Homemade Biomass Pellet Plant - 1-2 tph DIY Wood Pellet Production Line
A homemade biomass pellet plant is the right answer when the raw material is already on the farm or in the workshop and the goal is to turn a disposal cost into a heating bill that drops by half.
Features
Mikim's 1 to 2 tph package is built around a single MZLH ring die mill sized for owner-operators: one trained worker per shift, a flat concrete floor, a three-phase electrical supply, and a willingness to spend one week on commissioning. It is not the cheapest line on the market and it is not the most automated. It is the line that an experienced woodworker can run on day 14 without phoning the factory.
What Is a Homemade Biomass Pellet Plant?
In our catalogues a homemade plant is a self-contained pellet production line in a single 30 m by 12 m building, with throughput from 1 to 2 tons per hour, fed by on-site sawdust, offcuts or agricultural residue. The defining feature is not the throughput - many small commercial lines run at the same rate - but the operating model: a single owner-operator, a single shift, and a small local market for the pellets. The plant is sized so that a millwright can install it, a farmer can run it, and a regional haulier can deliver the finished pellets to a school or a greenhouse within 50 km.
Where a Homemade Plant Beats a Commercial Plant
A 5 tph commercial pellet plant needs a procurement manager, a QC lab, an ENplus auditor and a maintenance team. A homemade plant needs the owner and one helper. That single difference is the reason 60 percent of Mikim's 2024 deliveries in the 1 to 2 tph window went to farms, small sawmills and rural heating cooperatives, not to industrial biomass investors. The economics work because there is no payroll beyond the owner, and the pellets sell for heating at a price the local coal or heating oil alternative cannot match.
Where a Homemade Plant Does Not Work
If the raw material has to be trucked in from more than 80 km, the freight kills the margin. If the target market is industrial boilers more than 200 km away, the plant is too small to supply reliably. And if the operator is not willing to spend two weeks learning the dryer and the mill controls, the line will produce fines, not pellets, for the first six months. The Mikim quotation includes a seven day commissioning visit specifically to avoid that last trap.
What Is Included in a 1-2 tph Turnkey Package
A Mikim homemade pellet plant is shipped as a single line of equipment that arrives in two 40 foot containers. The quotation line by line is the same for every customer, which makes it easy to compare competing offers.
Homemade Biomass Pellet Plant
| Section | Equipment | Main Motor (kW) | Footprint (L x W x H m) |
|---|---|---|---|
| Raw material reception | Screw conveyor + buffer bin (5 m3) | 2.2 | 4.0 x 1.5 x 2.5 |
| Size reduction | Hammer mill with 3 mm screen | 55 | 2.4 x 1.4 x 2.0 |
| Drying | Rotary drum dryer (8 tph wet in) | 15+7.5 | 7.0 x 1.8 x 2.6 |
| Pellet milling | MZLH-420 ring die pellet mill | 90 | 2.0 x 1.5 x 2.0 |
| Cooling | Counter-flow cooler (SKLN-2) | 5.5 | 3.5 x 1.5 x 2.4 |
| Screening and bagging | Vibrating screen + bagger | 1.5+2.2 | 3.0 x 1.2 x 2.2 |
| Dust collection | Cyclone + pulse filter | 4.0 | 1.5 x 1.0 x 3.0 |
Total connected load is about 185 kW, and realistic running load at 1.5 tph is 130 to 145 kW. A three-phase 380 V at 50 Hz supply is required; a diesel generator is not recommended because the running cost of the mill at 1.5 tph is dominated by the electricity bill.
Optional Add-ons Worth Buying
Three add-ons that are not in the standard quotation but pay back within the first year on a 1.5 tph line: a soft-start inverter on the main motor (saves the gearbox from shock loading during the morning warm-up), a moisture probe at the dryer outlet (avoids the most common cause of die choking), and a metal detector on the conveyor feeding the mill (one nail can wreck a ring die). All three together cost less than 5 percent of the line and save the operator months of downtime.
How to Choose the Right Throughput for Your Farm
The 1 tph and 2 tph packages are not just different sizes; they are different decisions.
Pick the 1 tph Package When
You have 1 500 to 2 500 tons of raw sawdust or offcuts per year, the local pellet market is residential heating, and the operator will spend 60 percent of the day on raw material handling and 40 percent on the mill. The 1 tph package is also the right choice for a first-time owner-operator who has never run a pellet mill before - a 1 tph line forgives more mistakes than a 2 tph line.
Pick the 2 tph Package When
You have 3 500 to 6 000 tons of raw material per year, the local market is a mix of residential and small commercial (greenhouses, schools, district heating), and you can fund a second shift worker. The 2 tph package assumes the operator is confident with the mill and is willing to run two 8 hour shifts rather than one 12 hour shift.
