试验室XMQL型密封式连续带筛球（棒）磨机技术参数
Technical Parameters of Laboratory Sealed Ball（rod）Mill with Screen

XMQL连续带筛球磨机是一种半工业型干式磨矿设备，它是按克鲁伯型球磨机的原理设计制造的，筒体外周装有两层筛网（一层粗筛、一层细筛），磨细物料在磨机运转中，穿过筒体内的出料口，再经筛网排出，筛上的物料从回料口返回筒体再磨。本产品由原地矿部唯一指定企业生产，执行行业标准。

该机配有电磁振动给料机，给料均匀，从给料到磨料均采用密封罩密封。磨样时间液晶屏莫菜单显示，任意设置，存储磨棒标准值。

本机的主要特点：具有国外同类型产品的优点，磨样作业和分筛在一机上同时完成；磨矿效率高，能避免物料过度粉碎和磨矿不足等现象，产品粒度均匀，且为颗粒状。出料粒度可控制，通过选配一定目数的筛网，将出料粒度控制在预定的粒度范围内。同时有良好的密封性，在磨矿过程中可实施惰性气体保护，防止物料氧化和自燃等现象。产品结构紧凑、噪音小。该机可用于铁锰矿石、有色金属矿石、水泥、耐火材料、炉渣、陶瓷建材、化工等脆性材料粉磨。特别适合稀土钕铁硼和镍氢电池、储氢合金粉加工防氧化工艺要求。

XMQL Model Laboratory Sealed Ball Mill with Screen is a semi-commercial dry grind equipment and designed , manufactured on the basis of philosophy of Krupp Type Ball Mill. The cylinder periphery is fitted with two layers of screen mesh ( one layer of coarse screen and one layer of fine screen). In the operation of the ball mill, the fine materials pass through the outlet of cylinder before being discharged via screen mesh. The oversize materials from feedback inlet go back to the cylinder for regrinding. The product is produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

The machine is complete with electromagnetic vibrating feeder with uniform feeding. Sealing is made with sealing cover from the section of feeding to grinding operations.

Main features of the machine; with advantages of the same type of foreign products; sample grinding and screening operations being conducted on the machine at the same time; high efficient ore grinding avoidance of occurrence of excessive crushing of materials, inadequate ore grinding and others; uniform granular product size; controllable vent material size; control of vent material sizes within the preset range by selecting a certain number of screen meshes; good sealing performance.

inertia gas protection in the grinding process to prevent oxidation of material and spontaneous combustion,etc. The product is compact in structure with lower noise. The machine can be applied to grinding of iron manganese ore, nonferrous metallic ore, cement, refractory material ,slag, ceramic building material, chemical material and other brittle materials and is especially suitable for processing rare earth neodymium-iron-boron, nickel –hydrogen battery, hydrogen storage alloy powder, which require involvement of anti-oxidation technology.
