Process flow
(1) raw materials: sand, cement, fly ash, slag, gypsum, shale, most of industrial waste can be used as block raw materials, which improves a lot on environment.
(2), Measuring, batching and casting section
Slurry, cement agents, gypsum and aluminum go into high-speed stirring mixer after automatic measuring respectively, and then bubbles inside green body will be sorted out by vibration rods. The whole system is full-automatically controlled by PLC to guarantee the high efficiency and precision of procedure running.
(3)Static curing and Cutting
Stable and still curing can avoid damage to internal structure when the gas is and expanding inside the green block.
High efficient and fluent cutting machine and table tilt machine are the key parts to the hexahedral cutting.
(4) Autoclaving and Final Product Process
Green body gets final strength and performance via autoclaving.
Dongyue’s newly developed separating and packing system can not only promote qualification rate but also solve the difficulty in separating blocks and wall panels at the same time.
Service process
Preliminary investigation: local raw material condition, market demand and the potential for long-term growth are the factors which shall be considered.
Whole plant planning: engineers’ selection of the equipment configuration and the technological layout are the basis of the optimum scheme.
Speedy delivery: excellent processing and manufacturing capabilities and reputable quality assurance system ensure the clients the fastest investment returns.
Installation and debugging: Dongyue installation group has domestic first-class commissioning engineer team and serve 400 clients around the world.
Training: the training starts from equipment installation and debugging and ends to the point where the operator is able to run production on his own;
it also aims to help establish the only domestic training base of the model line at the same time.
