summary:

The coal drop strength tester is used to measure the crushing strength of industrial coal, and the product is based on the coal industry standardMT/T 925-2004Method for Measuring the Falling Strength of Industrial Briquette and Referring to the National StandardGB/T15459-1995Design and manufacture of the method for determining the crushing strength of coal.

Instrument measurement principle:

According toMT/T 915The regulations require the use of coal samples, and then according toMT/T 916According to the regulations, it is necessary to use the long strip method to divide it6kgCoal sample, with a basic intact appearance and no cracks, not less than60One, make the sample reach a state of air drying, remove incomplete and cracked coal from it, and divide the remaining coal samples according to regulations10Randomly select a coal block from each small block with equal area10As a sample, take another sample using the same method10As another sample.

Weigh the mass of a sample accurately until it reaches the mark1gRemove the sample from the test stand2MOne by one, freely fall from a high place onto the steel plate, and after falling, sieve out particles larger than13Millimeter sized coal blocks are dropped and sieved using the same method3Next time. After each coal type falls, the falling position should be cleaned before conducting the next coal type falling test. Weighing the item3After secondary screening, the particle size is larger than13The mass of millimeter sized coal blocks, accurately weighed to1gCalculate according to the standard calculation method to obtain the drop strength value of the coal.

The instrument consists of steel plates, frames, marking rods, positioning wheels, and dropping devices. Place the prepared coal blocks in the material tray, press the button, and the instrument will automatically rise. When it reaches the specified height, the lifting will stop and the material tray will automatically fall down. The coal blocks will fall into the steel plate frame and operate according to the standard required number of drops.

The instrument is accurate in measurement and easy to operate, making it an essential tool for determining the falling strength of coal.
