POLYSIUS AG is notresponsible for any damage resulting from any other than the intended use of the machine. All other use is at the owner’s own risk.POLYSIUS AG •The intended use also includes observance of instructions in the machine manual and the conditions for maintenance.Transport and assembly•All transportation instructions in this machine manual refer exclusively to transportation of the machine at the plant site. •Only use suitable hoisting gears and load-carrying equipment which is suitable and technically serviceable and has a sufficient load bearing capacity. • Never work under a suspended load.Operation• Any safety checks before or during operation depend on the relevant nationalregulations. The plant management is responsible for the performance and recording of such safety checks..•If changes in the machine or its operating behaviour relevant to safety occur,shut down the machine immediately.EN22421.003AMaintenance•Please observe also the safety instructions concerning the roller mill. • Ensure that for the entire duration of the maintenance work, all machines andmotors whose operation might endanger persons or equipment are switched off and safeguarded against restarting.• Ensure that all rotating parts of the machine have come to a standstill before you remove protection devices or open covers.• Before work is performed on the machine, ensure that there is no danger that persons touching the machine will burn themselves. Ensure that there is no hot material inside the machine when inspection and maintenance covers are opened.• Keep the machine free from oily and combustible materials. Never usegasoline or other easily inflammable substances for cleaning the machine.• Switch off the power supply to the electrical components before commencing any maintenance work.• After all maintenance work, check that there are no leaks in connecting points and connections.• Strictly observe the welding instructions when performing any welding work.•Never situate the source of the welding current in a confined space where walls have conductive properties. Only use 24–Volt lamps for illuminating the interior.24–Volt• If you carry out electrical welding on any part of the machine, never conductthe welding current through plain or antifriction bearings, other movable connections or measuring devices. Always directly connect the welding current return lead to the part being welded.•Remount all protection devices when maintenance work has been finished.Make absolutely sure that no persons are inside the plant component before you properly close the inspection and maintenance covers.EN22421.003A3 Components and description of functionningThe housing of the roller mill is designed in two parts.For inspection, maintenance and assembly work, the upper housing section isprovided with great doors.The areas of the housing which are particularly subjected to wear are protectedby exchangeable wearing plates.The hot gas channel around the inside of the lower section of the housing servesfor a uniform distribution of drying gas. The nozzle ring is designed for guiding thehot gas stream in the upper housing section. The seal between the lower housingsection and the grinding table is designed as a sliding contact seal.In the area of the tie rod passage a self-adjusting seal prevents any leakage ofmaterial being ground.The feed chute is protected by exchangeable wearing plates.The nozzle ring is the …bottleneck… in the roller mill. Here, the gas stream emergesat a high velocity, takes up the crushed material falling off the grinding table andcarries it upwards to the separator.3.1 ComponentsNOTESome details of the drawings in this manual may not be identical with the dra-wings supplied under the contract as listed in the section 9.1 Technical drawings.The housing consists inter alia of the•lower housing section •upper housing section with the doors •hot gas connection• nozzle ringEN22421.003AItems shown in the drawing of the housing2Hot gas connection 5Material guide plate 8Guide bracket 8.1Wearing plates for the guide bracket 9Nozzle ring 10Upper housing section 11DoorFigure 1 1Figure 2 c =guide pin of the roller pair unitEN22421.003AItems shown in the drawing of the housing1Lower housing section 2Hot gas connection 3Discharge device 3.1Wearing ring, below 3.2Wearing ring 3.3Cone lining 3.4Scraper reclaimer 3.5Driver plate 4Discharge connection for material recirculating by bucket