The BIS 100 grain cleaning separator is one of the best brands of devices that are currently used to clean grain from unnecessary substances.
general description
After the grain has been collected, there is a need to clean the collected raw materials. The purpose of this operation is to separate crops from unnecessary impurities. Most often, the procedure is carried out in several stages. There are three factors that affect the grain cleaning process. The first is the type of processed raw materials, the second is the composition, and the third factor is the properties of impurities.
To date, many different cleaning methods are known. Sieve separation was one of these, for which the BIS 100 separator is intended. It is worth noting that this method can be used both for processing small varieties of grain crops and for large ones. This became possible due to the fact that during such processing the properties of raw materials are taken into account: ferromagnetic and aerodynamic.
Performance characteristics
Among the technical characteristics of the BIS 100 separator, the following can be distinguished:
- the technical productivity of the machine reaches 100 t / h, provided that the processed raw material is wheat, whose moisture content is not more than 15%, and weediness is 3%;
- the cleaning efficiency of separable weed impurities is at least 40%;
- the radius of the circular vibrations of the sieve for the BIS 100 separator is 9 mm, + - another 2 mm;
- the amount of air required to perform operations such as aspiration or pneumatic separation is 8500 m 3 / h;
- the aerodynamic drag of this machine is not more than 350 Pa;
- the dimensions of this unit in length, width and height are 2600, 2520, 1510 mm, respectively.
Here it is worth adding that there is also the A1 BIS 12 brand, which is produced from the factory in a complete set with horizontal cyclones, as well as with lock gates. But A1 BIS 100 separators do not have such devices in their configuration.
Separator sieve body
There are several basic parts that make up the separator base. Such elements include a sieve body, which is suspended from the frame. It is attached to this part with the help of elastic suspensions. Another main element is the unit, which includes two pneumatic separating channels. All other components of this unit are part of the above parts.
The sieve body of the BIS 100 separator includes two sections that operate parallel to each other. Also in each of these sections there are two more tiers of retractable sieve frames. If we consider the device of model A1 BIS 100, then there the tier is a two-lattice frame that is connected during its installation in the body using hooking devices. As these hook parts are corners and trims. Further, it is worth noting that each sieve frame is divided into cells using longitudinal and transverse bars. Each cell has its own personal rubber ball, the diameter of which is 11 mm, and it is designed to clean the sieves from particles stuck inside it.
Device design
Mesh fordons are attached to the lower planes of the same sieve frames. The frames themselves, which are already fitted in sections, are inserted between the sides of the body, following the guide angles.
Since during the lowering and stopping of the machine strokes of the BIS 100 separator A1 frame against the machine body are possible, the lower ties of the rack are equipped with attached stops having rubber shock absorber rings. This device also has trays that are designed to output large and small impurities. In order to separate small impurities from the grain culture, pneumoseparating channels are used. In the assembly of the separator A1 BIS 100 there are two pneumatic separating channels. Raw materials for processing enters each channel separately from the corresponding section of the sieve body.
Components
This unit also has a sowing sieve, from which the raw material is fed into the feed box. After falling into this compartment, the grain is transferred to the vibrating tray. This element is suspended from the walls of the air separation channel by rubber suspensions and springs. The object constantly makes oscillatory movements in the horizontal plane from the electrovibrator.
The air separation channel inside consists of a movable wall. This part is very important, since the accuracy with which the machine can remove light impurities from the grain will depend on its position. In order to ensure the movement of this object inside the channel, the unit has handles. To make it more convenient and faster to adjust the air supply to the air separation channel, it is necessary to change the position of the throttle valve. It can be ensured by turning a special handle.
Technological process
Given the characteristics of the separator BIS 100 and its components, the technological process in this machine is as follows.
The grain that needs to be cleaned is fed into two sections of the sieve body through two parallel flows. The separation of each flow of raw materials into two streams is carried out using two distributors that are included in the separator equipment and are installed on its receiving pipes. In other words, four streams of grain are fed into the separator. Two streams of raw materials are supplied to each of the sections of the unit. The following description of the principle of operation of this device will be considered on the example of one separation channel, since the second operates in a completely identical way.
The principle of the channel
If we talk about the design of the separator model A1 BIS 100, then the principle of operation is as follows. From the receiving pipe, the mixture of grain is fed to a sorting sieve. In the sieve, the raw materials are distributed evenly over its entire area. This operation is carried out due to the operation of the valve. There is also a part called an apron that reduces the risk that good grain will end up in the waste department. The removal of large impurities from the separator is carried out using a tray, but the raw materials with small impurities pass further, getting on the sowing sieve. The removal of small impurities is carried out on the bottom of the body, where they also fall into the tray, which displays them from the device.
After the grain on the sieves has been cleaned of small and large impurities, it enters the feed box of the air separating valve, as well as to the vibrating tray. It is worth noting that the height of the grain level, which is located in the feed box, can be adjusted using springs. Further, under the influence of a large mass of crops, a gap appears between the vibratory tray and the wall of the feed box. Through this gap, the grain enters the zone of influence of the air flow. The separator model works with different types of agricultural crops.
Finally
The price of the BIS 100 separator ranges from 400 to 900-950 thousand rubles. However, it is worth paying attention to the fact that this device manifests itself best when working in conjunction with other units. This is also indicated by the reviews of those people who have already purchased this machine. Some owners argued that it is best to use BIS 100 only for secondary grain processing, and for the primary use a different model. There are people who claim that the cost of a set of units, which includes the BIS 100 separator, will cost 5-10 million rubles.
