Lattice-type ball mill

Lattice type ball mill is the material being broken, the further key equipment for grinding. It is widely used in mineral processing, construction and chemical industries, such as in cement, silicate products, new building materials, refractory, chemical fertilizer, black and non-ferrous metal ore-dressing and glass ceramics and other production industries, for a variety of ores and other materials can be carried out dry grinding or wet grinding.

Lattice Ball mill of Longding has the following advantages：

1. The hollow axis adopts the cast steel and the lining can replace, the rotating big gear processes in the way of casting rolling gear. The barrel body is wearable well and bears wearable scale board.

2. The machines run steadily and work reliably, low operating cost

3. Big crushing ratio, uniform final product size

4. It uses the whole rack, easy to civil construction and equipment installation.

5. It has taken out the material side cone design, which not only increased the volume, but also forcing cone side of the ball classification, the more near the exit, the smaller diameter steel ball, increasing the role of repeated grinding, then the fine material degree of further improved. 

格子型球磨机

格子型球磨机是被打破的材料，进一步研磨的关键设备。它广泛应用于水泥，硅酸盐制品，新型建筑材料，耐火材料，化肥，黑色与有色金属选矿以及玻璃陶瓷等生产行业，对各种矿石和其它材料，可进行干磨或湿式粉磨。

1.该球磨机传动采用滚动轴承代替滑动轴承，摩擦力大大降低，起动容易、节能显著；
2.它的出料端采取了锥体设计，这样既增加了容积，又迫使锥体端的钢球分级，愈接近出口，钢球直径愈小，增加了反复研磨的作用,便物料的精细程度进一步提高；
3.它采用沟槽式环型衬板，增加了球矿接触表面，加强了研磨作用，且对矿石有提升能力，降低了功率；
4.  中空轴采用铸钢和衬里可替代铸造轧齿轮，桶身是耐磨和耐耐磨衬板
5. 机器运行稳定，可靠地工作, 运行成本低

6.破碎比大，最终产品大小均匀
