Dust extractor SMU
Dust extractors are used to extract dust from one or more processing machines. The extraction volume flows of the dust extractor range are between 1,200 and 10,000 m³/h and therefore are primary solution alternatives for joinery and carpentry companies. However, they also represent an ideal supplement to existing central extraction systems if the machine park is expanded and the existing filter system has no reserve capacity.
By combining dust extractors, stationary filter systems can also be replaced. This concept is applied when, due to local conditions at the customer's premises, filter systems cannot be installed outside of buildings and the alternative solution of arranging the filter system indoors and equipping it with flameless pressure relief is not feasible for structural reasons. 2, 3 or 4 dust extractors installed in the workshop form the extraction centre, which provides air capacities of maximum 20,000 m³/h, 30,000 m³/h or 40,000 m³/h.
The possible applications are many and varied. Decentralised extraction solutions can also be advantageous in terms of energy efficiency due to the installation of the dedusting system close to the machine, compared to a central extraction system with long pipelines to the filter system. When planning the plant, the individual aspects and factors must be weighed up in order to select the optimum plant configuration for the individual case.
With dust extractors which are tested by the BGHM trade association and have been awarded the DGUV test certificate (H3) and the GS mark, chips and dust of various materials can be extracted and compacted, for example in combination with a briquetting press:
- other metals.
The chips and dust must be dry and the KSt-value must be ≤ 200 bar bar . m/s (dust explosion class St1) The KSt-value is an explosion-technical parameter, which is determined by dust analyses.
The scope of application of the dust extractors has been extended based on the new European Standard Fpr EN 16770. In future, dust extractors with volume flows of more than 6,000 m³/h for the extraction of organic dusts, dust explosion class St 1, may be installed directly in the working area due to their design. The advantages of extraction systems based on dust extractors will thus benefit a larger circle of users:
- Shorter piping distances reduce investment and operating costs.
- Expensive return air duct systems are not required.
- One hundred percent heat recovery is achieved through direct air recirculation.
- The delivery of the unit as far as possible ready for operation leads to short installation times and thus low installation costs.
SPÄNEX dust collectors convince by high performance, best energy efficiency, quiet operation, compactness and easy handling.
High suction power
- Low energy consumption
- Quiet operation
- Effective filter and cleaning technology
- Appealing design
- Compact housing dimensions
- Tested safety
- Several disposal options
The dust extractors are delivered largely ready for operation and for the most part mobile, so that they can be easily brought in and set up in the working area. As standard, the dust extractors are supplied with 1 to 3 filling bins with inserted plastic bags. For the larger dust extractors (from SMU 32 upwards), the combination with a briquetting press is a frequently chosen variant. The design of the briquetting presses series SHB 40 / 55 and SHB RS 55/70 has been specially adapted for use in combination with the dust extractors. The machines are arranged directly below the container to save space.
For applications with very large chip quantities, the dust extractors with container and attached rotary valve are available as a further design variant. The chips separated in the container are transferred via a discharging unit and the rotary valve to a screw or pneumatic conveyor system and conveyed into a container or silo located outdoors.
- Automatic start of the fan
- Automatic slide control
- Operation via frequency converter
- Filling level monitoring in the containers with briquetting press or container feeding or silo feeding
- With briquetting press or external container
- Automatic extinguishing system with powder extinguishing
- Ignition protection system
