His primary expertise is in dust separation equipment, including dust collectors, baghouses, cartridge collectors, dust filters and cyclones. Expert has worked for four different companies that manufactured and installed dust separation equipment. His design experience includes pulse jet collectors, low pressure high volume round collectors, cartridge collectors and cyclones. Expert is experienced in design, application and sizing, system layouts and turnkey projects. He also has extensive knowledge on various control systems and protocols for dust collection systems and multiple banks of dust collectors as seen in power plants. He is also very familiar with the various types of dust processing equipment to transfer the dust from the collector to its final destination. This experience includes pneumatic conveying dilute phase, airlocks, double dump valves, and mechanical conveyors.

Expert's experience in dust collector design application selection have required him to become an expert in dust explosion hazards and dust explosion venting. He is very familiar with the NFPA guidelines that cover dust explosion hazards. Expert has applied guidelines and calculations found in NFPA 13, NFPA 68, NFPA 69, NFPA 484, NFPA 654 and NFPA 664.

Mikes expertise with industrial exhaust systems and design encompasses almost 30 years of his employment experience. His design experience is focused on dust collection systems and pneumatic conveying systems. He is capable of doing complete system layouts, static balancing, hood design and air mover selection. His dust handling experience spans from capturing dust at the source, separating it in a filter or mechanical separator and conveying it from the separator to the storage equipment. This experience also makes him a good choice for solving problems with existing systems or planning expansion of existing systems.

Expert has been involved in designing and selecting centrifugal blowers throughout his career. Prior to becoming an engineer, he did CAD work designing a line of heavy duty paper handling blowers. Since then his career in air filtration and dust collection systems and equipment design has kept him in a position to select, specify and purchase centrifugal blowers for a multitude of applications.

Expert is proficient in AutoCAD, Solidworks and Cosmos computer aided design software.

Throughout Expert's career he has been involved in manufacturing. His first design job consisted of designing weldments in the 80's before computer aided design was available. He excelled at sheet metal layout techniques such as triangulation. He has created design patterns for weldments weighing from 5 lbs up to 2 tons per piece. Later employment involved design of round baghouse filters up to 20 ft diameter that went on a Gold mining project in Nevada. Expert always listened to the people who assembled his designs because that is the best way to improve the design. Other design experience included injection molded plastic parts and plastic and aluminum extrusions. In a most recent project Expert was able to reduce warrantee costs of a product line by 85% through design for assembly and manufacturability. This was accomplished by paying attention to the problems of the assembly department and service department and implementing their ideas and solving their problems.

Expert is a Professional Mechanical Engineer. He is strong in mechanical assemblies, drives, weldments and fabrications, pneumatic devices and controls, PLC controls, P&ID diagrams, industrial dust collection system and component design, fans, pumps, injection molded plastics, aluminum and plastic extrusions and failure analysis. He passed the PE exam in 99 and was honored with the highest score on the engineer in training exam during college. Expert also has a strong electrical background and lack only one semester from obtaining an electrical engineering degree.

Expert's career has been focused around industrial air filtration systems and equipment. To properly design/select the proper system and equipment, knowledge about the dust must be obtained. To properly select a baghouse filter or cartridge filter you need to know the type of dust, the particle distribution, the rate of flow of the dust along with other process information like temperature and humidity. Other characteristics of the dust that must be evaluated include adhesive and cohesive nature, hygroscopic tendencies, particle shape and its abrasive characteristics. Years of dust collector and system design have help Expert become an expert in this area.

Industrial air pollution and industrial air quality for a factory are directly related to dust control in a factory environment. Expert has been involved in this field since high school. His abilities/experience range from design of source capture devices, filtration equipment, piping systems, and dust transfer systems. Dust in a factory can also become a fire or explosion hazard. Identifying this hazard and providing solutions to eliminate it are also among the many strengths that Expert has acquired through experience.

One of the biggest advancements in industrial dust collection in the last 30 years has been improvements to the filter fabrics. Expert's experience designing dust collectors and specifying proper filter media for an application over the years required him to stay abreast of current filter fabric technology. Expert currently contracts with one of the premier filter fabric manufacturers in America.

Expert is currently serving on the NFPA committee for Handling and Conveying of Dusts, Vapors, and Gases (CMD-HAP). This committee controls NFPA 654, 655 and 91. Expert is experienced with all of the NFPA combustible dust standards. Expert currently uses his knowledge in this area to train associates and customers with respect to the combustible dust standards. Expert has published several white papers on the subject.

Expert is working with a Northeastern public power company to fix problems with the ash removal system and problems with wear on bags for an 8 compartment baghouse on a biofuel boiler. Expert is helping a filter manufacturer design and build a test system to test efficiency of a dust collector per forthcoming ASHREA standards. Expert worked with a sign company that makes changeable message signs for toolbooths. The goal was to improve the design and reduce costs. Expert has worked as a contract estimator for a local company on some projects that they did not have the manpower to get to. Expert created automated quote spreadsheets for a local powder paint company.

Expert may consult nationally and internationally, and is also local to the following cities: Memphis, Tennessee - Jonesboro, Arkansas

Marketing Experience
Expert's experience with four different dust collection equipment manufacturers gives him a unique understanding of how this equipment differs and how different manufactures have claims of performance that may or may not be beneficial to the end user. The industry is dominated by internal manufacturer experience that is not taught at any university. Customers should be aware of this because industrial dust collection is often referred to as a black art within the industry. An objective review of bid documents and equipment selection can go a long way in saving money and avoiding a problem installation.
