Different Types Of Concrete Batching Plants

JHT TEAM PROVIDES CUSTOMIZED SERVICES FOR DIFFERENT CLIENTS

Wet, Dry & Half-Wet Options

WET

Most of our products are designed for wet  production. While it is the most popular type in our area Dry and Half-Wet applications are well demanded in other parts of the world.

DRY

Main chassis of some models can be modified for additional dry leg to provide the flexibility of producing Wet & Dry mixes simultaneously.

HALF-WET

A useful application to get the best of both worlds. During Half-Wet operation aggregates bypass the mixer and only sand with other materials are being mixed in the mixer. While this application reduces the overall capacity it drastically increases the lifetime of the mixer wearing linings.

Components & Options
Steel frames to minimize the foundation work for main elements and silos

Foundation work is adding a significant cost to the first investment. Especially for temporary installations and constant relocations this investment can be avoided with our steel frames/foundations. Steel foundations can be offered for cement silos, main chassis and other elements of the batch plants. They reduce the installation time and ground work.

Steel ramp walls for aggregate bins

Steel ramp wall is another application that reduces the foundation work and the cost for ground work. Steel ramp wall is fixed to a slab foundation and eliminates the need of building high walls for aggregate bin feeding ramp.

Heating Options - Principles of Operation

During cold winter times in order to get a desired  temperature aggregates and water must be heated up. A steam/hot water generator produces a certain amount of steam and hot water at the same time. After the aggregates have been loaded, electrically controlled covers must be closed.As steam passes through the aggregate bin heat exchangers (open type - with steam injection or closed type - without steam injection) aggregates heat up. According to the outside temperature the heat up process time may vary.
After aggregates are warmed up batch process can be started. "Sandwich" paneling keeps the interior warm during operation and for a long period of time after the system has been shut down. After cold start up first several batches may not be warmed up enough. In order to get a better temperature control for the operator, temperature and moisture sensors can be installed.

Steam/Hot water generators

A steam or hot water generator of adequate capacity supplies steam or hot water to the system. Diesel/Natural Gas/Fuel oil/LPG or mixed burner types can be installed. Containerized type, easy maintenance, high quality, high efficiency.
- Steam (closed/open cycle), hot water or hot air suppliers for aggregate bins
- Cladding with sandwich panels or corrugated steel panels
- Covers over the aggregate bins

Cooling Options Principles of Operation

During hot summer times, in order to get a desired temperature water must be cooled down. A chiller system is continuously circulating the water in a tank. Cooled water is being pumped to the weighing scales.

In extreme hot conditions cooling the water may not be enough. In this case ice must be used. MEKA offers ice weighing hoppers and ice screw conveyors to implements them into the batching process. Ice making machines must be purchased separately.

Components & Options

Radial and Shuttle-Conveyor aggregate pre-feeding systems

Aggregate feeding systems allow easier operation and eliminate the construction of big loading ramps.
Shuttle-Conveyor Feeding

This option is normally more suitable for loading the aggregate bins with 6+ compartments and on sites with different elevations where radial conveyor can not be used. A fixed aggregate feeding bin and conveyor transfer the aggregates to the shuttle-conveyor that can rotate to both sides. Shuttle-conveyor is moving on rails on the top of the main aggregate bin and its position is controlled by the switches.Both feeding systems can either be operated manually from the panel or with a wireless control from the loader.

Radial Feeding

Conveyor position change is being done with the help of a chassis with wheels. Up to 5 bins can be fed with one radial conveyor. Feeding bin stays fixed while the conveyor moves from one side to another.

Components & Options
Cement transfer system (BIG-BAG or standard)

In some countries and in some distant locations cement is not always available in truck deliveries. Users have to opt between 50kg standard bags or 1-2 ton Big-Bags. Filling these into the silo requires a special blower or screw conveyor system.

Compressor based system

The most convenient and fast cement transfer system. 8 m³ tank is filled from standard or big-bags and the cement or micro silica is being blown into the silo with the help of a separate compressor.

Screw conveyor based system

Depending on the height of the silo a cheaper model with screw conveyor provides constant filling into the silos. Standard or big-bags load a small bin that is connected with the silo with the help of a screw conveyor.

Components & Options
High Pressure Mixer Washout System

70 bar high pressure mixer washout system can be offered upon request.

Filter over the mixer for dust suppression

A dust collecting filter can be installed over the mixer upon request. While our standard By-pass system that is connecting the mixer, cement weighing hopper and aggregate holding hopper together provides a significant dust reduction and prevents vacuum inside the cement weigh hopper, some countries require filter over the mixer as a standard.

Components & Options
Air cannons for aggregate bins

In certain situations, it is not possible to completely discharge the aggregate bin and remove all the material completely without the workers getting inside it.Air cannons allow a high-pressure air blast inside the aggregate bin which allows complete discharge of the aggregate bin.
