AGGREGATE STOCK
AGGREGATE INLINE BUNKER (3 - 6 COMPARTMENTS)
Aggregate Inline Bunkers of concrete batching plants have up to 6 bins depending on thecapacity of the plant. Aggregate Inline bunker is designed and manufactured as perrelated DIN norms to operate under heavy working conditions for long time. There exist 4electro-pneumatically controlled discharge gates, which provide easiness and choice in thedischarge together with suitable elevation. Aggregate weighing belt conveyor of the
aggregate bunker, which has 5 kg sensitivity, manufactured to operate without anyproblem under heavy working conditions with mechanical separator, every kind of safetyprecautions, air pressure measuring device and etc. as per world conditions. Aggregate isweighed by 4 units of load cells and weighing belt conveyor has all safety switches like;sensor for break off of belt, rope controlled safety switch, emergency stop button andswitch that prevents belt slides.

AGGREGATE FEEDING
BELT CONVEYOR
Belt Conveyors, used for feeding aggregate from aggregate bunker to mixer, has a widthof 800, 1000 and 1200 mm depending on the capacity of batching plant, up to 200
inclination standard smooth surface belts are used, if the inclination is bigger than 200
then chevron type belts are adapted. To be covered with galvanized plates One side having traveling platform from ground All belt conveyor are covered by galvanized metal sheet Once the belt conveyor is stopped, the lock that prevents to returning is always
present

MIXERS
MEKA started the production of construction machines in 1987 and has focused onconcrete batching plants production for 15 years and became expert in this subject. Bythe support of its research and development department, it does not only produce newmodels but also renews and modernizes the design of current plants according totechnology and customers requests. The facts that the products of MEKA are in very
good quality, MEKA adapts the high technology to the plants and institutionaltrustworthiness of MEKA made MEKA equivalent with the European producers.
The MEKA mixers which are produced with high quality have already carried MEKA to thetop of the companies which are batching plant manufacturers. Since mixer is the mostimportant part of a concrete batching plant and the quality and strength of producingconcrete directly depends on the quality of the mixer, MEKA mixers have been used forlong time by more than 150 clients and have already proven itself in ready mix andblock making operations with deepest experience of MEKA.
Today, 0.5, 1 and 2 m3single shaft MEKA mixers are used properly not only inMEKA plants but also in plenty of different plants in Turkey and other countries.
MEKA produces 30-36 concrete batching plants in a year (which means average 3 in amonth) and the factory works with full capacity. At the moment MEKA works onexpanding the capacity of the factory.
In so many plants of MEKA which are operated, MEKA mixers are used and up to350.000 m3concrete is produced in one year. Although the production of concrete hasexceeded 400.000 m3there has not any wearing out and corrosion inside of the mixerbeen existed so far and none of internal coatings and mixer paddies of the mixer haverequired to be changed.
In addition to these, MEKA has succeeded to get CE certificate from TUV who examinesall of the parts carefully (electromagnetic, low voltage, machine safety) before standing
as surety. The most important parameter that enabled MEKA to get these certificates isthat MEKA mixers are also examined very carefully and has proved that its in very highquality and in European standards.
Mixer is the most important part of the Concrete Batching Plants, which has an effect
on the concrete mixing quality and time. Mixers used in the Concrete Batching Plants are
made by MEKA with linings made from cast Ni - Hard and/or Hardox 400/500 plates.

Twin Shaft Mixer
Mixer has synchronously operating two horizontal shafts and inner part of the mixer iscovered with easily changeable wearing plates and mixing paddles are covered with castplates that are very resistant against wearing. Automatic lubrication system of the mixerprovides required pressure of oil at the bearings. Cover of the discharge gate of themixer operates hydraulically and has a pump to manually open the gate in case of power
failure.
