Technical Data
Technical specifications
Listed values apply to the identified configuration. Confirm material conditions, utilities and optional equipment before selection.
| Belt width (mm) | Production capacity (kg/h) | Belt / distributor drive power (kW) | Overall length (m) | Reference weight (kg) |
|---|---|---|---|---|
| 600 | 100–400 | 1.5 / 2.2 | 18.2 | 1,500–3,000 |
| 1000 | 200–800 | 5.5 / 2.2 | 18.2 | 2,700–6,000 |
| 1200 | 300–1000 | 5.5 / 2.2 | 18.2 | 3,000–7,000 |
| 1500 | 500–1200 | 5.5 / 2.2 | 18.2 | 4,000–9,000 |
Production capacity depends on the actual material properties. Product particle size is engineered to the customer’s requirements. Final specifications are subject to process testing and engineering confirmation.
Applications
Rotary Steel-Belt Melt Condensation Granulator: industrial applications
Applications include waxes, resins and bitumen and industrial chemicals. Confirm material properties and process conditions before selecting the equipment configuration.
Industrial chemicals
Sodium sulfide, maleic anhydride, stearic-acid products, hot-melt adhesives and compatible additives.
Rubber and plastics additives
Rubber auxiliaries, plastic additives, antioxidants and anti-aging agents.
Light stabilizers
Compatible light stabilizers, including types 622 and 944, subject to process verification.
Applicable thermal range
Materials requiring condensation granulation with a melting or softening point of 250 °C or below.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Molten-feed delivery
Hot molten material is transferred from the upstream process to the distributor.
Controlled distribution
The distributor applies the melt to the steel belt by intermittent dripping, continuous strip extrusion or full-width overflow.
Steel-belt conveying
The stainless-steel belt carries the distributed material through the cooling zone at a controlled speed.
Continuous spray cooling
Cooling water sprayed beneath the belt removes heat without direct contact with the product.
Solidification and forming
The melt cools and solidifies into hemispherical granules, strips or flakes according to the selected distribution mode.
Finished-product discharge
The solidified product separates from the belt at the discharge end for collection or downstream handling.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
ISO 9001-controlled manufacture
The equipment is designed and manufactured under an ISO 9001-certified quality-management system stated to be applied to military-equipment production.
Configurable stainless-steel belt
The hard, smooth belt provides high thermal conductivity and resistance to high and low temperatures; its length, width, thickness and surface finish can be selected for the duty.
Stable continuous production
Smooth, low-noise continuous operation supports high production efficiency and consistent product formation.
Uniform formed product
Controlled distribution and belt movement help produce regular, uniform and relatively small particles.
Recirculating cooling water
Cooling-water reuse helps reduce water consumption, limit dust and improve the production environment.
Variable-speed process control
Frequency-controlled distributor and belt drives allow operating speed to be matched to material properties.
Three distribution modes
Intermittent dripping, continuous strip extrusion and full-width overflow produce hemispherical granules, strips and flakes respectively.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Molten-feed interface
Receives hot melt continuously from the upstream process.
Configurable distributor
Supports intermittent dripping, continuous strip extrusion or full-width overflow.
Stainless-steel belt
Provides a hard, smooth heat-transfer surface with selectable length, width, thickness and finish.
Spray-cooling system
Continuously cools the underside of the belt while keeping cooling water separate from the product.
Cooling-water circulation
Allows process water to be recirculated to reduce consumption and support a cleaner operating environment.
Variable-frequency drives
Independently regulate distributor and belt speeds for process adjustment.
Product discharge section
Releases the solidified granules, strips or flakes for collection.
