Process analysis
The raw coal in the raw coal bin enters the scraper conveyor through a quantitative belt feeder, and is sent to the dryer for drying through the scraper conveyor. The dried raw coal is transported to the closed storage bin through a closed scraper conveyor, and then transported to the raw material storage bin of the pulverizing system through transport vehicles. It is fed into the MTW215 European version pulverizer through a weighing coal feeder, and the ground powder is graded by the powder selection machine, Enter the powder collector along the pipeline (the remaining gas is collected by a pulse dust collector), and the collected finished coal powder enters the coal powder elevator through a screw conveyor system. It is lifted to the finished coal powder silo for storage and transported by tank trucks as needed. The entire system includes a nitrogen generation system and a CO2 system, providing explosion-proof and fire extinguishing protection. Key components are installed with explosion-proof valves to prevent equipment damage.
Project advantages
Project general contracting services
In order to save construction time to a great extent and reduce customer investment, this coal powder preparation project adopts project general contracting services. The project general contracting service is a "turnkey" service project designed by Shibang Group specifically for the convenience of customer production requirements. This service runs through various stages such as on-site terrain and environmental survey and investigation, production line process design, raw material testing and testing, finished product requirement analysis, customer investment cost budget, equipment installation and debugging, etc; It can avoid delaying the production time of the project due to special factors such as building material preparation and insufficient manpower caused by the client. The project general contracting service greatly facilitates the production of customers, meets their urgent needs for production time, and has won high praise from customers in Shandong.
Easy to operate
In order to improve the simple and easy operation performance of the coal powder production line, the production line adopts a unique two-step drying and grinding method for operation. The two-step coal powder preparation system refers to a solution for drying and powder separation. The grinding chamber temperature is relatively low, and it is a unique coal powder preparation process of MTW European version mill. The process system is relatively simple and easy to control, while greatly improving the safety performance of the production line.
System composition: 1. Raw coal bin 2. Drying machine 3. Weighing coal feeder 4. MTW European version coal mill 5. Pulse dust collector 6. Dust collector 7. Fan 8. Finished coal bin 9. Pulverized coal bin 10. Monitoring system 11. Explosion proof system 12. Central control system
Low investment
The MTW European version mill adopts multiple world advanced technologies such as bevel gear overall transmission, internal thin oil lubrication system, and online oil temperature measurement. It has multiple independent technical property rights, and the entire system has many advantages such as small footprint, low comprehensive investment, low operating cost, high efficiency, and environmental protection.
High safety and environmental performance
In order to ensure the fire and explosion safety performance during the coal powder preparation process, the production line is equipped with a nitrogen system and a CO2 fire extinguishing system, greatly ensuring the safety and stability of equipment operation.
At the same time, effective measures have been taken to strictly control the dust concentration of exhaust emissions within the national regulations. The production line adopts advanced technology produced pulse dust collectors, which greatly reduces the impact of the production line on the surrounding environment
Working principle of European humic acid 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 environmentally friendly production while adjusting the airflow balance of the system.
