High frequency vibrating screen maintenance method:
1. When the equipment is in normal operation, the ore concentration of the sieve should be observed frequently to control the concentration to about 40% in order to improve the classification efficiency.
2. Because of the high classification efficiency of the sieve, the dewatering performance is good, and the concentration of the sieve is high, so that the slurry in the sieve amount chute is poor in fluidity, and the water pipe should be matched.
3, electromagnetic exciter and control box should be strictly protected against water, so as to avoid short circuit. The vibrator should be covered with a rubber plate to prevent water and slurry from falling into, causing a short circuit and blocking the air gap.
4. Check if the bolts in all parts are loose at any time, and whether the screen frame collides with the chute.
5. Attention should be paid to the current meter pointer not to exceed the value. When the screen machine is operated for about half a month, the current and current should be adjusted to a near value (generally 8-9A) for 4-5 minutes to shake off the back of the screen.
6. The excitation current (amplitude) can be adjusted according to the nature of the ore and the operation requirements. In order to make the sieve work under the high efficiency condition of Zui, the excitation current condition test can be performed.
7. After the sieve is used for 1 month, the sieve is removed, and the 180° U-turn is performed to enhance the "cutting" effect of the sieve to improve the classification efficiency.
8. When the slurry of the cloth bucket is too far into the sieve, the position or angle of the screen frame should be adjusted in time to avoid affecting the classification efficiency.
High frequency vibrating screen maintenance method
The high-frequency vibrating screen is mainly used for pre-grading and inspection grading of the second-stage grinding products of the second-stage grinding of magnetite mines. It can also be used as a closed circuit with the second-stage grinding operation. It is also widely used in coal mines, chemical industry, building materials, etc. industry. The following is mainly to explain the structural characteristics and maintenance methods of the high-frequency vibrating screen.
