Embodiment Construction

[0011] Below in conjunction with embodiment the present invention is described in further detail.

[0012] A calcium-enriched sand made of calcium-increased coal slag from a cyclone boiler is characterized in that: the nominal particle size of the calcium-enriched sand is 80 μm to 5.00 mm, and the fineness modulus is gradation of 0.7 to 3.7.

[0013] The second technical solution to realize the object of the present invention is: crush the imported calcium-increasing cinder with a crusher, and then sieve the crushed calcium-increasing cinder with a screening device with a nominal diameter of sieve hole of 80 μm to 5.00 mm, In order to obtain calcium-enriched sand with a nominal particle size of 80 μm to 5.00 mm. Unqualified products after screening can be returned for re-crushing.

[0014] Moreover, the crusher is a ball mill or a straight-through impact crusher.

[0015] The 3rd technical scheme that realizes the object of the present invention is: prepare concrete with it,...

Abstract

The invention relates to calcium increased sand made of cyclone boiler calcium increased cinder, which is characterized in that: the nominal diameter of the calcium increased sand is 80Mum to 5.00mm and the fineness modulus thereof is 0.7 to 37 gradation. The invention adopts another technical proposal that: a method for preparing the calcium increased sand by using the cyclone boiler calcium increased cinder is characterized in that: the input calcium increased cinder is crushed by using a crusher, and the crushed calcium increased cinder is subjected to screening processing by using screening equipment with the nominal diameter of sieve holes being 80Mum to 5.00 mm so as to obtain the calcium increased sand with the nominal diameter of 80Mum to 5.00mm. The invention can be used for preparing concrete or mortar, thus leading wastes of a field to become resources of another field.

Description

technical field [0001] The invention relates to calcium-enriched sand made from calcium-increased coal slag of a cyclone boiler, a preparation method and application thereof. Background technique [0002] With the increasing demand for energy, the industrial waste residue fueled by coal has increased rapidly, which has seriously affected the ecological environment. On the other hand, with the continuous increase of the amount of sand used in construction, massive sand mining poses a serious threat to the safety of river embankments. How to effectively increase the effective utilization of industrial waste and reduce environmental pollution has become an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a kind of sand made of cyclone boiler calcium-increased coal slag and its preparation method and application, which can provide an effective way for the harmless utilization of fuel industrial waste residue, an...