elevator 4.1Wear protection for discharge connection 6Seal for the grinding table 7Wear protection in the lower housing section 9Nozzle ring 10Upper housing section 11Door 12Wearing plate in the upper housing section 14Seal for the tie rod assembly 15Terminal box for the confining air pipe 15.1Inspection cover b Grinding tableFigure 3 3EN22421.003AItems shown in the drawing of the nozzle ring (9)9.1Nozzle ring adjusting device 9.2Adjustable segment of nozzle ring 9.3Nozzle ring segment (internal)Figure 4 4EN22421.003A4Transport and assembly 4.1 Transport and storage instructionsThe machine is transported in single parts or in sub–assemblies. Make absolutelysure that suitable lifting equipment is employed in removing the parts from thetransport vehicles and transferring to the storage area.When they arrive at the site, all parts must be inspected for transport damage andplaced on wooden beams with the provision of suitable protection against moisture,contamination and damage. Never store the parts directly on the ground.4.2 AssemblyGeneral informationThe following assembly instructions do not detail the individual steps forassembling the units, but rather give an overview of the work to be performed.Differences in the design of the plants may lead to deviations from these assemblyinstructions.NOTEIt is a prerequisite of our warranty that final assembly and assembly inspection areundertaken by an assembly specialist from POLYSIUS AG.POLYSIUS AGWe recommend that an assembly specialist from POLYSIUS AG supervises thework from start to finish.POLYSIUS AGCareful selection of tools and appliances used and of the personnel is important forthe correct execution of the assembly work.CAUTIONIf electrical welding is carried out in any place of the machine, weldingcurrent must never be conducted through friction and antifriction bearings,other movable connections or measuring equipment to prevent damage to such parts.Always directly connect the welding current return lead to the part being welded.EN22421.003AMeasuring workElevation reference pointThe point of reference of all measuring work is the elevation reference pointauthoritative for the whole plant, which is fixed in relation to the zero datum linestated in the general arrangement drawing. The companies responsible forconstruction of the foundations and buildings determine the elevation referencepoint and inform our erection superintendent accordingly.To facilitate the measurements of axis and elevation for the erection of themachinery parts, the level of e.g. 1000 mm above zero datum line is marked on thefoundations of the mill and drive unit. For this purpose, steel plates of 200 x 200mm size were anchored in the foundation by the building contractor. Into theseplates, the elevation determined by means of a levelling instrument or a rubbertube level is permanently chiselled.Figure 5 5A=Datum mark B=Steel plate C=Anchorage D=Concrete E =Drilled hole for nailed connection to formworkTightening torque for boltsIf not stated otherwise in the drawings, the following specifications apply:•The tightening torque is applicable for bolts according to DIN EN 24014 and DIN EN 24017 of quality grade 8.8 • Threads and contact surfaces must be cleanAbbreviationsSWWidth across flats in mm mm MaTightening torque in Nm Nm Fv Pretensioning force in kN (for hydraulic pretensioning unit)KN dry = 0,15oiled = 0,13bolts SW Ma FvMa Fv M 16M 16 x 1,5242420321261.864.618219363.068.2M 20M 20 x 2303039541096.299.936037099.8102.5M 24M 24 x 2M 24 x 1,5363636690730750140.1148.2152.3620660680143.2152.4157.0M 30M 30 x 2464614001500228.4244.712501350232.2250.7M 36M 36 x 3555524002500327.3340.921502250334.0349.5M 42M 42 x 3656538004000445.1468.634503600460.5480.6M 48M 48 x 3757557006100585.2626.352005500608.5643.7M 56M 56 x 4858592009600812.2847.583008600835.8866.0M 64M 64 x 4959514000147001084.11157.912500130001104.61148.8M 72 x 6M 72 x 410510520000210001384.41453.718000190001423.61502.7M 80 x 6M 80 x 411511528000290001752.31814.925000260001789.31860.9EN22421.003AM 90 x 6M 90 x 413013041000420002291.32347.136000375002302.92398.9M 100 x 6M 100 x 414514556000590002826.93011.450000520002891.43007.1Assembly of the housing-Check the mill foundations for dimensional accuracy according to the generalarrangement drawing and the construction drawing.-Mark the longitudinal and transverse axes on the mill foundations and the steelstructure of the building.
