Lvlon is a machinery manufacturer in Henan, China, building the 4TPH coconut shell pellet plant for coconut processors and large biomass fuel plants across Southeast Asia and tropical regions-Indonesia, the Philippines, Vietnam and beyond. As the factory, we supply wholesalers, bulk buyers, distributors and agents directly-no middle layer. In-house fabrication of every stage. One supplier, one warranty. OEM/ODM on die size and configuration, with your brand or specification. Spare parts stocked and air-freighted in 5–15 days.
The Shell That Needs No Preparation
Coconut shell is already a shell. It needs no debarking and no chipping-skipping two stages that every other biomass line requires. The shell goes directly into the hammer mill. The 500kg/h coconut line uses an airflow dryer and a single mill; this 4 t/h line scales the same concept to industrial volume: bigger dryer, four mills, eight times the throughput.
Five Stages, Scaled Up
| Stage | Equipment | Key spec | Power | Rating |
|---|---|---|---|---|
| Crushing | HM800 hammer mill | <5 mm output | 45 kW | 2–3 t/h |
| Drying | GX2200 drum dryer | Ø2.2m×20m | 30+55+2.2 kW | 4–5 t/h |
| Pelletizing | MZLH420 ring die mill ×4 | die Ø420mm, 2 rollers Ø165mm | 90×4 kW | 1 t/h each |
| Cooling | SKLN2.5 counterflow cooler | 2.5 m³ | 1.1+1.1 kW | 5 t/h, 6–10 min |
| Packing | WDCS-50 packer | auto weighing & sewing | 2.2 kW | 3–4 bags/min, 5–50 kg |
The GX2200 dryer is the largest in the pellet plant range: 2.2 meters diameter, 20 meters long, 55 kW induced-draft fan-the thermal capacity to pull coconut shell from incoming moisture to the 10–17% forming window at 4–5 tonnes per hour. Below 10%, the die resists. Above 17%, the pellets crack. The dryer holds the window.
The four MZLH420 mills run in parallel-each at 1 t/h, each with gear drive that delivers 20% more output than belt drive. The four-mill array means one mill can be serviced while three continue producing: the line drops from 4 t/h to 3 t/h instead of to zero. Each mill is fitted with overload safety pins (shear protection), variable-frequency feeders, serpentine-spring couplings for shock absorption, and imported bearings and seals-the components that keep the mill running through the 300 working days of an industrial production schedule.
The SKLN2.5 cooler handles 5 t/h-ahead of the 4 t/h pelleting capacity, so the cooling stage never becomes the bottleneck. Pellets exit the die at over 80°C and higher moisture; the cooler brings them to 3–5°C above ambient and cuts moisture by about 5%, preventing the mold and crumbling that happen when hot pellets are bagged.
FAQ
Q: Why no debarking and no chipping?
Coconut shell is already shell-it needs no debarking and no chipping. The shell goes directly into the hammer mill. Two stages saved: investment, floor space, power.
Q: 4 t/h coconut line or 500 kg/h line?
500 kg/h: small entry line-airflow dryer, single mill (ring or flat die), for small coconut processors. 4 t/h: industrial scale-GX2200 drum dryer (Ø2.2m×20m), four MZLH420 mills with gear drive, for coconut-producing regions and large pellet plants. Eight times the capacity, industrial-grade equipment. The decision is: how many tonnes of coconut shell per day?
Q: What if one of the four mills goes down?
The line keeps running. Three mills continue producing at 3 t/h. Overload safety pins protect the equipment-the pin shears before the mill is damaged, and the pin is replaced in minutes.
