Classification by operation mode
⑴ According to the operation mode, there are two types: circular operation type and continuous operation type.
The three processes of feeding, mixing and unloading of circulating operation are carried out at a certain time interval, that is, batch mixing.
The mixing quality is good because all materials are accurately weighed. This type of operation is mostly adopted.
The above three processes of continuous operation are carried out continuously in a long cylinder. Although its productivity is higher than that of circular operation, the mixing quality is poor because the mix proportion and mixing time of each material are difficult to control. Less used.
Classified by mixing method
⑵ According to the mixing method, there are two types of mixing: self dropping mixing and forced mixing.
The self dropping mixer is to place the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum lift the mixture to a certain height, and then it can be freely scattered by its own weight. In this way, it will be carried out repeatedly. How much will it cost from the charging mixer truck until it is well mixed. This mixer generally mixes plastic and semi plastic concrete.
Compulsory mixer is the mixing drum is not moving, but is forced to mix by uniformly placed blades on the rotating shaft inside the drum. The mixer has good mixing quality and high production efficiency; However, the power consumption is high and the blades wear quickly. It is generally applicable to mixing dry and hard concrete.
Classification according to device mode
⑶ There are two types of devices: fixed type and mobile type.
The fixed mixer is installed on the prepared foundation, and the whole machine cannot be moved. It has large volume and high production efficiency. It is mainly used in mixing plants or mixing plants.
The mobile mixer itself has driving wheels, and is small in size and light in weight, so it has good mobility. It is applied to small and medium-sized temporary works.
Classified by discharging method
⑷ There are two kinds of discharging methods: tipping type and non tipping type.
The tipping type relies on the tipping of the mixing drum for unloading, rather than the tipping type relies on the reversing of the mixing drum for unloading.
(5) According to the different shapes of mixing drums, there are five types: pear type, drum type, biconical type, disc vertical shaft type and circular groove horizontal shaft type. The first three are self dropping stirring; The latter two are forced mixing, which is seldom used in China.
1. The engine oil and filter element shall be replaced regularly from the feeding mixer, and the oil quality of lubricating oil of any quality level will change during operation. In order to prevent the occurrence of faults, the oil shall be replaced regularly under the operating conditions, and the oil quantity shall be moderate (usually the upper limit of the engine oil scale is better).
2. The lubricating oil of appropriate quality grade shall be used for the self feeding mixer, and SD-SF grade gasoline engine oil shall be selected for gasoline engine according to the additional equipment and operating conditions of the intake and exhaust system; For diesel engine, CB-CD diesel engine oil shall be selected according to the mechanical load, and the price of self feeding mixer truck shall not be lower than the manufacturer's rules.
3. The mixer can clean the fuel system regularly and control the generation of carbon deposits to keep the engine in good condition.
4. Maintenance of mixer truck with three filters: three filters refer to air filter, oil filter and steam oil filter. Since the mixer truck is loaded, most steam oil engines are now equipped with PCV valves (forced crankcase ventilation), but pollutants in the blowby will deposit around the PCV valves, which may block the valves. Therefore, the pollutants around the PCV valve must be removed regularly.
The self loading mixer is mainly used for concrete works and concrete mixing, also known as concrete mixer. The commercial concrete mixer adopts the popular quick assembly module type structure, high-performance imported mixer, self loading mixer manufacturer, double machine and double control computer control mode to prevent noise and dust pollution. The environmental design is a new generation of cement concrete mixing equipment, which is suitable for the specific needs of urban commercial ready mixed concrete, roads and bridges, water conservancy, airports, ports and other large-scale infrastructure construction projects.
Safety protection of mixing station:
During installation, it is strictly forbidden to tilt or deform the legs.
The embedded parts at the bottom and base of the support leg shall be welded firmly.
Good wind and lightning protection.
It has a strong impact on legs and silos.
Regularly check the cement adhesion of the dust collector and clean the bag.
The foundation must be firm and conform to the building design specifications.
