The rigid impeller feeder machine is used to continuously and evenly convey the dry powder or small particle materials in the upper silo to the next level of equipment. It is an accurate quantitative feeding equipment. The rigid impeller feeder is specially designed for continuous and uniform conveying of dust, coal powder and other dry materials with a particle size of less than 10 mm. Its characteristics include excellent blade wear resistance, efficient air locking performance, thorough discharge, smooth connection and compact structure. The elastic impeller feeder adopts an elastic rotor to further improve the sealing performance and ensure uniform feeding of materials.

Rigid impeller feeders are suitable for conveying and batching systems in power plants, cement plants, chemical plants and other industries. They are used for air locking or quantitative feeding when conveying dry powdered materials. They can also be used for ash discharge under the ash hopper of dust collectors and air preheaters. They have simple structure, stable performance, and convenient operation and maintenance. They are ideal supporting parts in conveying, unloading and batching systems.

Structures and Working Principle

When the impeller It consists of a rotor with several blades, a housing, a seal, a motor, a reducer, etc.

It is driven by the transmission mechanism to rotate in the machine body, the powder and particle materials dropped from the upper separator (or hopper) enter the impeller cell from the feed port and are sent to the discharge port for discharge as the impeller rotates. In the whole working process, the materials can be fed and discharged continuously and quantitatively.

Features

  • Flexible impellers are used for smooth operation and good sealing.
  • The sealing device and gears are reliable and can be configured according to customer needs.
  • Two and a half sealing rings are used at both ends of the impeller, which has a simple structure and is easy to install and replace.
  • The discharge port can be designed into different styles such as square or round according to user needs.
  • The bearings at both ends of the equipment are designed outside the machine body, which effectively prevents dust from entering the bearings, reduces wear and extends service life.

Application

Stainless steel impeller feeders are widely used, covering multiple industries such as chemical, pharmaceutical, food, and metallurgy. It can not only convey powdered raw materials, but also is suitable for conveying granular materials.

  • In the chemical industry, this equipment is often used to convey various chemical raw materials, such as granular plastics and alumina powder.
  • In the food industry, it is used to convey various food raw materials such as flour and rice noodles to ensure the efficiency and hygiene of food production.
  • In the pharmaceutical field, stainless steel impeller feeders can safely convey various drug raw materials to ensure the hygiene and safety of the production process.
  • In the metallurgical industry, stainless steel impeller feeders can convey various metal particles, such as iron powder and copper ore, to meet the high-strength and wear-resistant conveying requirements.

FAQS

Installation precautions

The impeller feeder should be cleaned during installation, especially there should be no foreign matter in the shell. Check all fasteners to ensure reliable connection and good grounding. The upper and lower flanges of the entire impeller feeder must be firmly connected, and check whether the whole machine is level.

Operation precautions

If the motor heats up at the beginning of work, it should be stopped and checked immediately. The operation should be carried out in accordance with the instructions of this impeller feeder. If powder leakage occurs during operation, the packing gland bolts at both ends should be tightened. Pay attention to the temperature at the bearing, which should generally not exceed 60℃. If any abnormality is found during use, stop the machine immediately for inspection.
