Working principle

The working principle of the screw feeder hopper is based on the ingenious combination of the screw body and the spiral groove, forming a tight conveying system in the pipeline. When the motor starts and drives the screw body to rotate, the spiral groove rotates synchronously with the material and pushes forward under the action of centrifugal force, thereby realizing continuous and stable conveying of materials.

Working Process

When the screw feeder with hopper is running, the motor drives the screw body to rotate rapidly in the pipeline through the transmission reducer, thereby realizing efficient transportation, precise unloading, and effective processing of materials. The material is injected into the system from the feed port. With the rotation of the screw, it is gradually transported to the discharge port and discharged smoothly after a precise unloading procedure.

Types of Screw Feeder Hopper

Vibrating screw feeders are available in a variety of customizable models. In terms of material, it is mainly divided into two types: stainless steel and carbon steel. In terms of tilt angle, vibrating screw feeders can be divided into horizontal, tilted, and vertical types according to the degree of tilt. In addition, to meet different production needs, buckets of different shapes can also be selected, such as no bucket, square bucket, round bucket, etc.

Stainless Steel Screw Feeder Hopper

It is mostly used in industries such as food and medicine that have high requirements for a hygienic environment. It is resistant to acid, corrosion, wear, and rust. It is also more convenient to clean up after use.

Carbon Steel Screw Feeder Hopper

Carbon Steel Screw Feeder Hopper

It is used in industries where hygiene requirements are not very strict, with low cost, large conveying capacity, good heat insulation effect, no cooling device, and low power consumption.

Screw Feeder Hopper

Horizontal Screw Feeder Hopper

It is used for continuous and uniform conveying of loose materials horizontally or slightly inclined (below 20º), and the conveying distance is generally not more than 70 meters.

Screw Feeder Hopper

Inclined Screw Feeder Hopper

It is used for conveying materials within a range of 60°, and the conveying length can reach 60 meters. It can convey and lift products at the same time, and can directly and automatically convey powder or granular plastic raw materials to silos or other equipment.

Vertical Screw Feeder Hopper

90° vertical upward conveying of materials, the speed is higher than that of ordinary screw conveyors, the lifting height is generally not more than 8 meters, and the floor area is small.

Features of screw feeder hopper 

  1. The feeding is uniform, and the feeding speed can be controlled by installing a variable frequency motor, and the material is not easy to be blocked.
  2. The feeding motor and the vibration motor can be switched separately to control the vibration amplitude. The system has a time relay. Set the time according to the set amount each time to control the feeding amount.
  3. The direction of conveying materials is reversible, and materials can be conveyed in two directions at the same time. During the conveying process, mixing, stirring, loosening, heating and cooling can also be completed.
  4. The silo and conveying pipe are made of stainless steel (the material can be customized according to customer requirements) to ensure that the raw materials are completely pollution-free during the transportation process. 5. The conveying pipeline adopts a closed design, which can effectively prevent dust and effectively isolate materials with high hygiene requirements or strong odor.

Structure

The screw feeder hopper consists of a discharge device, a precisely designed screw shaft, an efficient feeding mechanism, a sturdy transmission, and other components.

  • Vibration motor: The feed motor and vibration motor can be switched separately, and the feeder and vibration amplitude can be independently controlled. The time relay is seamlessly integrated into the system, and the precise time adjustment can be made according to the specific batch size to control the feeding amount.
  • Hopper: The design of the hopper should consider reducing the pressure of the feeding screw, and a pressure relief mechanism can be added if necessary to improve the feeding accuracy. Round or square hoppers can be selected for easy feeding. It can be used alone or directly connected to its supporting equipment.

Screw Feeder with Hopper

The screw feeder with hopper is a uniform feeding device based on the principle of the screw conveyor. The device can easily realize the uniform supply of non-sticky powder, granular, and small particle materials from silos and other storage equipment, and the feed particle size is less than 5mm.

Screw feeder with hopper combines conveying, sealing, homogenizing, mixing, and other functions in one, widely used in cement raw material homogenization and silo sealing feeding. It has the advantages of uniform feeding, good sealing, no dust, etc. In addition, the closed design of the conveying pipe of the screw feeder can effectively prevent dust, and effectively isolate the materials with high hygiene requirements or strong odors to ensure that the raw materials are completely free of pollution in the conveying process.

1. Selection of Appropriate Model According to Different Production Requirements

For conveying with slight inclination, horizontal orientation, or short distances, the horizontal screw feeder is suitable. Conversely, for vertical conveying or conveying at high inclinations with limited height, the vertical screw feeder is recommended.

Determination of Screw Blade Form Based on Conveyed Material

  • Solid Screw Blades: Primarily used for conveying dry, low-viscosity fine particles or powders such as lime powder, coal powder, etc.
  • Ribbon Screw Blades: Ideal for conveying materials with moderate viscosity or in block form, such as sludge.
  • Paddle Screw Blades: Designed for conveying materials with toughness or compressibility.
spiral shaft

According to the requirements of the process equipment, determine the rotation direction of the spiral blade, the spiral shaft and the direction of rotation, and the combination of the spiral body

The material conveying direction can be determined by determining the position of the conveyor head and tail. The rotation direction of the spiral blade and the direction of the shaft must meet the requirements. If unloading in the middle or at both ends, blades with different rotation directions should be combined to form a spiral body.
