Heavy calcium powder production line equipment, Shibang Stone Raymond grinding machine, limestone production line manufacturer

The limestone desulfurization production line for a 300000 ton large-scale power plant in Taiyuan, built by Shibang Group, is a project completed in this context. Now that the customer's production line has been smoothly put into operation for a period of time, let's take a detailed look at the actual situation of the case!

The project is located in Taiyuan City, Shanxi Province, and the client is an old customer of Shibang Group who has been engaged in the preparation of desulfurization agents for many years. In 2009, the customer purchased mill equipment from Shibang Group, processed limestone, and used it as a desulfurization agent for power plants. This equipment has been in use for 8 years since 2017 and still operates smoothly, with stable instrument data. In 2017, due to the construction of two new large units by the power supply plant, customers needed to expand their production scale. Considering that the previous equipment not only operated well, but also provided thoughtful after-sales service. So when the customer made a second purchase, they did not hesitate to choose Shibang Group again.

The European version grinding machine is a new generation grinding equipment designed by Shibang Group, and is an upgraded product of traditional Raymond grinding machines. Developed through the dedicated research and design of dozens of researchers, it has broad application prospects in various fields such as metallurgy, building materials, chemical engineering, mining, etc. With many advantages such as stable operation, high efficiency, low energy consumption, adjustable and controllable product fineness, simple equipment maintenance, and low noise, it effectively breaks through the shortcomings of traditional Raymond grinding machines and becomes a high-quality equipment that meets the needs of the grinding industry. It is widely used in the desulfurization field of power plants and is deeply loved. Next, let's take a look at the advantages of this mill system:

After initial contact with Shibang Group, it was discovered that this is a highly professional team with only one goal: to create greater value for customers. Afterwards, we had multiple collaborations with Shibang Group and found that they were not relying on boasting, but on real skills and real guys. We can deeply feel from the pre-sales, during sales, and after-sales services that we are very relieved to cooperate with such enterprises. Therefore, when we needed a second purchase to expand production, we resolutely chose Shibang Group again.

Working principle of European version limestone grinding machine:

After the large block of material is crushed to the required particle size by a jaw (hammer) crusher, the material is transported to the storage hopper by a hoist, and then evenly and quantitatively fed into the main grinding chamber for grinding by an electromagnetic vibration feeder. The ground materials are fed into the powder concentrator by the fan airflow for classification. Under the action of the impeller of the powder concentrator, materials that do not meet the fineness requirements fall into the grinding chamber for re grinding. Materials that meet the fineness requirements flow through the pipeline into the cyclone powder collector for separation and collection, and are discharged through the discharge device to form the finished powder. The separated airflow enters the fan through the return air duct at the upper end of the cyclone dust collector. The system belongs to a closed loop system and operates under positive and negative pressure conditions. Due to the material being ground in the grinding chamber containing a certain amount of water, the heat generated during grinding can cause the gas inside the grinding chamber to evaporate and expand, changing the gas flow rate of the system. In addition, the sealing problem at the inlet and the joints of various pipelines, the entry of external air causes the loss of air in the system to balance. Therefore, the excess gas is introduced into the bag filter through the exhaust pipe valve set at the fan outlet, and is purified before being discharged, Realize production while adjusting the airflow balance of the system.

Advantages of Shanghai Shibang Calcium Powder Grinder:

Energy saving design, low operating costs

The MTW European version grinding machine adopts a special air duct design and powder selection machine design, effectively reducing energy loss and power consumption, thereby ensuring lower operating costs for the entire grinding system.

Higher transmission efficiency, higher grinding efficiency
