Product Overview
The FM vibration-type screen (also known as the Somerville-type vibrating screen) is designed and manufactured in accordance with the TAPPI 275 standard. It is used to screen impurities in pulp, determine the content of debris and other impurities in the pulp, and reduce the quantity of impurities in the pulp suspension that do not meet process requirements, thereby obtaining clean and acceptable pulp.
Product Features
1. Compact size, easy to operate, and space-saving.
2. Adjustable vibration frequency, allowing different frequencies to be selected based on the slurry for optimal results, wider screening range, and providing reliable experimental data for production.
3. Simple screen plate removal, convenient operation, and compatibility with various types of screen plates.
Working Principle
Vibratory vacuum suction is applied to the prepared pulp. The speed-regulating reducer drives the cam to vibrate the bottom plate up and down via a connecting shaft, generating high-frequency vibrations in the pulp. Qualified pulp passes through the screen slots, while unqualified fibers and debris remain on the screen plate, thereby screening the pulp fibers. The machine is equipped with a slotted screen as standard and can also be configured with round-hole screens to function as a flat screen. The purpose of screening is to separate impurities such as shives from mechanical pulp, as well as large contaminants, plastics, sand, iron filings, and flakes in recycled pulp fibers, followed by inspection and quantification.
Application areas
Pulp screening, determination of impurity content, fiber selection.
Compliant with standards
TAPPI275
Operating Steps
1. Pour the prepared pulp into the screen.
2. Set and adjust the vibration frequency to suit the pulp.
3. Start the machine for high-frequency vibration screening.
4. Collect the accepted pulp passing through the screen slots and dispose of the impurities retained on the screen plate.
Precautions
- Ensure the sieve plate is installed correctly before operation.
- Select the appropriate vibration frequency based on the slurry type.
- Regularly inspect the sieve plate for damage and replace it promptly.
- Pay attention to safety during operation and avoid contact with moving parts.
