Flexible screening

Always the perfect setting – the HAZEMAG VARIOwobbler

Dülmen, February 2010 -HAZEMAG & EPR GmbH in Dülmen introduces the HAZEMAG VARIOwobbler, which represents a new generation of wobbler feeders for pre-screening operations in crushing plants. An outstanding feature of this wobbler is the facility for infinitely varying the gap between the individual shafts by means of an effective hydro-mechanical control system, in order to determine the screened product granulometry at the touch of a button and without the use of any tools. This system allows for quick and flexible reaction to changing requirements and ensures that the feeder is always adjusted to the correct setting. (see Fig. 1 below).

Such a system is of particular interest under the following circumstances:

When weather conditions fluctuate, there can be changes in the H20 content, and consequently in the screening behaviour of the material to be processed. The gap setting adjustment facility provides the optimum means to compensate for any such variations during the screening operation.

In quarry operations, the characteristics and properties of the recovered material – for instance, the proportion of actual suitable material, and thus the screening behaviour - can vary. In such cases, the optimum setting can be selected similarly at the touch of a button.

If market or customer demands and requirements change, i.e. should a coarser product be desired, the gap setting is simply widened, and likewise, if a finer product is called for, the gap reduced appropriately.

In a conventional vibrating screen, to undertake such changes involves considerable time and effort in changing the actual screen grates. The new VARIOwobbler screens can replace a conventional screen in a crushing plant without any problems; they can be designed as single- or multi-stage machines, according to whether or not existing machine height differences need to be overcome. Thanks to the various stages, the material flow is agitated several times, facilitating the downward flow of the fine material from the upper layers of the material bed and separating these fines from the coarse material. Additionally, the fines - which often contain a high percentage of the material's moisture content – are removed prior to entry into the crusher, avoiding the potential danger of clogging and caking in the actual crusher. The wobbler itself is not affected by sticky material. All the shafts of the VARIOwobbler are individually driven.

The use of these roller screens leads to increased operational safety and to a reduction in energy and operating costs:

Thanks to the horizontal material flow on the roller screen, the downstream crusher is fed evenly and uniformly in a controlled manner. By separating the fines, the load on the crusher is reduced, resulting in less wear and reduced power requirements, and even possibly to the introduction of a reduced crusher size.

The HAZEMAG VARIOwobbler has been designed for the following applications:

Types of material:Limestone, Marl, Clay, Coal, Natural rock, Minerals with sticky inclusions, etc.

Feed size:0 – 1500 mm

Separation:15 – 150 mm

Capacity:up to 2,500 t/h

Width:up to approx. 3.5 m

Clay crushed by a Horizontal Roll Crusher

With the feed material being Clay -Sticky, Wet and Hard-with a feed size of 500mm ( 19 5/8 inch) to be crushed to a final size of 0-60mm ( 2 3/8” minus) was the challenge, These are the operational conditions the HAZEMAG horizontal Roll Crusher FB 0708 is facing a prepared to conquer..

At the end of 2008 Peißener Tonprodukte GmbH & Co. KG was in the process of commissioning its new materials preparation plant for clay.

The clay is used as an additive in the cement making process and has to have a specific size. During the crushing process, extra attention has to be paid to the stickiness and moisture content of the feed material. In addition, the feed material ( 500mm or 16 5/8” x 0) has to be guaranteed to be reduced to 0-60 mm (0 x 2 3/8”) taking into consideration that the material hardness is 160 MPa (23,200 PSI) and impurities of limestone can reach 200 MPa ( 29,000 PSI).

The customer was finally convinced of solving this crushing challenge because of the many advantages /solutions the HAZEMAG Crusher was offering. The Light and Compact Design combined with easy installation and inexpensive setup and material feeding were obvious. Today the HAZEMAG SOLUTION is one of the main plant components – assuring the company a successful operation.

The Horizontal Roll Crusher type FB 0708 consists of two main subassemblies:

•Crushing Roll

•Chain Conveyor.

The arrangement of the crushing roll above the chain conveyor makes the chain conveyer both the

feeding conveyor and the discharging conveyor –All In One! Due to Single direction material flow, oversized material can be crushed and blockages or non crushable feed occurs (ie. metallic tramp metal), the blockage can be cleared by simply reversing the feed direction. At the same time horizontal crushing accommodates feeding at grade or with only small ramps but usually WITHOUT feeding hoppers. Even when hoppers are desired, as was the wish of Peißener Ton, feed with trucks can be easily accomplished without concrete pads or expensive ramps.

