Application scope:

Widely applicable to granulation products in industries such as sludge, fertilizer, rubber additives, food additives, plastic additives, powdered activated carbon, catalysts, feed, pesticides, dyes, pigments, daily chemical products, pharmaceuticals, etc.

Wet materials or materials with low softening points (generally less than 60 ℃) that have been mixed and kneaded are extruded from the opening of the die template under the squeezing force generated during the screw conveying process, forming a strip shape; After drying or cooling, short columnar granular products are obtained, thereby achieving the goal of transforming powdered products into uniform granular products. The natural fracture length depends on the bonding strength of the material and is generally within the range of 1.25-2.0 times the diameter. For pre extruded types with special requirements for length, the method of external cutting can be used to obtain relatively uniform particle products.

Equipment features:

1. This machine is dedicated to the research of powder preparation processes such as catalysts, adsorbents, and submerged feed, as well as small and medium-sized production. It has strong industry specificity and a wide range of applications.

2. The equipment has high processing accuracy, can provide large extrusion pressure, and can achieve material forming with a diameter of 0.5mm.

3. A digital real-time extrusion pressure display device is specially configured for scientific research and process testing. The relationship curve between extrusion pressure and product strength can be measured to seek the optimal process point and provide a basis for parameter calculation of production equipment processes.

4. Fully leverage the advantages of our factory in metal materials and heat treatment, provide a variety of accessories made of different materials according to user materials, significantly improve the service life of consumables such as screws and extruders while ensuring corrosion resistance, and reduce user usage costs.

5. The screw is protected by pressure sensors with adjustable pressure limits.

6. Adopting variable frequency speed regulation, the screw is infinitely adjustable, and the speed is displayed in real time, which can be adjusted according to the characteristics of different materials.

7. Various cylindrical and irregular orifice plates can be customized as needed.

8. Adopting a front extrusion structure, the structure is simple, easy to use, and the equipment failure rate is extremely low.

9. Easy to clean and replace, convenient for laboratories that frequently change formulas.

10. All parts in contact with the material are made of stainless steel.

11. Customization can be made according to the user's actual formula and process requirements.

Equipment structure:

The feeding hopper, spiral feeder, extruder, and extruder head orifice plate are all easy to disassemble and clean.

The screw structure causes the material to be squeezed by the forward thrust of the rotating screw, resulting in uniform squeezing and high forming rate, as well as dense finished particles; Continuous operation, high production efficiency; Can simultaneously supply materials for multiple rolling machines to produce pellets.

Provide multiple aperture screens for easy regulation to obtain extruded materials of different diameters.

Adopting frequency conversion speed regulation, it can adjust the speed within a certain range to meet the different requirements of different materials for speed, adjust the extrusion speed in real time, and achieve the best extrusion effect. Expand the range of variety selection.
