1. How to choose a right concrete mixer ?

Face to the various concrete mixers in the market, purchasers often feel confused. Here Bona show you how to choose a right concrete mixer as follow:

First, choose concrete mixer according to project amount and period.
If project amount is big and project period is long, use large&medium stationary concrete mixer or concrete batching plant. On the contrary, use
small&medium mobile concrete mixer.

Second, choose concrete mixer according to concrete types.
If you want to mix plastic concrete or semi-plastic concrete, use self-loading concrete mixer. If you want to mix high intensity concrete, dry concrete
or light concrete, use forced concrete mixer.

Third, choose concrete mixer according to concrete composition properties and consistency.
If concrete consistency is small and aggregate size is big, use self-loading concrete mixer with large capacity. On the contrary, use forced concrete mixer
or wimble reverse discharging concrete mixer with small&medium capacity.

2.how to operate a concrete mixer machine?
First, push the function switch to auto place, press open button on controller, then whole operation process will be a automatic form.
Second, concrete mixer machine will be stop automatically in the end of operation process. If you need halfway down, press the stop button and restart.
Third, after pressing open button, time, slow down, add sand, speed up, stop and run indicator lights will show on the screen.

5. What should be noted when cleaning concrete mixer?

No Details No Success. Concrete mixer cleaning is a very important process for concrete mixer normal operation. To keep correct cleaning process

should pay more attention to the following notices.
First, maintain specified-in-detail items at fixed period, such as cleaning, lubricating and refueling.
Second, before start-up of each shift, check if various motion parts are normal. After shutdown, pour water and stones into concrete mixing tube, cleaning

for ten to 15 minutes, then clear out them. Before the operator step into concrete mixing tube to clean, turn off power source and unload fuse cutout, paying

particular attention to lock the switch box.
Third, to remove concrete left in mixing tube, no sledgehammer, chisel only.
Forth,in the freezing winter, use water to clean concrete mixing drum, put a net pump, tank and pipe with water horse against frost damage

9. What’s the difference between concrete pump mounted on a truck and placed on a trailer?
A concrete mixer pump is a machine used for transferring liquid concreteby pumping. There are two types of concrete pumps.
The first type of concrete pump is attached to a truck. It is known as a trailer-mounted boom concrete pump because it uses aremote-controlled articulating

robotic arm (called a boom) to place concrete with pinpoint accuracy. Boom pumps are used on most of the larger construction projects as they are capable

of pumping at very high volumes and because of the labour saving nature of the placing boom. They are a revolutionary alternative to truck-mounted concrete

pumps.The second main type of concrete pump is either mounted on a truck and known as a truck-mounted concrete pump or placed on a trailer, and it is

commonly referred to as a line pump or trailer-mounted concrete pump. This pump requires steel or flexibleconcrete placing hoses to be manually attached

to the outlet of the machine. Those hoses are linked together and lead to wherever the concrete needs to be placed. Line pumps normally pump concrete at

lower volumes than boom pumps and are used for smaller volume concrete placing applications such as swimming pools, sidewalks, and single family home

concrete slabs and most ground slabs.There are also skid mounted and rail mounted concrete pumps, but these are uncommon and only used on specialized

job sites such as mines and tunnels.
