Optimize and design draw ratio of mixing barrel body and inverted Ωstructure to ensure strength and rigidity. Four spindle bearing points and sealing points adopt digital control borer to ensure reliability.	Imported brand lubricating system adds oil automatically to four spindle sealing points to ensure spindle end seal. Each lubricating point adds oil timingly by manual shifting three-way valve’s handle.	Adopt imported brand rectagular planetary speed reducer special for concrete mixing, which has such advantages as smooth transmission, handsome and compact structure, over-loading protection, etc.
Discharging door adopts top brand hydraulic unit to drive and has adjustable opening. It’s equipped with manual pump.	Water and additives measuring and putting-in. Water and additives are separately pumped into storage tank inside the tower and imported pneumatic butterfly valve is adopted to control with speedy movement and accurate measuring. After measuring, inject them through high-pressure pump and clean totally. Additive measuring barrel is made of stainless steel.	Main tower dust-removal
Belt conveyor environmental protection All powder materials must be in total closed state during transport, measuring, and putting-in. In main tower are set imported dust-exhauster and wind blower to use negative pressure to absorb dust produced in aggregate collecting case, main engine, and powder material measuring bucket, etc. Slanting belt conveyor is equipped with outer package and charge chute, while main tower is totally closed to reducer pollution from dust and noise and powder tank is equipped with imported dust-remover.	Low-position container	High-position container
Various quantities and volumes of distributing plant/containers can be equipped according to various demands. Below are aggregate measuring bucket and output belt conveyor. Loader or belt conveyor are used to supply materials. Distributing plant/containers can be designed into ground container, low-position container, high-position container or inner container of mixing tower. Sand container is equipped with imported vibrator and water ration measuring meter can be selected and installed.
Transportation measures	Available as needed ≤ 19 ° C-belt, ≤ 24 ° C word profile belt, a belt or dip Ribs on the struggle to upgrade materials; Ring belt from the professional manufacturers do not vulcanized joints, making pre-tensioning; using mallets automatic tensioning; Self-cleaning device configuration.	Powder transportation needs can be configured according to different volume and quantity of powder cans, the allocation of import of flour and cans Annex spiral conveyor, Powder guarantee the smooth transportation; From powder cans to the main building can be used for gas distribution or pink cans directly overhead ’to send gas measurement; Powder Metering struggle can configure 1 -4; Measuring imports bucket equipped with pneumatic vibrator and disc valve, seal tightly and dump do, Express.
