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
1. Mold-release lubricant in catalysts in the fertilizer industry.
2. 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.
3. Powder metallurgy release agent and metal-alloy raw material, a
lubricant in cable production.
4. Carbon film resistors, dry molds for conductivity, and to
prepare conductive coatings.
5. 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
1. 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.
2. 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.
3. 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
1. 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.
2. 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.
