Graphite powder feeder/powder feeding machine/vacuum conveyor
Working principle:
EVC series pneumatic vacuum conveying system, which usually consists of feed station, soft tube, separator tank (or Three-way valve), secondary filter and high pressure air pump, is the ideal method for conveying or moving bulk materials, such as free-flowing powder and granules, from place to place within a factory by using pneumatic suction.
The high pressure air pump generates strong air flow inside the conveying system. Air rushes in through the suction inlet of feeding point, where bulk material is carried in this air stream. Then the bulk material is conveyed into the separator tank (or three-way valve) with the air stream, which separate most of the bulk material from the air and discharge it into the delivery point. The air with small quantity of fine powder flows through the secondary filter and is exhausted by the air pump.
Two types of conveying system are available depends on different receiving hoppers:
Type A: Conveying to sealed hopper. The hopper should be air-tight and a three-way valve for separating bulk material from air has to be inserted into the hopper. The conveying process is continuous.
Type B: Conveying to top-open hopper. The separator tank, usually includes filter, flap valve and air shock tank, should be mounted above the hopper. When the separator tank is filled with bulk material, the air pump switches off automatically. Meanwhile, the air shock tank release the compressed air from inside of filter to blow off the fine particles and the flap valve opens to discharge the bulk materail into the beneath hopper. The system often operates based on timed interval. If air locker (air tight rotary valve) is equipped, the operation can be continuous.

Product Structure



Technical advantages:
1. Dust free transfer of bulk materials: Negative pressure inside the conveying system and two-stage filter can create dust free condition
2. Easy to clean: The conveying system can be easily dismantled for cleaning
3. Small foot print: The conveying soft tube takes up little or no floor space within your facility
4. Easy to install: The conveying system is connected by quick-open clamps which makes the installation very easy
5. GMP standatrd: The system is made by stainless steel and mirror polished. No dead corners for cleaning.
6. Low noise and power consumption: Noise in operation is less than 60 dB.
FAQ:
Q:What factors I need to get a quotation?
A: Name of materials;Capacity per hour;The bulk density of the material;Conveying distance and height;Voltage & Frequency(Hz).
Q:What is the real delivery time of your factory?
A: 7 to 15 days for general series products, meanwhile, batches products & customized products would need 30 days to 60 days basedon different situations.
Q: How do your after-sale service work if the product got damaged?
A: In the guarantee time 12 months, our general after-sale service is changing the damaged parts for the customer, but if the damage could be repaired by slight cost, we wouldwait for the customer's bill for the fix cost and refound this part of cost.(note: Vulnerable parts do not include.)
