Charcoal powder grading vibrating screen

What is a charcoal powder grading vibrating screen?

Charcoal powder grading vibrating screen is a high-performance device used to classify charcoal powder by particle size, remove impurities, and ensure product consistency through high-frequency vibration. Types include circular, ultrasonic, and linear vibrating screens. The vibrating screen operates at high speed, enabling precise grading of charcoal powder and ensuring consistent product quality across varying particle sizes.

The screen mesh size typically ranges from 20 to 400 mesh. The throughput varies depending on the model and number of screen layers. Small single-deck screens have a throughput of approximately 500 kg/hour, while large multi-deck screens can reach over 5 tons/hour. Materials available include carbon steel and stainless steel. The material contacting parts are typically constructed of 304 or 316 stainless steel. The frame can be made of either carbon steel or stainless steel, depending on the operating environment. The screen mesh is made of high-carbon steel or stainless steel woven mesh, ensuring wear resistance and precise screening.

Functions of Charcoal Powder Grading Vibrating Screens

The primary function of a charcoal powder grading vibrating screen is to grade charcoal powder, remove impurities, and improve product uniformity and added value. During charcoal powder production, uneven particle size distribution can affect subsequent processing, such as rod making, activation, tableting, or blending. Vibrating screening allows charcoal powder to be precisely graded by particle size, yielding powders in varying particle size ranges and improving the consistency of the finished product. Furthermore, this equipment removes foreign matter, lumps, dust, and impurities from the charcoal powder, ensuring product purity. Screening not only improves charcoal powder quality but also optimizes downstream process efficiency, reducing energy consumption and waste.

Charcoal Powder Grading Vibrating Screen Types

Circular vibrating screens are suitable for charcoal powder with a wide particle size distribution, high impurity content, and a lighter specific gravity. Its screening mesh range is 20–325 mesh, and its typical screening output is 200 kg/h–3 t/h. The equipment can be configured with one to five screen layers, achieving multi-stage screening. In the activated carbon production process, circular vibrating screens are used to remove sawdust, stones, and metal impurities from the raw charcoal, ensuring the purity of the material entering the activation furnace.

Ultrasonic vibrating screens are particularly suitable for ultrafine charcoal powder or powders that are prone to agglomeration and have strong electrostatic properties. By superimposing high-frequency vibration signals on the ultrasonic vibration system, they effectively prevent screen clogging and sticking. The screening range is 100–500 mesh, with high screening accuracy and a throughput of approximately 100 kg/h–800 kg/h. Typically configured with one to three screen layers, they are used for grading and removing impurities from high-value-added fine charcoal powder.

Linear vibrating screens are suitable for processing charcoal powder with low moisture content and large particle size. Available with 1-5 screen layers, the screen mesh typically ranges from 10-200 mesh, and the screening capacity can reach 500kg/h-5t/h. For example, a customizable double-deck linear vibrating screen can precisely separate charcoal powder into three distinct product sizes: coarse particles, medium particles, and ultra-fine powder, all in one operation, delivering high performance.

Charcoal Powder Grading Vibrating Screen Main Components

The components and functions of a charcoal powder grading vibrating screen are as follows: The screen box is the core screening chamber, holding the charcoal powder to be graded. The vibrating motor provides the power source for the equipment, generating directional vibrations that cause the charcoal powder to move regularly across the screen surface. The screen is a key component for grading, with different mesh sizes intercepting charcoal powder of corresponding particle sizes, achieving multi-level separation. The sealing cover prevents charcoal powder from spilling during screening, and the shock absorber absorbs the impact force generated by vibration, reducing noise during operation and protecting the frame structure.

What are the applications of a charcoal powder grading vibrating screen?

In the consumer sector, charcoal powder grading vibrating screens are used to produce barbecue charcoal, heating charcoal, and mosquito coil charcoal of varying coarseness and fineness. In the industrial sector, they are used to process carburizing agents for metallurgy, steel insulation, and charcoal powder used in gunpowder and fireworks. In the high-tech sector, charcoal powder of the specific particle size required for battery electrode materials, pencil leads, polishing agents, and more is used for the initial grading of activated carbon.

Charcoal Powder Grading Vibrating Screen Suppliers

Suppliers of charcoal powder grading vibrating screens can recommend suitable models or customize them based on the material being screened. For example, Dahan Vibration Machinery, established 15 years ago, has extensive experience and customization capabilities, offering personalized screening solutions based on material characteristics. The equipment utilizes high-quality vibrating motors and wear-resistant screens, and provides installation, commissioning, training, and accessory support.

Charcoal powder grading vibrating screens are essential and critical equipment in the charcoal powder production process. Charcoal powder is light, loose, easily airborne, and has an uneven particle size distribution. This equipment uses high-frequency vibration screening to effectively prevent dust from scattering, improving the uniformity and purity of the finished product. This enables precise grading, purification, and stabilization of charcoal powder, significantly enhancing product added value and market competitiveness. The equipment can flexibly adjust the screen layer and mesh specifications to meet varying particle size requirements, achieving precise grading from coarse to fine powder. Different types of vibrating screens can be flexibly selected based on charcoal powder characteristics, particle size requirements, and production volume requirements to achieve optimal screening results.
