Product Description

Vero ball clay: the top ball clay in the world By experts’ research and feasibility studies proved that the vero ball clay in Jiangxi town, Nanning of Guangxi to the physical and chemical indicators of ball clay are slightly higher than the ball clay in U.S and UK. With high plasticity, strong adhesions, fine particles of composing that are superior to other types of clay products. Also on high strength drying, sintering range, high-temperature sintering without cracking characteristics, vero ball clay is known at home and abroad. Its performance can be compared with the United States, the United Kingdom similar products; so call it world-class ball clay. Vero ball clay which made in Vero slope, Tongliang village, Jiangxi county of Nanning City, commonly known as Pak Nai, formerly known as kaolin, also known as fire-resistant clay. Vero ball clay contents for the disordered kaolinite (*0% **5%), followed by quartz (<*0%) and trace amounts of ilmenite material. Mineral particles content in small*2μm particles greater than *0%, some up to *5% of ore block, in which kaolinite particle size less than 2μm, the average particle size is 0.*8μm. Ore plasticity index greater than *5, usually ****5, can reach *7, refractoriness to ***0 ℃ ****0 ℃. The chemical composition of ore: SiO2 *4% **3%, AL2O3 *8% **7%, Fe2O *0.**2%, MnO <0.*1CaO + MnO + K2O + Na2O <1.2. Second, vero ball clay also has a good rheology, dispersion, thixotropy. Vero ball clay is a kind of high quality clay in domestic or the world. Primary purpose of Vero ball clay: 1. Use for unshaped refractories: clay with common, high-strength, lightweight materials, can be plasticsing, gunning, ramming materials, clay, mud ***** and for other fine bubble ceramic binder, plasticizer, sintering agent; 2. Use for setting refractories: high quality in low stomatal and low creep, special-shaped brick, high anti-peeling alumina bricks, low iron light insulating brick, clay brick with SiC crucible, burning free bri
