HZS180 concrete mixing plant

1, excellent performance
The double horizontal shaft forced mixer has strong mixing ability, uniform mixing quality and high productivity. For dry hard, semi-dry hard, plastic and various proportions of concrete mixing effect is good. The lubrication system and spindle transmission system can be imported with a full set of original packaging, and the hydraulic door opening mechanism can adjust the opening of the discharge door as required. The mixing shaft of the mixing machine adopts anti-adhesion technology to effectively prevent cement from caking on the shaft. The shaft end seal adopts a unique multiple sealing structure to effectively prevent mortar leakage and ensure the continuous operation of the entire mixing system. Cleaning system adopts high pressure water pump automatic control and manual control,are located directly above the mixing spindle, which improves the mixing efficiency, increases the water mist to reduce dust pollution and effectively removes cement agglomerates.

2, environmental performance

All powdery materials are carried out in a closed state from loading, batching, metering, feeding to mixing and discharging. The dust discharge pipes of mixer cover, cement metering bin and fly ash metering bin are all connected with the dust remover, and the aggregate filling port is provided with dust blocking plate to reduce dust emission. The fully enclosed mixing main building and belt conveyor structure reduce the pollution of dust and noise to the environment. The use of negative pressure dust removal and special fiber filter cloth, so that the dust generated during feeding into the dust collector without spreading to the surrounding, and the collected dust can be easily recycled and reused, effectively protecting the environment. Users can also choose to import dust removal system.

3, reliable performance

stirring blade adopts unique high chromium and high manganese alloy wear-resistant material, and the shaft end support and sealing form adopts unique multiple seals, which improves the reliability of the main engine. For places that are often impacted and vulnerable, such as unloading hopper and transition hopper, wear-resistant steel plate is used to strengthen the inside. The joint of the ring belt is vulcanized and bonded, and the service life of the right to use is 3 times longer than that of ordinary steel riveting.
Good mixing performance: the maintenance and repair parts of the whole set of equipment are equipped with platforms or repair ladders, which are convenient for inspection and repair operations. The main engine cleaning is equipped with two sets of pump punching and manual operation devices. The platform floor structure and the fully enclosed structure of the aggregate belt conveyor ensure that all operations can be carried out normally. The belt conveyor adopts a closed form, and the overflow outlet is arranged at the lower part, which can effectively prevent sand and gravel from being scattered everywhere. The belt conveyor adopts heavy vertical tension structure, which eliminates the adjustment work in the production process.

4. Operating System

The whole machine adopts computer control, which can be automatically controlled or manually operated, and the operation is simple and convenient. The dynamic panel displays the operation of each component of the mixing station (building), and can store various data of the mixing station (building), print various report materials as required, and store more than 30000 formulas. The control room is spacious and bright, beautiful and generous, and equipped with air conditioning, which can ensure the durability of electrical components, stable and reliable performance. The control system adopts the form of dual-machine dual-control, data sharing between the control machine and the management machine, when the control machine fails, it can be converted to the management machine to work, to a certain extent, to ensure the continuous normal operation of the system. Monitoring cameras can be set in key components such as the host discharge port and the batching station.

5. Introduction of Electronic Control System
The electronic control system adopts the form of dual-machine dual-control, that is, the system consists of two high-performance industrial computers, one as the main control production system, and the other as the management and monitoring system (also as the backup machine of the main control production machine), using a dedicated batching control instrument. As the main controller system, it has manual and automatic functions. Industrial computer through external sampling, after calculation, comparison, processing, output control of external drive components, so as to truly achieve the mixing station (floor) computer control. The management and monitoring computer system serves as the backup system of the entire electronic control system. In case of problems with the main computer, the user can choose the backup machine system to work, so as to ensure the normal operation of the machine at any time and not affect your production. The system has the functions of printing statistical production daily report, monthly report, online detection and monitoring. At the same time, it has a fault diagnosis help system to guide users to repair. The manual button system on the console panel can complete the automatic control of ingredients, unloading and concrete manual control functions.

6, metering performance
Whether it is the weighing of aggregate, powder or water agent, its weighing, control and signal conversion elements can be imported components, high-precision sensors, imported microcomputer control, and each scale is individually weighed (or cumulative weighing) to ensure accurate measurement and stable working performance.

7, Weighing System

Cement, fly ash and other powders are transported by the screw machine to the weighing hopper for measurement. Water and liquid admixtures are controlled by pneumatic butterfly valves and ball valves, with good sealing and fast action to ensure weighing accuracy. Water into the mixer through the booster pump pressurized spray, so that the water faster and mixed with the mixture, and more thorough cleaning.

8, mixing the main building

adopts H-beam as the main beam, the structure is stable and firm, and the anti-vibration force is strong. The cables and trachea in the building are arranged with special wiring troughs, which are neat and beautiful and conducive to the protection of cables. The outer seal is made of profiled color steel plates, which is beautiful and generous. Thermal insulation layer can be added as required to adapt to the cold weather in the north.

9. Conveying device

may be provided with three to five bone bins as required, with a separate aggregate weighing hopper and aggregate discharging belt at the bottom of the aggregate bin. Use a loader or belt conveyor to feed the bone silo. The silo may be designed as a steel structure. The lower part of the silo can be equipped with a low moisture content measuring instrument. The aggregate lifting inclined belt conveyor is responsible for sending the aggregate to the transition storage bin. The inclined belt is tensioned by heavy hammer, which is reliable in operation, and the conveying inclination angle is ≤ 18 °. It can also be fed by man-shaped or groove-shaped belt conveyor or bucket elevator to reduce the occupied area.
