Activated charcoal

活性炭 / Aktivkohle / 활성탄

Activated charcoal
Description of Final products

A material composed of porous carbon that has selective adsorption properties for specific substances, and has been chemically and/or physically treated (activated) to achieve high adsorption efficiency. The product is available in a wide variety of shapes, such as powder, granules, cylinders, honeycomb structures, and blocks.

Applications

Water purifiers, deodorization systems, food decolorization, organic solvent recovery systems, separation and purification equipment for industrial products, etc.

Manufacturing process

※This process is just one example, and the manufacturing methods vary by company.

Raw materials to be processed (coconut shells, wood chips, activating agents, etc.)
Kneading
The raw materials are kneaded under heating to induce a reaction.
課題

The kneading intensity must be controlled to obtain optimal formability, bulk density, and uniformity. Furthermore, wear resistance against carbon is required for all material-contact parts.

解決策

The twin-screw continuous kneader "KRC Kneader" enables control of kneading intensity to produce uniform and stable products, while also offering excellent durability and ease of maintenance, by the following mechanical characteristics.

KRCニーダ ジャケット加熱

Binder viscosity is maintained by heating the jacketed barrel.

KRCニーダ パドル回転

Kneading intensity is adjustable through paddle configuration and rotation speed.

KRCニーダ 耐摩耗材

Wetted parts are made of wear-resistant materials. And easy to replace.

Forming
The material is formed into the specified shape.
Calcining
The material is calcined at a specified temperature and for a specified time to decompose and volatilize organic and solid components in the raw material, thereby creating numerous pores.
Washing
The material is chemically washed to remove impurities.
Drying
The material is dried.
Grinding
Grinding is performed as necessary.
Classifying
Particles outside the specified particle size range are removed.
