneration process further minimise energy use, making drying costs so low it’s almost free.

ULTRA Dryers require minimal maintenance due to their efficient design. Unlike desiccant dryers, there’s no regeneration process, no desiccant to replace, and no filters to clean. The compact heating hopper and single, smaller blower and heater mean fewer components to service. Plus, ULTRA Dryers come with a 5-year warranty, ensuring long-term reliability with virtually no scheduled maintenance needs.

ULTRA Dryers dry materials up to six times faster than conventional desiccant dryers by using vacuum technology instead of prolonged hot dry air exposure. For example, ABS heats in 15-30 minutes at 176°F (80°C), and PET in 40-60 minutes at 338°F (170°C), with vacuum drying taking just 20-30 minutes per cycle. This speed enables quicker start-ups, reduces production downtime, and increases overall productivity.
