// Unit_01 — Storage
Storage Hopper
Storage Hopper is the equipment employed for storing solidifying agent raw materials. A set of equipment usually includes one or two storage bins to load different solidifying agent raw materials respectively. The solidifying agent raw materials are automatically transported to the control center through the conveying pipeline from the lower funnel for configuration.
The shape of the storage bin can be vertical or horizontal. The common specifications are 50 ton and 80 ton Hopper — if the customer has other size requirements, it can be customized. The bin body and support are made of high-quality steel, with stable structure, firm welding and long service life.
Material level alarm
When the internal solidified materials (cement, fly ash, lime, slag micro powder, etc.) are higher or lower than a certain value, it will automatically alarm and stop the system.

// Unit_02 — Control
Control Centre
The control center is a container type equipment controlled by computer full-automatic PLC (programmable logic controller) to configure and mix the solidifying agent according to a certain proportion, also transmitting the solidifying agent to the power mixer.
The device is made of quality steel, with a long square style design and installed with a door. You can enter the control center to check the working status of the control panel and mixer. The shell helps protect the internal device from the influence of the environment, improve the mixing efficiency and prolong the service life.
Component
Function
Controller
Core of the control centre — controls the mixing and transportation of solidifying agent
Upper stirrer
Raw material and water enter at the preset ratio to mix and stir into a mixture
Lower stirrer
Further mixing to form a solidifying agent with good solidification effect
Water tank
Supplies water for configuring the solidifying agent
Two operation modes
In automatic mode, you can start and stop with one button by inputting various values in the control panel, such as solidifying agent ratio, pressure and conveying rate — the operation is simple. In manual mode, values can be adjusted at any time according to the solidification situation, which has greater flexibility and is conducive to better solidification effect.
How the controller works
The controller works according to the preset solidifying agent ratio, pressure and conveying rate. The material ratio is obtained according to the pre-test results, and the conveying rate is selected according to the size of the excavator and the rotating speed, temperature and volume of the power mixer.
Pressure setting
Selected according to the depth of the power mixer. Generally, the deeper the power mixer reaches, the greater the back pressure will be, the greater the transmission pressure setting. Refer to the user instructions and VANROCK's specialists for details.
In the construction process
After the controller is started with one key, raw material and water enter the upper stirrer through the transmission pipeline at the preset ratio to mix and stir. The mixture enters the lower stirrer for further mixing, and the finished solidifying agent is transmitted to the front power mixer through the hose pressure and acts on the sludge.
Real-time monitoring
A monitoring system tracks the actual weight of solidifying agent raw materials and water, the weight of the upper and lower stirrers, the switching state of each pump and the mixing countdown in real time.
Always in control
The engineer can know the working status and adjust it at any time to ensure the normal operation of the equipment.
