RING MILL BOWLS1 of 3A unique range of bowls from 10 to 2000cc nominal capacityThe Labtech Essa programme of ring mill bowls is unique because it includes 3 sizes ofinternationally patented high capacity and performance bowls together with a range oftraditional ring and roller type bowls.The patented bowls consist of a single,solid “flying saucer” shaped puckoperating in a bowl with a concavecurved bottom surface. The mass ofthis single puck in combination with thespatula like grinding interaction between its lower curved surface and thatof the bowl provides superior pulverising with grinding performance. Thepuck also has an off-centre, truncatedhole through it to assist in the mixing ofthe sample to assure homogeniety.These bowls are of through hardenedsteel construction for optimum life. Theyare available in 800, 1000 & 2000ccnominal capacity.Labtech Essa unique patented solid“flying saucer” shaped puckLabtech Essa traditional ring and roller style bowls are available in 50, 100, 125, 300 &400cc nominal capacity. These too are of through hardened steel construction as standard,with optional materials available on request.All bowls in this range are suitable for use on the Labtech Essa model LM1, LM1.5 andLM2 mills as set out on page 2 of this data sheet (see separate data sheets for mill details).Ring and roller bowls can be used as replacements for those from other manufacturers.The patented bowls typically have the ability (when used on a Labtech Essa mill) to reduceores, minerals, metallurgical samples, ceramics, soils, aggregates, chemicals and similarparticulates to a nominal 75µ product in approximately 3 minutes; with the ring and rollerrange typically capable of producing an even finer product in approximately 1 to 3 minutes.The useable capacity of each bowl will generally be 60 to 80% of its nominal capacity. Theperformance expectation of all bowls is subject to the physical characteristics of the samplebeing milled and the final particle sizing required.Labtech Essa are pleased to be able to conductpre-purchase trials on customer supplied samplesLabtechEssawww.labtechessa.com.auLabtech Essa Pty Ltd8 Yelland Way, BassendeanWestern Australia 6054, AustraliaPhone: 61 (08) 93773677Fax: 61 (08) 93773420email: mail@ labtechessa.com.auApril 2002

MODEL LM5Laboratory Ring Mill1 of 2Vibratory ring mill for preparing up to3.5kg of ore for mineral for analysisThe Labtech Essa model LM5 mill is used for pulverisingores, minerals, soils, metallurgical samples, ceramics,aggregates, chemicals and similar particulates. It findsparticular application in mineral laboratories needing toprepare larger, more representative samples. Typically,samples of approximately 3 to 3.5 kg mass can beground to 90 to 95% minus 75 micron, while largersamples up to approximately 4 to 5 kg can be reduced toapproximately 0.5 to 0.8 mm particle size (all subject tothe physical characteristics of the material. and thecondition of the grinding elements). Grinding time will beapproximately 5 to 8 minutes.Labtech Essa are pleased to conduct pre-purchase trialson customer free supplied samples.PLEASE ASK FOR OUR DEMONSTRATION VIDEOThe vibratory platform of the model LM5 is driven by a universal shaft powered by vee-belts from astandard, stationary (non-vibrating) 4 kW electric motor. This arrangement delivers the powerrequired to drive the large 5 kg nominal capacity grinding bowl integrated in to the head of the mill.The drive motor is inherently protected from direct vibrational loads.The design of the bowl is based on Labtech Essa internationally patented concept of a single, solid“flying saucer” shaped puck operating in a curved bottom bowl. Only the puck is removed from thebowl during routine operation. A pneumatically actuated “MILLMATE ” hoist is fitted as standard toassist in lifting and lowering the puck. The bowl is filled and emptied manually. Residue is vacuumed from the bowl. A vacuum gun is supplied as standard with each mill for connection to thecustomer’s dust extraction system.TEDA CHTA NI: CALSTANDARD FEATURES: Pneumatic bowl lid clamping. 4 kW stationary electric motor drive. 415 Volt, 50hz, 3 phase power Good looking, easy to clean fibreglasscabinet with sound reducing foam lining External control box with start & stopPower requirementpush button, motor overload protection,electronic run cycle timer and pneumatic failure protection.

MODEL LM5Laboratory Ring Mill2 of 2The pulverising bowl of the Labtech Essa model LM5 mill is permanently attached to the vibratingplatform of the mill during all normal operations. Only the puck is removed; with the aid of thepneumatically actuated MILLMATE . The bowl is filled and emptied manually.Residue is vacuumed from the bowl. A vacuum gun assembly is supplied as standard for thispurpose, together with 3 metres of flexible hose for connection to the customer’s dust collectionsystem. Some customers prefer to connect direct to their dust collection system with an openended flexible hose as shown in the photo at the bottom ofthis page and in our demonstration video.The design of the bowl is based on Labtech Essa internationally patented concept of a single, solid “flying saucer”shaped puck operating in a curved bottom bowl. Thisconcept is recognised to produce a homogeneous samplewhich only requires a portion of the milled sample to beretained for analytical purposes.The Labtech Essa model LM5 mill is housed in a durableand good looking fibreglass cabinet lined with soundabsorbing foam. A dust extractionpoint is provided at the rear of thecabinet.The front half of the cabinet isquickly and easily removed formaintenance access. Majormaintenance is facilitated by theability to remove the mill from thecabinet while leaving the cabinetand MILLMATE in their installed location. Sample preparation facilities with multiple numbers of mills make use of thiscapability to quickly install aspare mill while the original istaken to the workshop.LM5 mills installed at a commercial assay laboratoryin Kalgoorlie, Western Australia.
