Entrusted by one of graphite ore plant client in Kra, Vietnam, Xinhai undertook the project of graphite ore processing. According to the result of mineral processing experiments, Xinhai professional team, after much discussion and selection, decided to apply Cylinder Energy-Saving Overflow Type Ball Mill (MQYG 153), which achieved the target of cost control and improved the grinding efficiency.
With a trumpet-shaped outlet and annular retaining ring, this ball mill is high efficiency in discharging. In manufacturing the straight cylinder energy saving overflow type ball mill, Xinhai makes a trumpet-shaped of hollow shaft neck end in ore discharge end. At the same time, in the hollow shaft of the root is mounted a ring-shaped retainer, which prevents pulp spilling out though bolt hole flow into inner bearing. The discharge pipe is casted with the spiral line, the spiral direction is opposite to the grinding machine. So as to prevent the steel balls and ore discharge out of the machine along with the pulp.
With large double-row spherical roller bearings and a wave-shaped lining plate. This ball mill applies large double-row spherical roller bearings instead of a sliding bearing. The friction force is greatly reduced. And start easily, energy saving by 20 -30%. The cylinder body adopts a wave-shaped lining plate, which increases contact surface of the steel ball and the graphite and also reduces the energy consumption;
The grinding time is long, and high precision of the finished product. Due to relative long grinding time of energy-saving overflow type ball mill, graphite ore can fully be grinded in the machine. In that way, the residence time is long and the grinding product is thin. The particle size can meet the requirements of the client. Thus as the mining stage grinding, it is applicable to concentrate regrinding operation. Thereby we can obtains a finer particle size acceptable product.
The dressing test mainly recycled graphite. The test sample was taken by the trusted party, and served to or company. Our team tested the sample. the raw ore, through a nine-stage grinding, one time of roughing, primary scavenging, nine times of concentration, was possible to obtain a yield of 14.20%, and the fixed carbon content was 92.30%, which got the recovery rate of 87.91% about graphite concentrate.
finally, according to the nature of the ore and ore feasibility study report, Xinhai determined the item by a two-stage closed-circuit crushing process, a section of the closed circuit grinding grading process and a coarse-scanning, the ten times of fine flotation process flow, and finally reacheds the standard for production target, our client was very satisfied.
