Industrial Drum Chipper Machine for Biomass Briquetting Lines Large-scale biomass briquetting plant requires a reliable and efficient first-stage size reduction process. UT Machinery designs and manufactures heavy-duty drum chipper machine engineered to process large-diameter logs, wood scraps, tree branches, and industrial pallets into uniform wood chips. Compared with conventional wood crushers, a dedicated drum chipper eliminates feeding bottlenecks caused by irregular raw materials and provides a stable, continuous material flow for downstream drying and fine grinding. The wood chips produced by a drum chipper are widely used as feedstock for biomass briquetting, wood pellet manufacturing, biomass boilers, and renewable energy applications. Consistent chip size, controlled moisture content, and uniform raw materials help improve processing efficiency and support the production of biomass fuels that meet internationally recognized quality requirements, such asISO 17225. Drum Chipper Machine Structural Design & Key Features 01 Heavy-Duty Hydraulic Feed and Chain Plate System Unlike standard gravity-fed or light-duty belt units, our wood drum chipper machines utilize a rugged chain plate infeed conveyor paired with a hydraulic upper feed roller. The teeth on the roller actively grip logs and irregular wood scrap, pulling them steadily into the cutting assembly without manual intervention or bridging. 02 Optimized Cutting Rotor & Knife System The heart of the machine is a precision-balanced steel drum rotor equipped with specialized fly-knives and stationary dead-knives (anvils). This design delivers a clean, shearing cut rather than a blunt impact, reducing overall power consumption per ton and ensuring high throughput even when processing dense hardwoods. 03 Direct Integration with Briquette Production Line We design these drum chippers as modular front-end components. Based on your plant’s footprint, we customize the discharge conveyor height and angle to feed directly into your rotary dryer or primary hammer mill buffer hopper, achieving an automated, continuous production workflow. How Does a Drum Chipper Machine Work? The drum chipper uses a continuous feeding and precision cutting process to achieve high-capacity wood size reduction. Typical workflow: Raw Logs & Wood Waste ↓ Chain Plate Conveyor Feeding ↓ Hydraulic Feed Roller Compression ↓ High-Speed Drum Rotor with Chipping Knives ↓ Uniform Wood Chips (30–50 mm) ↓ Rotary Dryer ↓ Hammer Mill ↓ Biomass Briquette Machine This automated workflow minimizes material blockage while ensuring a continuous supply of uniform chips for downstream processing.

A1: A wood drum chipper uses precise shearing action via rotating knives to slice large logs and wood blocks into clean, flat chips (30-50mm), which is highly efficient for bulk primary reduction. A standard crusher or hammer mill relies on blunt hammers to shatter materials, which requires more power and is typically used for secondary fine grinding. Q2: Can the machine process wooden pallets that contain nails? A2: Yes, it can process standard industrial pallets. However, if your raw material consistently contains large amounts of scrap metal or heavy nails, we recommend installing a cross-belt magnetic separator on the discharge conveyor to protect downstream drying and briquetting equipment. Q3: How do we control and adjust the final output chip size? A3: The output size is primarily determined by two factors: the feeding speed of the hydraulic rollers relative to the rotor speed, and the mesh size of the built-in discharge screen located beneath the cutting drum. The screen ensures that oversized pieces are retained for re-chipping. Q4: What wear parts require regular maintenance? A4: The primary wear items are the chipping knives (fly-knives and counter-knives). These will require periodic sharpening depending on whether you are processing clean logs or dirty scrap wood. We supply complete maintenance kits and detailed guidelines for quick knife replacement to minimize downtime. Q5: What moisture content is recommended before chipping? Fresh wood with high moisture content can be chipped directly. However, if the chips are intended for biomass briquette or pellet production, they are typically dried to below 10–15% moisture before further grinding and densification.

