Vibrating sieve machine includes eccentric ring vibrating screen, inertia vibrating screen and resonance vibrating screen, etc., their common characteristics are high vibration frequency of the screen surface, small vibration, so that the material on the screen surface is separated, the screen hole is not easy to plug, high screening efficiency, simple structure, light weight, low power consumption, can screen viscous or wet materials, widely used. When the raw material contains clay, silt or other impurities, it can also be washed with pressure water on the screening machine for wet screening.
Eccentric ring moving screen amplitude does not change with the amount of material on the screen, suitable for the first rough screen, the mesh is generally 13 ~ 100mm, up to 100 ~ 250mm. The maximum feed particle size can reach 300 mm, inertia vibrating screen has a single axis and two axis vibration system, the vibration system movement and the weight of the material and the stiffness of the spring, so the increase or decrease of the screen surface material directly affects the amplitude, suitable for the feed amount and particle size change is not large occasions, often used in the secondary screening of aggregate, the mesh number is 0.5-100 mm, The maximum feed particle size is 100-500 mm, the screen box of the resonance screen works under resonance conditions, only the supply of energy to overcome the damping of the screening movement can work continuously, less power consumption, suitable for the screening of medium and fine stone, the mesh number is 0.5 ~ 80mm, and the maximum feed particle size is 100mm.
Safe operation procedure of vibrating powder sifter:
First, the preparatory work before starting:
1, before entering the dust workplace, you must wear labor protection supplies according to regulations;
2. Check and open indoor ventilation facilities;
3. Open the protective isolation cover of the sifting area and check whether the isolation cover is intact;
4. Turn on the vacuum cleaner and check whether it works properly.
2. Operation guide:
1, open the bottom screen frame, clean the bottom screen frame screen;
2, install the screen screen, tighten the bottom screen frame, tighten the screws;
3. Connect the powder outlet of the bottom screen frame with a plastic bag, and tie the plastic bag with a tape rope;
4. Start the machine and add the toner to be screened into the powder inlet;
5. After sifting the powder, stop the machine, take out the sifted toner, and bag it.
Iii. Preventive Measures:
1, when engaged in dust operations, pay attention to the operation method to prevent dust flying;
2, carefully check the sealing equipment to prevent dust leakage;
3. Dust working places should be cleaned regularly and kept clean;
4. When engaged in dust operations, pay attention to wearing dust masks to avoid inhaling dust and prevent the occurrence of lung diseases;
5. Eating and smoking are strictly prohibited in dust workplaces;
6, the dust collector should often check its exhaust performance, and implement maintenance checks.
Advantages of vibrating powder sifter:
1, due to the strong vibration of the screen box, the phenomenon of material blocking the screen hole is reduced, so that the screen has higher screening efficiency and productivity;
2, vibrating screen high efficiency, light weight, complete and diverse series, multi-level, can meet the needs of screening dry materials;
3, simple structure, screen surface disassembly and replacement is convenient;
4, less power consumption per ton of material screening.
