Small screw conveyor is used to quantitatively and continuously feed fine powder and ultra-fine powder from the storage bin or hopper to the receiving device.
Spiral diameter: 100mm-250mm
Conveying length: 100mm-2000mm
Conveying capacity: 0.01kg/hour—1000kg/hour
Dosing range: 0-100g/h, 100-1000g/h, 1-5Kg/h, 5-10Kg/h, 10-30Kg/h, 100-1000Kg/h (speed adjustable)
Small screw conveyor is a small diameter screw conveyor, also known as a micro-screw conveyor, with a screw diameter of 100mm-159mm, a length (centre distance between import and export) of generally 100mm-2000mm, and a conveying capacity of 0.01kg/h-1000kg/ h, designed for small feeding speed and laboratory applications, usually used in the production of chemicals and pharmaceuticals or any process that requires precise small-volume delivery, by continuing to feed the material into the main feeder after it is closed Below the outlet of the larger main screw feeder to improve feeding accuracy.
Small screw conveyors can be used for uniform and continuous feeding and unloading of small batches of powders and granules in laboratories and small batching plants. They are usually installed in silos, below the main screw feeder, and feed small quantities accurately.

1.Small diameter - the contact parts of the whole machine and the material are all made of 201 stainless steel, and the length design range is 1 meter to 12 meters, which can be customized according to the customer's materials and requirements. The minimum feeding pipe diameter is more than 114MM, and the conveying capacity per hour is at least 800KG. Spindle motor power is determined according to customer requirements and material selection.
2.Stainless steel - The distance between the inner wall of the stainless steel feeding tube and the spiral blade is not more than 3mm, the spiral blade is laser-cut, and all welding ports are polished to achieve smoothness without residue.
3.Small amount of discharge - The conveying speed of the small screw conveyor is from 100KG to 15 tons per hour.
4. No dust - The imported universal bearing is heat-insulated and dust-proof, and the two ends of the feeder are designed and installed with oil seals imported from Taiwan to ensure that dust and sundries enter the bearing to achieve the purpose of durability.
5.Scientific design - The screw shaft is made of stainless steel seamless tube, which is corrected by a lathe to ensure concentricity and stable operation of the machine. The blades are all made of stainless steel, and the blades are made of thickened stainless steel blades.
6. Automatically remove residual material - The bottom is designed with a clearing port. If you need to change the material, you only need to blow it down with an air gun to remove a small part of the residual material. And a safety switch is designed at the clearing port. Once the clearing door is opened, the power will be cut off, which is safe and reliable.
7. Overload protection - The circuit is designed for overload protection, which effectively protects the motor from burning and is durable. It has the function of stopping when the material is full, and the material is not automatically drawn. Just set the material time, no need for workers to take care of it.
