What is a mixer? Well, a mixer is any machine used for mixing various ingredients. In general they are of two types; continuous and batch mixers. In continuous concrete mixers, loading of contents, mixing and unloading is a continuous process and goes on for an indefinite period of time. Where as in batch concrete mixers, loading, mixing and unloading can be done only for a definite quantity and for a definite period of time.
However the principle behind the mixing process remains the same for both continuous and batch mixers and it is more or less like a long-screw. In other words mixing of the ingredients is done by means of blades or paddles which are mounted on revolving shafts. Based on the structure, concrete mixers are broadly classified into three types:
1. Gravity
2. Rotatory
3. Paddle
However, when it comes to purchasing or renting a concrete mixer, performance and requirement will be taken into consideration. For instance, if you are looking for a mixer which should be operated for an indefinite period of time for mixing huge quantities then the continuous mixer is the best option. In case if the mixing quantity if less or for a small period of time then batch mixer will serve the purpose.
To better understand the differences between a batch and continuous mixer let us compare D-10 batch and D-25 continuous mixer. Both D-10 and D-25 can mix all types of pre-blended mortar products but D-10 can mix products up to 2.25 CuFt batches where as D-25 can mix products in any amount.
Similarly capacity of the D-10 batch mixer is 4.5CuFt whereas the capacity of D-25 is up to 80 Cu Ft per hour. Dimensions of D-10 batch mixer are 45″H x 36″L x 29″W and that of D-25 are 74″ x 30″ x 47″. So, the major differences between D-10 and D-25 mixers are only in terms of capacity, dimensions and the operational hours. Apart from that both D-10 and D-25 share common advantages such as:
1. Variable pump output
2. User friendly
3. Can be operated via remote
4. Compact and easy-to-use
5. Almost maintenance free due to incorporation of high quality components
6. Versatile applications etc.
So, the choice of concrete mixer depends on your business requirements. If you have big projects on hand, then opt for continuous mixer whereas if you are looking for a small project with minimal mixing operation then opt for batch mixer.
