A crush-resistant and drop-resistant lime powder ball and its preparation method
A technology of lime powder and fiber, applied in the field of anti-shattering and anti-shattering lime powder balls and its preparation, can solve the problem that the lime powder balls have low crush resistance, drop resistance and wear resistance, which affect the recycling of lime powder balls, and are easily damaged. Problems such as pulverization, to achieve the effect of low cost, more recycling times, and less fiber addition

Embodiment 1
[0028] Embodiment 1: An anti-shattering and anti-shattering lime powder ball is characterized in that: it contains the following raw materials in parts by weight:
[0029] 0.01 parts of fiber with a thickness of 1.5 dtex and a length of 1 mm and 100 parts of lime powder with a particle size of less than 3 mm;
[0030] Concrete preparation steps are as follows:
[0031] a. Raw material mixing: add 0.01 parts of fiber and 100 parts by weight of lime powder into a twin-shaft mixer, stir at room temperature, mix evenly, and rotate at a speed of 5r / min;
[0032] b. Preparation of lime powder balls: the uniformly mixed material in step (a) is pressed into a 30mm lime ellipsoid through a roller-type high-pressure briquetting machine with a linear pressure ratio of 0.8t / mm.
[0033] The crushing and falling strength of lime powder balls prepared by adding fibers can be increased by 5 times compared to the reference sample without adding fibers.

[0042] Embodiment 3: an anti-shattering and anti-shattering lime powder ball, characterized in that: it contains the following raw materials in parts by weight:
[0043] 0.14 parts of fiber with a thickness of 8 dtex and a length of 10 mm and 100 parts of lime powder with a particle size of less than 3 mm;
[0044] Concrete preparation steps are as follows:
[0045] a. Raw material mixing: Add 0.14 parts of fiber and 100 parts by weight of lime powder into a twin-shaft mixer, stir at room temperature, mix evenly, and rotate at a speed of 70r / min;
[0046]b. Preparation of lime powder balls: the uniformly mixed materials in step (a) are pressed into 50 mm lime ellipsoids through a roller-type high-pressure briquetting machine with a linear pressure ratio of 0.9 t / mm.
[0047] The crushing and falling strength of lime powder balls prepared by adding fibers can be increased by 8.5 times compared to the reference sample without adding fibers.
