Our Wobblers in Detail

Roller grate systems are justified because no other technology can separate such large rock from fine material.

The design is really robust, stones of up to 1,800 mm can be fed in.

It is the only technology in which such large stones can be screened and cleaned.

This is the only way to achieve a pre-separation of difficult, sticky, cohesive bulk materials such as soils or material with caking.

This is the case with all wobbler systems available on the market and cannot be achieved to the same extent by any other technology.

For more than 20 years we have specialized in optimizing this technology. Through years of tests and observations of wobblers from other providers, we have carried out studies and put all the knowledge we gained into our product development.

We are the only manufacturer where the shafts can run continuously at very different speeds. It can be rotated forwards and backwards and overload can be detected. So we have the intelligent wobbler, which reacts optimally to every rock and cleans it optimally.

Schmidt-Posch products stand out from their competitors due to the following product advantages:

Stationary, on a skid or fully flexible track mounted.

Our wobblers are all available in these different variants

You can install our machines in an existing processing plant, you can place skid-mobile systems on a concrete box or you can use them with full flexibility track mounted directly at the changing processing location (in-field screening).

Operation with 10-12 l / h or mains power:

Low operating costs with optimum performance thanks to diesel-electric drive.

All of our systems can be operated with public mains electricity by plug-in.

When operating with the on-board power generator, an average consumption of 10-12 l / h with a throughput of

600 t/h can be expected. (corresponds to 0.02 l/t)

Wobblers:

Technique of rotating movement of shafts for

Rock screening and cleaning

The core of our wobblers consists of massive, high-strength shafts that are fitted with individual Hardox discs.

The shape of the trimmings has also been optimized so that it has the best effect for the operator.

The polygons on which the material "runs" set the rock in constant motion.

The shafts rotate synchronously or with two- or three-, four- and five-stage wobblers with different speeds and different reversing intervals (pilgrim step forwards and backwards).

This means that we can precisely determine the length of time the rock remains at each individual stage and directly influence the degree of cleaning and throughput.

This is a very important unique selling point of our systems.

With our wobbler machines, the material is intensively pre-screened and the feed material is evened out. This makes the performance of the downstream crushing and / or processing plant much more effective.

The quality of the end product and thus the sales revenue is increased.

In the case of in-field screening with our tracked mobile machines, there are no transport routes. Our machines can load both end products directly onto SKWs, so no additional charger is required.

The operator saves the transport of the raw material (including the good rock) to the stationary processing plant and the return transport of the bad material to stockpile.

Separately driven stages:

With each stage, the material falls down, rearranges and is therefore better cleaned.

Basically, every stage is a plus in cleaning effect.

You can choose how many stages your wobbler should have: 1 to 5.

Our standard system 8-4-24 has 4 stages, each with separate drives. These frequency-controlled drives are infinitely variable and controlled by software developed by us. So we can run each stage differently forwards and backwards with automatic detection in the event of overload.

Next back - pilgrimage step for optimal cleaning of the input material.

- Reversing operation direction of rotation of the shafts

- The time forwards and backwards can be set individually

- 5 individual programs are set

- Switchover in the event of an overload

- Start-up under full load (when the hopper is full)

- Infinitely variable, adjustable speed

With set parameters that are specifically tailored to the user, each operator has 5 individual programs. The machine can be operated via a PLC control. The operator can use the remote control to select the programs at any time - while the system is running.

The programs can be adapted again and again. For example, program 1 works with a very high throughput with a lot of forward operation and in program 5 parameters are stored for the processing of very poor material with a long dwell time on the wobbler, a lot of back and forth movement and then with very good cleaning of the coarse grain.

By reversing operation, marl fractions can be loosened or rubbed off on the bedrock

become.

Inclined side walls:

All competing products have vertical walls (trough) on the wobbler. In particular, when “falling over the step”, large material jams and stops the machine.

Posch products have sloping side walls and thus a free fall angle so that blockages do not occur. As a side effect, our machines can feed 50% larger material than the width of the roller grate actually is. Thus, for example, with a wobbler width of 800 mm, material with 1200mm can be feeded.

Heavy construction for feeding material up to 1.800 mm:

The construction of our machines is extremely robust. Each individual shaft is made of solid high-strength heat-treated steel. The discs on the the shafts are made of high-strength Hardox steel. The machine is completely lined with Hardox plates. This robust technology allows stones with an edge length of up to 1.800 mm to be feded.

Feeding directly onto the wobbler:

As a result of our optimizations, the wobbler can now be used for the first time as feeder, because there is no clogging.

Our wobbler is deliberately fed directly onto the shafts using an excavator or loader. A lot of fine material is pressed directly through the "gap" by being fed onto the first stage of the wobbler. With every further feeding, the material on the shafts is moved, pressed and shifted anew. This is how optimal cleaning works. No additional feeder such as apron conveyor or gutter is necessary.

Machines with a guaranteed output of 1.000 t / h:

We have machines in use for which we guarantee a continuous performance guarantee of 1.000 t/h. In extensive tests, this performance guarantee was confirmed and even exceeded by up to 50% -> 1.500 t/h!

Infinitely adjustable screening width possible:

An adjustable gap adjustment can be offered for smaller feed items.

This is not possible when abandoning large rock, as the robust technology does not allow this.

180 ° swiveling stockpile conveyor for fine material:

On our track mounted standard system, you can optionally choose to attach a 180 ° swiveling stockpile conveyor for the fine material. This means that a very large stockpile can be created and the machine can be used very flexibly in combination with other systems in which the belt can discharge to the right, left or back.

Apron conveyor as a discharge device for large stones:

Our mobile systems have a very robust apron conveyor as a discharge device for the large rocks. This technology withstands the tough requirements. A rubber belt strap, as with other suppliers, would be destroyed in a very short time.

Economic benefits:

- Optimal use of resources

- Increase in the performance of downstream crushing and / or processing plants

- Clean pre-screening of unusable materials, thereby increasing the product quality.

- Low energy costs

- Unmanned operation by radio remote control
