Coal and its processed products, such as coke and blue coke, are the main power fuel in thermal power, iron and steel, metallurgy, chemical industry, glass, ceramics, industrial boilers and other industries, and are related to many fields of national economic production and life. The inflammable and explosive characteristics of these materials put forward stricter requirements for their grinding and pulverizing process and equipment. How to prepare pulverized coal powder safely and effectively has become the focus of the industry. Guilin Hongcheng has devoted many years of research in the field of coal pulverization. The complete set of processing and production lines are mature, safe and reliable, and have been successfully applied in many places.

Technical Indicators

Coal Grinding Process Flow

Production Process Flow

Crushing: large pieces of raw coal need to be crushed first, and the particle size of grinding should be within 2cm.

Production Process Flow

Drying+Grinding: The material is crushed under the force of the grinding roller. The grinding gas flows through the hot blast stove to raise the temperature, which can dry the material.

Production Process Flow

Classification: The crushed material is blown into the classifier by the airflow. Pass if qualified, continue to grind if unqualified.

Production Process Flow

Collection: The selected qualified materials enter the pulse dust collector or cyclone dust collector, and are sent to the next process through the discharge valve.
