Grinding Agent Gear Metering Pump for Cement

Main features of Grinding agent gear metering pump

Cement grinding aids are now more and more used in cement plants because of their energy saving, environmental protection, greening, and the ability to reduce the production cost of cement plants. In order to accurately add cement grinding aids to the mill, cement grinding aids We have designed the Maximum performance and maximized the cost of grinding aids. We have designed a medium-controlled grinding aid intelligent joining system. 

    

The system is to add the mill system and the grinding aid to the system to realize the central control connection, so that the cement plant's original central control system can realize the control and feedback of the grinding aid addition, and the grinding aid is added to the system, the metering system and the flow feedback system. Docking. The grinding aid is added to the system and the grinding system is always under monitoring. As the grinding machine changes, the grinding aid is added to the system, which not only makes the grinding aid in the cement production process more. Accurate, allowing grinding aid manufacturers and cement plants to control costs, but also to control the quality of cement.
 

Operation principle

The purpose of the system design is to ensure the stable addition of the grinding aid, so that the whole system can be intelligent and automated. Therefore, it is necessary to realize the following functions, adding smooth and non-pulsating, detecting and feedbacking the flow rate, adding the grinding machine to be uniform, preferably atomizing and spraying, realizing the connection of various key components and the cement plant central control system, flow and grinding When the machine is in motion, etc. It can realize the time monitoring of the liquid tank liquid in the central control system, the time monitoring of the filter working condition, the control and processing of the working signal of the metering pump, the processing of the signal of the flow sensor and the correction of the flow rate. When the system has abnormal conditions, the system will automatically alarm. This not only avoids the unevenness of the grinding aid, but also protects the system well, and the amount of grinding aid is added.

 

Main products

● Two metering pumps (one for one), adding grinding aids, require smooth flow and no pulsation. Therefore, it is necessary to select Youke Precision Flow Gear Metering Pump, which is accurate in measurement and high in repeatability. Because the amount of grinding aid is from two ten thousandths or three ten thousandths or three ten thousandths to one thousandths or two thousandths. And because the general cement mill table ranges from 50~60 tons to 240 tons, the metering pump needs to reach the range from 0-500L/H, and the accuracy of the pump should be guaranteed in this interval.
● One precision flow meter requires an accuracy of 0.5%. The range meets 4-5L per hour from a small flow rate. To 500-600L per hour. Youke Precision Flowmeter is able to meet the accuracy from small flow to full scale.
● One system control cabinet, including control switches for each pump, frequency converter pump, flow calculator, signal isolator, etc.

 

System functions

● Ability to manually control the operation on site, or control the operation in the middle
● Completely docked with the central control system
● The central control can start and stop the pump. And adjust the flow
● Youke Precision Flowmeter can feedback and record the instantaneous flow of the metering pump, accumulate the flow, and compare it with the given flow for closed-loop flow calculation
● If the metering pump fails, there will be an alarm
● If the metering pump line is blocked or there is no material in the metering pump, the system will also alarm.
● Grinding aid can be added to an accuracy of 0.5%
