Embodiment 1
[0078] Such as figure 1 The shown cement clinker preparation method based on oxidized vanadium tailings comprises the following steps:
[0079] S1, weighing raw materials in proportion;
[0080] S2. Use the crushing mechanism to crush the raw materials, and make the crushed raw materials enter the grinding mechanism;
[0081] S3. Use the grinding mechanism to grind and mix the raw materials, and make the ground raw materials enter the filtering mechanism;
[0082] S4. Use a filtering mechanism to filter and dry the ground tailings at the same time;
[0083] S5. Calcining the dried raw materials at 1400-1420° C. for 50-80 minutes, and obtaining cement clinker after cooling.
Embodiment 2
[0085] On the basis of the cement clinker preparation method for oxidized vanadium tailings described in Example 1, the raw materials include the following components in terms of mass percentage: 50% to 70% of limestone, 10% to 15% of oxidized vanadium tailings %, clay 6% to 8%, and the balance as adjuvants.
[0086] In this embodiment, the adjuvant includes the following components in mass percentage: phosphogypsum:activator=5:1.
[0087] The formula of this embodiment is drawn by the applicant after a lot of research and experiments, and the experimental production is carried out with this formula, and the obtained cement clinker has the following properties:
[0088]
[0089] It can be seen that the cement clinker obtained in this example can meet the strength requirements, and its early strength performance is relatively strong, and the compressive strength at 72 hours can reach 38.83MPa, which is superior in early strength performance and is more suitable for those wit...
Embodiment 3
[0091] Based on the cement clinker preparation method of vanadium tailings produced by oxidation, on the basis of any of the above-mentioned embodiments, the crushing mechanism used in this embodiment is as follows figure 2 and image 3 As shown, it includes a crushing box 31, and one end side wall of the crushing box 31 along the long axis direction is set as an openable baffle 32; the inside of the crushing box 31 is slidingly fitted with a push plate 33, and the push plate 33 is driven by The mechanism is driven to slide, and the sliding direction of the push plate 33 is along the long axis of the crushing box 31; a number of crushing cones 34 are arranged on the side surface of the push plate 33 facing the direction where the baffle plate 32 is located. Both opposite side walls of the crushing box 31 are provided with chute 35 parallel to the long axis, and the two ends of the push plate 33 are respectively slidably connected to the chute 35 on both sides. The driving me...
