How Does The Graphite Grinding Plant Process?

The graphite grinding plant is suitable for processing nonflammable and explosive mineral materials with Mohs hardness below level 8 and humidity less than 6%. Graphite is a nonmetallic material with high thermal conductivity, heat resistance, chemical stability, electrical conductivity, and lubricity. It has wide applications in batteries, electrodes, lubricants, composite materials, and high-temperature materials.

Applications of Graphite

The application range of graphite grinding equipment is extensive. It has wide applications for graphite products such as electrodes, heat exchangers, refractory materials, etc. In addition, graphite grinding equipment is widely used in fields such as chemical engineering, metallurgy, building materials, pharmaceuticals, etc.

The applications of graphite powder

Mold-release lubricant in catalysts in the fertilizer industry.
Graphite powder has the characteristics of high-temperature resistance and high lubricity. It is a high-temperature-resistant lubricant and corrosion-resistant lubricant base material.
Powder metallurgy release agent and metal-alloy raw material, a lubricant in cable production.
Carbon film resistors, dry molds for conductivity, and to prepare conductive coatings.
Filler or performance modifier for rubber, plastics, and various composite materials to improve their wear resistance, compression resistance, or conductivity.

Graphite grinding plant processing equipment

The equipment for graphite grinding plants mainly includes crushers, ball mills, mixers, dryers, sintering furnaces, graphitization furnaces, processing equipment, etc. These machines will be configured and arranged according to a process flow to ensure the quality and output of graphite products.

Graphite crushers

There are many types of graphite crushers. Because graphite is a dark gray and opaque solid with a Mohs hardness of 1-2 and a specific gravity of 1.9-2.3. It usually adopts jaw crushers and impact crushers. Jaw crusher has strong crushing force and stable performance.

The graphite crushers can effectively crush large graphite raw materials into smaller particles. The graphite particles that have undergone initial crushing will enter the impact crusher for further crushing and refinement.
The impact crusher has a high-speed rotating hammer and impact plate to crush graphite particles into finer powders. The graphite powder from the impact crusher will undergo a series of screening and grading to obtain graphite powder that meets the requirements.

1. Jaw crusher

Jaw crusher is widely used in metallurgy and chemical engineering. It has the advantages of good performance and high productivity, so they occupy a large proportion of small and medium-sized series crushers and have a trend of continuous development toward large-scale drying equipment.
After understanding the working principle and process, the crushing plates of the moving and fixed jaws should have their tooth peaks aligned with their tooth valleys. In this way, in addition to the squeezing effect, there is also a bending effect on the material during crushing, making it relatively easy to break.
The Jaw crusher’s design also fully considers energy-saving and environmental factors. The optimized crushing chamber and reasonable working parameters can effectively reduce energy consumption and improve energy utilization efficiency. At the same time, the dust and noise generated during the crushing process are under control, reducing environmental pollution and the impact on the health of operators, which is in line with the concept of modern industrial green development.

2. Impact crusher

The impact crusher can process materials with a side length of 100-500 millimeters or less, with a maximum pressure resistance of 350 MPA. It has the advantages of a large crushing ratio and with cubic material particles. This machine is widely used in building materials, ore crushing, railways, highways, energy, transportation, cement, mining, and other industries. The particle size of its discharge is adjustable, and the crushing specifications are various.
The impact crusher uses the principle of impact crushing to crush materials. It usually cooperates with the jaw crusher for crushing in stone production lines.

Graphite grinding equipment

Graphite grinding equipment is a mechanical machine for graphite crushing and processing.

It is mainly used to grind graphite raw materials into small powders for subsequent processing and application. Graphite grinding equipment usually consists of a grinder, grinding wheel, conveying system, classifier, dust removal equipment, etc.
The grinder is the core component of graphite grinding equipment, which mainly uses high-speed rotating grinding wheels to grind and crush graphite raw materials.
When selecting graphite grinding equipment, it is necessary to choose the appropriate equipment based on the properties and processing requirements of the graphite raw materials, while also considering factors such as equipment quality, performance, and price.

Graphite grinding plant process flow

The production process of graphite powder is as follows:

Raw material preparation

Select high-quality natural graphite ore as the raw material, and through processes such as ore crushing, grinding, and screening, obtain suitable raw materials for producing graphite powder. Primary crushing usually uses equipment such as jaw crushers or impact crushers.

Graphite powder grinding

Put the raw graphite ore into a graphite grinding and crushing machine, and use mechanical force to grind the ore to the desired particle size. The primary crushed graphite ore enters the grinding process, usually using equipment such as a grinding mill. The grinding process of graphite requires the use of special grinding tools and abrasives to ensure the quality and purity of graphite

Separating

The ground graphite powder enters the screening equipment to separate graphite powder of different particle sizes to meet various application requirements. Screen and grade the graphite powder to remove impurities and control the particle size and distribution of the powder.

Graphite powder drying

Place the graphite powder into drying equipment. Evaporate or remove the moisture in the graphite powder through hot air to achieve the desired moisture content. Collect and process dust and exhaust gases generated during grinding and screening processes to protect the environment and the health and safety of workers.

Surface treatment of graphite powder

By mixing with surfactants and other substances, graphite powder surface treatment improves its dispersibility, wettability, and flowability.

Graphite powder grinding plant can be designed into different process flows and equipment combinations according to the process requirements to meet various requirements and application scenarios of customers. In general, when choosing a graphite mill, it will consider multiple factors comprehensively to ensure selecting a suitable graphite grinding mill with high efficiency and quality.
