Keestrack presents innovations on Bauma China 2018
Growing with the market(s)
In 2007 Keestrack, the Belgium-based specialist for mobile mineral processing plants, set up its own subsidiary in China – Keestrack Construction Equipment Ltd. Today, “Keestrack China” covers the Chinese and South-Asian markets with a modern production facility located in Chuzhou and a fast-growing aftersales organisation. At BAUMA China 2018 (Shanghai – November, 27 to 30 2018), the company will present a comprehensive extract of Keestrack’s large tracked mobile machine programme, covering all relevant screening and crushing technologies for quarrying, mining, recycling and aggregates industry applications (Stand A18).
Opened in 2012, the current 14.000m²-facility of Keestrack China in Chuzhou – 350 km north-west of Shanghai – accommodates plant production and assembly, a large parts centre and a training centre for customers. The production programme includes models of Keestrack’s classifiers and impactors and will be soon extended to the company’s scalper range. Supplying the Chinese and South-Asian market regions, Chuzhou is fully integrated in Keestrack’s worldwide R&D and manufacturing network. Continuous investment in all group’s production facilities – like anti-corrosive zinc-phosphate Nano powder painting technology – ensure the highest quality standards on a global level.
Vision in hybrid and plug-in technology
Keestrack provides a comprehensive product range of highly mobile tracked crushing and screening solutions with transport weights from 14 to 70 tonnes, with today 24 models in seven product lines. Leading in innovation, Keestrack promotes diesel-electric and full-electric drive options for all applications. Today 80% of the company’s product range is optionally available as diesel-electric hybrids and 75% as plug-in hybrid. According to Keestrack, these alternative drives result in energy cost savings up to 80% and noise emissions to drop by 30% at plug-in mode with the whole plant supplied through mains. In 2012, the Chinese factory produced the first hybrid, diesel/electric classifier, the Keestrack C6e, especially for the Chinese market.
With a total of four exhibits at their Bauma China stand (A18), Keestrack will show the latest technologies in their mobile crushing and screening equipment. Local and international sales and application experts will provide extensive information for all relevant sectors. The planned display presents the following machines:
• Jaw crusher Keestrack B4
The B4 jaw crusher ensures less wear and better crushing capacities due to its double-deck vibrating pre- screen (2300x1000 mm). The proven jaw crusher 1100x700 mm (max. feed size 600 mm) reaches an hourly output up to 400 tonnes and provides a hydraulic automatic gap adjustment to safely prevent clogging and automatically adjust the jaw plates to compensate wear. For optimized maintenance, the B4 has a hydraulic sliding frame for service access under the feeder and scalping unit. Optionally, the plant can be equipped with a single-deck post screening unit.
The track-mounted jaw crusher is also available as hybrid plug-in B4e version with drop off power-supply module. The hybrid version of the successful 50-tonnes model B4 enables plug-in operations from the mains and is an economical alternative for semi-stationary deployment at recycling companies, large construction sites or quarries.
• Cone crusher Keestrack H4e
The fully hybrid cone crusher H4e highlights Keestrack’s philosophy of combining the best flexible mobility with high productivity. Unique on the market with its optional 3-deck hanging screen, the fully equipped plant weighs only 46 tonnes (without options: 35 t), offering easy one-piece road transport and fast relocation on site.
For flexible autonomous operation, the Keestrack H4e is equipped with an on-board diesel engine. The engine drives an alternator, providing power to the electric motor of the crusher drive and to the separate E-motor/pump unit for all hydraulic drives on the plant (tracks/fans/screens/hydraulic cylinders). Without starting the diesel, this setup enables the plant to operate fully “plug-in” from mains or external gen set, resulting in energy cost savings up to 70% compared to conventional diesel-hydraulic plants. The H4e has a detachable drop-off unit and can be placed remotely during operation, this reduces dust and vibration on the drive unit and facilitates easy maintenance.
The fully automated unit produces up to 250 tph at maximum feed sizes of 185 mm. The wide variety of concaves allows a high flexibility in secondary or tertiary production of highly defined end fractions. To optimize production the plant can be optionally equipped with a pre-screen with fines chute and with a highly efficient three-deck secondary screen module with recycling conveyor for closed-circuit processing. The large measurements of the hanging screen (effective area: 3 x 5.4 m²) and large stockpiling capacities of the conveyors prevent bottle-necks in producing up to four highly defined quality end products.
• Impact crusher Keestrack R6
The fully equipped tracked mobile impact crusher R6 with independent dual-deck pre-screen (3100x1250 mm), double-deck post-screen module (4500 x 1500 mm) and recirculation of the oversized fraction, weighs just over 61 tonnes. With its efficient 1300-series crusher (inlet size: 1300 x 970 mm, rotor weight: 6,100 kg) it has a capacity up to 500 tonnes/hour. The track mobile impactor can be transported as one-piece without disassembling the after-screen module. This improves mobility, shortens downtime and guarantees profitability. The R6 impactor provides a very high reduction ratio with excellent product shape. Just like all other Keestrack diesel/hydraulic driven equipment the R6 is using a load sensing hydraulic system which reduces the fuel usage by 25%, compared to traditional diesel/hydraulic equipment.
With an extensive option list the crusher can be configured to specific needs and applications. The Keestrack R6 is also available in a hybrid R6e version with full-electric rotor drive or direct “rotor-by-diesel” drive configuration.
• Scalper Keestrack K6
The K6 scalper is the most mature scalper on the market, introduced in 1996 as the first direct feed scalper. An innovation by Keestrack turned into today’s industries standard. With its standard heavy-duty plate apron feeder and double deck screen of 4500x1800 mm it has a capacity up to 600 tonnes/hour. The low emission engine and load sensing hydraulic system ensure the lowest fuel consumption in the industry. The Keestrack K6 is also available as energy saving hybrid plug-in electric drive.
