2 The Best Twin-Screw Design for Powder Coating Baker Perkins manufactures a comprehensive range of twin-screw extruders specificay for powder coating production, from the MPX19 for sma batch production, up to the MP80 for outputs of 2,900kg per hour. The extruders have been specificay engineered for the requirements of powder coating, with features that maintain consistent quaity whie keeping running costs ow. They are suitabe for a types of powder coating formuations, incuding epoxy, hybrids, poyester, acryics and fines recycing. Since pioneering the introduction of twin-screw extruders over 40 years ago, Baker Perkins has remained at the forefront of the technoogy and now has an instaed base of over 1,500 extruders wordwide. Baker Perkins has a dedicated team providing Lifetime Support for these machines, incuding repacement screw parts and barres, upgrades, rebuids and training. 2

3 Process In addition to the extruder a compete process ine comprises ingredient mixing and feeding prior to the extruder, with cooing foowed by faking and grinding. Baker Perkins partners with speciay seected suppiers to provide the fu range of equipment necessary to produce a high quaity end product. Each one speciaises in their particuar technoogy so customers are assured of exceent performance throughout the process. Working with partners ensures that the capacities of the individua units are matched and that mechanica and eectrica interfaces are optimised before the equipment arrives on site. Product Discharge Dosing Feeder Nip Ros Product Faking Cooing Coveyor Product Coection Bin or Cose Couped Conveyor System Baker Perkins Twin Screw Extruder Cosed Loop Water System (Optiona) Support from Specification to Optimisation Baker Perkins dedicated industria extrusion team offers support from initia project conception and aboratory trias, through to specification and ine commissioning to ongoing process optimisation advice. Our experts are avaiabe for site visits, product trias and phone support at every stage of a project and beyond, enabing customers to seect and maintain the best extruder for their requirements. Over the ifespan of the extruder, Baker Perkins process support provides: Process Refinement Refined processes for optimised running Superior mixing, screw configurations and cooing profies Enhanced product quaity Process Troubeshooting Adaptation and upgrading of existing equipment Prevent the need for doube-passing of products Identify sources of cratering and pinhoes Eiminate pre-curing of product in the extruder barre Maintenance Advice Longer ifespan through reduced wear Lower running costs Increased throughput and reiabiity 3

4 Features Through-Shaft Cooing Through-shaft cooing increases heat remova from the shafts and screw eements, removing hot spots from the mixing edges. To maintain product quaity and avoid eaks at the shaft coupings, the cooed water is fed from the rear of the gearbox, rather than introduced at either end of the agitator shafts. This unique soution increases reiabiity and ceaniness and avoids compications such as contamination from eaks, as we as ensuring uniform cooing and eiminating hot spots inked to temperature sensitive materias. Advanced Heating & Cooing Eectric cast sab heaters and advanced water cooing within the barre work simutaneousy to provide consistent temperature contro. The easy-to-repace sab heaters have eectrica eements cast in an auminium housing to aid accurate temperature contro of the barre. Specific Power & Torque Unike muti-purpose extruders, Baker Perkins motors are specificay seected for powder coating appications. By specifying the precise power and torque for this appication, output can be maximised without wasting energy. The extruder s efficiency and ifespan is increased by reducing wear, and ong term maintenance costs are cut. Instaation costs are aso owered as a smaer power suppy is required. Torque Protection Torque is constanty managed by the contro system to operate within defined preset eves. A torque imiter creates a faisafe mechanism to protect the drive train in the event of a sudden overoad. 4

5 Optiona High Intake Feed Port Contributes to higher throughput for ow density materias. The feed port area has been redesigned to aow materia to enter the extruder quicky and eveny, reducing the risk of backing up creating torque fuctuations. Gearbox Condition Monitoring System A condition monitoring system aows owners to easiy observe their gearbox s condition, avoiding the costs of unexpected downtime and improving maintenance scheduing. Easy to sef-monitor and pre-caibrated for Baker Perkins gearboxes, the system fiters unwanted frequencies and consoidates information into a simpe traffic ight system that highights when the extruder is running within recommended imits and when attention may be required. Gearbox Superior, durabe bearings excusive to Baker Perkins gearboxes increase reiabiity and provide an industry eading service factor that resuts in a onger ifespan and reduced maintenance costs. Contros Deveoped specificay for the compete range of Baker Perkins extruders, a touch-screen HMI provides cear, at-a-gance visuaisation of the process, incuding current status of a major components and parameters. Aarm management means that the operator can immediatey identify and ocate probems. Automatic management of recipe settings ensures exact, unvarying repication of product, eiminating quaity variations caused by operator error, whie a data coection system records a key process variabes. 5

6 Range MPX19 Laboratory Extruder The MPX19 is a benchtop twin-screw extruder idea for aboratory and deveopment work. The MPX19 features Baker Perkins cam-she barre, so production can be stopped at any time with immediate access to view the state of materia being processed. It deivers repeatabe resuts, and enabes fu, reiabe scae-up to production outputs on Baker Perkins range of arger extruders. MPX24 Integra Sma Batch Production Extruder The MPX24 Integra is a sma batch production extruder designed specificay for thermoset appications. A chi ro and faking unit are fuy integrated into the machine for a compete process in a portabe machine. Its compact design means that it can be used either in a aboratory for new product deveopment or in a production environment for tasks such as coour matching and sma batch production. In a instances the MPX24 Integra deivers repeatabe resuts that can be consistenty reproduced on production scae machines. This ensures that the desired resuts are obtained first time, thereby improving quaity and reducing costs. MP30 MP80 Production Extruders A comprehensive range of twin-screw extruders for appications from sma batch (100kg/hr) up to high-output (2,000kg/hr) continuous production. The extruders have been specificay engineered with features that hep to maintain consistent quaity whie keeping running costs ow. The high torque-capacity, high free-voume geometry and uniform barre heating ensure that consistency is maintained under a operating conditions. Quick start-up, reiabe operation and rapid changeover keep operating costs ow. A wear parts are ong-asting and easiy repaced and when combined with the utra-ow maintenance drive train resut in minima maintenance costs.
