Soil mixing plant (GSU) - this is specialized stationary or mobile equipment designed for mechanical mixing of various components (soil, cement, ash, water, lime and other additives) in order to obtain a homogeneous mixture used in road construction, soil strengthening, foundation construction and preparation of construction sites.

The initial inert materials, loaded into the hoppers of the inert conveyor dispenser, equipped with vibrators, are dosed by means of feeder conveyors with a frequency converter in the required volume onto a horizontally inclined belt conveyor. The conveyor transports materials directly to the continuous mixer.

The cement loaded into the silo is fed into the intermediate hopper of the cement dosing unit via a screw conveyor. From the dosing unit, cement is dosed in the required volume using a paddle feeder equipped with a frequency converter, then by a screw conveyor into a continuous mixer. The dosing unit itself also acts as a dispenser for Big Bags.

Water pumped into a water tank or taken from another reservoir is supplied in the required volume to a continuous mixer using a pump equipped with a frequency converter, adjusted according to flow meter readings.

All of the above components are continuously mixed in the mixer in the required proportions. The finished mixture is fed onto a horizontally inclined belt conveyor, along which it is unloaded either directly into a truck or into a ready-mix bunker. To operate the pneumatic system of the ready-mix bunker, the installation includes a compressor. The absence of a ready-mix bunker can cause difficulty in operating the installation: if the transport required to load the ready-mix is ​​delayed, then the operation of the entire installation will have to be interrupted.

The installation is controlled from the operator’s cabin using the SCADA system pre-installed on the computer. With its help, the operator adjusts the operating parameters of individual units of the installation, receives up-to-date information about the serviceability of this or that equipment, saves and loads recipes, generates reports based on the results of the shift, and implements other software functionality.

The main characteristic of a soil mixing plant is its productivity. This indicator, in addition to the reliability of the operation of individual components and assemblies, is directly influenced by the volume and power of the mixer engine, and indirectly by the number and capacity of inert material bins, cement silos, and water tanks. That is, the high productivity of the gas treatment plant depends not only on the theoretical ability of the equipment to produce a large volume of the mixture, but also on the availability on the site of a sufficient supply of materials and additives used in the technological processes.
