Double Horizontal Shaft Forced Concrete Mixer Working principle and Maintenance

Nowadays, under the global strategic policy of accelerating grass-roots capital construction and progress, urban areas are undergoing transformation and construction rapidly, and concrete is of irreplaceable significance in infrastructure projects, resulting in an unlimited demand for commercial concrete and other building materials. Although the production capacity of small and medium-sized forced concrete mixer can not be compared with that of large concrete mixer equipment, its function is the same, and the mixing is symmetrical, which can produce high-quality commercial concrete.

The double horizontal shaft forced concrete mixer is a kind of concrete mechanical equipment that mixes raw materials such as sand, stone, cement and water with a certain mortar mix proportion into uniform and compliant concrete. It is the most popular mechanical equipment in the mixer sales market at this stage. There are JS500, js750, JS1000, JS1500, JS2000, JS3000 and other models. It has high production efficiency, good mixing performance, simple operation, convenient disassembly and stable operation, It has the characteristics of low noise and is an excellent concrete mixing machine.

The main components of forced concrete mixer are mixing device, transmission system, frame, limit device and electrical control system. The frame structure is welded with channel steel, which is an important supporting component of mixing equipment. The main components of the mixing device are mixing drum, mixing shaft and mixing shovel. The mixing shovel is mainly installed on the mixing arm, and the transmission mechanism is composed of reducer motor and coupling. The components of oil cylinder limit device are mainly locking pin and positioning hole. The main functions of the electrical control system are start, jog, stop and timing.

Working principle: the forced concrete mixer is mainly composed of two connected circular trough mixing cylinders horizontally arranged, two mixing shaft machines rotating in the opposite direction and rotating mechanism. Several groups of mixing blades are installed on the two shafts, and the front, back, up and down are staggered with a certain space, so that the mixture can be mixed in turn in the two mixing cylinders. On the one hand, the mixture at the bottom and middle of the mixing cylinder is turned upward, On the other hand, the mixture is pushed forward and backward along the axis, so that the mixture can be stirred quickly and evenly.

Feeding system: the brake motor of the forced concrete mixer drives the steel wire rope drum to rotate according to the reducer, and the steel wire rope pulls the hopper upward. When it climbs to a certain height, the hopper enters the feeding frame, the bucket door opens automatically, and the materials are discharged into the mixing drum through the hopper.

Unloading system: there are three structures, hydraulic control, pneumatic control and manual control. The discharge door is installed at the bottom of the mixer to realize motorized discharge through air cylinder or hydraulic cylinder. A limit switch is installed on the discharge door to control the opening and closing position of the discharge door. The sealing of the discharge door can be ensured by adjusting the position of the sealing strip.

The double horizontal shaft concrete mixer mainly mixes high-strength, dry and hard concrete, which has the following three advantages:

1. The double spiral blade shaft configuration makes better use of the cylinder space, the blade mixing energy release mode is better, and the material mixing is more uniform. Therefore, the mixing time in the working process is shorter, the mixing is more uniform and the efficiency is higher;

2. It can be used in a single machine or form a simple concrete mixing plant with PLD series batching machines, which has good applicability to all kinds of large, medium and small prefabricated component plants, industrial and civil construction projects;

3. The shaft end is equipped with multiple sealing protection and wind pressure sealing protection devices to ensure the stable operation of the whole mixing device, long service time and less dust.

To prolong the service life of any equipment, it is very important to learn to maintain it. Here are some points to note:

1. Maintenance. The mixing shaft is the core of the mixer and must be filled with oil. You can see the leakage of butter in the mixer every time;

2. The parts to be replaced shall be replaced in time, and the problems found shall be repaired in time;

3. After each use, the mixer must be cleaned in time, the residual materials in the mixing shaft and mixer must be cleaned, and the fixation of the bearing and cylinder of the discharge door must be checked in time.
