Several methods for judging the quality of a twin-shaft mixer in fertilizer production line

The mixer is a machine that can mix a variety of raw materials to make it a mixture or a suitable consistency, and therefore plays an important role in fertilizer manufacturing process.

The two-axis mixer uses the synchronous rotation of two symmetrical spiral shafts to mix the powdered materials such as organic fertilizer compound fertilizer and water to uniformly humidify the organic fertilizer compound fertilizer powder material, so that the humidification material does not take dry ash. The purpose of water droplets will not ooze out, thus facilitating the transportation of humidified ash loading vehicles or transferring to other conveying equipment. It is mainly used in the case of humidification loading of fly ash or similar materials in industries such as organic fertilizer production process in organic fertilizer plants.


Working principle
1. The twin-shaft mixer is used for the pre-watering ball forming process.
2. When the quantitative raw meal powder flows into the stirred dough from the feed port, it is atomized by a certain amount of water to the raw meal powder, and the shaft of the qualitative length is stirred by the stirring blade to form a uniform core with water and transported to the pre-added water into a ball plate.
3. The whole agitation is divided into three areas: atomization area, mixing area and discharge area.
4. The double-axis mixer stirs the hard gold head on the blade, which has good wear resistance and long service life.

The horizontal mixer, the high peripheral speed of the stirring blade and the rotation trajectory of the blade, etc., the wear of the single-shaft mixer is larger than that of the twin-shaft mixer. Therefore, the maintenance cost is increased by using expensive special steel.
Here are a few ways to judge the quality of a two-axis mixer:
1. Check whether the bearings of the twin-shaft mixer are sealed and whether there is ash leakage;
2. Check the bearing belt of the twin-shaft mixer for looseness;
3. Check the speed reducer oil of the twin-shaft mixer, whether the manufacturer provides regular replacement;
4. Check the blade thickness of the twin-shaft mixer to meet the national requirements;
5. Check the spindle bearing of the twin-shaft mixer to see if it is new or has been rusted and aging;
