1、长沙坚韧机械有限责任公司Changsha jianren machinery Co., Ltd 吴丽文13647480488地址：湖南省长沙县经济技术开发区天华南路 1Single transmission roller machineThe first choice of pre-grinding procedure in cement industryIn the traditional proceduce of cement pre-grinding,The cost of crusher machine was cheap but with very low efficiency.Th
2、e cost of ball crusher was also expensive with high energy consumption.The roller machine was developed in the middle of 1980s,Its a new type of grinding machine in cement industry with energy-saving.It also can be replaced with part or most part of ball crushing machine system.Moreover,the advantag
3、e is low cost and noise.The maine application of this machine is for technical upgrade of old plant and also for new building of plant.The advantage of dual-drive roller machine is more efficiency in mass production but the disadvantage is higher investment and energy consumption.For this purpose,th
4、e Changsha Jianren Machinery Co., Ltd developed the single transmission roller machine on his own.It can increase the efficiency in mass production to 40100%,it also can increase more than 45% of energy-saving after comparing with dual-drive roller machine and reduce the investment by one in third.
5、The fine material with OD less than 0.08mm takes up 30% and the fine material with OD less than 2mm takes up 80%,It will cause full of many small cracks in internal structure and have more and better grindability.The roller surface is treated with heat welding and will be very easily to maintenance.
6、This kind of single transmission roller machine is competitive in market and has a lot of praise from users,we also achieved national patent (patent number: 200720063684.5).The 1st , The mechanism of single transmission roller machineThe mechanism is high pressure and crushing in the same time.The s
7、ame between single transmission roller machine and dual-drive roller machine is: There is one fixed roller and movable roller in the machine and the speed is the same for both roller and they are operated in relative way, the material is from the upper feed port into the high pressure in the two-rol
8、l gap and has been crushed and shattered. The difference between single transmission roller machine and dual-drive roller machine is that the single transmission roller machine has been powered only by the fixed roller transmission with low power consumption,the movable roller is drived by fixed rol
9、ler through dentition and can achieve the complete of synchronization so that it can solve the shortcomings of severe wear due to sliding extrusion roll; The pressure adjustment system is made by a combination of spring with low failure rate; The material size (with screening) 0.08mm is up to 30%, t

15、ts made by alloy stack welding and the hardness is around HRC60-63,the hardness is higher than which made by forging parts; The spring pressure is slightly lower than the hydraulic pressure, not only to crush purpose but also protect the roller surface from being danaged; Therefore, the life time is
16、 much longer than the dual-drive roller.5、It also can be chosen with optional V-shaped separator machine or new rotary filter, the sorting rate can be reached to 90%.The 3rd ,The main technical parameters of single transmission roller machine(The sample analysis report of material DG1200*500 from so
