Features of the products that Bunri handles

Microfiltration Filter Conveyor BAL

Cited from: https://www.bunri.com/product/bal/

Bunri's BAL microfiltration filter conveyor is a product with a filtration system as high as 20 μm 90% or more. Therefore, there is no need for 22nd stage treatment and it is compatible with high-pressure pumps up to 3 Mpa. The filter uses a tear-resistant, highly rigid sintered material filter.

No cartridges or other consumables are used, so there is no industrial waste discharge. Chips are discharged in a liquid cut state, reducing the discharge of coolant along with the chips. This product is suitable for processing non-magnetic cutting chips.

Rolling filter conveyor MAL

Rolling Filter Conveyor MAL can handle magnetic and non-magnetic chips and is suitable for processing both in one machine. The perforated filter rotates in contact with the rake plate, and automatic cleaning prevents clogging.

Filtration accuracy is 200 µm, 90% or better. No mist is generated without backwashing, which will help improve the environment in the factory. No cartridge filters, paper filters, etc. are used, which helps reduce industrial waste and costs.

Cyclone filter Dust catch

Cited from: https://www.grow-ing.net/ダスキャッチ

Growing's cyclone filter DusCatch separates sludge particles by centrifugal force using pump power. Separated sludge is collected in the periphery, precipitates downward, and is discharged from the drain section. Clean liquid from which sludge has been removed collects in the center.

A self-contained pump is included, and filtration occurs automatically when the hose is fed into an existing facility and the power is turned on. It can be installed in existing facilities and is equipped with casters for easy installation and transportation.

Paper Filter Series

Cited from: https://www.shi-ftec.co.jp/products

The paper filter series from SHI FINETECH cleans coolant liquid using filter paper. Depending on the filter paper used, filtration is possible for particles with an average size ranging from 10 μ to 95 μ. When the filter paper becomes clogged, a new filter paper is automatically supplied to the machine to improve work efficiency.

FINECLONE.

Adverse effects of aluminum sludge

Rust formation

One of the adverse effects of aluminum sludge is rust. Rust requires special attention when processing workpieces made of steel materials, but aluminum sludge also rusts depending on the environment.

Sludge during material processing can cause aluminum rust. One of the reasons for aluminum rust is the deterioration of coolant fluid. As coolant fluid deteriorates, it tends to turn from alkaline to acidic, making aluminum more susceptible to rust.

Rust is also likely to occur when multiple materials are processed on a single machine. When sludge is retained, such as after processing rust-prone steel, it mixes with the coolant solution and adheres to the material, causing rust to form.

Rust is caused by coolant fluid, so if fine sludge or suspended sludge is seen, it should be collected promptly to reduce rust.

Generation of bad odor

Aluminum can be contained in floating oil as floating sludge. If sludge in floating oil is left unattended, it is more likely to decompose and emit foul odors.

If the coolant fluid is not exposed to air due to floating oil, bacteria will proliferate significantly, lowering the PH and causing foul odors. If not managed properly, coolant fluid will decompose, so action must be taken before bad odors occur.

One solution is to change the coolant fluid to one that is odor- and corrosion-resistant. If it is difficult to change the coolant fluid, make sure that the coolant is being properly managed. If foreign substances such as sludge are mixed in and remain in the coolant, promptly removing them will prevent the coolant from becoming rancid.

Coolant filtration system
Three recommendations

Coolant filtration equipment is used to filter sludge generated from equipment. There are a variety of products available depending on the intended use, so it is important to determine "whether the coolant filtration equipment is suitable for the purpose" and "whether the equipment is suited to the characteristics of sludge.
