2GB/T17671-2021 new standard cement mortar mixer compaction tablework procedure

2.1 There are two modes available: manual and automatic

2.2 The automatic control program is as follows: low speed for 30s ± 1s, then low speed for 30s ± 1s, and automatically start adding sand and complete it within 20s to 30s. High speed for 30s ± 1s, stop for 90s ± 1s, and high speed for 60s ± 1s.

2.3 Manual control has high, stop, and low speed and sanding function control buttons, and is interlocked with automatic control.
