Top 5 Compact Granulators with Dry Separators Suppliers in Asia [2025]

When it comes to sheer innovation in dry process equipment, GreenTech Recyclers out of Shanghai has been turning heads since 2010. What started as a small workshop focused on circuit board recycling equipment has grown into a global player, and their CGD-800 Compact Granulator is a big reason why. Designed specifically for mid-sized facilities, this machine packs a punch with a 500-1,200 kg/hour capacity—perfect for handling everything from circuit boards to plastic scraps.

The magic here is in the dual-stage process: first, a rugged single-shaft shredder tears materials into 2-5cm pieces, then a high-speed granulator breaks them down to 3-8mm granules. The real star, though, is the dry separator module. Using a combination of air classification and electrostatic separation, it can pull out 99% of metals from plastics in one pass—no water needed. "We used to spend hours sorting granules by hand," says Rajesh Patel, operations manager at a Mumbai-based e-waste plant. "With the CGD-800, we've cut labor costs by 40% and boosted metal recovery by 15%."

GreenTech doesn't skimp on durability either. The granulator's blades are made from nano-ceramic composite material (a tech they pioneered), which lasts 3x longer than standard steel blades. And for recyclers worried about downtime, their "QuickSwap" system lets you ｒｅｐｌａｃｅ worn parts in under 30 minutes. At around $85,000-$110,000, it's not the cheapest option, but users say the ROI comes within 18-24 months.

South Korea's EcoSphere Engineering has built its reputation on precision, and their EcoGran-DS 500 is a masterclass in detail. Launched in 2023, this compact granulator is tailor-made for small to medium recyclers who need reliability without the bulk. At just 3.2m x 1.8m x 2.1m, it fits through standard factory doors—something anyone who's struggled to move heavy machinery will appreciate.

Don't let the size fool you, though. The EcoGran-DS 500 handles 300-800 kg/hour and uses a unique "vibratory dry separator" that's gentler on fragile materials like circuit board components. Instead of blowing air wildly, it shakes granules across a sloped screen while applying static charge, so even tiny metal fragments (down to 0.5mm) stick to collection plates. "We work with a lot of old CRT monitors, and the glass is super brittle," explains Kim Ji-hyun, owner of a Seoul recycling co-op. "Other machines would crush the glass into dust, but EcoSphere's vibratory system keeps granules intact, so we can separate leaded glass from plastic frames easily."

EcoSphere also wins points for smart tech. The machine connects to a mobile app that tracks performance metrics—like granule size consistency and separation efficiency—and sends alerts if something's off. It's a game-changer for remote monitoring, especially for facilities with limited staff. Priced at $65,000-$90,000, it's a solid mid-range pick, and with a 3-year warranty (one of the longest in the industry), you're covered if anything goes wrong.

Japan's TechnoCycle has been a household name in recycling machinery since 1992, and their TC-DryGran 1000 lives up to the hype. Known for bulletproof build quality, this granulator is designed for heavy-duty, 24/7 operation—ideal for large facilities processing 800-2,000 kg/hour. If you're dealing with tough materials like aluminum cans, copper wiring, or even small metal scraps, this is the workhorse you want.

What sets the TC-DryGran apart is its triple air classification system . Most dry separators use one or two air streams, but TechnoCycle's design adds a third "fine-tuning" stage that sifts out micro-sized particles (think 0.1mm metal dust) that other machines miss. This is a big deal for recyclers selling to smelters, where purity is everything. "Smelters pay a premium for 99.5% pure copper granules," says Takeshi Tanaka, who runs a Tokyo-based metal recycling plant. "TechnoCycle's machine gets us there consistently, which adds about $0.50 per kg to our profits."

Of course, all that power comes with a footprint—at 4.5m x 2.2m x 2.8m, you'll need space. And at $140,000-$180,000, it's the priciest option on this list. But for high-volume operations, the investment pays off. The machine's energy-efficient motor (rated at IE4) uses 20% less electricity than competitors, and TechnoCycle's legendary service team ensures 98% uptime. As Tanaka puts it: "It's like buying a Toyota Land Cruiser—you pay more upfront, but it runs forever."

Singapore's BioCircle Machinery may be the new kid on the block (founded in 2018), but they've made a splash with their BioDry 600 , a compact granulator built for sustainability. Targeting eco-conscious recyclers, this machine is all about reducing carbon footprints—without sacrificing performance. It starts with the frame: made from 30% recycled steel, and the motor is solar-ready, so you can plug into renewable energy sources.

Capacity-wise, it's in the sweet spot for small facilities: 200-600 kg/hour, perfect for plastic pneumatic conveying system setups or small-scale circuit board recycling. The dry separator uses a low-energy air blower and a rotating sieve to separate materials, cutting power usage by 35% compared to similar models. "We wanted to be zero-waste, so we needed a machine that didn't guzzle electricity," says Aisha Khan, owner of a Kuala Lumpur-based plastic recycling startup. "The BioDry 600 runs on our solar panels, and we've cut our monthly energy bill by $300."

BioCircle also gets points for user-friendliness. The control panel is touchscreen with pre-set modes for different materials (plastics, metals, e-waste), so even new operators can get up to speed in an hour. And at $55,000-$75,000, it's one of the most affordable options here. The tradeoff? It's not built for ultra-tough materials like thick aluminum or steel chunks. But for plastics, small electronics, and light metals, it's a solid, green choice.

Last but never least, Rhino Recycling Systems out of Ahmedabad has carved a niche with the RhinoDry 750 , a granulator built for the realities of emerging markets. Launched in 2015, this machine is designed to handle "dirty" materials—think circuit boards with residual solder, plastic scraps with dirt, or even small cables—without clogging up. For recyclers in countries where waste streams are less sorted, that's a lifesaver.

With a 400-1,000 kg/hour capacity, the RhinoDry 750 uses a robust 2-shaft shredder to break down tough materials, followed by a granulator with adjustable screen sizes (3-12mm) to customize granule output. The dry separator is simple but effective: a combination of gravity separation (heavier metals fall first) and air classification. It's not as high-tech as some competitors, but it's reliable—and easy to repair with locally available parts. "We had a bearing fail last year," says Anil Sharma, who runs a recycling facility in New Delhi. "Rhino sent a technician the next day, and we were back up in 4 hours. Try getting that from a European brand!"

Priced at $50,000-$70,000, it's the most budget-friendly option on this list, and Rhino offers flexible payment plans to help small businesses get started. The downside? It's a bit noisier than others (around 85dB, compared to GreenTech's 75dB), and separation efficiency tops out at 95%—still great, but not 99%. For recyclers prioritizing cost and local support, though, it's hard to beat.
