This specialized machinery integrates a vertical helical screw, commonly referred to as an auger, situated within a conical or cylindrical bucket-style vessel. The rotational motion of the screw lifts materials from the base of the container to the top, facilitating a continuous fountain-like circulation that ensures a uniform distribution of components. This vertical configuration is particularly advantageous for minimizing floor space requirements while maximizing mixing efficiency. The mobile nature of the unit, typically mounted on a heavy-duty chassis with caster wheels or integrated hitch points, allows for seamless transportation between different staging areas or job sites. Beyond simple blending, the high-torque auger system can often be configured for grinding applications, breaking down larger aggregates into finer consistencies. Common applications include the preparation of livestock feed in agricultural settings, the mixing of dry mortar or specialized concretes in construction, and the batch processing of chemical powders or plastic resins in manufacturing environments. Constructed from high-strength stainless or carbon steel, these mixers are designed for durability and ease of cleaning, often featuring discharge chutes or tilting mechanisms for streamlined material recovery.\u003cbr\u003e\n\u003cbr\u003e\nKEYWORDS: Mixer, Auger, Helical, Vertical, Mobile, Blender, Grinder, Bucket, Screw, Industrial, Agriculture, Processing, Machinery, Batch, Granular, Equipment, Construction, Homogenizer, Material, Engineering\u003cbr\u003e\n\u003cbr\u003e","imageAlt":"MOBILE BUCKET VERTICAL HELICAL AUGER SCREW MIXER 3D 1","url":"https://www.cgtrader.com/3d-models/industrial/tool/mobile-bucket-vertical-helical-auger-screw-mixer-blender-grinder","isCLDApplicable":false,"isSaleOffApplicable":true,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/jysf3ac1skhgy3gcnisjh22h3mv9/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/01_1536_MOBILE%20BUCKET%20VERTICAL%20HELICAL%20AUGER%20SCREW%20MIXER%20BLENDER%20GRINDER.jpg","gridUrl":"https://media.cgtrader.com/variants/jysf3ac1skhgy3gcnisjh22h3mv9/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/01_1536_MOBILE%20BUCKET%20VERTICAL%20HELICAL%20AUGER%20SCREW%20MIXER%20BLENDER%20GRINDER.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-models/industrial/tool/mobile-bucket-vertical-helical-auger-screw-mixer-blender-grinder","isCgtVerified":false,"types":{"printReady":false,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":5,"name":".fbx","is_native":false},{"id":13,"name":".3dm","is_native":false},{"id":25,"name":".dae","is_native":false},{"id":4,"name":".dwg","is_native":false},{"id":17,"name":".max","is_native":false},{"id":51,"name":".stl","is_native":false},{"id":12,"name":".obj","is_native":false},{"id":147,"name":".sat","is_native":false},{"id":2,"name":".3ds","is_native":false},{"id":72,"name":".stp","is_native":false},{"id":14,"name":".skp","is_native":false},{"id":29,"name":".ige","is_native":false},{"id":21,"name":".blend","is_native":false},{"id":117,"name":".gltf","is_native":false}],"categorySlug":"industrial","subcategorySlug":"tool","categoryTitle":"Industrial","subcategoryTitle":"Tool","schemaImageUrl":"https://img-new.cgtrader.com/items/7022390/ce085a0631/mobile-bucket-vertical-helical-auger-screw-mixer-blender-grinder-3d-model-ce085a0631.webp","saleOffDiscount":50,"eligibleForSubscription":false,"subscriptionSubscribed":false,"subscriptionPotential":false}},{"id":"7036775","type":"listingItem","attributes":{"id":7036775,"title":"MINI VERTICAL AUGER HELICAL AUTO PRESS INJECTION MOLDING PLASTIC","price":22.0,"description":"High-quality 3D assets at affordable prices — trusted by designers, engineers, and creators worldwide.

