Walther Trowal CB 300 vs CB 400: specification comparison
Compare CB 300 and CB 400 in the CB circular vibratory finishing machines official table. Gross volume is 300 versus 400 L; maximum drive power at 1,500 rpm is 4 versus 4 kW. Use the tool to inspect differences, enter your own gross-volume and listed-power limits, and download the current comparison. Conditional volume figures need a workpiece-specific review.
Listed specification differences
| Source field | CB 300 | CB 400 | Right minus left |
|---|---|---|---|
| Gross bowl volume | 300 L | 400 L | 100 L |
| Conditional useful volume | 190 L | 260 L | 70 L |
| Listed maximum workpiece dimension | 220 mm | 260 mm | 40 mm |
| Screen area | 2710 cm² | 3270 cm² | 560 cm² |
| Empty weight | 935 kg | 1150 kg | 215 kg |
| Maximum drive power at 1,500 rpm | 4 kW | 4 kW | 0 kW |
| Maximum centrifugal force | 49000 N | 49000 N | 0 N |
Gross volume increases by 100 L, from 300 to 400 L. The table lists 190 L conditional useful volume for CB 300 and 260 L conditional useful volume for CB 400. These are conditioned by workpiece geometry, material, sensitivity and the media-to-parts ratio; they do not guarantee a batch of parts.
Maximum drive power at 1,500 rpm changes from 4 to 4 kW, a difference of 0 kW. Screen area changes from 2710 to 3270 cm²; empty weight from 935 to 1150 kg. The listed maximum workpiece dimension is 220 versus 260 mm, which alone does not approve a particular part.
Compare with your own catalog limits
Leave both inputs blank to compare the listed values. Enter both limits to include an arithmetic screen. No limit is prefilled. The power field used here is maximum drive power at 1,500 rpm.
Read the volume condition before planning a batch
Gross volume increases by 100 L, from 300 to 400 L. The table lists 190 L conditional useful volume for CB 300 and 260 L conditional useful volume for CB 400. These are conditioned by workpiece geometry, material, sensitivity and the media-to-parts ratio; they do not guarantee a batch of parts.
Parts and media occupy the working mixture together. Do not convert the conditional figure or its endpoints into parts per hour, guaranteed batch weight, packing fraction or a media recipe. Record part geometry, material and sensitivity, then confirm the permissible loading and separation conditions with the supplier and a workpiece-specific trial.
Drive values and source basis
Maximum drive power at 1,500 rpm changes from 4 to 4 kW, a difference of 0 kW. Screen area changes from 2710 to 3270 cm²; empty weight from 935 to 1150 kg. The listed maximum workpiece dimension is 220 versus 260 mm, which alone does not approve a particular part.
The official Walther Trowal CB circular vibratory finishing machines table was captured on 2026-10-04. No manufacturer revision is stated on the HTML table. Listed power is not measured energy use or an estimate of operating cost. Lettered drawing dimensions are not converted to a floor-space rectangle. Obtain current drawings for guarding, service access, utilities and floor loading.

Questions about this pair
What changes between CB 300 and CB 400?
Gross volume increases by 100 L, from 300 to 400 L. The table lists 190 L conditional useful volume for CB 300 and 260 L conditional useful volume for CB 400. These are conditioned by workpiece geometry, material, sensitivity and the media-to-parts ratio; they do not guarantee a batch of parts. Maximum drive power at 1,500 rpm changes from 4 to 4 kW, a difference of 0 kW. Screen area changes from 2710 to 3270 cm²; empty weight from 935 to 1150 kg. The listed maximum workpiece dimension is 220 versus 260 mm, which alone does not approve a particular part.
Does the useful or net volume guarantee a batch of parts?
No. The source conditions the figure on workpiece geometry, material and sensitivity, which determine the media-to-parts ratio. Supplier review and a referenced trial are needed for permissible part load, handling and process conditions.
What do the two optional limits check?
The tool compares gross volume against your entered minimum and the listed power field against your entered maximum. Enter both positive decimal values or leave both blank. A passing arithmetic check is not part-fit, process, electrical, installation or throughput approval.
Are these current specifications or Jintaijin equivalents?
The source is an official HTML table captured on 2026-10-04, with no manufacturer revision stated. Confirm the actual offered configuration and availability with Walther Trowal. These facts do not describe a Jintaijin model or establish equivalence.
