Overview
PM-240 plane grinding machine is designed and manufactured by PUSHEN brand in accordance with the requirements of the national standard and the inspection standards of inks, pigment and other industries. It has the characteristics of sturdiness, stability, low failure rate and simple operation, and is suitable for grinding work of pigment, extender and other materials for dispersion evaluation.
Features
1. The structure is sturdy and stable, with a low failure rate and simple operation.
2. The counting control part uses a single-chip microcomputer for accurate counting, reliable operation, and intelligent control.
3. Reducer and motor adopt coupling soft connection, large torque, accurate counting and self-protection function.
4. Grinding Glass is made of heat-resistant and pressure-resistant frosted Glass through fine grinding, with high flatness, durability, and no effect on light-colored samples.
5. There is a chilling down nozzle above the grinding Glass, which can be added with chilling down liquid to avoid grinding Glass rubbing against each other and heating up.
6. Realize physical heat dissipation of ground materials while grinding to achieve accurate grinding results.
Principle
The plane grinding machine is driven by a motor to drive a pair of grinding Glass discs to swirl/spin at a set speed (80 cpm). The user places the material to be ground between the grinding discs and can apply pressure by loading different weights. During the grinding process, the equipment precisely controls the number of grinding turns through the microcontroller, and the chill down system (chill down nozzle) can add chill down liquid to dissipate heat from the grinding area to avoid the accuracy of the grinding result due to friction heat generation, so as to achieve uniform dispersion of the material.
Applications
Inks, pigments, extender industry
Standards
GB/T 21868-5、ISO 787-16、ISO 8780-5、ASTM D 387、ASTM D 2745
Steps
1. Prepare the sample and place it between the pre-installed ground Glass plates.
2. Select the appropriate load weight and load as needed.
3. Set the required number of grinding turns (counting range 0-9999) through the device control panel.
4. Start the equipment, the plane grinding machine will automatically run according to the set number of turns.
5. During the grinding process, the chilling down liquid can be added through the chilling down nozzle for heat dissipation.
6. After the grinding is completed, the equipment automatically stops and takes out the ground sample for analysis.
Notice
The input voltage of the device is 380V AC 50Hz, please ensure that the power supply meets the requirements.
• Check whether the ground Glass is firmly installed and flat before use.
• According to the characteristics of the sample, select the loaded Nominal Mass reasonably to obtain the best grinding effect.
• If necessary during the grinding process, please add the chilling down liquid through the chilling down nozzle in time to prevent overheating from affecting the results.
Do not operate beyond the specified counting range (0-9999) and load capacity of the device.
• Maintain equipment regularly to ensure its stable and reliable operation.
