Product Overview
The working principle of a single cone screw dryer is that the rapid rotation of two asymmetric spirals inside the mixer cylinder lifts the material upwards, forming two asymmetric spiral shaped material flows along the cylinder wall from bottom to top. The spiral revolution motion driven by the rotating arm causes the material outside the spiral to enter the spiral envelope to varying degrees. Some of the material is displaced and lifted, while the other part is thrown out of the spiral, thus achieving continuous updating and diffusion of the material in the circumferential direction. The two streams of material lifted to the upper part then converge towards the central cavity, forming a downward material flow that fills the cavity at the bottom, thus forming a convective cycle. Due to the combination of the above movements, the material was uniformly mixed in a short period of time with high mixing accuracy.
The machine can add a jacket outside the mixer cylinder according to process requirements, and cool or heat the material by injecting cold and hot media into the jacket; Cooling is usually pumped into industrial water, while heating can be done by introducing steam or electrically heated heat transfer oil.
Characteristics of single cone screw dryer equipment
1. The structure is simple and reasonable, and the operation is convenient. The spiral shaft is connected to the barrel cover, and there is no bearing at the bottom, avoiding faults caused by powder leakage from the bottom bearing;
2. The mixing efficiency is high and uniform. The double helix of this machine is arranged asymmetrically, with one long and one short for comprehensive mixing. Therefore, it is more suitable for mixing materials with different densities and special mixing combinations;
3. Compared with the drum mixer, this machine consumes only about one tenth of its energy, indicating a significant energy-saving effect;
4. The mixing process is gentle and will not cause damage to granular objects;
5. Closed production, dust-free and conducive to working environment. Long service life, and according to user requirements, the cone can be made into a pressure vessel for pressurization and vacuum operation.
