Processing Calcium Carbonate Powder: Essential Equipment

Calcium carbonate is a common industrial raw material widely used in various fields such as construction, plastics, and papermaking. Processing calcium carbonate is crucial, and selecting the right grinding equipment is key to ensuring processing efficiency and product quality. This article will provide a detailed introduction to the equipment required for processing calcium carbonate powder, the grinding process, and how to choose suitable equipment.

What is the Calcium Carbonate Grinding Process?

The processing of calcium carbonate typically includes the following steps:

Crushing: Large blocks of calcium carbonate raw material are crushed using a crusher to a particle size suitable for the feed of the grinding machine.
Grinding: The crushed material is conveyed by a bucket elevator to a storage hopper and then uniformly and quantitatively fed into the grinding chamber of the mill by a vibrating feeder for grinding.
Classification: The ground material is classified through a classification system. Powder that does not meet the required specifications is returned to the mill for regrinding.
Powder Collection: Powder that meets the fineness requirements passes through a powder separator and enters a dust collector with the airflow for separation and collection. 

What Equipment is Needed to Process Calcium Carbonate Powder?

The processing equipment for calcium carbonate mainly includes the following categories:

Crusher: Used to crush large blocks of calcium carbonate raw material to a particle size suitable for the grinding machine.
Bucket Elevator: Used to lift raw materials to the storage hopper.
Conveyor: Responsible for conveying raw materials and finished powder.
Vibrating Feeder: Uniformly and quantitatively feeds raw materials into the grinding chamber of the mill.
Grinding Mill: The core equipment in calcium carbonate processing, commonly including Raymond mills, MTW European-style mills, vertical roller mills, etc.
Dust Collection Equipment: Used for dust removal during powder collection.

How to Choose a Calcium Carbonate Grinding Mill?

Selecting the right calcium carbonate grinding mill is crucial for ensuring processing efficiency and product quality. Here are some selection suggestions:

1. Choose the Model Based on Production Needs:

MTW European-style Mill: Meets production demands of fine powder with a particle size range of 200-33μm (80-425 Mesh), with a production capacity of 3-50 tons per hour.
Raymond Mill: Meets production demands fine powder with a particle size range of 80-325 Mesh, with a production capacity of 4-300 tons per hour.
Vertical Roller Mill: Adjustable output fineness ranging from 325 Mesh to 2500 Mesh, with a production capacity of 500-25,000 kilograms per hour.

2. Consider Equipment Performance:

Wear Resistance: Choose grinding rollers and rings made of wear-resistant alloy materials to increase equipment lifespan.
Energy Consumption: Low-energy consumption equipment can reduce production costs.
Fineness Adjustment: Select equipment with adjustable output fineness based on needs.

3. Refer to Customer Feedback:

Choose manufacturers with positive customer feedback and after-sales service to ensure technical support and maintenance services during equipment use.
