塞拉利昂采购需求：砌块机，混凝土砌块机，砖机，砌块制造机，砌块制造设备，砌块成型机

We are looking to procure a block-making machine capable of producing between 20,000 to 30,000 standard hollow blocks in an 8-hour workday. The specific block types we are interested in include hollow, solid, and paving blocks. The color of the blocks is not a concern, so any standard color options will be acceptable. Our preference is for a semi-automatic machine that comes equipped with a PLC (Programmable Logic Controller) system, along with an integrated mixer. Additionally, we require the machine to include the appropriate wheelbarrow and other necessary operational auxiliaries to ensure efficient production. Please provide us with your best quotes and specifications for the requested equipment.
