Date:2024/07/05
Main technical parameters
Rotary Drum Granulator as an important equipment in fertilizer production, its various models to meet the output needs of different users. The following table lists the main technical parameters of some models, including cylinder size, production capacity, weight and motor configuration, etc., to provide a detailed reference for users to purchase.
Installation and commissioning
First,Installation steps:
1. Basic preparation:
According to the process to determine the elevation and horizontal position, to ensure that the Rotary Drum Granulator inclined installation, tilt is generally 2-5 degrees, can be adjusted according to user needs. The bracket and transmission frame of the machine have ground holes, which can be installed on concrete.
2. Base adjustment:
Adjust the height of each base using a gate shape plate to ensure a consistent overall tilt. The total thickness of the water-shaped plate between the mechanical base and the foundation should not be greater than 30-35㎜.
① Adjust the height of each base with the water-shaped backing plate to make each bottom tilt 5 degrees;
② The adjustment of each base is suitable for placing the cylinder on the support, and finally adjusting the support wheel;
③ Adjustment method of body position:
a. On the full length of the left and right sides of the body, install two parallel steel wires, the diameter of the steel wire is 0.5-1㎜ and check the level of the steel wire with a level instrument;
b. From each circle along the sides of the dryer, put down two phase hammers that are tangent to the circle;
c. Measure the distance between the wire and the drop to detect the body in the horizontal position;
d. Detect the relative vertical elevation of the two highest points of the circle to check the position of the body on the vertical plane;
e. Adjust the measurement of “c”and “d” by means of moving electric support wheel to make the body in the correct position;
3. Transmission installation:
Install the transmission part of the pelletizer to ensure that the transmission device fits well with the cylinder.
4. Casting fixed:
After confirming that the support wheel, transmission device and cylinder are adjusted properly, the cement is poured, and after 8-10 days, the no-load test is carried out after the cement sets.
Second, No-load test:
a. Temperature monitoring: for 8 hours without load at different breaks, the monitoring bearing temperature should rise steadily, and the bearing temperature should not be higher than 50℃ at the end of the test run.
b. Noise check: gear noise should be uniform, no abnormal fluctuations.
c. Wear check: Check whether the bearing has serious wear or abrasion after the test.
Associate devices and technologies
Chain Crusher: In the raw material treatment stage, the chain mill can be used to crush large pieces of material into a particle size suitable for granulation, ensuring the smooth operation of the Rotary Drum Granulator.
Drum Screener Machine(Rotary Screener Machine): In the screening process after granulation, the roller screen can effectively separate particles of different sizes to ensure product quality.
