Chinese wholesale Flexible Screw Conveyor - Maize starch powder airflow centrifugal vibrating screen sieving – Trufiner

Working principle

Horizontal airflow sieve is also called horizontal airflow sieve. It is suitable for sieving ultrafine powder and special materials with light specific gravity, high viscosity, many fibers, static electricity and easy agglomeration within 80-530 mesh.

The screen of the horizontal airflow screen is cylindrical and placed in the body. After the material passes through the screw conveying system, it is mixed with the air flow and atomized into the mesh cylinder; , so that the material is sprayed through the net and discharged from the fine material discharge port, and the material that cannot pass through the net is discharged from the coarse material discharge port along the wall of the net cylinder. Accuracy and so on.

Product advantages 

● Both powder and granule are applicable. Small footprint, stable and no vibration, no noise in operation, good airtight performance, and no environmental pollution.

● It can be matched with single machine or multi-machine, three-dimensional multi-layer installation, flexible and convenient movement, safe and reliable continuous operation.

● High sieving accuracy, suitable for sieving ultrafine powder, low density (light specific gravity), slight humidity, easy to stick to sticky powder or materials with electrostatic reaction

● .The screen mesh has a long service life, the internal structure is novel and advanced, and the mesh frame design is unique and durable. It is easy to change the net and the operation is simple. The fiber screen pipe or stainless steel screen pipe is fixed with ring clamps and long strip clamps.

● .It has free shaking net, automatic cleaning, function of crushing block materials, and high screening efficiency.

● The airflow screen is easy to clean, suitable for screening of various varieties and small batches, avoiding cross-contamination of materials caused by mixing.

● The air sieve connected in series in the air duct system can withstand the pressure of 0.1MPA, which is suitable for positive pressure systems such as flour, and has a large sieving output.

Installation, operation and debugging of horizontal airflow screen：

1. After the horizontal airflow screen equipment is transported for a long time, all the fastening bolts should be checked and tightened. When the screen machine is hoisted and moved to a fixed position, it should be noted that the screen machine is in a horizontal position as a whole. Otherwise, it will affect the normal operation of the screen machine.

2. There is no special requirement for the equipment foundation, generally it can be used directly on the cement floor.

3. The connection between the purified compressed air and the air filter joint is connected with a pressure-resistant (P=0.1MPa) hose.

4. The connection method of the horizontal airflow screen and other equipment is softly connected by threaded rubber hose, coarse cloth and synthetic fiber pipe, and can also be directly connected with the pipeline.

5. Before starting the sieve machine, check whether the end cover, observation hole, and each connection part are loose, and whether each connection interface is well sealed.
