Compost Screener Selection Tips

The selection of screening machinery and equipment is a troublesome process, but in fact, as long as we have a good understanding in advance, it is not difficult to select the drum screening machine suitable for NPK fertilizer production process.

As long as you have a good understanding of your own material characteristics, dry and wet degree, screening accuracy and material proportion, you can master a good method. This is a brief introduction to the selection of this screening machine in purchasing.

Take chemical fertilizer as an example, there are many kinds of chemical fertilizer, which have different material characteristics, such as particle size, powder size, viscosity, non viscosity, etc., so there are many kinds of vibrating screen. For example, the large particle urea screen is not only a fine screening machine, but also can be called plane reciprocating screen, fertilizer grading screen, etc. Generally, the most commonly used fertilizer screening machines are fine screen, drum screen, linear vibrating screen, etc

Rotary drum screening machine is mainly used for screening and grading of chemical large granule urea, powder material or pellet feed in feed factory. It can also be used for primary clean raw materials in feed factories and grading intermediate products after secondary crushing in large and medium-sized feed factories. In addition, in the process of fertilizer manufacturing, the particles treated by NPK fertilizer granulator can be selected accurately.

In addition, the rotary drum screening machine can also be widely used for screening and grading raw materials and finished products in grain, food, chemical, sugar, mining, paper and other industries.

How to screen unqualified fertilizers out?

Drum filter is used to separate finished products and returned materials. It is commonly used in fertilizer manufacturing industry. It is a kind of fertilizer production equipment. The drum screen works stably and adopts integrated screen, which is easy to maintain and replace. When operating drum machine, pay attention to the following matters.

Fertilizer drum screening machine for quality fertilizer production

1. Before starting the screening machine, check whether the main shaft of the shaker is flexible, whether the screening machine is lubricated, and whether the connecting parts such as bolts are loose. The screening machine with dust removal device should start the dust removal device first, and then start the screening machine. After normal operation, the screen surface of the drum screen can be evenly distributed.

2. During the operation of the roller projector, the staff should regularly check the wear of the equipment, check whether the local wear of the screen surface leads to leakage, whether the screen surface is too large or deformed due to the screen hole wear, which affects the accuracy of particle classification and fertilizer screening efficiency. If the screen is damaged, it must be stopped for repair. Parts and components of over worn screen should be replaced in time.

3. When the drum screen is running, the bearing of the filter should be lubricated correctly. In normal operation, grease should be injected once a week with an oil gun. Every two months or so, remove the bearing cover to clean the bearing and re insert the grease. At the same time, check the temperature of the bearing carefully. The bearing temperature shall not exceed 40 ° C and the maximum value shall not exceed 60 ° C.

4. Pay attention to whether there is noise when the drum screen is running. Check the screen frame for vibration. If the screen frame shakes, check the support spring for damage.

5. In the parts of the screening machine, the screen surface is easy to wear. Drive belts, springs and bearings should also be replaced regularly. Keep the parts clean and tight before assembling the new screen. The screening machine parts should be maintained according to the service conditions. Generally, no repair is required within two years. The worn parts can be replaced. Go to https://compostturnermachine.com/ for more types of machine in quality organic fertilizer production.
