Abstract
The invention discloses a method for preparing a soil conditioner by utilizing steel slag, belonging to the field of comprehensive utilization of resources, and comprising the following five steps: screening, burdening, mixing, pelletizing and bagging. The method for preparing the soil conditioner by utilizing the steel slag is characterized by screening out steel slag with the size less than 3 mm, burdening 25-40 wt% of the steel slag and 75-60 wt% of vinegar residue, mixing, and utilizing a cylindrical pelletizer to carrying out pelletizing and granulating. The invention can process the steel slag in large scale, improves soil fertility, improves crop output and quality, has low manufacture cost and realizes the purpose of industrially using waste to treat waste.
Description
Technical field:
The invention belongs to the comprehensive utilization of resources field.
Technical background:
Along with growing continuously and fast of iron and steel output, metallurgical slag rolls up, and gives the pressure of iron and steel enterprise more and more heavier, also brings huge load for environment.Though slag can reach the purpose of recycle by producing slag micro powder, because the hardness of slag is big, the abrasion resistance index height, the energy consumption height, course of processing cost is big, and economic benefit is not remarkable; Slag is used to pave the way and aspect such as building materials,, limited consumption and purposes because the existence of f-CaO causes problems of crack.How using slag, turn waste into wealth, is our urgent problem.
Summary of the invention:
In order to widen the approach of steel slag utilization, the invention provides a kind of method of utilizing slag to make soil conditioner.
The present invention includes screening, batching, mixing, granulation, five steps of pack, it is characterized in that with sieve out＜slag of 3mm is that 75-60% prepares burden for 25-40% Cu Zao weight percent by weight percentage, mix the back with drum pelletizer make ball, (requiring granularity is 2～5mm) in granulation.
The present invention can handle slag in a large number, improves the fertility of soil, improves output and the quality of farm crop, and cost of manufacture is low, realizes the industrial treatment of wastes with processes of wastes against one another.
Embodiment:
Embodiment: slag is sieved, and the slag of granularity＜3mm 30% ， Cu Zao weight percent by weight percentage is 70% to prepare burden, and confected materials is mixed the back make ball, granulation, pack with drum pelletizer.
Cu Zao be make after the vinegar surplus residue.
Claims (2)
1. utilize slag to make the method for soil conditioner, comprise screening, batching, mixing, granulation, five steps of pack, it is characterized in that with sieve out＜slag of 3mm is that 75-60% prepares burden for 25-40% Cu Zao weight percent by weight percentage, mix the back and make ball, granulation with drum pelletizer.
2. the method for utilizing slag to make soil conditioner according to claim 1 is characterized in that the granularity of granulating is 2～5mm.
