Wirtgen推出280 SM(i)“全能型”露天采矿设备

Wirtgen公司 表示，该公司研发出了一种高效的、面向生产一线的技术解决方案，该方案中的拳头产品是新款 280 SM(i)型露天采矿设备 ，这款设备可用于矿产资源的开采作业，其中采用了一些创新技术，这些技术的应用能够提高机器设备的利用率和最大生产率。

Wirtgen公司声称， 280 SM(i)型露天采矿设备是一种高性能的露天采矿设备，根据设计，这款设备可在矿产资源开采作业领域大展拳脚，包括直接装载作业、侧面卸载作业或采掘作业，从而实现性能稳定且选择性的开采生产模式。 在一次生产作业中，原矿石能够以贫化率最低的方式进行开采和破碎作业，无需进行钻孔和爆破作业，因此也最大限度地减少了对环境的影响。

这款280 SM(i)型露天采矿设备配备了履带式动力系统，该系统具有4个可转向的以及可调节高度的驱动装置。Wirtge公司表示，这款设备具有高度机动性，当采掘作业结束时可以采取快速的转向动作。这款设备采用了 LEVEL PRO ACTIVE自动水平系统 ，从而将指定的采掘深度保持在一致的高精度水平上，并且无需其他的辅助性装备。

Wirtgen公司介绍道， 280 SM(i)型露天采矿设备是一种“全能型”设备，适用于所有的岩石硬度和生产作业环境 。该公司进一步表示，2750毫米规格的采掘滚筒设备的采掘深度达到了6.5米，并且具有很高的精确度，可以应用于每个特定的作业场景，并且其采掘作业的各项性能也是十分出色的，同时还实现了最小的采掘镐磨损度。

这款设备的工具夹持系统具有较高的耐磨性，从而提供了最佳的采掘镐的使用率，并且将设备的停机时间也降到了最低限度。

The Wirtgen 280 SM(i) is a high-performance surface miner for reliable, selective extraction of primary resources by direct loading, sidecasting or cut-to-ground, Wirtgen says

虽然软岩型采掘滚筒装置是专门为软岩型矿石设计的（具有较高的矿石开采率），但是硬岩型采掘滚筒装置在硬岩型采矿作业中也具有最大的耐损耗性能和更长的服务年限。

Wirtgen公司表示，在露天矿的开采作业中，最为重要的考虑因素始终是最大限度地提高采矿生产率、开采矿石具有最低的贫化率以及对人类社会和环境的影响最低。除了设备的性能外，这款采矿设备的生产率主要取决于持续的运营准备工作和保持机器设备最佳的运行状态。只有稳定可靠且易于维护的机器设备才能确保较高的设备利用率。

这款采矿设备 采用了一种创新性驾驶室 ，这有助于操作人员充分发挥机器设备的潜能，并且最大限度地提高生产率。因此，280 SM(i)型120吨级露天采矿设备是矿山采矿生产过程的首选工具，因为它能够实现极佳的成本效益和经济效益。

The 280 SM(i) surface miner’s air-conditioned and sound-proofed operator’s cabin is swivel-mounted on the front chassis column and provides a productive working environment with a low risk of fatigue, the company says

这款采矿设备还配备了一个 后部卸料传送设备 ，这款传送设备具有较高的生产率、可调节高度（通过液压系统）、可移动式的配重系统，此外，这个传送设备能够实现向左或向右的90°旋转操作，并且其有效载荷也高达100吨。此外，在不改变发动机转速的情况下，操作人员可以持续地调整传送皮带的速度，这样就大大降低了皮带的磨损，一般来说，传送皮带的磨损情况取决于矿石/废石的量和开采材料的设备规格。

Wirtgen公司介绍道，这款新型露天采矿设备 配备了一个全新标准的正压舱（带有防粉尘空调），具有新鲜空气的过滤功能，从而有效地防止了粉尘进入操作人员的工作空间中 。这款采矿设备的一个全方位玻璃罩的驾驶室能够和设备本体进行分离，这个驾驶室被安装在左前方的底盘立柱上，可以进行向左或向右的90°旋转操作。驾驶室中最多可以安装6个摄像头，从而为驾驶员提供更开阔的全方位视野。该公司表示，这款采矿设备具有各种自动化功能，也有助于提高操作人员的舒适度，减少疲劳工作的事故风险，帮助操作人员提高生产效率，并且也使整个采矿作业过程变得更为高效。

