Thank you for your feedback. First, please see the image: on August 22, you placed the order on Alibaba yourself and selected the chainless option and the cheaper multimodal transport (sea freight). Second, our products come in various sizes/materials/with or without a chain, etc.; please see the photos. Finally, before placing the order, you did not contact us to tell us your exact requirements. We completed shipment on August 26 in accordance with the requirements and transport method selected in your order. I suggest that before purchasing on Alibaba, you contact the seller in advance and inform them of your requirements. If you need the version with a chain, we can re-quote you our best price and offer you a certain discount.

We took this issue into consideration. Before manufacturing the sifter, we tested meshes with different mesh counts. With a coarser mesh, there is very little waste, but it cannot achieve the desired filtration effect. With a finer mesh, there is more waste. Therefore, the current mesh count is the best.
