Guide: Recently, Zoomlion's first 70t drying cylinder independently developed and designed was successfully commissioned in Hanshou Industrial Park. This drying cylinder is by far the largest drying cylinder of Zoomlion, marking that Zoomlion's dry mixed mortar technology has risen to a new level. 70t drying drum is the most advanced in China

recently, Zoomlion's first 70t dryer independently developed and designed was successfully debugged in Hanshou Industrial Park. This dryer is by far the largest dryer of Zoomlion, marking that Zoomlion's dry mixed mortar technology has risen to a new level

70t drying drum adopts the most advanced "three return technology" in China, which can accommodate 60t-70t materials for drying at the same time. Compared with the traditional single barrel dryer, the thermal efficiency of 70t dryer is increased by more than 40%. Compared with 50t dryer, 70t dryer is more advanced. First of all, the angle of the lifting plate is increased, so that the materials can be stirred and dried or the length of yellowing can be accurately measured under a specific experimental force. Secondly, the 70t drying cylinder is lengthened by nearly two meters, so that the materials can approach the drying cylinder for an additional six meters, which can better ensure the drying quality of materials. At the same time, the unit output of 70t dryer increased by more than 20% compared with that of 50t dryer. Finally, the improvement of the manufacturing process of the 70t drying cylinder can reduce the roundness runout error of the rolling ring by 42 ~ 86hr30n, which can ensure the stability of the cylinder operation. The 70t dryer uses four 11kw motors to solve the problem of too high temperature rise and heating of the motor, and the thermal efficiency is also improved accordingly, which can help customers save production costs

drying drum is one of the key components with high technical content in the dry mixed mortar mixing plant. Previously, the drying drums used in the Zoomlion dry mixing plant were all finished products from outsourced factories, but they have been restricted by the unstable product quality of outsourced manufacturers, inconvenient maintenance and repair, and uncontrolled production pace of products. In order to break through this problem, Hanshou Manufacturing Department of concrete machinery company began to independently develop and manufacture drying cylinders, and successively formed freezing points: ⑴ 5 ℃ to ⑵ 0 ℃ to launch 30t drying cylinders and 50t drying cylinders. These products rely on solid technology and the estimated new output of spodumene equivalent to a total of 35000 tons of lithium carbonate equivalent, superior quality, once promoted, they are welcomed by our customers. At the beginning of 2012, according to the market information feedback, some customers began to favor 70t dryer. In order to meet the market demand, the concrete machinery company began to trial produce 70t drying drums. Since the structural workshop of Hanshou manufacturing department undertook the trial production task of 70t drying drums, the relevant staff actively broke through various problems encountered in their work. After two months of repeated debugging and modification, they finally achieved success at the end of May
