Buying Used Concrete Mixers

The cement mixers are quite helpful in completing your building job much faster. If you spend a lot of time mixing the cement then your task may not be successful. Using an industrial mixer is a perfect solution. Some of these mixers deliver excellent productivity. At the same time, budget is an important factor for any work. Nowadays, people do not buy everything they need but prefer to rent them. Another option of saving money is going for used items. Therefore, you can surely buy used cement mixers for yourself. However, lots of people may not want to buy second hand mixers as this type of construction equipments are exposed to a lot of wear and tear. The used equipments are perfect for the workers and companies that work on bigger projects. They can be used in the initial stages of your work or if you have a limited budget.

Your purpose

There are certain things that you should keep in mind while purchasing a second hand mixers. If the right factors are not considered then you might waste a large amount of your hard earned money and buy a mixer which would not be helpful for you at all. Most importantly, you should know the main purpose of this equipment. This is mixing cement with water, sand and gravel. A revolving drum is used in most of these concrete mixers. The components are mixed inside this drum for creating the product that is needed. While buying a cement mixer that has been used you should make sure that the machine is in good condition and would deliver you with the desired results. The mixer should work efficiently for your construction work. Used cement mixers that are in good condition will surely work with the required efficiency.

Type of mixer

You must decide the type of cement mixer that you want while buying it. Using the right type of mixer is important for performing the job efficiently as well as effectively. You will find lots of options but the two basic categories of this equipment are portable mixer and stationary mixer.

· The portable mixer is perfectly mobile and you will be able to carry it easily. Therefore, they can be taken to the construction site conveniently. There are several advantages of such mobile cement mixers.

· The other type of concrete mixer is immobile. These mixers should be kept fixed in a particular location and are known as stationary mixers. Such machines are generally used to pre-cast buildings. In most of the cases, these cement mixers are used in projects in the remote locations. These mixers are generally capable of producing large quantity of concrete on a consistent basis.

Finding a company

You can look for different companies that sell used cement mixers. Find out a firm that provides all the information about the products that they sell. It is important to ensure that the mixer that you purchase is a durable one. Buy from a place that is near to your work site or home as these machines are usually bulky and heavy duty.

What to Keep in Mind When Purchasing Laboratory Roller Mixers

Laboratory rollers and mixers are instruments that are specially designed to create homogenous mixtures of two or more substances. Generally, one will find roller mixers in laboratories that conduct research on areas such as biotechnology, life sciences, and waste water treatment. However, laboratory mixers are also extensively used in other industries. They are found in labs of companies related to pharmaceuticals, food and beverage, electronics, and cosmetics. Suffice to say, laboratory roller mixers are an important product that is must have for any lab.

Basic Design and Features

Laboratory roller mixers consist of motor driven rollers that create a rocking and rolling action. They also have a paddle or a blade that supports the mixing process. This helps to create gentle movement that allows the substances in specimen bottles to amalgamate. Some of the general features that you will find in roller mixers are:

Continuous and quiet operation
Light weight and portable
Industrial grade manufacturing
Easy to clean and decontaminate

Some laboratory instrument manufacturers also design their roller mixers with features like tilting from side to side or moving up and down to ensure proper mixing.

Considerations for Purchasing Laboratory Mixers

A basic understanding of the design and features of roller mixers can be helpful in choosing one for a laboratory. However, making a decision simply based on the above information would not be wise. Like everything else related to research and development, laboratory equipment needs to be chosen by considering a few important aspects.

Choosing the Right Machine: Many a time, lab equipment sourcing personnel get confused between roller mixers and shakers. While they may seem similar, these are two different products and so are their applications.

Shakers are products that use vibrations from the platforms n which the specimen bottles are placed, thus creating the mixture. As mentioned earlier, rollers use a paddle to mix the substances together. In terms of chemical processing, these two methods will produce different results. One has to see the end result and then choose the right type of product.

Handling Liquid Viscosity: This is an important point that needs to be considered. Usually, laboratory mixers are used to mix blood samples and immiscible liquids. Every liquid will be different in terms of volume, weight, and mixing capability. The roller mixer needs to have the right settings to effectively mix two different liquids.

Roller Mixer Capacity: It is important to choose a laboratory mixer with the right number of specimen holders. This will allow you to meet your work demands in a timely fashion. Generally, one will find four to six rollers in one product. However, there are roller mixers that can mix an entire rack of bottles.

Tube Size Handling: Laboratories use different types of tubes and bottles in various sizes. Glass and plastic Bijoux and Universals tubes and bottles are generally used in the rolling mixing process. The product should have the versatility to handle all these types of bottles.

Speed and Variability: While roller mixers can be used on a continuous basis, every project has deadlines that need to be met. Once the previous points have been satisfied, the speed of the mixing process has to be taken into consideration. It should not only be able to mix the liquids at a particular speed, it should also have a feature that allows for speed variability. High speed mixing can also result in a change in temperature, so that should also be considered.

The best way to choose the right mixer product is to have a complete understanding of a laboratory’s requirements. With that information in hand, it will be extremely easy to find roller mixer that will meet all the above mentioned features.
