X-ray sorting of minerals-XRT Sorting in Coal and Mineral Ores

XRT Intelligent Dry Type Coal and Mineral Ore Separator

What is XRT Separator?

Based on the sensor technology and X-ray transmission technology, the XRT Intelligent Mineral Ore Dry Separator provides a brand-new solution for mineral ores sorting to remove the waste and coal gangue. The sorting system adopts our unique AI Computer algorithm to recognizes the internal physical characteristics of the extracted materials and sorting the coal and gangue away by the high-pressure blower, based on customer's requirements.

Working Principle

The equipment uses X-ray to scan the raw ore, collects data from the detector, and distinguishes the ore and waste rock through intelligent algorithm, and blow the waste rock away with the High-pressure blowers.


Main Structure

l  Feeding system:The belt conveyor is used to make the ore stably enter the scanning area to ensure the accuracy of detection and separation.

l  Detecting system:An X-ray source is installed on the top of the system and, after the ray irradiates the ore, the detector receives the X-ray signal and converts & collects it. Then uploads it to the data processing system.

l  Data Processing system:Using the AI algorithm to analyze the ore image and data, achieving the recognition of the ore and waste. At the same time, it is decided whether the target ore (waste) needs to be removed by blowing.

l  Executing system:The target ore is ejected away from the original route by the power of the high-pressure pneumatic blowers to achieve the purpose of separation.



Does It's Used in Coal Only? -NO

The sorting machine has been successfully used in tungsten, tin, antimony, lead-zinc, copper, gold, silver, molybdenum and other metal mines, as well as non-metal mines such as coal, fluorite, phosphorus, Ferro sulfide, etc. Our sorting machine is currently the only X-ray intelligent sorting machine with mature application cases in non-ferrous metal ore, ferrous metal ore, non-metallic ore, coal mine and other fields.

XRT Separator: Improve your Productivity

1.  Wide range of particle size, including + 8-40mm, + 12-60mm, + 20-100mm, + 50-300mm.

2.  The space of air blowers can be selected flexibly (7mm, 10 mm, 12.5mm) according to the requirements of ore processing capacity and the size of ore particles.

3.   Among the range of + 12-60mm grain size, the average output can reach about 60-100tph; for + 20-100mm, the output is more than 120t / h. When processing large grain size coal mines, the output is as high as 400t / h.

4.   The data processing system adopts high integration AI algorithm to achieve millisecond operation rate and high processing capacity of ore dressing recognition rate. Which can increase ore recognition ability and accuracy, improve ore separation accuracy and make the separator is suitable for many kinds of ores.

5.  Safe operation and maintaining cost.

6. It takes replace of hand sorting in some certains with higher efficiency.