Wirtgen公司总结道，280 SM(i)型露天采矿设备的成功应用表明保护环境和实现经济效益最大化可以做到实际上的“两手都要硬”，并且两个方面也是紧密相关的。该公司能够做到这一点，是因为这款新设备具有较低的燃油消耗率（减少了碳排放）、高效的水资源管理系统、以及有效的防粉尘污染设计方案。

Wirtgen premieres new ‘all-rounder’ surface miner for open-pit operations

With the new 280 SM(i) surface miner, Wirtgen says it has developed another efficient and practice-oriented solution for the extraction of primary resources, with innovative technologies that enable high machine utilisation rates and maximum productivity.

The 280 SM(i) is a high-performance surface miner designed for the reliable and selective extraction of primary resources by direct loading, sidecasting or cut-to-ground, Wirtgen says. Raw materials are extracted and crushed in-situ in purest quality in a single operation – without drilling and blasting, and with minimal environmental impact.

The 280 SM(i) is driven by four steerable and height-adjustable crawler units. The machine is highly manoeuvrable and can be quickly turned at the end of a cut, according to the company. The LEVEL PRO ACTIVE automatic levelling system maintains the specified cutting depth with consistently high precision and without further aids.

The 280 SM(i) is an “all-rounder” for all rock hardnesses and applications, Wirtgen says. The 2,750 mm cutting drum unit, with a cutting depth of up to 650 mm, is precisely adaptable to each specific application and achieves outstanding cutting performance with minimal pick wear, it added.

Wear-resistant toolholder systems ensure optimal pick utilisation and minimal downtime.

While the soft-rock cutting drum unit is designed especially for high material flows in soft rocks, the hard-rock cutting drum unit ensures maximum durability and long life in hard-rock applications.

In the extraction of primary resources by open-pit mining, the key priority is always a combination of highest possible productivity, maximum purity of the material mined and the reduction of impact on people and the environment to a minimum, Wirtgen says.

“Aside from performance, the productivity of mining equipment depends primarily on constant operational readiness and optimum machine use,” the company says. “Only a reliable and maintenance-friendly machine assures high utilisation rates.”

The innovative operator’s cabin contributes to the operator’s ability to exploit the full potential of the machine and maximise productivity. The 280 SM(i) surface miner is, therefore, the tool of choice for cost-efficient mining processes in the 120-t class.

The high-performance, hydraulically height-adjustable, rear discharge conveyor with a movable counterweight can be slewed to the right and left by 90° and enables the loading of mining trucks with payloads of up to 100 t. What’s more, the operator can continuously vary the speed of the belt independent of the engine speed to reduce belt wear dependent on the material volume and the piece-size of the mined material.

Entirely new standards are set by the dust-sealed and air-conditioned positive-pressure cabin on the new surface miner with fresh air filtration, which effectively prevents the ingress of dust into the operator’s workplace, Wirtgen says. Mounted on the front left chassis column, the operator’s cabin with all-round glazing is decoupled from the machine body and can be rotated by 90° in both directions. Up to six cameras can also be installed to provide even better all-round vision. Various automatic functions also contribute to the operator’s comfort, reduce the risk of fatigue, assist the operator in the achievement of high productivity rates and make the overall process more efficient, the company says.

“These days, the reduction of carbon emissions, noise, dust and vibration while maintaining consistently high extraction rates and productivity is more important than ever before,” the company says. “With the new surface miner, Wirtgen offers innovative technologies that minimise impact on the environment and conserve valuable natural resources.”

Thanks to the reduction of carbon emissions by low specific fuel consumption, an efficient water management system and effective solutions for the minimisation of dust pollution, the 280 SM(i) shows that ecological and economic considerations are actually compatible and closely interconnected, Wirtgen concluded.
