Product Overview
This small swing granulator is a compact, high-performance machine designed for converting moist powders or dry block materials into uniform granules. At its core, a rotating roller with an adjustable sieve mesh mechanically forces material through the screen, yielding consistent particle sizes critical for downstream processes. The unit is engineered for ease of use: its open hopper and quick-release roller assembly simplify loading and cleaning, while the intuitive controls allow an operator with minimal training to achieve repeatable results.
The equipment is widely used in pharmaceutical, chemical, food, and related industries for granulation, crushing, and homogenizing tasks. Its stainless steel exterior and GMP-compliant design ensure product purity and ease of cleaning, while the enclosed gear mechanism provides quiet, stable operation. Whether you are preparing tablet press feed, reclaiming caked chemicals, or forming ceramic premix, this system adapts to diverse material characteristics. By selecting the appropriate mesh screen and adjusting roller pressure, users can produce granules from fine powders (0.5 mm) up to larger agglomerates (2 mm and above).
Built for continuous duty, this granulator offers robust construction and reliable performance under demanding conditions. The cast-iron gearbox, oil-bath lubrication, and rigid base frame minimize vibration and extend service intervals. All internal shafts and bearings are sized with generous safety factors, ensuring many years of trouble-free service. Its simple operation and low maintenance requirements make it a cost-effective solution for consistent material preparation. Even when handling abrasive or sticky materials, the durable stainless steel surfaces resist wear while the reversible roller helps clear blockages automatically, maintaining steady throughput.
Key Features
- Stainless Steel Roller & Contact Parts: The roller, hopper, and discharge surfaces are fabricated from high-grade stainless steel, preventing any reaction with product ingredients and avoiding metal contamination. This material choice also withstands frequent washdowns and chemical cleaning agents, making it ideal for GMP/GLP environments.
- Adjustable Sieve Mesh System: The machine accommodates easily interchangeable nylon or metal mesh screens, which are held in place by twin clamping tubes with a fine-tooth adjustment wheel. Operators can quickly set the desired mesh tension and swap screens to achieve granule sizes from 0.5 mm upward, meeting diverse formulation needs without tools.
- High-Efficiency Worm Gear Drive: A precision 1:30 worm gear reducer, continuously lubricated by an internal oil reservoir, delivers smooth, quiet power transmission from the motor to the roller. This design ensures minimal backlash and wear, providing decades of service with only periodic oil checks.
- Large-Volume Hopper: The rectangular inlet (260×300 mm) and steep walls allow easy manual feeding of sticky or free-flowing materials, while the generous capacity reduces the frequency of refilling during batch production.
- Reverse Roller Rotation: The roller automatically alternates direction at 50 rpm, preventing material from accumulating on one side of the screen, improving throughput uniformity, and extending mesh life.
- Rapid Disassembly for Cleaning: By loosening three captive screws, the front bearing housing and roller can be withdrawn, exposing all wetted parts for a thorough wipe-down or wash. This quick disassembly dramatically reduces changeover time between product runs.
- Robust Floor-Standing Design: The wide footprint and low center of gravity allow the machine to operate stably without bolting down, offering easy relocation between workstations or labs.
- Overload Protection & Safety: The drive system includes a slip-clutch mechanism to protect the motor and gears against jammed material, while fully enclosed moving parts meet CE safety guidelines.
- Versatile Power & Voltage Options: The motor can be supplied in 1.1 kW or 0.75 kW ratings, and the electrical system can be configured for 220V single-phase or 380V three-phase power, providing flexibility for labs and factories with different electrical infrastructure.
- Quiet Operation: The enclosed gearbox and balanced roller design keep operating noise to a minimum, allowing the machine to be used in noise-sensitive environments without causing disruption.
