Wheat, corn, rice, mung beans, soybeans, etc. are very familiar food types in our daily lives. In general, in order to provide consumers with safe, high-quality food and related products, food is often required first before entering the market for sale. The quality inspection and testing indicators include gluten number, quality, grain viscosity, wheat falling value, near-infrared composition, and other indicators. In these inspection items, hammer mills are used for sample preparation, and only through hammer-type cyclone mills. Only the comminuted samples that meet the requirements can be used for the determination of gluten number, quality, grain viscosity, wheat fall value, and near-infrared composition.
Hammer-type cyclone mills have a very high frequency of use in grain inspections. With the prolonged use of the hammer mills, some parts of the instrument will also cause losses. In order to ensure the crushing effect, some of the parts that are relatively easy to wear are Such as the screen, impeller, belt, etc. may need to be replaced in time, so for the hammer cyclone mill common replacement parts, the following to do a brief introduction.
1. Belt replacement method The linkage of the various parts of the Hammer cyclone mill is driven by the belt, so the belt loss will directly affect the crushing effect of the hammer cyclone mill. When the belt is replaced, the first is to remove the top cover and the rear Cover, and then release and remove the fixed plate between the bottom of the housing and the motor, it is best to remove the lower seat together with the motor from the housing and replace it.
2. Replacement method of sieves Hammer-type cyclone mill sieves can ensure that the selected comminuted sample meets the relevant measurement requirements. Therefore, if there is a loss of the sieve, it needs to be replaced immediately. The replacement method of the sieve is as follows: The upper cover of the grinding chamber is removed and turned on the table; the second step is to loosen the fastening screws at the two ends of the sieve and then pull out and insert the sieve to complete the replacement of the sieve; the third step is to re-tighten the two screws , And ensure that the grinding belt is close to the peripheral wall of the grinding chamber to prevent the pressing piece from colliding with the impeller.
3. Impeller replacement method The impeller is also a very important part of the hammer type cyclone mill, and the method of changing the impeller is not complicated and it can be completed in three steps. The first step is to remove the upper cover of the grinding chamber; the second step is used internally. The hex wrench loosens the impeller fixing screw; in the third step, pull out the impeller carefully, replace the new impeller, and tighten the screw.
The above is the description of the replacement method of the common accessories of the hammer type cyclone mill. To improve the service life of these parts of the hammer type cyclone mill and to reduce the degree of wear and tear, staff members are required to do maintenance and maintenance of the equipment in peacetime, and properly maintain and Deal with the excellent performance of the instrument.
The rotating element in the friction pair of disc brake is a metal disc working on the end face, called the Brake Disc. Friction elements clamp brake discs from both sides to produce braking. The fixed elements have a variety of structural forms, generally can be divided into disc brake clamp disc type and overall type of two types
