(DCS) recently completed the installation and commissioning of the second dust removal system for the MDF molding equipment of Arbor Forest Products at Arbor Forest Products’ New Holland headquarters in North Lincolnshire.
DCS has installed extraction equipment for
Production of its first MDF molding unit started in early 2014, and the new capacity of the new £2.8 million rolling mill will double the capacity-further achieving the company's goal of becoming the leading supplier of MDF molding in the UK market. Advanced high-throughput manufacturing plants will inevitably generate a large amount of MDF waste, and the successful installation of the previous extraction equipment is a key factor in deciding to award the contract for the second system to DCS Ltd.
The core of the new system is a 75kW main fan driven by a clean-side inverter. The main fan is drawn into the DCS cyclone filter and can purify 45,000 cubic meters of air per hour. It has a height of 10m and a diameter of about 4m. The sturdy welded steel structure and six ATEX-certified explosion-proof panels ensure that the DCS cyclone can safely handle potentially explosive dust.
Melvyn Bathgate, Sales Director of Dust Control Systems, explained: “Cyclone filtration is very suitable for continuous operation processes, during which a large amount of dust-laden air is generated. The model installed on Arbor Forest can collect up to 1000kg of dust per hour. Through the initial cyclone separation, more than 95% of the waste can be removed, which will fall into the cone hopper."
Residual dust is filtered from the circulating air through a patented tubular filter bag. The efficiency of the polyester anti-static needle felt bag is maintained by the powerful reverse jet cleaning system, and has the function of automatically managing the cleaning cycle online. This two-stage collection process can achieve extremely high filtration efficiency, and the purified air (which can be transferred back to the factory or discharged into the atmosphere) contains up to 0.1mg of dust per cubic meter.
All waste collected at the bottom of the hopper section is discharged pressurelessly through the rotary valve, and the closed-loop transmission system sends the waste directly to the bulk collection trailer from there, or manually transfers the waste to a nearby waste collection station when needed. Storage bin with a capacity of 50m3. As in the previous installation, the silo has a diameter of 4m, has a conical base, and has dual rotary valves. The main valve feeds the closed-loop transmission system, which directs the waste to a collection trailer and discharges it a second time to the emergency screw conveyor.
Melvyn Bathgate further commented on the installation situation: “DCS will never compromise safety and always install the CARZ back pressure valve before the filter inlet. The CARZ valve is ATEX certified. In the event of an explosion, It is designed to prevent the influence of pressure waves and flames from returning to the factory along the piping system where it is installed.
Gwyn Tuxford, the MDF manager of Arbor Forest Products, has worked in the company for 20 years. He commented: "The air extraction system installed by DCS for MDF Mill 1 has been It is trouble-free and almost provides us with a dust-free environment-we now look forward to maintaining the same working conditions in the new factory."
Finally, Mr. Tuxford added: "Melvyn and the DCS team provide first-class services-from specification to commissioning, the installation of the MDF Mill 2 air extraction system, including the complete piping system, was completed in just 10 days."
