That’s an excellent and critical question, as wear parts are the primary operational cost for any extrusion machine.
Our screw propellers and molds are not made from standard hardened steel. They are investment-cast from a high-chromium alloy (Cr12MoV), which is then subjected to a specialized heat treatment process. This results in a Rockwell hardness of over HRC60.
Here’s what that means for you in practical terms:
Lifespan: While standard steel parts might need replacement after processing 50-80 tons of material, our high-chromium components are engineered to reliably process 300-400 tons of charcoal powder before requiring replacement. The exact lifespan will vary slightly with the abrasiveness of your specific raw material (e.g., high-silica content biomass may be more abrasive).
Performance: This superior hardness doesn’t just mean longer life; it ensures consistent briquette density and shape over the entire operational cycle.
Conclusion: You are investing in significantly fewer shutdowns for maintenance and a lower cost-per-ton produced, directly boosting your profitability. We also keep a full inventory of these replacement parts for immediate shipment to minimize your downtime when the time eventually comes.

This is a crucial point, and we believe in being transparent. The “2-3 tons per hour” rating is the machine’s mechanical capacity under ideal conditions. Achieving it consistently depends on optimizing your production workflow.
The three most critical factors are:
Raw Material Preparation: The powder must be of a consistent, fine mesh (ideally 80-100 mesh). Larger, inconsistent particles will reduce efficiency.
Moisture Content: This is the single most important variable. For most charcoal powders, the optimal moisture content for extrusion is between 25-30%.Too dry (<20%): The material will cause excessive friction and heat, reducing output and accelerating wear on the screw.
Too wet (>35%): The briquettes will be soft, difficult to handle, and may not form properly, leading to blockages.
Binder Mixing: The binder (like corn or cassava starch) must be mixed absolutely uniformly with the powder and water. Our recommendation is to use a wheel grinder mixer for this task, as it ensures a homogenous mixture that flows smoothly into the extruder.
To help you succeed, we offer a valuable service: you can send us a 15-20 kg sample of your raw material, and we will conduct a free test run. We will determine the optimal moisture and binder ratio for your specific material and provide you with a video of the test and the resulting briquettes, giving you a precise operational baseline before you even purchase.

You’ve identified the difference between a machine that simply makes briquettes and one that manufactures a premium product. The final quality is a partnership between the machine’s power and the material’s preparation.
Here is how we ensure high-density, durable briquettes:
Optimized Screw-to-Barrel Clearance: The clearance between our screw propeller and the barrel wall is precision-engineered to be extremely tight. This minimizes material backflow and maximizes forward pressure, creating immense compaction force that results in very high briquette density.
Tapered Barrel Design: The machine’s barrel is slightly tapered, gradually increasing pressure as the material moves toward the mold. This progressive compression squeezes out air pockets and ensures a solid, void-free internal structure.
Process Control Guidance: The machine provides the pressure, but the “glue” that holds the briquette together is the correctly activated binder. We provide detailed guidance on binder selection (e.g., cassava starch for its excellent binding properties) and the crucial step of adding the right amount of water to create a paste-like consistency. A strong briquette is born in the mixer; our machine gives it its final, dense form.
By combining our machine’s immense and consistent pressure with proper material preparation, you will produce briquettes that are structurally sound and can easily withstand the rigors of handling and shipping.

That’s an insightful question, and the answer depends entirely on your production goals. Both technologies have their place.
Hydraulic Presses: These are excellent for creating very high-density, smaller tablets or cubes under immense static pressure. They are often favored for high-end, perfectly uniform shisha/hookah charcoal tablets. However, their primary drawback is that they are batch-process machines, meaning their production cycle is start-and-stop, resulting in a significantly lower overall output (kg per hour).
Screw Extruders (Our Machine): Our machine is a continuous-process machine. Once it’s running, it produces a continuous rod of briquettes at a very high speed. This makes it vastly more efficient for producing larger quantities of BBQ charcoal or fuel rods.
Key Advantage for BBQ Charcoal: The extrusion process naturally allows for creating shapes with a central hole (like hexagonal or square with a hole), which is highly desirable for BBQ charcoal as it improves airflow and ensures more even burning. This is difficult or impossible to achieve with a standard hydraulic press.
