Although concrete mixer has an easy cleaning, but it is particular and different from simple water wanshing. Mainly, the cleaning of mixers can include two steps. First of all, you should wash the inside of concrete mixer.

Namely, you should clean the mixing drum. Instead of water only, small stone and water should be put into mixing drum together. After about 10 minutes mixing, you can put the water and small stone out of the cement mixer.

If you have to enter the mixing drum, you must cut off the power, remove fuse and make switch lock closed. Next, you can begin to clean the outside of concrete mixer. It is different from the inside cleaning, you can rinse the concrete mixer with water simply.

But remember to cut off the power first. Besides, you should dry off the outside of mixers or the mixer can rust.

      How to choose a proper concrete mixer

      With the development of society, construction industry also makes rapid progress. And concrete mixers play a significant role in construction field, which stimulates the emergence of various cement mixer.

      With a great number of concrete mixer in market, it is not easy to choose a proper mixer. And this article will list some factors which you should take into consideration when you plan to buy a concrete mixer.

      how to chhoose a proper concrete mixer

      The first thing you need to consider is your budget. And the budget not only covers the price of concrete mixer but also should take energy cost and part replacement cost into consideration.

      Then, you should think about the usage of concrete mixer. You want to use this mixer for road, bridge, dam project or civil construction project? When ink over this question, you definitely take the aggregate kinds, maximum aggregate size, concrete kinds, such as dry hard concrete, plastic concrete, flowing concrete and so on, and discharging capacity.

      For example, the JS series concrete mixers are a good choice for industrial projects.  All these factors can help you narrow the choice and find a proper concrete mixer.

      Besides, you should consider something about concrete mixer itself. Firstly, you should know the quality of machine. It will be very upset if you get a mixer with bad quality.

      Then you can think of the power type according to your demands. The electric concrete mixes are widely used due to the less energy cost and non-pollution. While you’d better choose a diesel concrete mixer if you want to use a mixer in an electricity-starved area.

      Meanwhile, you should take the overall dimension of concrete mixer into consideration, because you need a proper place with enough space to place the mixer. What’s more, it is a good choice to put automatic level into consideration.

      Definitely, discharging type, mixing capacity, power    are also the factors needing considering.

      Last but not least, you should find a reliable concrete mixer manufacturer or supplier. That is to say, you have to know if the manufacturer of supplier has a good reputation, good equipment, great testing method, and excellent after-sale service system.

      Then you should compare the price and quality of mixers from different manufacturers or suppliers. Only when you consider these factors well can you find a concrete mixer with reasonable price and high quality.

        Simple Classification of Concrete Mixers

        What is concrete mixer? What’s the main category? Concrete mixer is a professional concrete making machine, which puts cement, water, various aggregates in a certain proportion together, then mixes them evenly.

        There are various concrete mixers in market, and it is not easy for people to know concrete mixers well. So this article will make a detail classification of concrete mixers, which can help people to know concrete mixers well and even help people to find the proper concrete mixer.

        1. Concrete mixer can be divided into periodic concrete mixer and continuous concrete mixer. Periodic concrete mixer is a concrete making machine which works in a circle of charging, mixing, discharging while continuous concrete mixer can make charging, mixing and discharging continuously and uniformly.

        And periotic concrete mixer is widely used in construction project due to its compact structure and easy control of mixing ratio and quality. Instead of construction project, continuous concrete mixer is a proper choice of road, bridge and dam projects according to its continuous work mode which leads to a high productivity.

        2. Concrete mixer can be divided into self- falling concrete mixer and compulsory cement mixer due to the mixing principle. When self-concrete mixer works, the mixing barrel can rotate around its axis.

        And the blades fixed in mixing barrel can raise aggregate to a certain height, then makes them fall down freely. Self- falling concrete mixer is characteristic of simple structure, little wear, certain adaptability to aggregate size and easy maintaining.

        However, the mixing is forced by aggregate’s gravity, which limits mixing speed and capacity nad leads to a low efficiency. Therefore, self-loading concrete mixer is used to mix plastic concrete.

        While compulsory concrete mixer is a machine with strong power, in which aggregated are mixed by rotating blades. Compulsory concrete mixer has high mixing quality and high working efficiency, which makes it quit suitable to stir dry hard concrete and light weight aggregate.

        But it has a strict limit of aggregate size and the aggregate with big size may cause blockage.

        3. Concrete mixer can be divided into stationary concrete mixer and mobile concrete mixer according to the device mode. Stationary concrete mixer, also called fixed concrete mixer, is fixed on a prepared shelf.

        With large size and high productivity, stationary concrete mixer are widely used in concrete mixing plant. While mobile concrete mixer is equipped with wheel, which ensures mixer move flexibly.

        Meanwhile, mobile concrete mixer is characteristic of small size, light weight, good mobility, so it is a good choice for temporary small and medium construction project.

        4. According to discharging mode, cement mixer can be divided into tilting concrete mixer and non-tilting concrete mixer. For tilting concrete mixer, the discharging can be finished when the mixing barrel is turned over to a certain height.

        While the rotation axis of mixing barrel is fixed when non-tilting concrete mixer begins to discharge. Besides, non-tilting concrete mixer have two discharging mode of reversal discharging and discharging by discharging chute.

        5. Concrete mixer can also be divided into electric concrete mixer and diesel concrete mixer according to the power type. Electric cement mixer, equipped with electromotor, is characteristic of reliable working, easy operation, less investment, common use.

        While diesel cement mixer is quite suitable for electricity-starved area. Compared with electric concrete mixer, diesel cement mixer has little complex operation and maintaining.

        With the development of modern technology, some advanced mixers with new power appear, such as gas powered concrete mixer, hydraulic concrete mixer, which has a less energy consumption and less cost.

        6. With the mixing capacity, concrete mixer can be divided into large concrete mixer (mixing capacity: 1000-3000L), medium concrete (mixer mixing capacity: 300-500L), small concrete mixer (50- 250L). Users can choose the most proper one according to their demands.
