Abstract
The invention provides a process for calcining a soil conditioner by using a rotary kiln, which belongs to the technical field of soil conditioner production and comprises the following preparation steps: step one, ore type: potassium feldspar, limestone and dolomite; step two, crushing of ores: performing primary crushing treatment on the ore in the first step to obtain crushed stone with the diameter of 1.5-2.5 cm, performing secondary crushing treatment on the ore to obtain small crushed stone with the diameter of 0.3-0.7 cm, and finally performing tertiary crushing treatment on the ore to obtain ore particles with the diameter of 0.3-0.5 mm; step three, calcining the ore: firstly, continuously feeding ore particles from a furnace mouth of a rotary kiln; secondly, heating up to preheat the ore particles and the rotary kiln; thirdly, calcining at 1200-1300 ℃ for 35-40 min; cooling to reduce the temperature of the ore, and keeping the temperature to be more than or equal to 500 ℃; the invention can reduce the waste of resources, is more environment-friendly and green, improves the calcining process and reduces the reduction of potassium ions.
Description
Technical Field
The invention relates to the technical field of soil conditioner production, in particular to a process for calcining a soil conditioner by using a rotary kiln.
Background
The soil amendment utility principle is to bind many small soil particles to form large, water-stable aggregates. The method is widely applied to the aspects of preventing soil from being eroded, reducing water evaporation or excessive transpiration of the soil, saving irrigation water and promoting healthy growth of plants;
however, when the ore is calcined in the conventional calcining process, the melting and calcining are mostly performed by using a barrel furnace, so that not only is the electric power extremely wasted, but also the cooled ore is adhered to the inner wall of the barrel furnace, and small-scale blasting is required to be performed to remove the adherent ore, and the barrel furnace wastes a large amount of heat due to the operation, so that the barrel furnace is not environment-friendly and pollutes the environment, and the reduction of calcium and potassium ions often occurs after the calcined ore powder particles are used, so that the potassium salt is reduced.
Disclosure of Invention
In view of the above, the invention provides a process for calcining a soil conditioner by using a rotary kiln, which can reduce resource waste, is more environment-friendly and green by using the rotary kiln, and reduces reduction of potassium ions by improving a calcining process.
In order to solve the technical problems, the invention provides a process for calcining a soil conditioner by using a rotary kiln, which comprises the following preparation steps:
step one, ore type: potassium feldspar, limestone and dolomite;
step two, crushing of ores: performing primary crushing treatment on the ore in the first step to obtain crushed stone with the diameter of 1.5-2.5 cm, performing secondary crushing treatment on the ore to obtain small crushed stone with the diameter of 0.3-0.7 cm, and finally performing tertiary crushing treatment on the ore to obtain ore particles with the diameter of 0.3-0.5 mm;
step three, calcining the ore: firstly, continuously feeding ore particles from a furnace mouth of a rotary kiln;
secondly, heating up to preheat the ore particles and the rotary kiln;
