What are the characteristic properties of commercial concrete mixing plants?
1. Excellent environmental protection performance All powder materials, from loading, batching, measuring, filling to mixing and discharging are carried out in an airtight condition.
The dust discharge pipes of the mixer lid, cement metering bin and fly ash metering bin are connected to the dust collector and the dust barrier is installed at the aggregate filling port, thus reducing dust emissions.
The fully enclosed mixing main building and belt conveyor structure greatly reduces the environmental pollution caused by dust and sound.
The use of negative pressure dust removal and special fibre filter cloth enables the dust generated during feeding to enter the dust collector completely without spreading to the surrounding area, while the collected dust can be easily recycled and reused, effectively protecting the environment.
Users can also choose to import the dust removal system.
2.Excellent mixing performance Double horizontal shaft forced mixer has strong mixing capacity, uniform mixing quality and high productivity.
It is effective in mixing dry, semi-dry, plastic and various proportions of concrete.
The lubrication system and the spindle drive system are all imported, and the hydraulic door opening mechanism can adjust the opening of the discharge door according to the needs.
The main mixer shaft adopts anti-adhesion technology to effectively prevent the cement from caking on the shaft. The shaft end seal adopts a unique multi-seal structure to effectively prevent the sand slurry from leaking and ensure the continuous and long-lasting operation of the whole mixing system.
The cleaning system is automatically and manually controlled by a high pressure water pump. The water outlet holes are located directly above the mixing spindle to improve the mixing efficiency, increase the water mist to reduce dust pollution and effectively remove cement caking.
3. High reliability
The mixing blades are made of unique high-chromium and high-manganese alloy wear-resistant material, and the shaft end support and sealing form adopt unique multiple seals, which greatly improves the reliability of the main machine.
The wear-resistant steel plate is used to reinforce the inside of the often impacted and easily damaged parts, such as the discharge hopper and the transition hopper; the vulcanised bonding of the ring belt joints increases the service life of the machine by 3 times compared with the ordinary steel riveting.
The station building type structure and the fully enclosed structure of the aggregate belt conveyor ensure that all operations can be carried out rain or shine.
The belt conveyor in closed form with an overflow outlet at the lower part can effectively prevent and sand and gravel from scattering around.
The belt conveyor has a heavy-drop tensioning structure, which eliminates the need for adjustment during production.
4. Excellent control system
The whole machine is controlled by computer, which can be controlled automatically or manually, so it is easy and convenient to operate.
The dynamic panel displays the operation of the various parts of the mixing plant (building) and can store various data of the mixing plant (building) and print various reports as required, storing more than 30,000 recipes.
The control room is spacious, bright, beautiful and equipped with air conditioning, which ensures durable electrical components and stable and reliable performance.
The control system adopts the unique double machine and double control form of the national office, the data is shared between the control machine and the management machine, and the control machine can be converted to the management machine when it fails, which can guarantee the continuous normal operation of the system to a large extent.
Monitoring cameras can be set up at key components such as the host unloading port and the batching station.
5. Introduction of the electric control system The electric control system is in the form of double machines and double controls, i.e. the system is composed of two high performance industrial computers, one as the main control production system and the other as the management and monitoring system (also as a backup of the main control production machine), with special dosage control instruments.
As the main control system, it has manual and automatic functions.
The industrial computer, through external sampling, calculates, compares and processes the output to control the external drive elements, thus truly realising the computer control of the mixing plant (building).