Print the single sphere with the flat cut facing the build plate, hole pointing directly upwards.\n\nSupports: Absolutely no supports for the central shaft! The sphere prints beautifully without internal supports.\n\nInfill: 10-15% (Gyroid or Cubic).\n\nPerimeters/Walls: 3 to 4 walls for structural rigidity, ensuring the internal splines remain strong during the passthrough action.\n\nEngineering Tips for a Perfect Print:\n\nBridging the Recesses: The contoured recesses at the poles create small \"arch\" overhangs. Pro Tip: Ensure your \"Bridging\" settings are enabled in your slicer. With a well-tuned cooling fan, your printer will easily bridge these small gaps.\n\nPerfect Tolerances: The model is engineered for a buttery-smooth sliding action. Ensure your printer is well-calibrated for dimensional accuracy.\n\nMastering the Bottom Fillet: Because the base of the sphere features a 2 mm fillet, the first few layers have a steep overhang. Print the first 3-5 layers very slowly (e.g., 15-20 mm/s) with maximum cooling to ensure it prints cleanly.\n\nZ-Seam Alignment: For the smoothest rotation, set your Z-seam to \"Random\" or carefully align it to the sharp inner corners of the star profile.\n\nSupport the Designer!\nIf you enjoyed my free models (Cone and Hourglass), please consider supporting my work by purchasing this premium Sphere! Your support motivates me to keep creating high-quality engineering designs for the community.","imageAlt":"Helical Sphere Kinetic Fidget Toy 3D print model","url":"https://www.cgtrader.com/3d-print-models/games-toys/toy/helical-sphere-kinetic-fidget-toy","isCLDApplicable":false,"isSaleOffApplicable":false,"gaAttributes":{},"primaryImage":{"gridFallbackUrl":"https://media.cgtrader.com/variants/tztem60g4iq9t4tdgv86h6ylc2yi/a26e47dab5f2d22c43d6c5ce4b4b46ecc30c70918878397cba1a10c1e35d7bfc/1.jpg","gridUrl":"https://media.cgtrader.com/variants/tztem60g4iq9t4tdgv86h6ylc2yi/78add9c2f02fbd73a43ffb3970be38683c5f15eff6ca849dc78c644f4ff9ce1b/1.webp","isAdultContent":false},"modelInfo":{"modelUrl":"https://www.cgtrader.com/3d-print-models/games-toys/toy/helical-sphere-kinetic-fidget-toy","isCgtVerified":false,"types":{"printReady":true,"animated":false,"pbr":false,"rigged":false,"lowPoly":false}},"metaverseFormatsList":[{"id":59,"name":".sldprt","is_native":true},{"id":129,"name":".3mf","is_native":false},{"id":191,"name":".amf","is_native":false},{"id":210,"name":".x_t","is_native":false},{"id":51,"name":".stl","is_native":false},{"id":72,"name":".stp","is_native":false}],"categorySlug":"games-toys","subcategorySlug":"toy","categoryTitle":"Games \u0026 Toys","subcategoryTitle":"Toys","schemaImageUrl":"https://img-new.cgtrader.com/items/6858355/07baccd7ff/helical-sphere-kinetic-fidget-toy-3d-model-07baccd7ff.webp","saleOffDiscount":0,"eligibleForSubscription":true,"subscriptionSubscribed":true,"subscriptionPotential":false}},{"id":"5389676","type":"listingItem","attributes":{"id":5389676,"title":"Da Vinci Inventions -

The extrusion line is engineered to process raw polymer materials such as High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), and Polypropylene (PP). The process begins at the feed hopper, where resin pellets enter a heated barrel. A precision-engineered screw rotates within the barrel to melt, mix, and compress the polymer before it is forced through a die to form the desired pipe shape. Following extrusion, the profile enters a vacuum calibration and cooling tank to ensure structural integrity and dimensional consistency. The integrated recycling component allows the system to reclaim production waste by shredding and re-granulating scrap material, promoting a circular economy within the manufacturing facility. This assembly includes detailed representations of the drive motors, control panels, haul-off units, and automated cutting stations. Such machinery is vital for infrastructure projects, including water distribution, sewage systems, and telecommunications ducting.

I mainly build this thing jut for fun and to show people what the possibilities are with 3D-printed parts because some people still think 3D-prints are not functional and you can only make vases, figures or boats with a 3D-printer. 3D-printed parts of course have their limits like you'll see in the video ;-). Almost every part in this build is 3D-printed, except for the shafts bearings, nuts and bolts etc.\n\nTo drive the shredder i used the gearbox i mentionned above. Video can be found here:\nhttps://youtu.be/d8us3OWgS1A\n\nThe gearbox was powered by a 3S 2200mah LIPO battery With the help of the Universal Motion Controller i made. It's possible to run the gearbox on a 6S LIPO but this would destroy the gears almost immediately in this application.\n\nThank you to Banggood for providing me with the Ender-3 V2 3D-printer.You can

