Preparation method of low-density high-strength ceramsite proppant
The invention relates to the field of ceramsite proppants, in particular to a preparation method of a low-density high-strength ceramsite proppant. The preparation method comprises the following steps: weighing raw materials for subsequent use, feeding the raw materials into a factory, carrying out jaw crushing, and carrying out ball crushing; carrying out fine crushing and grading treatment on coarse particles of the raw material, and then feeding the raw material into a ball bin; respectively stacking the raw materials according to varieties, and carrying out detecting; proportioning and premixing required main materials and auxiliary materials through an automatic proportioning system according to a formula ratio, and performing forced mixing and humidifying mixing; allowing the humidified and mixed fine powder raw materials to enter a double-roller extruder for extrusion twice and then to enter a depolymerization machine for depolymerization; and adding various uniformly mixed finepowder raw materials into a ball forming mill for ball forming, and spraying vaporous water drops into the ball forming mill via an efficient water spraying device while the ball forming mill continuously performs circular rotating motion so as to form semi-finished ceramsite sand. The preparation method is reasonable in proportion and simple in process, and the prepared ceramsite proppant resistant to high temperature and high pressure, high in strength and high in corrosion resistance.
本发明涉及陶粒支撑剂领域，具体涉及一种低密度高强度陶粒支撑剂的制备方法，取原料备用，将上述原料原料进厂后先进行鄂式破碎，再进行球破粉碎；对原料粗颗粒进行细粉碎及分级处理后进入球仓；各种原料按品种分别堆放，并进行检测；将所需主料、辅料按照配方比例经过自动配料系统进行配料预混合后，再进入强制混合及加湿混合；加湿混合后的细粉原料进入对辊挤压机挤压两遍后进入解聚机进行解聚；经过拌均匀的各种细粉原料，加入成球机进行成球，在成球机不断进行圆周旋转运动的同时，由高效喷水装置向志球机内喷出雾状水珠形成半成品陶粒砂；本发明配比合理，工艺简单，陶粒支撑剂耐高温、高压，强度高、耐腐蚀性强。
