What Is The Mainstream Small Batch Concrete Mixer
Apr 03, 2023
The small batch concrete mixer is a machine that mixes materials such as sand, stone, cement and water according to a certain mix ratio into uniform concrete (C15-C60) that meets the quality requirements. It is mainly composed of mixing system, feeding system, water supply system, unloading system, and electrical system. The mixing system is mainly equipped with motors, pulleys, gearboxes, gears, mixing drums, etc.
The compulsory concrete mixer is mainly based on the shearing mechanism to stir the mixture. For twin shaft concrete mixer, there are two horizontally arranged mixing shafts inside the mixing drum, each shaft is equipped with a number of mixing arms and several pairs of mixing blades are scattered at the ends of the mixing arms. Then the mixing arm and the mixing blade rotate with the main shaft to realize the mixing work of the concrete.
Twin shaft concrete mixer VS single shaft concrete mixer
1. Transmission device
The transmission device of the single shaft concrete mixer’s main engine is a chain transmission structure; while the transmission device of the two shaft mixer’s main engine is V-shaped transmission belt and gear structure. The latter design has a lower noise and has a higher safety.
2. Mixing effect
For some common types of concrete, their mixing performance is about same, but for some highly demanding concrete products such as dry concrete, the mixing effect of single shaft concrete mixer is very poor. As a whole, the mixing effect of twin shaft concrete mixer has a more even mixing effect.
3. Discharging performance
The discharge port of the single-shaft mixer equipment is difficult to control in the specific production process, and its discharge door is very easy to be stuck, and the discharge performance is very general. The two-shaft mixer effectively overcomes this problem, and its discharge performance is also very good. This is another crucial reason why the twin shaft mixer is so popular.
Advantages of twin shaft concrete mixer
1. High efficiency
For high-performance concrete, the mixing time is only 60 seconds, which is more than 20% higher than the actual efficiency of ordinary mixers.
2. Energy saving
We adopts large space and low volume utilization, making mixing easier. The blades continuously push the entire material to form a high-speed cycle, with small impact load and low energy consumption. After strict comparative tests, it can save energy by more than 15% compared with traditional mixers.
3. Strong durability
The blades of the small concrete mixer machine are made of high wear-resistant alloy and wear-resistant cast iron. The perfect stirring device improves the flow of materials and reduces the friction and impact of sand and stone on the blades. The service life can exceed 60,000 batches. The liner adopts trapezoidal design, and under the premise of maintenance and adjustment according to specifications, the service life can exceed 70,000 batches.
4. No slurry leakage
Our concrete mixer adopts multiple shaft end seals, which can effectively prevent the mortar from leaking out. At the same time, the automatic lubrication system delivers lubricating grease, and the grease pressure ensures the long-term reliability of the shaft end seals.
