Vertical Mill for Gypsum - High Efficiency Grinding for
Construction Materials
Gypsum vertical grinder is an industrial equipment specifically
designed for gypsum grinding, which has the characteristics of high
efficiency, energy saving, and environmental protection. The following are the main properties and detailed descriptions of
gypsum vertical mills:
1. Core attributes
Equipment type: Vertical Mill
Applicable materials: gypsum (natural gypsum, desulfurization
gypsum, phosphogypsum, etc.)
Working principle: By the relative motion of the grinding roller
and grinding disc, gypsum is crushed, crushed, and ground.
Finished product fineness: adjustable, usually ranging from 80-325
mesh, to meet the needs of different industries.
2. Performance characteristics
Efficient grinding:
Adopting a vertical structure, it has high grinding efficiency and
low energy consumption.
One grinding can achieve the desired fineness without the need for
secondary processing.
Energy conservation and environmental protection:
Energy consumption is 30% -50% lower than traditional ball mills.
Adopting a closed system with low dust emissions, it meets
environmental standards.
Stable operation:
The equipment has a compact structure, low vibration, low noise,
and smooth operation.
High degree of automation, capable of remote control and
monitoring.
Strong durability:
The key components are made of wear-resistant materials (such as
high chromium alloys), which have a long service life.
Easy maintenance and low repair costs.
3. Technical parameters
Production capacity: usually 5-100 tons/hour, can be customized
according to demand.
Motor power: Depending on the model, the power range is 75-1500 kW.
Feed particle size: ≤ 50 mm.
Finished product fineness: 80-325 mesh (adjustable).
Moisture requirement: The moisture content of the feed should be ≤
15%.
4. Application Fields
Building materials industry: used for producing gypsum powder,
gypsum board, gypsum mortar, etc.
Chemical industry: used for grinding desulfurization gypsum and
phosphogypsum.
Environmental Protection Industry: Used for the resource
utilization of industrial by-product gypsum.
Other fields: such as ceramics, coatings, pharmaceuticals, and
other industries.
5. Advantage comparison (compared with traditional ball mills)
Attribute gypsum vertical mill, traditional ball mill
Low energy consumption (energy-saving 30% -50%) and high
Small and large footprint
High grinding efficiency but low
Environmental performance: less dust, low noise, and high levels of
dust and noise
Low and high maintenance costs
6. Optional Configuration
Hot air system: used for drying wet gypsum and improving grinding
efficiency.
Dust removal system: equipped with bag filter or electrostatic
precipitator to reduce dust emissions.
Automated control system: enables remote monitoring and automated
operations.
Upgrade the material of wear-resistant parts, such as high chromium
alloy grinding rollers and grinding discs, to extend their service
life.
7. Applicable scenarios
Large scale production: suitable for large-scale production in
industries such as building materials and chemicals.
Resource utilization: used for the treatment of industrial
by-products such as desulfurization gypsum and phosphogypsum.
High fineness requirement: Suitable for industries with high
fineness requirements for gypsum powder.
Operational Principle
The electric motor drives the grinding plate to rotate through a
reducer, and the material falls into the center of the grinding
plate from the feed inlet, while hot air enters the grinding
chamber from the air inlet. Under the action of centrifugal force,
the material moves towards the edge of the grinding disc and is
crushed by the grinding roller when passing through the circular
groove on the grinding disc. The crushed material is carried up by
the high-speed airflow at the edge of the grinding disc, and large
particles directly fall onto the grinding disc for re grinding.
When the material in the airflow passes through the dynamic and
static separator, under the action of the rotating rotor, the
coarse powder falls onto the grinding disc for re grinding, and
qualified fine powder is discharged with the airflow, Collect in
the powder collection device, which is the product. Materials
containing moisture are dried during contact with hot gases to
achieve the required product moisture.
