Avoid downtimes with effective overload systems

In rock and stone processing, during the crushing process various short-term or prolonged overload situations can arise. The overload systems of the MC 110 EVO2 and MCO 90 EVO2 pursue an important goal: increase in the operational readiness of the plant in a sustainable manner by guaranteeing a crushing process that is as continuous as possible. Both crushing machines are equipped with mechanically and software-supported overload systems.

 Overload system on the jaw crusher MOBICAT MC 110(i) EVO2

With its multi-stage overload system, the jaw crusher MOBICAT MC 110(i) EVO2 provides more safety with uncrushable material. If, for example, metal enters the crushing process, the crushing gap (CSS) opens automatically in up to two seconds over the complete gap range. The crusher itself does not have to be stopped during the temporary overload situation, which means that the crushing chamber is empty and manual clearing of the crusher is not necessary which saves work and time. When the overload situation is corrected, the system then moves back to the original crushing gap and the crushing process is continued. The pressure plate installed as a predetermined breaking point is preserved. The consequences are reduced downtimes and increased crushing capacity.

Overload systems on the cone crusher MOBICONE MCO 90(i) EVO2

The cone crusher MOBICONE MCO 90(i) EVO2 has two different systems installed. The overload system “Tramp Release” protects the crusher against uncrushable material such as wood or metal. The bowl including the bowl liner lifts automatically to allow uncrushable material to fall through. The “Ringbounce Detection”, on the other hand, reacts to an excessively high share of fines in the feed material and prevents “briquetting” – which means the clogging of the crusher or sticking together of the material. Here, the hydraulic pressure of the crusher is monitored continuously. The system reacts as required and therefore prevents latent overloads. Depending on the machine application, the “Ringbounce Detection” can be oriented via the control system to output (“Mixture Mode”) or product quality (“Precise Mode”).

By preventing machine damage and thus production downtimes, the overload systems from Kleemann therefore guarantee increased operational reliability for the users.

Environmentally sound combined with an economic solution – The jaw crusher MOBICAT MC 110(i) EVO2 and the cone crusher MOBICONE MCO 90(i) EVO2, with their efficient crusher direct drive, have a holistic drive concept that forms the basis for high cost-effectiveness.

Crusher direct drive with electric auxiliary drives – fuel-efficient and quiet

Both machines of the new EVO2 generation are equipped with a patented power train. The crusher is driven directly, enabling high fuel-efficiency, via a reliable fluid coupling. Conveying components, such as the vibrating feeder, the double-deck prescreen or the discharge conveyors, are all-electric. A robust and easily accessible gearbox guarantees efficient power transmission. It not only operates with a high level of efficiency but also has ideal protection against dust. Downtimes can be avoided to a large extent. The power and load-dependent fan drive also ensures low-noise and economical operation. Operation in ECO mode can additionally reduce fuel consumption as well as wear in idle phases. The plants can be optionally equipped with a heat package (-15 to + 50 °C) or cold package (-25 to +40 °C). The cold package has an autonomous auxiliary heater with a convenient timer function.

Environmentally sound operation – less noise and dust

In the new drive concept, the speed of the cooler fan and therefore also the cooling capacity is controlled automatically, which considerably reduces the noise level. Apart from less dust penetration thanks to a lower volume of moved cooler air, work near to the machine is a lot more agreeable for the operator.

For the jaw crusher MOBICAT MC 110(i) EVO2, which is frequently used in urban environments, an optional noise protection package is also available. The considerably reduced noise level would even permit work without special ear protection – depending on the material to be processed, further environmental conditions and local regulations.

To reduce dust, the machines are equipped in the standard series, among other things, at the crusher inlet and crusher discharge conveyor with water nozzles and the corresponding technical infrastructure. As a result, an optionally available water pump or an external water source, if available, can be used. Optional belt covers also contribute to an improvement of the air quality during crushing.

These measures benefit the machine operator, the further peripheral devices on the job site, local residents and the environment.

The new MOBISCREEN MSS 802(i) EVO offers users a mobile, efficient screening plant that was designed to meet changing challenges in different application areas. With its well-thought-out plant design and flexible conversion options, Kleemann demonstrates how a high material flow can be guaranteed in natural stone and recycling applications.

Screening made easy

With the development of the MOBISCREEN MSS 802(i) EVO, a new generation of screening plants and successor of the MS 15 Z, Kleemann consciously places the focus on the user perspective. The technology behind the screening process must be easy and safe to use for all users. The new plant impresses not only with technological highlights in the process sequence, but also through its ergonomic design, optimised operation and the user-friendly maintenance concept.

Improved mobility and flexibility in application

With its proportionally controlled running gear, the plant can be quickly relocated either by a low-loader to the job site or within the building site. Apart from other improvements of the new MSS 802(i) EVO, folding of the side discharge conveyors without the need for disassembly clearly reduces set-up times. Increased application variability is provided by a hopper rear wall that can be folded to three heights, which permits feeding of crushing plants with a lower discharge height. The large offer of screen surfaces and simple adjustment of the screen parameters, which make rapid adaptation of the MSS 802(i) EVO to a very wide range of feed materials possible, reduce set-up times and thus personnel requirements and costs. The screen casing angle with a wide adjustment range from 15.4 – 20° makes optimisation of the screening capacity possible. Special highlight: the simple and fast conversion from 3- to 2-way grit. The MSS 802(i) EVO can therefore be used to produce and discharge two or three final grain sizes and the conversion is fast and simple.

Operability and ergonomics for more comfort and safety

An intuitive plant control with automatic start reduces the risk of operating errors and saves learning times. All relevant functions can be operated from a safe distance, which offers high work safety. Further user-friendly aspects include very good access options and intelligent cleaning solutions, which minimise downtimes caused by maintenance. With all of these solutions, Kleemann placed the focus on the typical workday of users. This also applies to the standard series LED lighting, the optionally available extended premium lighting of work areas or the generously proportioned work platforms.

Efficient and precise process sequences for optimum material flow

An optimised material flow is a central aspect of all screening plants. Only if all components are tuned to one another can high productivity with minimised operating costs be achieved. With its new mobile screen for coarse elements, Kleemann demonstrates what screening plants of the latest generation can achieve. This includes a wide crusher discharge conveyor on which, like all of the other conveyors, the speed can be steplessly adjusted, as well as a large material transfer system to the screen deck for optimum utilisation of the screening surfaces. High discharge heights and thus higher stockpiles thanks to the optionally available extended crusher discharge conveyor and telescopic side discharge conveyors guarantee ideal processes on the building site.

It goes without saying that the new MOBISCREEN MSS 802(i) EVO can be operated through line coupling with all EVO and PRO crushing plants integrated in the process and safety system. Special application flexibility is provided by the stockpile probe required for the process coupling, which can be placed on any discharge conveyor of the plant.
