New EVO2 Generation Guarantees Higher Operational Reliability

SOURCE: Kleemann | June 30, 2022

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 plants are equipped with mechanically and software-supported overload systems.

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.

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 thus 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”).

Intelligent “Ringbounce Detection” with the cone crusher MOBICONE MCO 90(i) EVO2 reacts to an excessively large share of fines in the feed material and prevents clogging of the crusher.

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

New Kleemann Plant Marks Commitment to Industry
In early 2010 Kleemann GmbH completed its new headquarters and state-of-the-art manufacturing plant near Göppingen, just east of Stuttgart in south-central Germany.

The new plant marks Kleemann’s commitment to the minerals processing industry and incorporates the highest production technologies for the manufacture of aggregates and minerals processing equipment.

This new “greenfield” manufacturing plant is making Kleemann mineral processing equipment more available, and will speed product delivery in North America in coming months. “With 350,000 sq. ft. of production area and 40,000 sq ft of administration area, Kleemann will excite the market with new models and features for 2010,” said Evan Clarke, vice president.

For over 150 years Kleemann has led the minerals processing industry with design ingenuity, producing crushing and screening equipment for many leading markets. Since being acquired by the Wirtgen Group in 2006, the company has experienced dramatic growth which has led to reinvestment by the group to help streamline production and allow for greater volume for its new expanding markets.

“As Kleemann gathers momentum within the United States and Canadian markets, and new dealers take on the product line, many customers are seeing the ‘Kleemann Advantage’,” Clarke said. “We bring to the market a wide range of track mobile crushers and screens with many unique features.”



The new plant utilizes the most modern German high-tech manufacturing processes, including short internal product assembly lines. On the new 1.34 million sq. ft., site, the new manufacturing facility covers an area of 376,736 sq. ft., complemented with a 43,055 sq. ft. administration building. The oversized interior capacity of the new main production facility accommodates the enormous dimensions of Kleemann’s largest crushing and screening machines.

In the plant’s central warehouse contains two storage zones in which some 10,000 items are stocked. “On average, 200 items with a total weight of 8.8 tons are handled here each day,” said Kleemann central warehouse manager Martin Zemmel. “We really benefited from the know-how of the other Wirtgen Group companies when building our new facility.”

Kleemann’s new painting facility for large parts is one of the largest such facilities in Germany, with a tremendous load-bearing capacity of 33 short tons, and around 21,500 sq. ft. of floor space. Kleemann’s switch-over from wet spray painting to powder-coating not only marks a major step towards boosting surface quality, but also has far less of an environmental impact, with the system far exceeding the requirements of the EU environmental guidelines.




Kleemann’s Roots Run Deep


Kleemann is a newcomer to the North American aggregate processing market, but its roots lie deep. Established in Germany in 1857, Kleemann was acquired by Wirtgen Group in 2006. Today, a growing network of equipment distributors and dealers is enabling Kleemann Inc. USA to boost its domestic profile and serve customers in North America.
Today Kleemann manufactures and markets a broad range of durable, productive mobile and stationary processing equipment and technology for crushed stone, demolition waste and mixed construction waste.

Kleemann’s product brand names are:
• The MOBICAT mobile primary jaw on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100-1,000 tph capacity
• The MOBIREX mobile primary impactor on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100 to 1,000 tph capacity
• The MOBIFOX mobile secondary crushing machines with feeding unit, impact crusher and a screen producing up to 3 grain sizes
• The MOBICONE mobile secondary crushing machines with feeding unit, cone crusher and a screen to produce up to 3 grain sizes, and
• The MOBISCREEN mobile screening machines, producing up to 4 grain sizes with fixed or swiveling discharge belts, with a screening surface dependent on ultimate use.
