Structural composition
The cement fineness negative pressure sieve analyzer is mainly composed of sieve base, micro motor, dust collector, cyclone and electrical control.
instructions
1. before sieving test, adjust the digital explicit time relay, set it at 120s, put the negative pressure sieve on the screen seat, cover the sieve cover, turn on the power supply, adjust the negative pressure to -4000~-6000pa range, then turn off the machine.
2. Weigh 25g of sample, put it into a clean negative pressure screen, cover the screen cover, start the instrument again and screen continuously. During this period, if a sample is attached to the screen cover, tap the screen cover gently to make the sample fall. When the screen is full for 120s, the instrument will stop automatically.
3. After screening, weigh the residue with a balance
matters needing attention
1. Regularly pour out the cement in the dust collecting bottle.
2. If the negative pressure cannot meet the requirements of the national standard (- 4000 ~ - 6000pa) after using for a period of time, please clean the dust collection bag in the vacuum cleaner.
3. The vacuum cleaner shall not work continuously for more than 15 minutes, otherwise it is easy to overheat and burn out.

1.The pressure screen basket is composed of a sieve perforated plate, an overflow bucket and a non-perforated plate. 2. There are many small holes distributed on the screen plate, and the vapor passes through the small holes from bottom to top, transfers heat and mass through the liquid layer on the tray, and then rises. 3. The liquid flows through the tray according to a certain route, and the liquid is held by the vapor with a stable flow rate, and flows through the overflow hopper to the non-porous plate (liquid receiving tray) of the next tray. 4. The thickness of the liquid layer is determined by the height of the inlet baffle and outlet baffle on the tray.
Paper Mill Outflow Pressure Screen/Coarse Screen/Fine Pressure Screen Used for fine screening waste pulp and all kinds of coarse and fine pulp. 1. The rotor is rotated outside of the sieve drum, and the heavy impurities flow away from the sieve drum to avoid clogging the screen cut and prolong greatly the service life of sieve drum. 2. It has low pulse, high screening efficiency and reliable operation. Features: This equipment can be fitted with energy-saving rotors: coarse screening. Rotor, fine screening rotor and headbox screening rotor. Corresponding shell body and screen cylinder can match each Different rotor, thereby achieving screening different pulp kinds with High screening efficiency and low power consumption.
