3.1 SupplierIt is determined after purchase contract of equipments, so its item is described after confirming 1st vendor print.

3.2 No. ReqdIt means the number of the equipments and the unit. If required, the stand-by It is determined after purchase contract of equipments, so its item is described after confirming 1st vendor print.4OPERATING CONDITIONS

Mainly the data related with the process is described fully.

4.1 Material HandledIt is the treated material to be transported. If there are multiple materials, their analytical method is needed. Each the component of raw materials is expressed as %WT or % VOL If the space is not enough, mark the Remark No. at the blank and describe at the below remarks space.

4.2 Density (Bulk/Real)For transportation of raw material, generally bulk density is needed. And because real density is not usually used, only bulk density is noted. But if raw material is powder, real density must be marked. In case of mixed material, average bulk density is marked as AVG if possible. If average density is unknown, both min. and max. densities must be marked.

4.3 Particle SizeIn case of the transportation, particle size is mainly marked as MM. If it is powder, Taylor mesh or micron is used instead of MM. If the particle distribution is uneven, it is noted as %WT or %VOL. In that case, remarks no is noted and it is noted below remark space in detail.

4.4 Lump Size Max.For bucket elevator sometimes lump raw material is transported, the size of lump and the maximum size of it are noted.

4.5Moisture contentIf transported materials are exposed to ATM, it means containing moisture as weight %. It is nearly not happen that material itself has moisture, the percent of moisture contents expressed as max value like 1 % weight below.

4.6 Feed TemperatureIt is the temperature when raw material is fed into elevator, If not, treat in the prior process, ambient temp. is noted.

4.7 Operating TypeOperating type is composed of continuous or intermittent and auto start/stop or manual start/stop as showed on the data sheet. If the special operating type, it is noted on the remark space. Whether start/stop type is automatic or manual, it is necessary to confirm the supply of start/stop push button box. For all equipments at the start of project, it is necessary that the determination between form each vendor and from instrument engineering team. If automatic, it is necessary to confirm the needs of remote switch on the local push button box. If continuous on-off operation, it is noted in the remarks space. (For example, on-Off cycle time: 3min.)

4.8 Operating TimeIt is expressed as operating cycle, means the operating time per day. It is related with the plant operating time of client. If 2-shift, it is 16Hr/day. If 3-shift, it is 24Hr/day.

4.9 CapacityIt is the ability of transportation. The capacity is described as normal and design value on the data sheet. The normal capacity is mandatory. Design capacity can be the rated capacity in the equipment detail design and motor power calculation to vender. So, except for case of process needed design capacity or case that added capacity margin in the request of client, 10% margin of the normal capacity should generally be added.

4.10 Method of LoadingAs a method of feeding raw material to the elevator, it is good to describe the method related with the prior equipment on the layout. Also, feeding type should be clarified among continuous, dump, and batch. Mainly bucket elevator is continuous because of feeding by chute.

4.11 Material PropertiesIt means the chemical and physical properties of the transported material as an engineering view. It is good to select the related property on the data sheet. If there is need to express the power of property, select it and it is reasonable to mark the high or severe at the blank. If multiple properties are given, select and mark multiple options. If no listed properties, select other option, and describe it.

4.12 InstallationIt means the construction location of equipments on the lay out, either indoor or outdoor. If extra condition like under roof, make a note.

5CONSTRUCTIONS

It shows the equipment structure and specification.

Only process options are marked, the others are marked by vendor.

5.1 TypeThe type of bucket elevator is expressed on the data sheet, so just select the multiple options.

(1)Vertical and InclinedIt means that whether elevator is vertical or inclined from floor, inclined type is expressed with degree.

(2) Centrifugal and ContinuousIt means how to discharge the raw materials.

According to the method, the attachment method of bucket is fixed.

(3) Self-supported and SupportedIt means whether an elevator body is supported or not.

