Kleemann MC110Z EVO units in action

New generation of mobile jaw crushers in use by quarrying and recycling customers across Europe

AT the Bauma exhibition in Munich earlier this year, Kleemann presented for the first time their all-new mobile jaw crusher, the Mobicat MC110Z EVO, which has been specially designed to meet the needs of contract crushing contractors, for whom ease of transport, plant versatility and efficiency, and low operating costs are key factors.

Since the market introduction of the compact new-generation machine, several units have entered service with customers working in quarrying and recycling applications.

One of the first series production plants is in operation with Grathwohl Erdbau und Abbruch GmbH, in Grünstadt, Germany, primarily for use in the recycling of demolition material.

‘We mainly process mixed rubble and concrete, some of which is strongly reinforced. In such applications the plant simply has to complete its task reliably,’ said managing director Nadine Grathwohl.

‘Some of our applications contain substantial amounts of fine material, so effective pre-screening is particularly important to us. This is why we selected the ‘Z’ version (pictured), which is ideally equipped for this task thanks to its active double-deck pre-screen.

Meanwhile, the company Décremps, based in Amancy, France, has been operating in the field of structural and civil engineering for more than 40 years and is also active in earthwork and demolition.

The latter mainly involves the fast and efficient crushing of concrete; in most cases material with a maximum feed size of 600mm is crushed to a 0–60mm final product. Because the material often has a high iron rebar content, it is important that there is sufficient space under the crusher to prevent blockages.

The MC110 scores highly in this respect with its generous clearance and easy access if a blockage should occur. However, it is the output of the plant that has particularly impressed Décremps, who state that it is significantly higher than that of similar competitive machines, and has a considerably lower diesel consumption.

When quarrying company Glendinning, based in south-west England were searching for a new mobile jaw crusher in the 1,100mm class, the MC110 was looked at with great interest and a plant demonstration was arranged and carried out.

‘The test material was very coarse and, in parts, sticky sandstone. Directly following the jaw crushing stage it was further processed by a cone crusher for subsequent screening into different end products.

‘Because it was followed by the cone crusher, very good pre-screening was particularly important,’ explained Michael Schwarz, Kleemann sales manager Europe. ‘The double-deck pre-screen was, therefore, of great importance and Glendinning were impressed by its highly effective operating principle.’

Glendinning were also impressed by the well-thought-out material flow, the low fuel consumption and the high-quality design of the plant, all of which contributed to a very successful plant demonstration – so much so that the company purchased a plant of this type a few weeks later.
