Abstract
The invention belongs to the technical field of chemical production, and particularly relates to a manufacturing method of calcium superphosphate. The manufacturing method comprises the five steps of selecting materials, grinding minerals into powder, stirring for mixing, curing by pile-turning, and crushing. The calcium superphosphate produced by the invention can effectively provide a phosphate fertilizer and a calcium fertilizer required by growth of crops, the loss of the phosphate fertilizer and the calcium fertilizer is reduced to the minimum, time for providing the phosphate fertilizer and the calcium fertilizer to crops is prolonged, the cost is reduced for farmers, and crops grow better.
Description
Technical field
The invention belongs to chemical production technology field, be specifically related to a kind of making method of general calcium.
Background technology
At present, Rock Phosphate (72Min BPL) and sulfuric acid mixing slaking are a kind of common methods of producing general calcium.The general calcium produced is Powdered or is particulate state.During with pulverous general calcium fertilising, it is fast that effect released by phosphate fertilizer, and especially after rain drop erosion, phosphate fertilizer runs off serious, and Crop is few, and effect is impermanent.When utilizing granular general calcium fertilising, it is slow that effect released by phosphate fertilizer, is not enough to provide Crop to grow, do not have due effect.
Summary of the invention
For solving above technology Problems existing, the invention provides a kind of making method of general calcium, wherein both containing granular general calcium, also containing pulverous general calcium, effectively can be supplied to the phosphate fertilizer that plant growth needs for a long time, both can instant effect, again can long sustaining fertilizer efficiency.
Its technical scheme is:
A making method for general calcium, carry out according to following steps:
(1) select materials: choose ferric oxide and the higher Rock Phosphate (72Min BPL) of alumina content is for subsequent use, the ferro element in Rock Phosphate (72Min BPL) and aluminium element total mass account for the 7-10% of Rock Phosphate (72Min BPL) total mass;
(2) ore grinding powder: the Rock Phosphate (72Min BPL) chosen is broken into Powdered;
(3) be uniformly mixed: in rock phosphate powder, add excessive sulphuric acid soln, after being uniformly mixed fully, forming slip;
(4) slaking turning: slip is placed on natural air drying solidification in normal temperature environment, carries out a turning operation for ten days, altogether turn over 2 ~ 3 times;
(5) broken: after slaking turning terminates, block fragmentation dispersion will be expected through crusher.
Further, described Rock Phosphate (72Min BPL) is calcium superphosphate.
Iron in Rock Phosphate (72Min BPL) and aluminium and sulfuric acid can react and generate ferric sulfate and Tai-Ace S 150.In slaking turning process, ferric sulfate and Tai-Ace S 150 can be evenly distributed between general calcium, wrap general calcium.After crusher dispersion, form granular general calcium, and just do not powdered by the general calcium of ferric sulfate and Tai-Ace S 150 parcel.In general Rock Phosphate (72Min BPL), iron and aluminium content are lower than 7%, and according to this area common slaking turning operation, the general calcium of formation is Powdered.In Rock Phosphate (72Min BPL), iron and aluminium content are higher than 10%, and according to this area common slaking turning operation, the general calcium of formation is particulate state.In Rock Phosphate (72Min BPL), iron and aluminium content are between 7%-10%, and according to slaking turning operation of the present invention, the general calcium of formation is particulate state and pulverous mixture.Ferric sulfate and Tai-Ace S 150 water insoluble, but slowly can be decomposed by field bacterium.General calcium containing powder and particle is imposed on field, and Powdered general calcium decomposes provides phosphate fertilizer and calcareous fertilisers, meets the growth demand of crop.Meanwhile, ferric sulfate and the Tai-Ace S 150 on granular general calcium surface are slowly decomposed by field bacterium always, and after treating that Powdered general calcium is released and imitated, the phosphate fertilizer in granular general calcium and calcareous fertilisers start to decompose, and provide phosphate fertilizer and calcareous fertilisers, meet the growth demand of crop.
Beneficial effect of the present invention:
The general calcium that the present invention produces effectively can provide phosphate fertilizer needed for plant growth and calcareous fertilisers, and phosphate fertilizer and calcareous fertilisers loss are down to minimum, and the phosphate fertilizer provided for crop and calcareous fertilisers time lengthening, save the cost of peasant, makes plant growth better.
Embodiment
