Concrete mixing station on the role of air compressor



     Usually concrete mixing station must be equipped with air compressor is , what concrete mixing station on the air compressor is the role of it?
     Pressure compressor provides air , this part of the air used to open the valve cement , fly ash and other tanks , open mixing console discharge doors. Simply provide power . In addition , there are some mixing console discharge door instead of using the air but the hydraulic open. Use air has several advantages: 1 , raw materials, unlike the hydraulic system needs to replace the hydraulic oil ; 2 , easy maintenance ; 3 , compared with hydraulic quick action .

Standard set of concrete mixing station equipment is made up of what



Concrete mixing station consists of material feed storage systems, material weighing system, material handling system, mixing system, powder storage systems, powder conveying systems, powder metering systems, water and additive metering systems and control systems and other five major systems and other ancillary facilities components.
Mixer stirring their way into forced mixing and self-loading mixing. Compulsory mixer is mixing station at home and abroad mainstream use, it can be stirred liquidity, semi-rigid and rigid and other dry concrete. Since the fall mixing console main stirring fluidity concrete, rarely used in the mixing station.
Compulsory mixer according to the spindle structure is divided into a planetary mixer, single horizontal shaft mixer and twin-shaft mixer. The integrated use of performance especially in the twin-shaft compulsory mixer is best.
Material weighing system is affecting the quality of concrete mixing station concrete and concrete production cost of key components, mainly divided into aggregate weighing, weighing powder and liquid weighing three parts. Under normal circumstances, 20 cubic meters per hour or less mixing station superposition weighing methods, namely aggregates (sand, stone) with a scale, a scale with cement and fly ash, water and liquid additive were weighed and then put into the water, said liquid additive pre-mixed infighting. In more than 50 cubic meters per hour, mixing station, said the use of various materials weighing independent manner, all have adopted electronic weighing scales and computer control. Aggregate weighing accuracy of ± 2%, cement, powder, water and admixtures weighing accuracy reached ± 1%.

The advantages of the mobile station



Mobile mixing plant is relatively flexible concrete production equipment, some sites due to the duration of short-term, establishment is also a waste of money trouble, so small mobile batching plant to become mainstream, then what is the mobile mixing plants? What are the characteristics of mobile mixing plant is it?
The advantages of the mobile station:
1. The compact design in a single trailer unit concentrated most parts of the mixing station;
2. The mode of operation humane, stable and reliable, stable operation in a variety of harsh environments;
3. imported twin-shaft compulsory mixer, continuous operation, stir, stirring motion powerful, fast;
4. The form of the whole station via the trailer can be quickly transported to the construction site and on-site assembly is completed;
5. Before the factory pre-commissioning is completed without debugging to construction;
6. The high degree of automation, mobile and flexible, easy to operate and stable.

JS concrete mixer matters need to pay attention when debugging



Mixing machine, a shaft with blades rotating in the cylinder or tank, mixing the various raw materials, making it a mixture or a suitable consistency of machines. There are compulsory mixing machine, single horizontal shaft mixing machine, twin-shaft mixing machine. When mixing machine debugging, you should pay attention the following points.
1, to check the lubrication of the gear box and various lubricants adequacy is good.
2. Check the power supply voltage: Rated voltage is 380 volts, the error is ± 10%.
3. Check the motor and electrical components wiring is solid, reliable power distribution box housing must be grounded. Power distribution box neutral must find N terminal block, all lines should be properly resettled, while working to prevent accidents caused by crushing hit.
4, start stirring motor, two axle direction of rotation should be consistent with signs indicating directions, such as the wrong direction, the power wiring should be changed
5, boot volume field motor lifting hopper, hopper raised to unloading position, should automatically stop, Doumen automatically opens.
6, start unloading mechanism, the discharge door opening and closing should be accurate place. Start the pump to draw water, water supply systems should operate normally.
7, according to the desired ratio of concrete to determine the amount of water, and adjusted to the appropriate water supply time relay time. Start stirring motor running.
8, close the discharge gate, adding the desired mix within the hopper, lifting hopper.
9, stirring 25-35 seconds, start unloading discharge door.
10, in the above commissioning process, if found to be normal, you should immediately stop inspection, troubleshooting, and then test again, you know normal. The new machine running the liner after use, and elsewhere to deal with bolts and nuts all day, checking the tightening. Parts of transmission lubrication grease lubrication.

Drum mixer using eight Precautions



Start ago
First ,before starting the device first checks whether the rotating portion of the barrel scratching phenomenon, if scratching, should be timely adjusted.
Second, drum mixer after injection of oil can only be used at the discharge worm and sliding bearings should also be injected into the oil.
Third,Should start within a timely manner before the third clean barrel miscellaneous materials, the cylinder spacing device locking, and then start the machine, as in the direction of rotation after starting discovered not meet the requirements, should be promptly cut off the power, arbitrary two wires reversed phase, and then restart.
Using
The fourth will be loaded concrete mixture inside the cylinder, close the cylinder cover, adjust the timing of the relay according to the mixing time
The fifth pressing the start button, the spindle will be driven stirring shovel operation, to automatically stop after a set time.
Sixth unloading the first stop, then the position will be expected to be limited by the handle is released, then rotate the hand wheel, driven by the worm wheel cylinder is rotated to facilitate the discharge location, stops, and then start the machine before running the spindle effluent, row material until a clean stop spindle running, rotating the hand wheel so that the material cylinder is reset.
After using
Seventh cleaning cartridge, the water to run into the barrel of the spindle inside the barrel clean residual material or sand can be cleaned.
After eighth cleanup equipment if not a long time, should be treated in transmission parts coated with oil, placed in ventilated and dry place.
The correct use of the drum-type mixer in order to bring more benefits to the user, although the device is not what valuable equipment, but if we make the appropriate equipment maintenance, operating according to the following rules case, make our equipment in the hands of users bring substantial benefits for the user.
