Muyang Chaole Series SWFL 110B/C Ultra-fine Pulverizer

SWFL B/C series vertical ultra-fine pulverizer is a new type of equipment for large-, medium- and small-sized feed mills to process various coarse ground materials after preliminary cleaning, magnetic separation and mixing, such as corn, sorghum, rice, wheat, soybean meal, fish and shrimp, so as to obtain the materials in superfine particle size as required. It is especially suitable for fine grinding or ultra-fine grinding of feeds for prawn, turtle, eel and young animals.

SWFL B/C series ultra-fine grinding machine mainly consists of a stander, a grinding system, a grading system, a feeding system, a hydraulic opening mechanism as well as a main motor driving part for grinding and a motor driving part for grading (see Fig.1). The grinding system is composed of a main shaft, a grinding disc, a toothed ring and a grinding chamber; the grading system is composed of a grading impeller shaft, a grading impeller, a convex cover and a discharge chamber. The main motor runs in vertical driving way; the frequency conversion motors with frequency converters are used for both grading and feeding, so as to realize steeples speed regulation and remote control.



Preparation and inspection prior to first test run

1. Open the grading system, and check for any metal or sundries in the grinding chamber;
2. Check for any metal or sundries in the feeding bin or feeding screw;
3. All fasteners must be carefully checked for any looseness;
4. Check whether the driving belts are properly tensioned and the guard hood is well mounted;
5. Check each driving part on the grinding machinery for collision, analyzes the reason if any, and then put it right as soon as possible;
6. Turn each driving part and see whether there is any abnormality, and then inch each driving part and check whether they rotate in a correct direction;
a. The rotating direction of the grinding disc: clockwise in an overhead view.
b. The feeding screw: rightward.
c. Rotating direction of the grading impeller, normally it is clockwise in an overhead view. It can also be changed into counterclockwise according to actual situation.
7. Keep idle run of the hammer mill for 20-30 min. and observe its current, temperature and vibration: The temperature rise of the main shaft bearings should not exceed 35, and the maximum ℃temperature should not exceed 70 ℃(the ambient temperature should not exceed 40 ℃). The vibration amplitude of the machine should not be too large. And the machine cannot be loaded until it runs idly in a normal way.
8. During working, properly open the upper air gate of the gravity impurity removing chamber of the machine. And adjust the position of balance weight block on the gravity cover that is at the bottom of the machine so that it can open automatically when there are many impurities.
