Because gypsum is so soft, most drills can drill through it at a rate of roughly 23 ft per minute. Sometimes the drill holes become wet, which can cause problems with the ammonium nitrate. In these cases the ammonium nitrate is bagged in plastic bags before being lowered into the blast hole. Mines use approximately 1 kg of explosives for each ton of gypsum they blast. Gypsum Uses. The most
Aug 01, 2014· The key is to predict the amount of nitrogen per ton of material that will volatilize and then apply enough gypsum to capture that ammonia into a stable ammonium sulfate form. Of course, the end product will contain calcium, ammonium sulfate and other nutrients and carbon. Dr. Davidson posts articles on soil management and subjects to gypsum.
Bauermeister Mills are widely used for grinding Urea, however Ammonium nitrate, sulphate as well as other chemical fertilizers can be granulated as well. A typical required fertilizer particle size is in granules from 2 to 4 mm. Bauermeister Roller Mills provide the ideal technology for achieving this granulation while generating a minimized amount of dust.
Ammonium nitrate, without a reasonable amount of fuel had essentially zero risk of detonating. Obviously, this does not apply to grinding premixed pyrotechnic materials that include ammonium nitrate and fuels. Thus still will not result in a detonation, but could very well ignite and burst the grinder or

Canada Mexico and Spain are other significant producers of raw gypsum In all more than 90 countries produce gypsum In most open pit gypsum operations benches are drilled and blasted using ammonium nitrate as the explosive Because gypsum is so soft most drillsWe are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other
The total grinding time for 200 grams of ammonium nitrate charged was somewhat more than one-half hour. The 9600 rpm. material formed lumps in a short time and in about 2 days was caked solid when...
Ammonium nitrate is an oxidiser it doesn't burn or explode, it helps other stuff burn and explode. Mix it with a fuel (charcoal, sugar etc) and grind it vigorously and then you're in trouble. Bit of advise ammonium nitrate is hygroscopic it absorbs water easily from the air around it so keep it stored in an air-tight container.

The invention provides a method for producing nitrophosphate fertilizer and co-producing high-purity gypsum through decomposing phosphorite with nitric acid, belonging to the technical field of compound fertilizer production. The method comprises the following steps: decomposing the phosphorite with the nitric acid, and filtering acid-insoluble substances; then adding ammonium sulfate or
The table shows that the sample of ammonium nitrate according to GOST 2-85 without additives bridge, harden, clog and crushing it took the pressure of 16 kg/cm 2 (experiment 1).. Samples of the same nitrate content anti-caking additives from 0.01% to 0.075% (experiments 2-5, 15 and 16) bridge, harden, clog much less, and with increasing content of additives pressure required for crushing