5.2 Bucket Type, Pitch, Speed and SizeBucket has various types according to the kinds and properties of raw material. It is chosen by vendor. (Refer to link-belt catalog) Also pitch, speed and size are decided according to bucket capacity.

5.3 Bucket EfficiencyThe efficiency is the process requirement. Generally 75% is applicable.

5.4 Bucket AttachmentIt means where buckets are attached. Select between belt and chain on the data sheet.

5.5 Elevator ArrangementThe purpose of an elevator is the vertical transportation; the elevator arrangement is enough to the vertical elevation; The length the distance between shaft (pulley) center lines or between feed and discharge. Overall height is determined by vendor.

5.6 PulleyIf necessary, the type is specified. (Refer to link-belt catalog)

5.7 BearingThe bearing is based on vendor standard, and lubrication is determined by vendor's recommendation.5.8 Chain Type, Pitch and AttachmentThey are determined by vendor's standards.

5.9 BeltBecause it should refer to belt conveyor, it is omitted here.

If possible, Ply and splice type are specified.

5.10 Back StopIt is necessary to the bucket elevator. Because it is related with cost, select only type. Rating, speed, temps. Range and service factor are determined by vendor.

5.11 Take-upChoose between screw and gravity.

5.12 InsulationIt is determined by process

5.13 WeightIt is informed by vendor.

6MATERIALS

It is general that the materials are fixed according to the properties of the raw material and the operating purpose. The material contacted with raw material on process should be specified. At least, bucket and casing materials are fixed; the others are fixed by vendor. The selection of the materials is fixed by referring the material properties on operating condition. When the bucket material is erosive material, hard surface bucket or casting is used

7DRIVER

If normal, supplied-by/mounted-by is fixed by vendor.

Because the things with drivers are fixed by other detail associating teams, the driver needs not to be fixed by process engineering team. So no needs, no marks.

7.1 ManufacturerIt means the manufacturer of motor.

In no case of elevator split supply, it is fixed up by vendor.

But specific motor manufacturer is fixed in advance by operation and maintenance on client's requirements

7.2 TypeThe type of motor is fixed by TEFC, but at the start of project it is fixed by the electrical specification

7.3 Rated OutputIt means the rated output of motor, it determined according to it capacity by vendor.

7.4 PoleIt is the number of the motor's rotation, fixed by vendor.

7.5 RPM

It is the RPM of motor, and it is decided according to voltage by pole.

7.6 Phase, Cycle, VoltsThe phase, cycle, and volts are fixed up at the start of project in all plants, and are given from electrical specification or utility supply condition.

7.7 Rated AmpereIt is reference data from vendor.

7.8 ReducerBecause of geared motor, the type of reducer can be not necessary. But if reducers are needed, it is specified by vendor. The rating is fixed up according to the rated output of the motor by vendor.

7.9 CouplingIf the geared motor is used, the coupling is useless.If the reducer is needed, the couple is useful.

The rating is fixed more than the output torque of motor by vendor.

7.10 TransmissionIt linked with the reducer and the shaft of the elevator. Mainly it is chain & sprocket type. Type, rating and ratio are fixed up by vendor.

7.11LubricationIt is lubrication about reducer, motor and coupling specified by vendor.

8ACCESSORIES

Because the supply scope of accessories is related with the supply scope of the equipments and fixed up according to operation/system. it can fixed up at the process data description possibly. They are specified if fully explainable as process requirements and special requirements. So, it is possible that the detail associated teams select them.

8.1 Platform and Ladder with Handrail, Safety CageThey should be equipped on the bucket elevator.

8.2 Motion SwitchIt is for remote-monitoring of elevators' operating condition equipped on tail pulley.

8.3 Chain Block and SupportIt is equipped on the bucket elevator for maintenance of motors and reducers.

8.4 Access and Working DoorAn access door is for inspection or maintenance, a working door is relatively large-equipped door for the exchange of buckets.
