With the new 280 SM(i) Launch of surface mining machine，The Wirtgen Group offers another efficient and practical solution for primary mineral extraction。This innovative process has greatly improved machine utilization and production.，Can not only achieve 100% The rate of exploitation，A single machine can also realize the environmental protection of primary mineral materials.、Efficient、Safe mining。

Complete the cutting of primary mineral aggregate at one time、Broken、Loading and other whole processes

280 SM(i) It is a high-performance surface mining machine.，The stripped primary mineral aggregate can be directly loaded onto a transport vehicle through a discharge belt，The material stacking belt can also be thrown through the discharge belt side or the discharge belt is not installed.，Treated by means of a post-discharge stackyard。Drilling and blasting are not required in the process.，The machine is capable of stripping and crushing the primary mineral in situ in an environmentally friendly manner，So that that quality of the ore is ensure。

280 SM(i) It is driven by a four-track track with adjustable height and steering function.，When the cutting operation is carried out from the previous one to the next one，The machine can be easily controlled.，Fast and flexible steering。And LEVEL PRO ACTIVE The automatic leveling system can continuously and accurately construct according to the set cutting depth.，No further assistance required。

Site application case of lossless mining of mineral materials

Efficient cutting technology

280 SM(i) Suitable for all hard rock mining and various construction applications，It's real“Versatile”。2750 mm Wide cutting rotor，Cutting depth up to 650 mm，Can precisely meet the needs of specific applications，Achieve excellent cutting performance while ensuring little wear of the tool bit。The high wear-resistant tool holder system greatly improves the utilization rate of the tool bit.，And effectively reduce downtime。

In addition，Soft-rock type cutting rotors ensure efficient material flow when mining soft rock，Hard-rock type cutting rotors for hard rock mining ensure durability and longer service life。

Higher utilization leads to ideal productivity

When mining the target mineral using the open pit mining process，The priority is always to ensure the purity of the mineral aggregate as far as possible.，While minimizing the impact on people and the natural environment，Maximize production。In addition to performance，The productivity of mining equipment mainly depends on the utilization rate of the machine under long-term working conditions.，And is easy to maintain、Stability and reliability is the key to higher utilization of this new model.。At the same time，The newly designed cab helps the operator to make the most of the machine's potential，And maximize the productivity of the machine。So，Wittgen 280 SM(i) As a 120-ton open-pit mining machine, it is to achieve low cost.、Ideal for efficient mining。

Strong belt discharge ensures ideal material flow

280 SM(i) The surface mining machine is equipped with a rear discharge belt with super conveying capacity.，The height can be adjusted hydraulically and the counterweight can be turned 90 degrees to the left and right° Swing，So that that continuous feed to the ore cards of more than 100 ton is realized。In addition，The operator can be independent of the engine speed，Continuously changing the speed of the discharge belt according to the volume and particle size of the mined ore material，O as to reduce the abrasion of the mineral aggregate on the discharge belt.。

Driving comfort

280 SM(i) The cab is equipped with a new supercharged dust-proof mechanism and an air filtration system.，It can continuously supply fresh air to the cab.，Effectively prevent dust from entering the working space，Ensure operator's health and comfort。Panoramic glass cab located on the left-hand side of the machine above the track outrigger，Can be rotated 90 degrees left and right° Lay out the fuselage，To get the best working perspective；The six cameras provide the operator with a full range of vision.。

In addition，Multiple automated controls help to significantly reduce operator fatigue，Improve driving comfort，So that the construction is more efficient.！

Save resources、Protect the environment

It is important to consistently achieve high rates of extraction and production during the mining process.，And reduce carbon emissions.、Noise、Dust and vibration，Nowadays, more and more attention has been paid to it.。The new model 280 from the Wirtgen Group SM(i) Surface mining machine，Reducing the impact of the open-pit mining process on the natural environment，Let precious resources be better protected。At the same time，This machine fully meets the requirements of low fuel consumption、The need for low emissions，The water management system with automatic function can effectively reduce dust pollution.，Significantly reduce water waste and equipment continuous working hours，To achieve a win-win situation of economic and ecological protection。
