How to choose a Concrete Grinder For Home Renovation
Single head concrete grinders are low cost to hire, relatively aggressive and easy to handle, but they do leave grinding shoulders otherwise called tool marks which appear as rings when the concrete is wetted or when a sealer is applied. Larger diameter grinding wheels will leave a flatter finish with less tool marks than smaller diameter grinding wheels, however they will not grind to the bottom of depressions as easily which could leave the floor with many small areas where the floor has not been ground wet grinder. Double head concrete grinders are faster than single head grinders because they cover more area with the downside being that they are much heavier to move around and consume more electric power. These concrete grinders are mainly used for general flattening or cleaning of concrete, or they can be used for exposing the aggregate while they are usually not suitable for polished concrete.
Planetary concrete grinders leave very few tool marks because they have either three or four grinding wheels turning clockwise and these are connected to a turntable that turns anti clockwise. The four head machines have two of the heads rotating clockwise and the opposite two rotating anti clockwise as well as the turntable rotating and these have the advantage of being very smooth to operate with almost no lateral forces that would require physical effort to control. These machines are ideal to achieve polished concrete with their smooth grinding finish and the ability to easily replace the diamond grinding wheels to move through the different grit sizes.
Another type of concrete grinder is the eight wheel, flat type with four of the grinding wheels rotating clockwise and four rotating anti clockwise. These machines also produce excellent results for polished concrete or just for preparation of concrete floors for cleaning or for coatings application. They are also designed for quick and easy replacement of the grinding wheels and do not suffer from lateral forces like the three headed planetary machines or the single headed machines.
All of the above equipment can grind floors easily except for the corners and edges. The edges require an edge grinder that can place the grinding wheel against a wall and run along the wall to even the grinding up to the edge. There are walk behind concrete grinders for this purpose that have either adjustable wheel tracking axles at the rear or a grinding head that can swing to the left or right to enable the grinding wheel to run along the wall while the concrete grinder is move parallel to the wall.
The most common type of floor edger is an angle grinder with a dust shroud attached and a diamond grinding wheel underneath. These either have a cutaway section for the wheel to reach the wall edge or they have a flat seal section where the wheel protrudes slightly which has better dust control. There is also a type of dust shroud that has two flat sections for getting into the corners and a sit down style of angle grinder where the operator sits on a stool and floats the concrete grinder along the wall edge using handles located on the grinder to prevent bending. This type has the added advantage of being close enough to the floor to see if it has been ground properly.
All of this equipment requires an adequately sized vacuum dust collector connected to them to prevent airborne dust. Some concrete grinders can operate from the same power outlet as the dust collector while other grinders will require a separate circuit power outlet. Your choice of grinder will depend on the cost of hire, the size of the job, whether a smooth finish without tool marks is critical and if the edges need to be ground too. If you still don’t have a home meat grinder, ask yourself one question: why? Meat grinders are a great tool for any kitchen, and can be used for a lot of different dishes. Grinding your own meat has its benefits. Firstly, you know what you’re putting into your ground meat. Sometimes, prepackaged ground meat can come from any number of animals. Since it’s all ground up when you buy it, you can’t always be sure of the quality. Sometimes, you get beef mixed with pork or chicken. Also, it gives you a lot more options when it comes to seasoning and flavoring the meat. Simply mixing different kinds of meat will give you unique taste combinations. You can even control the amount of fat you put into the grind. You can add spices to make your ground meat taste better as you have total control over your meat.
A manual home meat grinder is a cheap way to grind your own meat. However, they can be quite hard to operate. If you have a stand mixer, you can always get a KitchenAid meat grinder attachment. This enables you to grind meat using your KitchenAid meat grinder and stand mixer.
It’s always important to take care of your meat grinders, if you want them to last you a long time. All you need to do is remember a few tips while using your grinder. Remember, if you take care of your grinder, it’ll take care of you.
It’s always important to keep all of the meat you grind cold. Warm meat tends to leak, and the fat gets too soft. This is not good for the texture of the meat. A great way to keep this from happening with warm meat is to chill the entire grinder before using it. Also, make sure that you only feed small pieces of meat into the grinder. People complain that their grinders tend to smear, but this is mostly because they are feeding big chunks of meat. This could dull the blades so it’s always best to cut them in small, bite-sized chunks first.
