Embodiment 1
[0024] Example 1 A suspension filter material for removing iron and manganese, which is composed of the following components in parts by weight:
[0025] Manganese sand 650 parts;
[0026] 80 parts of expanded perlite;
[0027] 20 parts of plastic particles.
[0028] The preparation method of the suspension filter material for removing iron and manganese is as follows:
[0029] a. Weigh raw materials
[0030] Weigh 650 grams of manganese sand with a particle size of 1-3mm and a manganese content greater than 40% by weight; ②a particle size of 1-3mm and a specific gravity of less than 200kg / m 3 80 grams of expanded perlite, ③ 20 grams of plastic particles (PE particles) with a melting point of less than 125 ° C and a particle size of 1-3 mm;
[0031] b. smash
[0032] Put the three raw materials into the pulverizer independently and pulverize them fully so that the particle size is 0.5mm;
[0033] c. Mix well
[0034] Feed manganese sand, expanded perlite and crushed pla...
