Better mixing by concrete mixer trucks requires consideration from aspects such as mixing time, mixing speed, mixing sequence, mixing capacity, and mixer structure. Here are detailed answers:
Mixing time: The mixing time of the mixer truck should be determined based on the type and mix ratio of concrete. Generally speaking, the mixing time should be between 1-3 minutes, and too long or too short a time can affect the quality of concrete.
Mixing speed: The mixing speed of a concrete mixer truck should be determined based on the type and mix ratio of concrete. Generally speaking, the mixing speed should be between 2-6 revolutions per minute. Too fast or too slow speed can affect the quality of concrete.
Mixing sequence: The mixing sequence of the mixer truck should first mix the water and powder evenly, then add the aggregate for mixing, and then mix for a period of time to ensure the quality of the concrete.
Mixing capacity: The mixing capacity of the mixer truck should be determined based on the actual load capacity of the vehicle to avoid uneven mixing or degradation of concrete quality due to overloading.
Mixer structure: The mixer structure of the concrete mixer truck should be reasonably designed, and the mixing blades should be evenly distributed with appropriate shapes and angles to ensure uniform mixing of concrete.
In addition, the water volume in the water tank of the concrete mixer truck should always be kept full for emergency use. After shutdown in winter, the water in the water tank, water pump, water pipe, and mixing drum should be drained completely, and parked in a sunny place without accumulated water to avoid freezing and damaging the machinery.
When inspecting and repairing the hydraulic transmission part of the mixer truck, the engine and hydraulic pump should be operated without pressure. When adjusting the clearance, stroke, and pressure of each part of the concrete mixer truck, it should be checked and approved by a full-time safety officer; When replacing machine parts, it must be signed by the director or the manager in charge, otherwise the relevant personnel will be held responsible after any problems occur.
In short, only by fully considering and carefully grasping these aspects can the mixing quality and stability of the concrete mixer truck be ensured. Come to our website if you have any needs http://www.skar-bnat.com consulting service
