Problems solved by technology

[0002] At present, calcium and magnesium fertilizers are mostly liquid fertilizers, which are expensive to prepare, bulky, inconvenient to transport, and liquid inconvenient to store
When applying liquid calcium and magnesium to plants, it is based on the principle of low concentration and a small amount of multiple times to increase the plant's need for calcium and magnesium. Therefore, liquid calcium and magnesium fertilizers cannot continuously provide calcium and magnesium ions for their absorption during the entire production process of plants.
For ordinary bulk fertilizers, in addition to the large volume, there is also the disadvantage of uneven shape, which is not conducive to storage. In addition, due to the uneven size of the volume, it is not convenient to weigh and measure according to the actual required amount during use. use
Moreover, due to the large volume of bulk fertilizer, it is not conducive to dissolution in the soil, which affects the absorption of nutrients by plants
For granular fertilizers, the volume is too small, and there are defects such as easy deliquescence

Abstract

The invention discloses a production technology of flaky calcium-magnesium fertilizer, which comprises the following steps in sequence: (1) heating and stirring calcium nitrate, magnesium nitrate and a chelate microelement in a heating tank to obtain a uniform molten material; (2) pumping the material out of the heating tank by a pumping device, conveying the material to a group of spray nozzles, and spraying the molten material from the spouts of the spray nozzles; (3) placing a moving steel belt for refrigerating under the spouts of the spray nozzles to solidify the material instantly; and (4) conveying the material to a scraper collecting device through the moving steel belt, wherein the collected material is the flaky calcium-magnesium fertilizer. The invention further provides special production equipment for the production technology. The production technology is convenient and fast, and can be used for preparing the flaky solid calcium-magnesium fertilizer under the condition of preserving fertilizer nutrients to the maximum extent; and the flaky calcium-magnesium fertilizer is convenient to store and transport and can be used as base fertilizer to continuously provide calcium-magnesium ions and other nutrients for plants.
