Product Details
Environmentally Cement fineness negative pressure sieve analyzer FSY-150B
1. Product Overview
The FSY-150B cement fineness negative pressure sieve analyzer is a laboratory equipment used to determine the fineness of powder materials such as cement and fly ash. It is designed according to the national standard GB/T 1345-2005 "Method for Testing Cement Fineness" and uses negative pressure sieve method to quickly determine the sieve residue of the sample, thereby evaluating the fineness of the powder particles.

3. Instrument features
- High precision screening: using negative pressure screening principle to avoid manual errors and achieve good repeatability of results.
- Automatic control: Built in timer, automatically stops screening and analysis, easy to operate.
- Low noise design: Optimized fan structure, working noise less than 75dB.
- Good sealing: Transparent sealed screen cover to prevent dust from overflowing and protect the experimental environment.
- Easy maintenance: The screen mesh can be disassembled and replaced, and the instrument structure is easy to clean.
4. Operation steps
- Preparation: Check if the sieve is intact, turn on the power, and adjust the negative pressure to the standard value (such as 5000Pa).
- Sample weighing: Accurately weigh 25g of cement sample (accurate to 0.01g).
- Screening process: Pour the sample into the sieve, cover it with the sieve cover, start the instrument, and automatically screen for 2 minutes.
- Result calculation: After screening, weigh the mass of the residue and calculate the percentage of residue (formula: residue/total sample amount x 100%).
5. Precautions
- Regularly check whether the screen mesh is blocked or damaged, and clean or replace it in a timely manner.
- After the experiment, turn off the power, clean the residual powder, and keep the instrument clean.
- If the negative pressure is insufficient, it is necessary to check whether the pipeline is leaking or whether the filter bag is blocked.
- The instrument should be placed on a stable and dry surface to avoid vibration.
6. Application Fields
- Quality control of cement production enterprises
- Building materials laboratory testing
- Fineness analysis of powder materials such as fly ash and mineral powder
