厂拌冷再生工作原理
移动式厂拌冷再生设备 – 它是如何工作的？
KMA 240(i) 整台设备安装在平板车上，装有独立的供电装置。移动式理念使得该设备能够快速就位于不同的施工场地，组装毫不费力。轮式装载机将各种松散的原材料，通过振动隔栅加入到配料斗内。料仓和/或罐车，为厂拌设备提供水泥、乳化沥青或泡沫沥青等粘结剂。为了计量精确，微机控制系统监测各种原材料与粘结剂的添加量。高质量厂拌冷再生材料的均匀拌合，由双轴搅拌锅完成。最后，由摆动式输料皮带输送再生材料，即使长半挂车也能轻松装满。
One-of-a-kind mobility and flexibility
Simple, intuitive operation
Maximum productivity
Effective mixing process
Optimal material flow with intelligent functions
Precise binding agent addition
Recipe for success for hard-wearing road surfaces
The KMA 240(i) cold recycling mixing plant produces cold mix that can be paved immediately for a wide variety of construction projects, such as cement-treated base (CTB) layers for freeways. Due to the particularly generous, continuous addition of cement, enormous daily outputs can be achieved with maximum precision.
In addition to CTB and RCC (roller-compacted concrete), cold mix can be produced that is stabilized with bitumen emulsion or foamed bitumen (BSM).
The road surfaces produced from these high-quality cold mixes perform superbly due to their excellent bearing capacity, resistance to deformation, and long service life.
ECO-friendly technology
The highly mobile cold recycling mixing plant can be easily transported from site to site and quickly set up in the near vicinity. This saves time, truck capacity, and is also extremely environmentally friendly, making it possible to achieve up to 60% fewer CO2 emissions thanks to cold processing, a 90% reduction in transport volumes, and up to 50% lower total costs compared to conventional construction methods – in other words, an investment that pays off in every respect!
Compact transport dimensions
The well-engineered design allows the compact system to be easily and safely “packed up” onto a flatbed truck trailer and transported to the next site, saving both time and money. All you need to do is swivel in the discharge conveyor and operator’s cabin, move the cement charging auger to the transport position, and then hitch up the plant. A common truck is completely sufficient for transporting the plant as all of its connectors are standardized.
The compact transport dimensions and low overall weight of the KMA 240(i) comply with international traffic regulations, eliminating the time-consuming process of applying for special permits in most locations.
Mix production at a rate of over 240 t / h
At first glance the KMA 240(i) appears comparatively small. But when it comes to performance, the exact opposite is true – the compact machine packs a punch. Powered by a heavy-duty diesel engine, it can produce high-quality mix at an astonishing rate of 240 t / h. This mixing capacity even far exceeds that of many stationary large-scale plants.
But it doesn’t just come down to performance, a continuous supply of materials to the job site is also crucial.
This is guaranteed by the field-poven loading system of the KMA 240(i). The discharge conveyor features wide swing angles that make it possible to evenly fill semitailer trucks.
With a capacity of 240 t / h, the machine produces a full truckload of 20 tons of mix every five minutes This means that, for example, an enormous section of a cement-treated or bituminous bound base layer 4.0 m wide, 15 cm thick, and 1.4 km long can be paved every day.
Optimal material flow with intelligent functions.
The main components of the plant – the material hopper, dosing units, and twin-shaft continuous mixer – mesh together perfectly, ensuring that the binding agents are added to the raw material weighed in the mixer precisely and simultaneously. The end result is a mix quality that precisely matches the required recipe.
Gravimetric cement dosing via innovative double trough system
The innovative double trough system features two independent, state-of-the-art weighing units. This allows cement to be dosed gravimetrically from one trough while the other trough is simultaneously being filled with more cement and precisely weighed. The alternating dosing process is carried out with the utmost precision and without interrupting the addition of binding agent.
