Embodiment 1
[0055] Grind shale into shale powder, then select silt, dewatered sludge and shale according to the weight percentage of each raw material in Example 1 of the above table 1, and then put them into a wheel mill for mixing and homogenization, and mix well The chemical treatment time is 10 minutes. After mixing the materials uniformly, they are placed and stacked for aging for 5 days at normal temperature, and partially dehydrated to obtain the mixed materials;
[0056] The mixture obtained above is first extruded through an extruder, and then granulated to form granules. After being extruded through an extruder, granulated, the obtained granules have higher density. The granulation adopts secondary granulation. For the first time, the roller granulation is used for 5 minutes, and for the second time, the granulation roller is used for 4 minutes. The particle size of the material after the secondary granulation is 5-10mm; Carry out double-roll granulation on the double-roll machi...
Embodiment 2
[0059] Grind shale into shale powder, then select silt, dewatered sludge and shale according to the weight percentage of each raw material in Example 2 of Table 1 above, and then put them into a wheel mill for mixing and homogenization, and mix well The chemical treatment time is 15 minutes. After mixing the materials uniformly, they are left to be stacked and aged for 7 days at normal temperature, and partially dehydrated to obtain the mixed materials;
[0060] The mixture obtained above is first extruded through an extruder, and then granulated to form granules. After being extruded through an extruder, granulated, the obtained granules have higher density. The granulation adopts secondary granulation. For the first time, the roller granulation is used for 5 minutes, and for the second time, the granulation roller is used for 4 minutes. The particle size of the material after the secondary granulation is 5-10mm; Carry out double-roll granulation on the double-roll machine, a...
Embodiment 3
[0063] Grind shale into shale powder, then select silt, dewatered sludge and shale according to the weight percentage of each raw material in Example 3 of the above table 1, and then put them into a wheel mill for mixing and homogenization, and mix well The chemical treatment time is 15 minutes. After the materials are mixed evenly, they are stacked and aged at room temperature for 7 days, and partially dehydrated to obtain the mixed material; the moisture content of the mixed material is 18% to 22%.
[0064] Extrude the above-mentioned mixed material with a water content of 18% to 22% through an extruder, then granulate to form material granules, first extrude through an extruder, and then granulate to obtain the material The granulation density is higher, the granulation adopts the secondary granulation, the first time adopts the roller granulation for 5 minutes, and the second time adopts the granulation roller granulation for 4 minutes, the material granulation after the se...
