Working Principle:

This mechanical inert gas protected pulverizer is specifically designed and developed for flammable, explosive, and easily oxidized materials. By modifying the airflow and the equipment's inlet and outlet, the sealing performance is improved. The entire system uses inert gas as the working medium, with the exhaust fan outlet connected to the pulverizer's inlet, forming a closed-loop inert gas circulation system. The complete set of equipment consists of an inert gas source, an oxygen content analyzer, an inlet pipeline system, a closed-loop feeding system, a vertical turbine classifier, an exhaust fan, a sealed displacement discharge valve, an anti-static pulse reverse air dust collector, and an inert gas replenishment device.

Equipment Characteristics:

• Select an inert protective gas suitable for the characteristics of the material to be pulverized.
• Control the purity of the inert gas according to the characteristics of the product and process requirements.
• The entire equipment features closed-loop pulverization, with inert gas recycling, resulting in low loss, reduced costs, and no environmental pollution.
• Can be used in series with a classifier to produce products of multiple particle sizes simultaneously.
• The entire system is program-controlled, enabling automatic replenishment and discharge of inert gas to maintain system pressure balance and simplifying operation.
• The dust removal equipment utilizes low-pressure, short-pulse jet cleaning technology, ensuring stable operation over extended periods.
• Particle size can be adjusted arbitrarily without stopping the machine, resulting in uniform product particle size.
• The machine has a compact and reasonable structure, small size, low energy consumption, and high efficiency.
• The integrated pulverizing and classifying machine can promptly convey materials that meet the fineness requirements, avoiding over-pulverization and resulting in a narrow particle size distribution.

Application Scope:

It has a wide range of applications and is suitable for crushing flammable, explosive, and easily oxidized materials, such as sulfur and reduced iron powder.
