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.

Concrete mixer Handling Precautions



Concrete mixer Handling Precautions:
1. concrete mixer should be set at a flat position, with square wooden paving around the axle of the tire put high overhead, avoid walking in motion occurs.

2. concrete mixers secondary leakage protection should be implemented after the power is turned on before work must be carefully examined by the turn that the empty test qualified before use. Commissioning tests should be mixed with drum speed is appropriate, under normal circumstances, the proportion of empty vehicle speed (after charging) slightly faster 2 to 3 revolutions, such as a difference of more, should be adjusted to move the wheel and drive wheel ratio.

3. the direction of rotation of mixing drum should be consistent with direction of the arrow, as inconsistent with reality, should be corrected electrical wiring.

4. Check the drive clutch and brake is flexible and reliable, wire rope for damage, pulley track is good, there is accessibility and various parts of the lubrication and other surrounding circumstances.

5.boot, always pay attention to the various components of the concrete mixer operation is normal. Shutdown, always check whether a clincher concrete mixer blades, whether or loose screws have knocked.

6. when the concrete mixing is completed or is expected to be more than expected 1 stop outside the net, use stones and water poured into the shaking cylinder, power rotation, to stick to the barrel of the mortar discharged completely clean after flushing. You may not have water in the barrel, in order to avoid the barrel and leaf rust. It should also clean up outside the mixing tube fouling, the mechanical clean intact.

7. after work and do not stop, it should wind up its power, and lock the switch box to ensure safety.

The basic rules of concrete mixer



Commodity concrete mixing machine basic rules:
1. Concrete mixing machine should be placed in a solid place, with a stand or feet creel stable. Allowed to replace the tire support.
2. before the start mixing machine should check the controller and the parts is good. It shall be a foreign body in the drum.
3. mixing machine when the hopper is raised, strictly prohibited by or stays in the hopper. After the work is completed shall be fixed mixing hopper.
4. the mixing machine running, the tool inserted into the inner cylinder is strictly prohibited.
5. site maintenance, should be fixed mixing hopper off the power. When entering the mixing machine drum, outside should someone custody.

Twin shaft concrete mixer performance characteristics and operating procedures



Concrete twin-shaft  mixer is mainly used for mixing of various powder materials. We can produce all kinds of powder mixing materials. Its aggregate may be wet fly ash, calcium carbide sludge, gypsum, gravel, slag and so on. It is mainly used in the past of supporting host a variety of standard bricks, sand-lime brick production line, one of the important equipment is autoclaved fly ash bricks, sand-lime brick production process of. Now a major project in the concrete mixing station also put it as supporting the host.
Structure Features
Concrete twin-shaft compulsory mixer is mainly composed of chassis, screw shaft assembly, drives, piping, cover, chain cover and other components.
1
Check before use
Transmission to press the switch, and then close the knife, to check whether the operation is flexible. Vibrators, roller operation, dial feed stick is functioning properly. Rope is wound on the reel; lift the refuse station, etc. are normal. If found fault, notify electromechanical team process. After the deal, before use.
2
Once the material can not be too much, according to the ratio of materials, pay attention to water-cement ratio. Stir once mixing time of not less than one minute, normal marinated concrete, it should be very thick porridge-like.
3
Fixed hand boot, drivers should be familiar with the role of the principle of each operating system, found fault immediately stop inspection.
4
Most appliances should love, cables to protect against damage.
5
Mixers should level up, people can not stand under the hopper mixer, to prevent the next funnel trounced wounding.
6
Temporary stop rail, it should regularly (every twenty minutes), start the mixer, to prevent solidification of concrete or concrete poured into the drum, drum rinse.
7
After filling Tongjiao End stop, should be promptly mortar and machine outer drum water rinse clean. Next class clean up once the feed hopper to feed a predetermined position when material falls political decentralization, and coated with a layer of oil on the outside until the next use.
