Vertical Roller Mill is our newly-launched product which is applied as a solution to the technical issues such as low output and high energy consumption in the ordinary industry. This new type product is developed based on years of production and development on the pulverizer through analyzing and researching the strengths and weakness of both foreign and domestic products of its kind. Its performance has entered into the leading level among the international products of its kind. Vertical Roller Mill is a new type advanced pulverizing equipment featuring good performance and drying function. Integrated with drying, pulverizing and powder-selection, Vertical Roller Mill is widely applied in cement, chemical, coal and electric power industries. It has become the mainstream equipment in the pulverizing industry.
The equipment integrates the functions of crushing, drying, grinding, powder separating and transportation, featuring simple system and compact layout, with the floor space of about 50% of that of the ball-milling system. And it can be arranged outdoors so as to greatly reduce the investment costs.
Less wear: The roller does not contact the grinding plate directly and the roller and grinding plate are made of high-quality materials. Therefore, they enjoy longer service life and less wear. High efficiency: The grinding rollers can directly grind materials on the grinding plate, featuring lower energy consumption (30% ~ 40% lower than that of ball-milling systems).
The equipment is provided with an expert automatic control system, realizing free switching between remote and local control to achieve easy operation and save labor costs.
The equipment can operate stably with little vibration, so its noise is fairly low. The system is wholly sealed and works under negative pressure, free of dust spillover and environmentally friendly, with the emission meeting the national standard.
The main motor drives the grinding plate via the reducer. Hot air flows into the vertical mill through the air inlet, while raw materials fall onto the center of the grinding plate from the feed port. Driven by centrifugal force, the materials spread outward evenly.
As materials pass through the grinding zone, they are crushed and milled by grinding rollers. Coarse lumps are directly broken down, and fine particles form a material bed for further inter-particle grinding.
Ground materials move toward the mill edge and are carried upward by strong airflow. Oversized particles drop back to the grinding plate for regrinding. When airflow passes through the top separator, coarse grains are intercepted and sent back for repeated milling. Qualified fine powder is transported out and collected by the dust collector as final products.