The original one had a gear ratio of 30:1 and the speed of the output shaft was about 715 RPM which made it difficult to tune in the right PID parameters. This new version has a gear ratio of about 162:1 which lowers the speed and increases the torque of the output shaft.\n\nI choose to go for double helical gears on this one because they produce a lot less noice than regular spur gears and the forces on the teeth are transferred more gradually. The gears rotate around a 6mm stainless steel shaft which is lubricated with bearing grease. Ideally all the gears should have some bearings, this is being considered for the next moment. Unlike my previous design I used 2 20mm bearings to support the output shaft.\n\nThe servo uses a 775 36V 9000rpm brushed DC-motor which is driven by my Universal Morion Controller (UMC)(\nhttps://www.thingiverse.com/thing:4245315\n). The stall torque theoretically is about 297kg/cm, I was able to test the servo to a torque of about 132kg/cm. During testing none of the gears broke, they were all printed in PLA. The weak link in this design however where the mounting tabs and the bevel gears used in the first stage on the motor shaft. These 2 gears tend to slip under high loads ,like when i tried to pull the car forwards with it's handbrake on, but this didn't occur when i performed the test where it pulled 132kg/cm of torque so it should be fine to at least this torque rating.\n\nVideo can be found here:\nhttps://youtu.be/d8us3OWgS1A\n\nMore info can be found

modifier that moves vertices around but does not change topology (adding or deleting vertices, faces, surfaces, lines, etc.) Examples of similar 3ds Max modifiers are Bend, Stretch, and taper.\n\n\nThis script is as the same as standard Bend, but with additional settings for spiral mode.\n\n\nThis logarithmic spiral can be seen and is very widely used in many cases in the nature. In addition, it helps you to create a more correct form in the designing of many metal, wooden and plaster objects.\n\n\nIt is called Logalithmic Spiral or Fibonacci in mathematics.\n\n\n**How to use?**:\nTo use it, just put the script in the Max Startup folder so that Max recognizes it at the next start. In this case, a new modifier which is named \"__QM__SpiralBend\" will appear in the list of modifiers. Then it is possible to select and apply it to the object.\n\n\n**Startup directory**:\n- C:\\Program Files\\Autodesk\\3ds max 20XX\\scripts\\Startup\n\n\n**Note**: in 3DsMax 2015 sometimes when any scripted modifier (even the examples provided by the MaxScript reference) is added to the object, 3DsMax crashes. Unfortunately, this cannot be fixed by us.\n\n\nThe file is in .mse format and encrypted.\n\n\nIf you find any problem, please let us know.\n\n\nThank you for choosing this script.\n\n","imageAlt":"QM

You can print these parts with 3d printer and it's works harmoniously. You know this things provides a linear movement.  I used 775 motor (100 watt) and I get a cool results. So the maximum axial load theoritically 250 Newton(~25 kg or ~ 56 lb). But if you use 775 motor which is one of 150 watt, this time axial load will theoritically 380 Newton (~38 kg or ~ 85 lb). The Piston stroke is 120 mm and piston speed about 30 mm/s. So 4 sec to required to full stroke. \nThere is a small gearbox in the system. It has a 6 gear ratio. I used helical gears and they have m=0.8 mm and m=1 mm normal modules. The threaded rod is 8 mm diameter (M8) and the shaft of second stage has a 6 mm diameter. Nuts also M8. I used three 608zz ball bearings for support to threaded rod. \nIf you make this project, The body does not need to be so strong. Because the body only meets the friction force between the lead screw and the nut. So you can print with %20 infill and 0.2 mm layer height for stationary parts.\nYou should print the gears with lower layer height (0.12 mm -0.16 mm).

A PLANETARY REDUCTION DRIVE IS A SMALL SCALE VERSION USING BALL BEARINGS IN AN EPICYCLIC ARRANGEMENT INSTEAD OF TOOTHED GEARS.\n\n\nREDUCTION DRIVE (ALSO WITH A TRANSFORMATION OF THE DIRECTION OF ROTATION)\nREDUCTION DRIVES ARE USED IN ENGINES OF ALL KINDS TO INCREASE THE AMOUNT OF TORQUE PER REVOLUTION OF A SHAFT: THE GEARBOX OF ANY CAR IS A UBIQUITOUS EXAMPLE OF A REDUCTION DRIVE. COMMON HOUSEHOLD USES ARE WASHING MACHINES, FOOD BLENDERS AND WINDOW-WINDERS. REDUCTION DRIVES ARE ALSO USED TO DECREASE THE ROTATIONAL SPEED OF AN INPUT SHAFT TO AN APPROPRIATE OUTPUT SPEED. REDUCTION DRIVES CAN BE A GEAR TRAIN DESIGN OR BELT DRIVEN.\n\nPLANETARY REDUCTION DRIVES ARE TYPICALLY ATTACHED BETWEEN THE SHAFT OF THE VARIABLE CAPACITOR AND THE TUNING KNOB OF ANY RADIO, TO ALLOW FINE ADJUSTMENTS OF THE TUNING CAPACITOR WITH SMOOTH MOVEMENTS OF THE KNOB.
