Chip Disk Filtration (CDF): How It Works

Product catalog summary

Continuous Self-Cleaning Operation
The system features self-cleaning permanent media with accessible spray nozzles that provide a continuous backwash spray. This mechanism effectively removes fines and chips, preventing gunky build-up on the disc. Notably, it operates without external sources like air or steam, unlike traditional drum filters where nozzles are mounted inside the drum, making them hard to access.

Dual Stage Filtration with a Single Belt
The CDF technology offers high filtration levels using a single belt, thanks to a patented disc design that directs coolant flow into the reservoir. It filters various materials in both water and oil-based coolants down to 25 microns nominal, using either a hinge or scraper belt. This contrasts with other designs that require both a hinge and scraper belt for fine filtration.

Chip-Disc Filtration (CDF)
The patented disc filtration design ensures a direct coolant flow path into the tank reservoir, efficiently filtering a wide range of materials in different coolant types.

Coarse Chip Removal
A hinge or scraper belt collects larger chips and particles, discharging them into a chip hopper. This pre-removal of coarse chips prevents system jamming and enhances fine particle filtration efficiency.

Fine Particle Filtration
1. Small particles that bypass the belt follow the coolant flow to the rotating disc filter.
2. Particles are collected, and cleaned coolant returns to the tank. The particles rotate with the disc filter and are lifted towards the backwash spray.
3. The backwash spray blasts particles onto the belt, removing them along with coarse chips.

Chip-Disc Filtration: How It Works
The document outlines the process of chip-disc filtration, emphasizing the efficiency and innovation of the system in handling both coarse and fine particles.

Chip Disk Filtration (CDF): How It Works-1

CHIP-DISC FILTRATION (CDF) PATENTED DISC FILTRATION DESIGN Our innovative design provides a direct coolant flow path into the coolant tank reservoir, and filters a wide variety of materials both in water and oil based coolants. DUAL STAGE FILTRATION WITH A SINGLE BELT CONTINUOUS SELF CLEANING OPERATION Our CDF technology achieves high levels of filtration without two separate belts. Our patented disc design provides a direct coolant flow path into the coolant reservoir and can filter a wide variety of materials, both in water and oil based coolant, down to 25 microns nominal, using a hinge OR a scraper belt. Self-cleaning permanent media with easy-to-access spray nozzles provide a continuous backwash spray that removes fines and chips, keeping the disc free from gunky build-up. No outside source such as air or steam is used. Other drum filter designs use a hinge belt AND a scraper belt for fines. Drum filters typically have nozzles mounted on a pipe inside the drum which makes them difficult to access. 9900 North Alpine Road, Machesney Park, IL 61115 | 815.636.9900 | [email protected] | hennigworldwide.com

CHIP-DISC FILTRATION: HOW IT WORKS COARSE CHIP REMOVAL The hinge (or scraper) belt collects larger chips and particles for discharge into the chip hopper. Removing coarse chips before they reach disc filter keeps them from bundling and jamming the system, which fosters extremely efficient fine particle filtration. FINE PARTICLE FILTRATION ❶ Small particles that escape the belt naturally migrate with the coolant flow to the rotating disc filter. ❷ There, particles are collected and the cleaned coolant flows back into your tank. The collected particles rotate with the disc filter and are lifted...
