The raw materials that need to be used in the water-stabilized mixing plant are cement, fly ash, graded gravel, etc. The process operation of the production materials of the water stabilized mixing plant is relatively simple, and only a certain amount of raw materials needs to be put into the mixer in a certain order to stir and mix. These materials can be mixed with a certain amount of water, and the appropriate amount of water can play a role in lubricating the material, reducing the friction of the material, and promoting the mixing and stirring of the material. At the same time, water can also help cement to disperse and dissolve better, and fully mix with various raw materials to form a homogeneous water-stabilized mixture.
The equipment of the water stabilized mixing plant mainly includes mixer, batching machine, material conveying system, cement tank and control system. The equipment of the water stabilized mixing plant has a microcomputer system of batching storage, automatic drop compensation and manual, semi-automatic and automatic control. The mixer model of each mixing plant is different, and the motor power configured will be differentIt takes about 35-380,000 yuan to build a 700-meter water stabilization station**May vary by region and by configuration and material. Like the WBZ-700 model of the water stabilized mixing station, its productivity is 700t h, the mixing host is equipped with two 75kW motors, the weight of the whole machine is 52000kg, generally equipped with 4 bin batching machine, can also be decided according to the type of material used, the material bin generally has raw material bin, batching bin and finished product silo. The aggregate diameter of the water stabilized mixing station is 60mm, the speed of the mixer is 117r min, the total power is 186kw, and the water metering accuracy is within the range.
The sand generally used in the hydrostable mixing plant is coarse sand, medium sand and fine sand, and their roles in the water-stabilized material are also different. Fine sand is mainly used to fill the voids in cement mortar and improve the compactness and strength of stabilized soilMedium sand mainly improves the compressive strength of stabilized soil, it is able to provide better support and hold shape;Coarse sand can improve the stability of the stabilized soil, it can provide better grip, making the stabilized soil more firm and stable. When choosing sand and gravel, we should also pay attention to the requirements of cleanliness, hardness and diameter of sand and gravel.
Although the viscosity and stability of the material of the water stabilized mixing plant are not as strong as the material of the concrete batching plant, the water content and mix ratio of the water stabilized mixture need to be controlled according to the engineering requirements to ensure that its quality and performance meet the standards. The water stabilized mixing plant can be fully automatic control, semi-automatic or manual control, the operation is simple and convenient, the weighing system is relatively simple, there is no need for complex parameter settings, the control panel has a human-machine interface, which can concisely and vividly measure and control the on-site process flow of the mixing station, and understand the operation of the entire mixing station.