Frequently Asked Questions Q1: What is the ideal moisture content for biomass briquetting? For most biomass materials like sawdust and straw, the ideal moisture content is between 10% and 15%. If the moisture is higher, the briquettes may crack or steam during extrusion. Our rotary dryer is designed to reduce moisture from 50% down to this optimal range in a single pass. Q2: Can the UT Machinery Rotary Dryer handle different types of biomass in one machine? Yes. Thanks to our Variable Frequency Drive (VFD) system, you can adjust the drum’s rotation speed and the residence time of the material. This allows the same machine to switch between light materials like rice husk and denser materials like wood chips effectively. Q3: How do you prevent the biomass from catching fire inside the dryer? Safety is our priority. We integrate real-time temperature sensors at the discharge end. By monitoring the air temperature and controlling the heat source (hot air furnace), we ensure the material stays below its ignition point while still achieving maximum drying efficiency. Q4: What heat sources can be used with the rotary dryer? Our drying systems are flexible. You can use biomass burners (using your own waste wood or pellets), coal, natural gas, or oil furnaces. For eco-friendly operations, we highly recommend our biomass-fired hot air furnaces. Q5: Do you provide the full production line layout? Absolutely. UT Machinery specializes in turnkey solutions. We can design the entire layout, ensuring the rotary dryer is perfectly synchronized with your crushers and briquette presses to prevent bottlenecks and maximize output.

Product Overview Long, tangled metal scrap such as steel turnings, aluminum swarf, and copper chips occupies valuable storage space and often causes feeding problems in briquetting systems. The Industrial Metal Crusher is designed to reduce oversized metal scrap into uniform granules before briquetting. Using a low-speed, high-torque dual-shaft shearing system, it processes continuous machining waste into particles typically ranging from 10–50 mm, creating a consistent feedstock for downstream equipment. Suitable for steel, cast iron, aluminum, copper, and brass machining scrap, the crusher helps improve material handling, stabilize production, and increase briquette density in automated metal recycling lines. What Materials Can the Industrial Metal Crusher Process? Instead of manually cutting or handling bulky machining waste, the crusher automatically processes a wide variety of metal scrap generated during turning, milling, drilling, and machining operations. Suitable materials include: Long steel turnings Bird-nest steel swarf Cast iron borings Aluminum swarf and shavings Copper chips Brass turnings Wet metal chips containing cutting oil Mixed machining scrap Not recommended for: Solid metal blocks Heavy structural steel Thick steel plates over 10 mm Large forgings or castings Why Crush Metal Scrap Before Briquetting? Long metal turnings frequently bridge inside hoppers, wrap around feeding mechanisms, and interrupt continuous production. After crushing, uniformly sized particles offer several operational advantages: Without CrushingAfter CrushingTangled metal swarfUniform 10–50 mm granulesFrequent hopper bridgingSmooth material flowIrregular feedingStable automatic feedingLower briquette densityHigher compaction efficiencyMore operator interventionContinuous automated operation How the Crusher Fits into a Briquetting Line The Industrial Metal Crusher serves as the first processing stage in an automated metal briquetting system. Typical production flow: Metal Scrap → Industrial Metal Crusher → Belt Conveyor → Centrifugal Dewatering Machine → Hydraulic Briquetting Press → Finished Metal Briquettes Uniform particle size improves conveyor efficiency, increases oil recovery during centrifugal drying, and allows the briquetting press to produce denser, more consistent briquettes. Key Engineering Features High-Torque Dual-Shaft Shearing Two counter-rotating shafts operating at low speed generate high shearing force without excessive impact. Compared with high-speed hammer mills, this design reduces dust generation, lowers operating noise, and minimizes blade wear. Wear-Resistant Alloy Steel Blades Each cutter is manufactured from heat-treated SKD-11 / D2 chromium-molybdenum alloy steel with a hardness of HRC 58–62. The hook-shaped blade profile grips tangled machining scrap automatically, reducing the need for manual material preparation. Siemens PLC Protection System Current sensors continuously monitor shaft load. When oversized objects or unexpected overloads occur, the PLC automatically reverses shaft rotation to clear blockages, protecting both the gearbox and drive motor. Easy Maintenance A hydraulically opened split chamber provides quick access for inspection and cleaning. Individual blades can be replaced or re-sharpened independently, reducing maintenance cost and minimizing downtime.
