Ultra-Fine grinding processing method and flow of heavy calcium powder

Heavy calcium powder, as an important material in various industries, has been widely used due to its excellent physical and chemical properties. The ultra-fine grinding of heavy calcium powder is essential to improve its application range and performance.

1. Introduction

Heavy calcium powder, also known as calcium carbonate, is a commonly used filling material in the industries of plastics, rubber, paper, paint, and pharmaceuticals. The particle size of heavy calcium powder directly affects its performance and application fields. Ultra-fine grinding of heavy calcium powder can effectively improve its activity, whiteness, and dispersibility, thereby enhancing the product quality of downstream industries.

2. Grinding Methods of Heavy Calcium Powder

Ball Mill Grinding

Ball mill grinding is one of the most traditional and widely used methods for ultra-fine grinding of heavy calcium powder. The working principle is to rotate the cylinder with the grinding body (steel ball) to generate collision, friction, and compression forces on the material, achieving the purpose of grinding.

Roller Mill Grinding

Roller mill grinding uses a pair of rollers to press and grind the material. This method features high production efficiency, low energy consumption, and easy maintenance. The particle size of the heavy calcium powder can be adjusted by changing the gap between the rollers.

3. Ultra-Fine Grinding Process of Heavy Calcium Powder

The ultra-fine grinding process of heavy calcium powder mainly includes the following steps:

Crushing and Grinding

The raw material is first crushed to a suitable size by a jaw crusher or impact crusher, and then enters the grinding equipment (such as ball mill, roller mill, or jet mill) for further grinding.

Classification

After grinding, the material enters a classifier for classification. The classifier separates the ground material into different particle sizes, and the coarse particles return to the grinding equipment for re-grinding.

Collection

The fine powder meeting the requirements is collected by a dust collector and packaged as the final product.

The ultra-fine grinding of heavy calcium powder plays a crucial role in improving its application performance. Choosing an appropriate grinding method and optimizing the grinding process are essential for achieving high-quality heavy calcium powder. With the continuous development of grinding technology, the ultra-fine grinding of heavy calcium powder will have a broader application prospect in various industries.
