CUTTING SYSTEM

Special cutting design : All the steel wire columns are fixed on two main oblique  beams of cutting machine and each pair of the columns is used to fix only one steel wire , so that the horizontal  cutting machine can avoid the settlement cracks problem in thin block and panel cutting , and achieve the minimum horizontal cutting thickness of 50MM block out of a whole mould. The integral swing frame of the vertical cutting machine can ensure the side plate replacement , the cutting action can be synchronized with ferry replacement. With automatic detection system . the broken wire can be timely detected.

PACKING SYSTEM

Automatic packing system can realize the automatic rotation stacking and splicing of blocks and  realize the packing function with pallet or non-pallet. The stacking specification can realize 1.2m×0.6m\ 1.2m×1m\ 1.2m×12m\ 1m×0.6m multiple  stacking , and the height of the stacking can be 1.2m, 1.5m , 1.8m and 2.4m.
