Natural mineral fertilizers generally refer to various mineral or rock resources that can be directly used in agricultural and forestry production without complex processing, other than traditional N, P, K and other fertilizers. Can granite crushed stone be used as fertilizer? The answer is yes. China is rich in natural mineral fertilizer resources, with various types, wide distribution and shallow burial. After simple processing and crushing, it can be used as fertilizer, soil conditioner and fertilizer additive, etc., and has great potential for development and utilization. HCMilling(Guilin Hongcheng), as a manufacturer of granite grinding mill, will introduce the production and application of fertilizer granite powder for you below.

 

New type granite Raymond mill

Natural mineral fertilizers can provide various nutrient elements required for plant growth and development, and its special physical properties can also improve soil, retain water and fertilizer, and improve plants' ability to resist bacteria. In addition, adding a certain amount of natural mineral fertilizer to the traditional fertilizer can make the traditional fertilizer not agglomerate and increase the utilization rate of fertilizer. The functions of natural mineral fertilizers in agriculture and forestry are summarized in the following aspects.

 

As fertilizer

Natural mineral fertilizers are often rich in macroelements and trace elements necessary for plant growth and development, and can be directly applied as fertilizers after a little processing.

 

As soil conditioner, conditioner

The soil quality of China's agricultural arable land is degraded, and the fertility decline is becoming more and more serious. It is mainly manifested in soil compaction, soil erosion, soil salinization, soil acidification and soil organic matter loss, which seriously restrict the sustainable and steady development of my country's agriculture. Therefore, the development and utilization of natural mineral fertilizers as soil improvement and conditioner have extremely important realism. At present, the minerals or rocks of soil improvement conditioners are used to improve soil, and the effect is remarkable.

 

As fertilizer additive

Adding a certain amount of natural mineral fertilizers to traditional N, P, K and other element fertilizers can improve the performance of fertilizers, prevent the agglomeration (clumps) of fertilizers, improve fertilizer utilization, reduce fertilizer volatilization and prolong fertilizer efficiency. effect. Adding a certain amount of natural mineral fertilizer to traditional farmyard manure can significantly improve the fertilizer efficiency of farmyard manure. In the production of compound fertilizer, adding a certain amount of natural mineral fertilizer can significantly improve the quality of its products, improve the hardness of granulation, prevent agglomeration, reduce dust and debris, and its fertilizer efficiency is also greatly improved. Using natural mineral fertilizers as traditional fertilizer additives not only improves the quality of traditional fertilizers, but also significantly improves crop yield and agricultural product quality.

 

Mineral weathering is a common and very important geochemical process that occurs on the Earth's surface. A large number of studies have shown that lichens have a significant promoting effect on the weathering of rock minerals. The biological weathering of granite by lichen is mainly completed through physical weathering and chemical weathering. Among them, chemical weathering is obviously dominant, and chemical weathering is mainly caused by lichen acids secreted by lichens. Weathering disintegrates. Under natural conditions, lichenic acid can form complexes with metals, thereby significantly promoting the weathering process of rock minerals. During the weathering process, a large number of secondary metabolites produced by symbiotic bacteria of lichens were confirmed to be complex cations, including oxalate, derived from mineral substrates and lichenic acid complexes containing metal cations. Appropriate conditions or parameters to promote the dissolution of mineral elements in granite are of great significance for the preparation of natural mineral fertilizers from granite.

 

The production process of fertilizer granite rock powder: (1) pulverize the granite to 100 mesh by a granite pulverizer; (2) mix the pulverized granite with an oxalic acid solution, and then perform shaking treatment; filter, collect the filtrate, and then get it. The granite grinding mill produced by HCMilling(Guilin Hongcheng) is the production equipment of fertilizer granite rock powder. There are mainly three types of granite Raymond mill, granite vertical roller mill and granite ultra-fine mill. It can produce 80-2500 mesh stone powder. The models are complete and the categories are rich.