Production Guide for a New Homemade Plant
Most new plant owners lose money in the first 60 days because they skip two of the four steps below. They are the steps that turn a collection of metal boxes into a pellet line.
Step 1: Foundation and Electrical, 14 Days Before Delivery
A homemade 1.5 tph line needs a 200 mm reinforced concrete slab with isolator pads under the mill, a three-phase 380 V supply with a 400 A breaker, and an exhaust stack 8 m above the cyclone. None of this is in the Mikim quotation, but every one of these items is on the Mikim pre-delivery checklist. Get them done before the containers arrive.
Step 2: Mechanical Installation, 4 to 6 Days
Two Mikim fitters plus a local electrician and plumber can install the line in 4 to 6 days. The conveyors are pre-wired, the cyclone arrives as a single piece, and the mill is bolted to its isolator pads. Plan for a forklift and a 5 ton crane for the dryer and the cooler.
Step 3: Commissioning, 5 to 7 Days
The Mikim commissioning engineer starts the line at low throughput, ramps to 1.5 tph, and walks the owner through the dryer temperature, the mill motor current, the cooler discharge temperature and the screening mesh. The owner runs the line on day 6 and 7 of commissioning with the engineer on standby.
Step 4: First 30 Days of Operation
In the first 30 days the operator should expect a 10 to 15 percent loss in output compared to the commissioning day. The die needs to wear in, the operator needs to learn the moisture window, and the dryer needs to settle into the local ambient conditions. After 30 days the line should be running at 1.4 to 1.5 tph for 8 hours per day on a single shift.
| Milestone | Target Output | Notes |
|---|---|---|
| Day 1-2 commissioning | 0.8 tph | Die and rollers are new, throughput limited |
| Day 8-15 | 1.2 tph | Die has worn in, motor current has stabilised |
| Day 16-30 | 1.4 tph | Operator is confident with moisture and current |
| Day 31-90 | 1.5 tph | Line is in steady state, fines below 1 percent |
Plant Layout for a 1.5 tph Homemade Plant
A 30 m by 12 m clear-span steel portal frame at 6 m eaves height is sufficient. The raw material reception and hammer mill are at one end, the dryer along the long wall, and the pellet mill, cooler and bagging line on the opposite side. A small 3 m by 3 m office and electrical room is sufficient for one operator and the control panel. The whole building can be unheated if the plant is in a temperate climate, but the gearbox oil heater and the mill feed chute heater must be installed if winter temperatures drop below -5 degrees C.

Frequently Asked Questions
If you are thinking about a homemade biomass pellet plant, these are the questions new owner-operators ask most often. Each answer is based on what Mikim has actually seen work on 50 or so 1-2 tph plants commissioned between 2023 and 2025, in Europe, North America and Southeast Asia.
Q: How much does a 1-2 tph homemade biomass pellet plant cost?
A complete 1 tph Mikim line in a 40 foot container typically ships for USD 85 000 to 110 000 CIF, and a 2 tph line for USD 130 000 to 170 000 CIF, depending on the destination port and the optional add-ons. Civil works, electrical supply and the building are not included and typically add another USD 30 000 to 60 000 at the customer's site.
Q: Can one person run a 1.5 tph pellet plant alone?
Yes, for a single 8 hour shift. A trained operator can run the line, monitor the dryer and the mill, screen the finished pellets, and bag them on a single shift. For a 2 tph line or a two-shift operation, a second operator is required. Mikim's commissioning includes 5 days of hands-on training so the operator can run the line alone from day 8 onward.
Q: What raw materials can the homemade plant run?
Softwood sawdust, hardwood sawdust, wood shavings, offcuts from a joinery workshop, and dry agricultural residue such as straw or bagasse. The key is the moisture content (10 to 14 percent) and the particle size (below 4 mm). The Mikim hammer mill with a 3 mm screen produces the correct particle size for the MZLH ring die mill in the package.
Q: How long does it take to install a homemade biomass pellet plant?
Two Mikim fitters plus a local electrician and plumber need 4 to 6 days for the mechanical install. The first batch of pellets is usually produced on day 6 of commissioning. A conservative total timeline from container arrival to full output is 10 to 14 days, assuming the foundation and electrical are ready when the containers arrive.
Q: What is the payback period for a homemade biomass pellet plant?
For a 1.5 tph plant in a market where pellets sell for USD 180 to 220 per ton and sawdust is available at zero or negative cost, the typical payback is 18 to 30 months. In markets with cheaper pellets and more expensive sawdust, the payback is 30 to 48 months. Mikim includes a payback worksheet in every quotation so the buyer can plug in the local numbers.
