Description

Technical Field

[0001] This utility model belongs to the technical field of crushing and drying devices, and in particular relates to a crushing and drying device for coal testing. Background Technology

[0002] The purpose of testing coal is to comprehensively understand its quality characteristics, assess its industrial value and applicability. By testing indicators such as coal composition, calorific value, and particle size, it is possible to determine whether coal meets the usage requirements of different industries, such as thermal power generation, steel smelting, and chemical production. At the same time, it also helps to optimize coal mining and processing procedures, improve energy efficiency, ensure production safety, reduce environmental pollution, and meet the quality standards and environmental protection regulations of relevant industries. When testing coal, it is crushed to increase the contact area between the coal and the testing reagents and instruments, making the testing process more thorough and rapid, ensuring that the internal components of the coal are evenly exposed, thereby obtaining more accurate and representative test results.

[0003] However, existing crushing and drying equipment cannot ensure the uniformity of the particle size of the crushed coal during the crushing process, which can lead to insufficient representativeness of coal samples, deviations in test results, and inaccurate reflection of the true quality characteristics of coal, thereby affecting the judgment of the industrial value and applicability of coal.
