is equipped with a newly de- veloped dosing device which allows the use of an additional blasting material in the dry ice stream. Tanks to this system, customers receive the best combination of gentle clean- ing with dry ice pellets and the additional abrasive effect of a carefully selected additive. Tis turns the ASCOJET Combi blaster 1708 into the


perfect, complementary symbiosis: Only the additive addition makes dry ice blasting abrasive and thus increases the effective- ness of this technology for certain applications to achieve a highly efficient result. In return, dry ice blasting supports the erosive effect of the abrasive blasting material and provides optimum protection of material due to the dry ice´s cooling effect. Tereby, it protects the surface from overheating which can be the case with pure abrasive blasting processes. Limited use of blasting material ensures that low dust is formed and for this reason only a minimal secondary pollution is generated. Te well-tried advantages of ASCOJET dry ice blasting units, such as an easy operation and a self-explanatory operator panel, have been retained in the new ASCOJET Combi blaster 1708. Due to a higher cleaning performance, the device can be operated with less compressed air which leads to a considerable reduction of noise emission—an important criteria for each customer. In addition, a stainless steel cover prevents corro- sion during use and the low need of material and air consumption guarantees an economical operation of the combined dry ice blasting unit. ASCOJET Combi blaster 1708 can be used


where normal dry ice blasters are pushed to their limits because of their non-abrasive effect. Metalcasting facilities can clean and/or oc- casionally roughen their ingot molds and core- boxes efficiently and directly on the machine. Te forms are hardly cooled, production can be resumed immediately after the cleaning process and expensive downtimes can be avoided. Te ASCOJET Combi blaster 1708 is


flexible, as well. Users can choose at any time between pure dry ice blasting or combination blasting with dry ice pellets and additive. Visit ASCP at GIFA, June 16-20 in Düsseldorf, Germany, Hall 15 / E08. 


使用附加的研磨材料。 正是有了这样的系统, 客户可以同时获得干冰 粒温和的清理效果和仔 细挑选的磨料带来的附 加的研磨效果。 这使ASCOJET Com-


bi blaster 1708产生了完美、互补的协同效应:仅仅添 加磨料使干冰喷射具有研磨性,从而提高该项技术在某 些应用中的有效性,取得高效。同时,干冰喷射支持磨 料的研磨作用,并且干冰的冷却效果产生了最佳的材料 保护效果。因此,该系统可防止表面过热,也就是纯粹 喷砂处理时出现的情况。磨料的有限使用仅产生少量的 灰尘,因此,只会产生轻微的二次污染。经多次试验证 明的ASCOJET干冰喷砂处理单元的优点,例如易于操作 和清晰易懂的操作台,已经保留在新研发的ASCOJET Combi blaster 1708中。由于其清理效果更好,设备的 操作只需要少量的压缩空气,将大幅降低噪音的产生, 这是对每一位客户都非常重要的指标。此外,不锈钢盖 防止使用过程中的腐蚀,而且,材料和空气需求量减少 使结合磨料的干冰喷清理单元的运行更加经济。 当不含有磨料的普通干冰喷 射设备能力不足时,就要用到 ASCOJET Combi blaster 1708。 铸造企业能够在设备上高效且直 接地对钢锭模和芯盒进行清理, 有时也可以使它们变粗糙。模型 很难冷却,因此生产可以在清理 工序后立即恢复,并且可以避免 昂贵的停机损耗。 ASCOJET Combi blaster 1708 也具有灵活性。用户可以随时在纯 干冰喷射系统或复合添加剂的干冰 粒喷射系统之间进行选择。 ASCP将参加6月16-20日在杜 塞尔多夫举办的GIFA展,展位号 Hall 15 / E08,欢迎参观。 
