Hammer crushers are specialized devices for grinding any materials. They greatly facilitate a person’s life, as they relieve him of the need to do it manually.
The advantages of crushers and their varieties
The presented devices have some important advantages, these are:
- simple design that allows you to quickly find spare parts in case of breakdown of the unit;
- hammer crushers can quickly grind materials such as wood, coal, stone, grain and others;
- very good performance;
- Ease of use;
- security;
- high quality work.
It should be noted that these devices are often equipped with a variety of filters, which not only regulate the size of the fractions of the material, but also protect the components of the device from clogging. In addition, you have the opportunity to adjust the size of the output material.
There is one drawback of such a machine: it cannot work with those materials that contain more than 15% moisture in their composition.
As for the varieties of these devices, then hammer crushers are single-shaft or two-rotor. In this case, the hammers can be fixed rigidly or using hinges. And they are located in one or more rows. Regarding the direction of rotation of the shaft, the devices should be divided into reversible and non-reversible.
The mechanism of operation and features of the use of the unit
The principle of operation of the unit is quite simple: the hammers that are inside the case rotate with one or more shafts. At the same time, they beat the material there and grind it. The crushed substance passes through certain filters that regulate the size of its fractions.
The shaft rotates with an electric motor through a coupling and a belt drive. Hammer crushers are very compact, so they can be used in domestic conditions. With the help of these devices it is possible to produce fine, medium and large crushing. Before work, it is advisable to determine the quality of the material to be crushed. The type of unit that will need to be used depends on this. Hammers that are installed on the device have a useful feature: if they wear out, they can be used as a work surface.
Most often at home, a hammer crusher for grain is used.
How to choose the right device?
In order for the grinding to be of high quality, and the apparatus to work efficiently, it must be correctly selected. First of all, pay attention to what kind of material you will crumble. It depends on how many hammers in the device should be present, as well as how they will be attached. For example, if the raw material is solid, then the shock elements must be screwed tight enough. For grinding grain, you can use the articulation of hammers.
You also need to consider the dimensions of the unit, its orientation relative to the base and performance. These parameters depend on how often the device will be used, and how much raw material it should process. Naturally, the size of the fractions that the crusher can give out, as well as the possibility of regulating their size, is also taken into account here.
Pay attention to the build quality and materials of which the unit is made. When choosing, try to give preference to well-known manufacturers with a good reputation. As for orientation in space, it is better if a vertical hammer mill is purchased. She is more comfortable.
As for the cost of the device, then it all depends on your capabilities.
