Screw Feeder

The screw feeder can convey powders and granules from one machine to another. It can be combined with the packaging machine to form a production line. It is mainly used for conveying powdered materials, such as milk powder, protein powder, rice flour, milk tea powder, solid beverages, coffee powder, sugar, glucose powder, food additives, feed, pharmaceutical raw materials, pesticides, dyes, flavors, spices, etc.

Product Introduction

Principle Introduction

The material weight signal from the metering screw is transmitted to the 3U403 (one machine with one DCS interface) or 3U600 (one machine with 16 channels) measurement and control system (both 3U403 and 3U600 have a microprocessor at the core). By continuously comparing the set value with the actual weight of the material conveyed by the screw, the speed of the steady flow spiral is constantly adjusted. As a result, the material flow is always stable at the set value.

• Automatic feeding
• All stainless steel construction, full welding and polishing
• Quick-release barrel for easy maintenance and cleaning
• Spiral reversal and bottom scrap outlet, easy to clean
• The hopper can be vibrated or stirred

Structural features

• The connection between the screw shaft and the hanging bearing, the head and tail shaft are embedded in the tongue type, and the installation and disassembly do not need to move axially, and the maintenance is convenient. The mandrel is long, the hanging is less, and the fault point is less.
• The variable diameter structure is adopted to increase the volume of the hanging bearing to avoid contact between the lifting bearing and the material, and the life of the lifting bearing can reach more than two years.
• Each transmission part adopts a floating connection mode, and the crane bearing is a universal joint structure, so that the spiral body, the crane bearing and the tail assembly form an integral rotary float body, which can be freely rotated and avoided with the conveying resistance within a certain range, without jamming or blocking.
• The head and tail bearing seats are outside the shell, and all bearings adopt multi-layer sealing and matching sealing technology, so that the bearing has a long service life.
• Compared with other conveying equipment, the screw feeder has the advantages of small cross-sectional size, good sealing performance, stable and reliable operation, multi-point loading and unloading in the middle, safe operation and easy maintenance.

The bulk bag discharger is suitable for unloading bagged powder and granular materials. It is widely used in industries such as food, pharmaceuticals, advanced materials, battery materials, and metal powders.
