The Shuliy hydraulic sawdust briquette machine offers two mold options: 60 mm and 70 mm diameter. Both molds run on the same machine. A mold change takes approximately 30 minutes.
The right choice depends on your buyer’s equipment, not your machine. Choose 60 mm for household stoves and small commercial cookers. Choose 70 mm for industrial boilers and long-burn heating markets. Most producers serve both segments and keep both molds in rotation.
Below is a breakdown based on real market feedback from customers in Africa, Europe, and Southeast Asia.
How Does Sawdust Briquette Size Affect Burn Time and Output?
Briquette diameter determines burn behavior. This is physics, not marketing.
60 mm briquettes ignite faster and reach cooking temperature quickly. They fit standard household stove openings. A 60 mm briquette burns approximately 60–90 minutes in an open charcoal stove.
70 mm briquettes burn longer. The larger diameter reduces air exposure at the core. A 70 mm briquette burns approximately 90–120 minutes under the same conditions. Ignition takes longer because the center heats more slowly.
Production rate stays the same. The SL-60 machine delivers roughly 80 kg per hour with either mold. However, piece count differs. At 80 kg/h, 60 mm briquettes yield approximately 1,500 pieces per hour. The same output in 70 mm yields approximately 1,100 pieces per hour. Some markets negotiate price per piece, not per kilogram. This affects your revenue calculation.
60mm Sawdust Fuel Briquettes: Best Household Markets
Based on customer feedback, 60 mm sawdust fuel briquette machine output dominates in these applications:
East and West African Cooking Fuel
Kenya, Uganda, Ghana, and Nigeria have large installed bases of charcoal stoves (called jiko stoves in East Africa). These stoves have small combustion chambers designed for lump charcoal. A 60 mm briquette drops in directly. A 70 mm briquette requires splitting, which discourages repeat buyers.
Feedback from Nairobi and Kampala confirms: briquettes above 65 mm face resistance in household retail. Vendors report slower turnover for oversized pieces.
Small Restaurants and Street Food
Street food vendors cook in short sessions between customers. They need fast ignition and quick heat. The 60 mm format fits clay stoves and small metal cookers common in urban African and Southeast Asian food markets.
70mm Biomass Sawdust Briquettes: Industrial and Heating Markets
Customer feedback shows 70 mm biomass sawdust briquette machine output performs better in these segments:
Industrial Boilers and Kilns
Factories, brick kilns, and industrial boilers have large combustion chambers. Burn duration matters more than ignition speed. A 70 mm briquette extends refueling intervals from hourly to every 90–120 minutes. Boiler operators consistently prefer this format.
European Heating Stove Market
The European wood briquette market (Germany, Poland, Scandinavia) uses round “Nestro”-type briquettes with standard diameters of 60–90 mm. The 70 mm format fits log-burning stoves and fireplace inserts designed for split wood 70–100 mm thick. In cold-climate residential heating, buyers load stoves at night and expect heat until morning. 70 mm matches this pattern.
Sawdust Briquette Size Comparison: 60mm vs 70mm
| Factor | 60 mm Briquettes | 70 mm Briquettes |
|---|---|---|
| Burn time (open stove) | 60–90 minutes | 90–120 minutes |
| Ignition speed | Fast | Slow |
| Fits household charcoal stoves | Yes, direct fit | Requires splitting |
| Fits industrial boilers | Yes, frequent refueling | Preferred |
| Preferred European stove market | Secondary | Primary format |
| Pieces per 80 kg/h | Approximately 1,500 | Approximately 1,100 |
| Common pricing basis | Per piece or per kg | Per kg |
Which Sawdust Briquette Size Sells in Your Region?
Regional recommendations based on actual customer order patterns:
| Target Market | Recommended Size | Reason |
|---|---|---|
| Kenya, Uganda, Tanzania | 60 mm | Jiko stove compatibility |
| Ghana, Nigeria | 60 mm | Household cooking dominance |
| South Africa | 60 mm | Braai and household market |
| Germany, Poland, Scandinavia | 70 mm | Nestro stove standard |
| Nepal, Northern India | 70 mm | Overnight heating demand |
| Indonesia, Vietnam | 60 mm | Food stall cookers |
| Industrial boiler buyers | 70 mm | Long burn time |
If your market is undecided, start with 60 mm. Household cooking fuel has the largest global demand and fastest turnover. Add 70 mm molds when boiler or heating buyers appear.
Producing Both Sizes with One Sawdust Briquette Machine
Yes, one sawdust fuel briquette machine runs both molds. A typical dual-market schedule:
- Morning shift (6 hours): 60 mm for household fuel orders
- Afternoon shift (4 hours): 70 mm for boiler and heating orders
Mold swap takes 30 minutes including alignment and test pressing. Keep a spare mold set for each size so worn molds never stop production.
Package the two sizes separately and distinctly. Buyers who ordered 60 mm will reject a mixed load. Use different bag colors or clear size markings.
What Do Sawdust Briquette Machine Buyers Check Before Ordering?
Beyond diameter, market feedback shows buyers verify three things before repeat orders:
Density. A briquette that crumbles in hand gets rejected regardless of size. The hydraulic press reaches 60–70 MPa, producing dense briquettes. Test: drop one briquette from one meter onto concrete. It should not break.
Moisture. Briquettes above 8% final moisture feel heavy and smoke at ignition. Air-dry before packaging in humid climates.
Ash content. Sawdust source determines ash. Pure wood sawdust burns clean. Contaminated sawdust (soil, paint, treated wood) creates high ash and loses repeat buyers.
Order the Right Mold Set for Your Sawdust Briquette Machine
Briquette size is a market decision, not a machine limitation. The Shuliy hydraulic sawdust briquette machine handles both 60 mm and 70 mm on one frame, with both mold sets included.
Contact Shuliy with your target market and stove type. We supply both molds as standard and share region-specific feedback from existing customers in your market.
