A roll crusher is a piece of heavy-duty equipment used in mining and
industrial processes. It features a pair of large wheels or cylinders mounted
on horizontal axis. When rocks, ore, and other materials pass between the two
cylinders, they are crushed or ground into smaller pieces. Roll crushers are
commonly used in primary, secondary, and tertiary crushing stages to break down
different types of rocks and minerals. They are often used in coal mining
operations and in the processing of industrial minerals.

(2) Determine the target size: When measuring temperature, the measured target area should be full of the thermometer field of view. It is recommended that the measured target size exceed 50% of the size of the field of view. If the target size is smaller than the field of view, background radiation energy will interfere with the reading, causing errors. Conversely, if the target is larger than the thermometer's field of view, the thermometer will not be affected by background radiation outside the measurement area.
(3) Accuracy: The use of any instrument must be considered. Infrared thermometers are no exception. The choice must also be considered comprehensively. It is not always better. It is better to meet your own requirements and within the cost budget.
(4) Determination of optical resolution Optical resolution is determined by the ratio of D to S, which is the ratio of the distance D from the pyrometer to the target and the diameter S of the measurement spot. If the pyrometer must be installed far away from the target due to environmental conditions, but also to measure a small target, you should select a high-resolution optical thermometer (5) to determine the response: Response time indicates that the infrared thermometer pair The response speed of the measured temperature change, if the target's moving speed is fast or the target of rapid heating is measured, all require a fast response infrared thermometer. When there is thermal inertia for a stationary or target thermal process, the response time of the thermometer can be relaxed. Therefore, the choice of response time of the infrared thermometer should be compatible with the situation of the target being measured.
(6) Consideration of environmental conditions: The environment where the thermometer is located has a great influence on the measurement result. When the ambient temperature is too high, dust is present, etc., the protective cover and other accessories provided by the manufacturer can be used. These accessories can effectively solve the environmental impact and protect the thermometer, enabling accurate temperature measurement.
Nanjing Aoke Select infrared thermometer can be considered from the following aspects: (1) determine the temperature range: temperature range is the most important one of the thermometer performance indicators. Each type of thermometer has its own specific temperature range. Therefore, the user's measured temperature range must be considered accurate and comprehensive, neither too narrow nor too wide.