The light and compact design makes it easy to transport, set-up and commission these crushers on site. No special construction work such as concrete foundations is necessary. Only two 8 hour shifts were needed to setup this plant, ready to run!

The plant was handed over to the pleased customer after fulfilling a performance test of 200 metric tons per hour plus reaching all other parameters such as final product size etc.

At BAUMA 2010, HAZEMAG is displaying one of the bigger brothers the FB 1111. This crushers’ technology can be used for Gypsum, Potash, Coal and many softer minerals at feed sizes of up to 1500mm 5 Feet) with throughput rates of 1000 tph. Make it a point to stop and see Hazemag at BAUMA 2010 in front of Hall B2 219/230. Also, don’t forget - if you have to crush harder stone, our impact roll crushers can be used for the hard stone, also. These same machines are crushing granite and gneiss in the Switzerland along with the hard rock tunnelling application which is commonly know as NEAT (New Alp Transit / St. Gotthard).

It just won't stop – the HAZEMAG Sand Impactor AP-KV for mechanical sand and chippings

This classic machine has been making regular appearances at the BAUMA Trade Fair in Munich for quite a long time. This year, however, the sand impactor is being presented as a completely overhauled and updated version: four generously-sized doors provide full access to the internals, to optimise servicing and maintenance work. Not only has the external appearance changed – the new technology is also impressive. The blow bars are now inserted laterally to permit quick and easy turning & replacement, and the impact aprons have a push-button hydraulic adjustment system; another plus towards ease of handling. The housing is lined with manageable, easy-to-change wear plates. Approximately 97% of the wear liners are interchangeable, which means that spares holdings can be reduced correspondingly. (Fig. 4).

This "marathon runner" was designed with a reversible rotor to be fitted with two or four blow bars, depending on the specific application. Thanks to its symmetrical design, it is possible for the rotor to be run in a clockwise or anti-clockwise direction, so that the blow bar striking edges are utilised to the full. The sand impactor can be deployed both as a secondary or a tertiary crusher, to generate a product ranging from coarse to fine. Based on a feed size of up to 100 mm, gravel, granite, basalt and even slag can be processed to generate mechanical sand or fine and coarse chippings with minimum filler content. The chippings thereby produced possess an excellent cubicity.

The plant is completed by a vibro-feeder, which provides for optimum feed material distribution over the whole width of the rotor and consequently for the even wear of the blow bars. This in turn ensures that the wear rate of the blow bars is optimum and the product quality high and uniform. This latest version of sand impactor has a capacity of 50 – 120 t/h and is manufactured in HAZEMAG's own workshops, taking advantage of the state of the art fabricating facilities available there.

HAZEMAG Dinting Loader EL 160: VERSATILE TALENT

HAZEMAG dinting loaders of the EL 160 series are very successful in the coal mining industry all over the world in the field of maintenance and repair of underground galleries. The compact design of the dinting loader EL 160 permits its application in narrow spaces. For crushing rock fragments five hydraulically driven impact chisels are integrated in the bottom of the box-type bucket.

As an alternative to this bucket the machine may be fitted with a hydraulic rammer for especially difficult operating conditions as e.g. for loosening parts of rock with a high compressive strength or for crushing large-scale rock plates.

(Fig. 5).

At the BAUMA Fair in Munich HAZEMAG is going to present the newly-developed version of the EL 160 LS with a gun-mount for blast hole- and anchor bore hole drillings. By using modern construction- and production technology as well as high-quality materials this new gun mount achieves a low dead weight and, at the same time, a very high stability. This allows high drilling speeds at a high precision of the boring. In case of the exhibit the drilling tasks are carried out with a hydraulic drifter in a rotary-percussive drilling method up to a diameter of 52 mm and a boring depth of 2.4 m in hard rock. Due to the quick and exact positioning of the drill boom towards the starting point of the boring very good drilling results are achieved. A hydraulic quick changing device on the drill boom permits the conversion to a side tipping bucket for loading the previously blasted rock on the available conveying system within a short time. (Abb. 6).

The use of modern hydraulic components coupled with a powerful cooling plant permits a reliable and fail-safe operation in areas with high ambient temperatures. In accordance with the respective country-specific legal requirements the machine is equipped with electro-technical components which allow the application in mines with methane gas.
