辊压机装备技术的新发展与应用

New development and application of roller press technology

近几年辊压机装备技术出现了一些新的优化和改进措施:(1)采用复合铸造辊面和硬质合金柱钉辊面可以有效提高辊压机辊面使用寿命和设备运转率,减少辊面维护时间,节约人工成本。在研磨磨蚀性高的物料时,这两种新型辊面的优势尤为明显。(2)新结构的侧挡板装置解决了以往侧挡板与辊子端面磨损严重等问题,并且很大程度上减少了辊边漏料,从而使粉磨压力在辊宽方向上的分布更为合理,有效地减小了边料效应。(3)可翻转侧梁的开放式机架结构简单,容易制造,零件互换性好,很大程度上降低了辊压机的起吊及检修难度,减少了检修的工作量,大大缩短了检修周期。(4)采用调心滚子轴承可简化辊系轴承座结构和改善油缸受力,运行平稳,检修方便。

In recent years, following new optimization and improvements are conducted for roller press device and technology:(1) By using compound casting roller surface, or mounted with hard-alloy column nails, the service life of roller surface and the running rate of roller press can be effectively raised to reduce repair time for roller surface and to save manpower cost. The superiority of these two new types roller surface will be more obvious when high abrasive materials are ground.( 2) Side-apron device in new structure has solved the before problem of serious wear and tear between side-apron and roller end-surface, as well as greatly reduced material leakage at roller side, which makes the grinding pressure to spread more reasonable along the roller wide direction, and to effectively reduce the 'Side material effect'.(3) Open-type frame structure with turnover-able side-beam is simple in structure and easy to be manufactured with good interchangeable parts, which is greatly convenient for roller press in hoisting and maintenance to reduce repair working and time.(4) By using self-centering roller bearings, the bearing socket structure of roller system can be simplified to improve pressure bearing of oil cylinder, which will ensure smooth operation and easy for repairing.
