200000 Tons Pulverized Coal Production Station (Shandong China)

I. Project overview

Product name: Pulverized coal preparation station

Production scale: Annual output of 200,000 tons of pulverized coal preparation station

Service scope: From raw material storage and transportation, drying, grinding, powder selection to finished product storage and transportation system, environmental dust collection system, electrical automation control system process design, plant planning, equipment supply, equipment installation and commissioning, after-sales training and other one-stop technical services.

In response to the requirements of the environmental protection department of Shandong Province, the boiler is reformed, and a new set of 120 tons of pulverized coal boiler is built, of which the pulverized coal preparation station needs to be built, there are two large vertical mills that are grinding titanium dioxide, and it is necessary to find manufacturers to transform and then build a 30TPH pulverized coal preparation center.

II. Solution

The outstanding advantages of Zheng Mine machine's vertical pulverized coal preparation station:

1, high grinding efficiency, low power consumption;

2, less metal consumption per unit product;

3, bed grinding, low noise;

4, negative pressure operation, small dust pollution;

5, the process is simple, while completing the material grinding, drying, powder selection functions.

The material falls to the center of the mill through the feeding pipe, and the constant speed rotating mill evenly disperzes and smooths the raw material outward by means of centrifugal force, so that it forms a material bed of certain thickness, and the material is simultaneously rolled by several grinding rollers on the mill plate and is crushed. Under the continuous drive of centrifugal force, the material continues to move to the outer edge of the disk. When the material leaving the disk encounters the hot gas entering the mill through the wind ring and rises accordingly, it enters the separator through the middle shell of the mill. In this process, the material and the hot gas carry out sufficient heat exchange, and the water is quickly evaporated. The separator controls the particle size of the finished product at the exit of the roller mill, the particles larger than the specified size are separated and fall back to the mill, and the materials that meet the fineness requirements enter the dust collector through the separator, and the collected finished products are sent to the finished product bin.

Our company's after-sales personnel stationed at the site for more than a month, the operator of the site for training and technical disclosure, so that later owners can better use the equipment. The pulverized coal preparation station of vertical mill has high technical content and difficult process. Zhengmine machine has rich experience in design and production, worthy of customer trust!
