Pakistan customer purchases SL-50 briquette press machine for sawdust briquette production
Table of Contents
A furniture manufacturer in Lahore, Pakistan needed a reliable way to convert his hardwood sawdust into a saleable solid fuel.
After comparing Turkish, Indian and Chinese suppliers, he chose Shuliy’s SL-50 biomass briquette press machine to start a compact sawdust briquette line for the local fuel and hookah markets.
The press now runs 8 hours a day and produces around 2 tons of finished Pini Kay briquettes per shift.
Customer background: a Lahore furniture workshop with a sawdust problem
The customer runs a 12-year-old furniture workshop. He supplies dining sets, beds and office furniture to wholesalers. His band saws, planers and edge banders generate 12–15 tons of mixed hardwood sawdust every month.
Until 2025, the sawdust was either burned in a low-efficiency brick kiln or given away to local brick factories for almost no return. With winter LPG prices climbing and the local hookah (shisha) fuel market actively looking for cheaper solid-fuel alternatives, he decided to turn the waste stream into a Pini Kay briquette product and sell it back into the same Punjab and Sindh markets he already served.
The production challenge: weak briquettes from the old press
His first attempt used a small Indian screw press running directly off planer dust. The briquettes came out soft, cracked during cooling, and lost more than 30% of their weight as fines.
The root causes were an underpowered motor, no heated barrel, and a low-pressure extrusion screw that could not compress the sawdust above 0.9 g/cm³.
He needed a proper wood briquette making machine that could:
- Extrude 250 kg of sawdust per hour into dense Pini Kay rods with a centre hole
- Run on Pakistan’s standard 380 V / 50 Hz three-phase supply
- Hold tolerance on the 46–50 mm hexagonal profile that his buyers already accept
- Fit into a single wooden crate for affordable sea freight to Karachi
Our recommendation was the SL-50 wood sawdust briquette making machine — the same model we ship to buyers in Cambodia, Hungary, Germany and Turkey for hardwood and softwood sawdust.
Shuliy solution: SL-50 biomass briquette press
The SL-50 is a compact screw extruder designed for biomass that has already been dried below 12% moisture. Sawdust is fed through the hopper, pushed by the rotating screw through a heated barrel (260–380 °C), and forced out through a hexagonal die with a central pin. The continuous rod is then cut to length on the outlet tray. The heated barrel and the 18.5 kW motor give the SL-50 enough torque to push the sawdust above 1.0 g/cm³ — about 15–20% denser than the customer’s previous Indian press.

Why the SL-50 works for Pakistani hardwood sawdust
- Density that survives stacking and truck transport. The SL-50’s heated barrel and 18.5 kW motor extrude briquettes at 1.0–1.3 g/cm³, so the rods do not crack when stacked 10 layers high on a delivery truck to Sindh.
- The hexagonal Pini Kay profile buyers already expect. Local hookah-fuel wholesalers specifically ask for 46–50 mm hex rods with a centre hole. The SL-50 ships with that die as standard, so the customer could start selling on day one of production.
- Wear parts support. We included two spare screws with the shipment for the next 12 months.
For buyers who want to scale the same setup into a full sawdust briquette production line, the SL-50 forms the press core that we already ship in combination with dryers, conveyors and carbonization furnaces to similar buyers in South Asia, the Middle East and West Africa.
Packaging and shipment to Pakistan
The SL-50 briquette press machine was crated in a single fumigation-free wooden case lined with plastic film and steel-banded for sea freight.
Standard shipping documents (commercial invoice, packing list, certificate of origin, bill of lading) were emailed to the customer’s clearing agent in Karachi so the consignment cleared customs without delay.
Service and after-sales support
- Pre-shipment video test. The SL-50 was run on the customer’s actual hardwood sawdust sample in our workshop, and the test video was sent to the buyer before crating.
- English manual + wiring diagram. A printed operation manual, spare-parts list, and full electrical drawing for the 380 V / 50 Hz Pakistan grid were enclosed inside the crate.
- Remote commissioning. Our engineer joined the customer on WhatsApp video for installation guidance, screw alignment, heating-ring PID tuning, and the first 4 hours of briquette production.
- Wear-part kit included. Two spare heating rings and two spare screws are shipped with every SL-50 order, which covers roughly the first 6 months of two-shift operation.
