① weight, installation and removal time consuming; ② central trough is generally made 6 ~ 15mm of steel plate, subjected to
Larger impact deformation, repair more difficult; ③ poor corrosion resistance; ④ poor wear resistance; ⑤ materials and in
Bolted Type Cement
Silo friction coefficient, power scraper conveyor most consumed in the friction material and the central groove on
Resulting in excessive energy consumption, increased investment.
Ultra-high molecular weight polyethylene is manufactured using scraper conveyor plate, steel plate to resolve the problems,
Get plastic scraper conveyor. For small scraper conveyor can be modified to manufacture ultra high molecular weight polyethylene
Made scraper conveyor. For the above walking Shearer large concrete batching
plant , plastic composite method to be used
With ultra-high molecular weight polyethylene lined with large scraper conveyor to improve wear resistance, long life
, Reduce the friction coefficient, thereby reducing power consumption and reduce the traction drive system requirements, which for large
Scraper conveyor has a huge significance. This product is developed by the Shandong University of Technology, can be used in coal mines, chemical mines,
Metal mines and power plants and other materials transportation.

Concrete batching mixing device
Because of its mechanization, high degree of automation,Therefore, productivity is high, and to ensure the quality of concrete and cement savings, Commonly used in concrete construction volume, long duration, site concentration of large, medium Type of water, electricity, Wheel Loader and other projects. With the development of municipal construction, mining Stir with a focus on providing commercial concrete mixing machine has a great location, And thus rapid development, and to promote concrete pumping construction, real Now stirring, transport, pouring mechanical joint operation to create the conditions.
Batching and mixing difference: mixing smaller capacity, structural Easy installation, can be composed of container transfer sites suitable for construction works are Field; mixing large volume, high productivity, only as a stationary mixing Devices for large hydraulic works or production of large commercial concrete supply.

Major component of concrete mixing station
Concrete mixing plant concrete mixing plant mainly by the mixing console, the material called Cement silo, material handling systems, material storage system and control system, etc. 5 Large systems and other ancillary facilities components. Because bone building aggregate measurement and station Material measure, a decrease of four intermediate links, and cement mixing machine blanking meter Volume, saving the measurement time, thus greatly improving the efficiency of production, the same type Number of cases, the mixing ratio of production efficiency production efficiency three mixing station One half.
The use of cement paste mixer
(A) Keep work area should be cleaned thoroughly after each use Clear stir Mixed leaves and stir the pot, outside the residual mortar, and sweeping machines scattered and splash Mortar and Bolted Type Cement Silo, wipe dry after, put on guard, to prevent dust.
(2) The machine has no external filling hole. Pay worm gear box, gear paid and Bearings and other moving parts on a quarterly basis plus molybdenum disulfide grease once, when refueling Open each bearing cap, bearing between the guide rails and columns, lifting bodies Should always drip oil lubrication, maintenance once a year, all the machine cleaning And add oil and grease.
(3) In case of metal crash the machine running noise, you should first check the mixing Leaves a gap between the pot and stir correctly.
(4) use of stirring the pot, you should gently, not free collision to Free deformation caused by stirring the pot.
(5) When replacing a new pot or concrete batching plant should be adjusted according to the aforementioned method Whole gap.
(6) should always check the electrical insulation at 20 ℃ ± 5 ℃ Relative Humidity Degree of 50% to 70% of the cold insulation resistance ≥ 5MΩ

Two-speed motor
Two-speed motor (1) through the coupling (2) the power to the transmission case (10) within the The worm (3) and then the worm wheel (6), and a pair of gears (7) and (9) to the spindle (8) and deceleration. Asphalt Mixing Plant shaft seat (12) synchronous rotation, so that fixed Eccentric seat (12) on the stirring blades (16) revolves. While stirring leaf through Mixing blade shaft (14) the upper end of the planetary gear (13) around a fixed internal gear (11) complete the rotation movement. Two-speed motor cement mixing machine programmable automatic completion time Into a slow - stop - fast forward work program requirements. Stirring the pot (17) and slide Plate (18) rotates with eccentric locking groove.
Cement mixer should be noted that in winter park
Winter park, the water tank and the water supply system, not a surplus of water.
Discharge chute, together with the need to lengthen the chute, the specific work requirements of the position to decide.
Loaded concrete forward, if you want to reverse, we must make the joystick forward completely stopped, and Screw Conveyor the joystick. Prohibited during the joystick forward so inverted.
According to road uphill different mix concrete in a barrel shape see photos. Drivers should be based on a reasonable charge to walk the road surface slope situation, avoid spreading material on the road, polluting the environment. This book chapter II.2 nominal volume is 120 slump stir when approved, concrete slump exceeding the value uphill, loading volume should be reduced appropriately.
Mixing tube high center of gravity and concrete batching plant Right (car look), this bias when mixing tube full rotation will increase, so the car must be very careful when cornering. Especially the car to turn left, you should be more careful not to exceed the speed of the mixing tube 3r/min. Mixer turning diameter and the maximum stable speed relationship see Figure II. It should also reduce the speed of the road is not flat.
Prohibited mixer full speed sharp turns.
Non-operating personnel, prohibited actions.
After work, it must be the vehicle and into the hopper, the mixing tube inside and outside the discharge chute and so clean. The door is locked, turn the locking handle, lock handle securely and servo throttle handle.

Cement mixer system
Mixing system
Mixing device consists of Concrete mixing plant and auxiliary support components. Mixing tube Loading of the concrete container, the blade is rotated along the spiral direction of the concrete Movement, constantly upgrading and turning process by mixing and stirring. In Feeding and transport process, the mixing tube is transferred, transported to the inside concrete along the blade Move, the material, the mixing tube reversal, concrete discharged outward along the blade. Stirring blades are the core components of the device, can cause damage or severe wear Concrete mixing uneven. In addition, if the angle of the blade design is unreasonable, But also the concrete appear segregation.
cleaning system
The main function of cleaning system is to clean steel cement silo, is sometimes used for transportation purposes In the dry material mixing drum. Cleaning system is also a cooling effect on the hydraulic system.
Cooling system
Cooling system using high temperature cycle oil for hydraulic pumps, hydraulic motors at work too Process heat generated through the heat sink and fan dissipate, avoid heat build Into the hydraulic system damage and malfunction.
Cement mixer for mixing different volumes, different manufacturers and different chassis Will lead to the use of different mixer accessories and layouts. But it works both Are the same.
