Product name: Pulverized coal preparation station
Production scale: 200,000 tons of pulverized coal preparation station per year
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, factory planning, equipment supply, equipment installation and commissioning, after-sales training, etc. technical services.
In accordance with the requirements of the Shandong Provincial Environmental Protection Department, the boiler must be renovated and a new set of 120-ton pulverized coal boiler be built. Among them, the pulverized coal preparation station needs to be newly built. There are two large vertical mills grinding titanium dioxide. It is necessary to find a manufacturer to transform and build a 30TPH Pulverized coal preparation center.
2. Solution
The outstanding advantages of Zhengkuang Machinery’s vertical mill pulverized coal preparation station:
1. High grinding efficiency and low power consumption;
2. Less metal consumption per unit product;
3. The material bed grinds powder with low noise;
4. Negative pressure operation, small dust pollution;
5. The process flow is simple, and the functions of material grinding, drying and powder selection are completed at the same time.
The material falls into the center of the grinding plate through the discharge pipe. The constant-speed rotating grinding plate uses the centrifugal force to evenly disperse and smooth the raw materials outward, forming a material bed of a certain thickness. The material is simultaneously affected by multiple grinding rollers on the grinding plate. Crushed and crushed. The material continues to move towards the outer edge of the grinding plate under the continuous force of centrifugal force. When the material leaving the grinding plate encounters the hot gas entering the mill through the air ring and rises, it enters the separator through the middle shell of the mill. During this process There is sufficient heat exchange between the medium material and the hot gas, and the water is quickly evaporated. The powder selector controls the particle size of the finished product at the exit of the roller mill. Particles larger than the specified size are separated and fall back to the grinding plate. Materials that meet the fineness requirements enter the dust collector through the powder selector, and the collected finished products are sent to the finished product warehouse.
Zhengkuang’s after-sales personnel have been stationed at the site for more than a month to provide training and technical explanations to the on-site operators so that future owners can better use the equipment. The pulverized coal preparation station of the vertical mill has high technical content and difficult process. Zhengkuang Machinery has rich design and production experience and is worthy of customers’ trust!
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
