During rolling process many small powders adhered to the surface of the rollers which needs to be cleaned. The cleanliness of the rollers is necessary for preventing foreign particles from penetrating the substrate material. Roller brush is generally used for cleaning.
In the process, there can be 4 small processes need dust removal:
2.1 Dust removal for pole piece before rolling: the upper and lower two sides of the pole piece material need to be equipped with a multi-point recycling collection system. Set 2pcs dia50mm air inlet on the cover of the brush (Confluence is about φ100mm), since the amount of dust is limited, VJ or model with higher configuration can solve the dust problem well, and explosion-proof requirements are considered in due course.
Model can be selected:
Manual cleaning type VJ-H series dust collector
Self-cleaning type VJF series dust collector
VJFGB explosion type dust collector
2.2 Dust removal for corner cutting: each cutter has a diameter of about φ40, ranging from 2 to 4 (commonly 4 scrapers — 2 for each of the upper and lower rollers). After being put together, the φ75 suction port is enough for dust removal on this position. The suction hood is only equipped on the side of the discharge port, and the diameter of each suction hood is φ75. The cutter dust suction hood is shown in Figure 2.3.3-b, the hood for scrap material suction is under the knife, as shown in Figure 2.5.3-1, and the VMQ system for supporting material receiver is shown in Figure 2.5.3-3, or Figure 2.5.3-4.
Model can be selected:
VMQ receiving machine
2.3 Roller dust removal: Dust collector with hood is the ideal option for the dust generated by the upper and lower roller scrapers. The diameter of each blade hood depends on the length of the roller, and set multiple suction openings will be gathered into a total dust suction port (commonly φ73mm or φ110mm) The scraper suction hood is shown in Figure 2.3.3-c.
Models can be selected:
VJ-H series manual cleaning dust collector
VJF series automatic cleaning dust collector
VJFG series dust collector
VJFGB explosion proof dust collector (Contact us for proposal making)
2.4 Belt-connecting platform: 20-25mm dust extraction pipe cover will be equipped underneath, sharing a main machine with 2.1) & 2.3).
