Embodiment 1

[0033] Embodiment 1: This embodiment provides a ceramsite sand with olivine added, including the following raw materials in weight percentage: bauxite 45wt%, burnt gem 40wt%, olivine 7wt%, magnesium slag 3wt%, manganese ore powder 5wt% .

[0034] Preparation Process:

[0035] Step 1. Ingredients: Weigh the bauxite, burnt gem and olivine according to weight percentage, pour them into a ball mill for grinding and pass through a 325-400 mesh sieve, then grind the magnesium slag and manganese ore powder through a 400 mesh sieve.

[0036]Step2. Mixing and granulation: Pour the sieved powder into the mixer and mix at a speed of 1800-2000 r / min for 10-30 minutes, then mix at a speed of 1200-1500 r / min for 10-30 minutes, and During the mixing process, 5% of the total weight of raw materials is sprayed into highly atomized water to obtain a mixture, and the mixture is sent to a granulator for granulation, and semi-finished embryos of different particle sizes are obtained after passing...

Embodiment 2

[0046] Embodiment 2: On the basis of Embodiment 1, a kind of ceramsite sand with olivine added in this embodiment, the difference is that the raw materials used are bauxite 50wt%, burnt gemstone 35wt%, olivine 10wt%, magnesium Slag 3wt%, manganese ore powder 2wt%.

[0047] Preparation Process:

[0048] Step 1. Ingredients: Weigh bauxite, burnt gem and olivine according to weight percentage, pour them into a ball mill for grinding and pass through a 325 mesh sieve, then grind the magnesium slag and manganese ore powder through a 400 mesh sieve.

[0049] Step2. Mixing and granulation: Pour the sieved powder into the mixer and mix at a speed of 1800-2000 r / min for 10-30 minutes, then mix at a speed of 1200-1500 r / min for 10-30 minutes, and During the mixing process, 5% of the total weight of raw materials is sprayed into highly atomized water to obtain a mixture, and the mixture is sent to a granulator for granulation, and semi-finished embryos of different particle sizes are ob...

Embodiment 3

[0053] Example 3: The difference from Example 1 is that the ceramsite sand added with olivine provided in this example is different in that the raw materials used are bauxite 55wt%, burnt gem 30wt%, olivine 12wt%, Magnesium slag 2wt%, manganese ore powder 1wt%.

[0054] Preparation process: Step1, ingredients: Weigh bauxite, coke gem and olivine according to weight percentage, pour them into a ball mill for grinding and pass through a 325-400 mesh sieve, then grind magnesium slag and manganese ore powder through a 400 mesh sieve .

[0055] Step2. Mixing and granulation: Pour the sieved powder into the mixer and mix at a speed of 1800-2000 r / min for 10-30 minutes, then mix at a speed of 1200-1500 r / min for 10-30 minutes, and During the mixing process, 5% of the total weight of raw materials is sprayed into highly atomized water to obtain a mixture, and the mixture is sent to a granulator for granulation, and semi-finished embryos of different particle sizes are obtained after ...

Abstract

The invention relates to the technical field of new materials, in particular to olivine-added lightweight ceramsite sand and a preparation process thereof. The lightweight ceramsite sand comprises thefollowing raw materials in percentage by weight of 45-55 wt% of bauxite, 30-40wt% of flint clay, 7-12wt% of olivine, 1-6 wt% of magnesium slag and 1-5 wt% of manganese ore powder, wherein the bauxiteis the medium-low grade bauxite; the medium-low grade bauxite is used as the main material, so that the vacancy of high bauxite shortage is filled, and the medium-low grade bauxite is reasonably utilized; and during preparation, the rotating speed of a mixer in preparation is controlled to help form a semi-finished blank ball with high sphericity, so that the ceramsite sand with excellent mechanical property is prepared.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to light ceramsite sand added with olivine and a preparation process thereof. Background technique: [0002] During the deep mining of oil and natural gas, the high closure pressure and low permeability deposits are fractured to crack the oil-gas-bearing rock formations, and the oil and gas are collected from the channels formed by the cracks, and the high-aluminum support materials are used to enter the formation with the high-pressure solution to fill the formation. In the fracture, it plays the role of supporting the fracture from being closed due to pressure release, so as to maintain high conductivity, make oil and gas unblocked, increase production, and extend the service life of oil and gas wells. [0003] Proppant, as a key material for oil and gas fracturing construction, is a high value-added product. Its performance determines the success of fracturing t...
