The gangue preparation of organic fertilizer process: the organic matter content of 20%, PH value carbonaceous mud about 6 or siltstone, jaw crusher crushed preliminary Raymond mill, ultrafine powder grinding, high fine winnowing mill grinding mill processing equipment, and then mixed according to a certain proportion of superphosphate, while adding the amount of additives, stir and add the appropriate amount of water, and adequate response to activation retting a new Practical fertilizer. This fertilizer nitrogen, phosphorus, potassium content is not high, but the rich content of organic matter and trace elements boron, zinc, cobalt, manganese, phosphate, ammonium gangue maintained at the molecular adsorption state nutritional elements more easily the crop absorption, in 2 to 3 years, there is a certain fertilizer efficiency.
The study found gangue and a certain percentage of cheap rock phosphate raw materials for the foundation, can produce bio-fertilizers for farming as the main fertilization. As a the microbial fertilizer carrier gangue, its requirements are: ash ≤ 85%, moisture 2% of mercury ≤ 3 mg kg ≤ 30 mg kg of total arsenic, the full lead ≤ 100 mg kg, cadmium ≤ 3 mg kg the full chrome ≤ 150 mg kg; better the higher the organic matter content of the coal gangue rock phosphate phosphorus content of 25%.impact stone breaker: http://www.hxjqchina.com/n115.html
The technical requirements for the use of the gangue improved soil pH its use of coal gangue contains many trace elements and nutrients, can be used to improve the soil to adjust the pH of the soil and porosity can increase soil fertilizer efficiency. Specific implementation, it is necessary to identify the chemical composition and the nature of the soil, and in which the incorporation of organic fertilizer. Before the development of pollution control standards, should refer to GB8193-89 standards.
