Details of the small swinging pellet machine:

The small granulator can granulate the mixed powder or pulverize the dry material into the desired granules. It is suitable for small batch production in pharmaceutical, chemical, food, scientific research units, laboratories, hospitals and small health care products factories.

Small granulator details:

First, the scope of use

1. This machine is a kind of rocking action of a rotating cylinder. Through the screen, the wet powder raw material can be ground into particles, and can also be widely used for pulverizing the pressed pieces to become ready-made particles.

2. In the case of chemicals, the powder is used as a mixed powder to be granulated, and after drying, the tablet is pressed, and the lumps can be pulverized during storage to form a lump or a block formed during the chemical processing. Used in the food industry to treat confectionery and mixtures and wheat bran. In other industries, such as ceramics, plastics and the like, become shaped particles.

3. It is not suitable for solids, fluids, slurries or grinds.

4. The number of mesh screens should be set by the user according to the particle size requirements.

Second, the construction description

1. The fuselage is an independent rectangular parallelepiped, consisting of three parts: bearing frame, reduction gear box and machine base. The feeding powder bucket is connected with the bearing frame and extends out of the machine. The front end of the feeding base is designed to extend and land widely and smoothly, so it does not need to be installed and can be placed indoors.

2. Particle manufacturing device: The rotating roller horizontal device is under the hopper, and there are bearing supports at the front and the rear. It is driven by the rack to make a reverse rotation. The front bearing housing of the end face is movable. When the three screws are unscrewed, the front bearing housing and the rotating roller can be sequentially extracted. The two ends of the rotating drum adopt symmetrical convex couplings, which are not restricted by the reverse and easy to assemble and disassemble.

3, screen clamp: the device is on both sides of the rotating drum, made of steel pipe, with a long groove in the middle, the two ends of the screen are embedded in the groove, turn the hand wheel to wrap the screen on the outer circle of the rotating drum, hand The inner wheel of the wheel has a thorn wheel to support, and the elastic can be adjusted.

4. Reducer: It adopts worm gear transmission, the speed ratio is 1:30, the storage can be stored in the box, ensuring good lubrication and no noise of the rack, gear and worm wheel. The outer end of the worm wheel is equipped with an eccentric rod to drive the rod to reciprocate. Movement, the gear shaft meshing with the rack is used for reverse rotation.

5. Machine seat motor: The motor mounting plate is hinged to the base of the machine, and the other end is hinged to the nut. When the hand wheel on the base is rotated, the screw is rotated, and the nut drives the motor board to the lower part to adjust the triangle belt to be tight.

Third, the machine parts lubrication

In the gearbox, the oil is stored in the gearbox, and the oil transmission line is lubricated by the worm wheel. Each of the transmission parts is engraved with a oil line on the sight glass, and there is a oil plug at the rear of the box for oil discharge. Open the upper cover of the fuselage to add lubricant to the bearings in the middle and rear bearing housings. The grease grease parts are listed in the table:

Serial number	Lubricating part	Time/ time	Lubricating grease
1	Front bearing	Every shift	HJ-30 mechanical oil
2	Middle and rear bearing housing	Every three months	ZG-2 lubricant
3	Gearbox inner bearing	Every three months	HJ-30 mechanical oil

Fourth, the installation instructions

1. This machine is packed in the whole box. After unpacking, move it to the appropriate place of use and use it after leveling.

2. The electrical circuit device is not restricted by the direction of rotation. The line is connected to the switch via the belt cover under the base, and the cable card is clamped.

Five, instructions for use

1. Usage: Start the machine and pour the mixture into the bucket. The rocking material is pressed by the rotating drum to form particles. If the crushing block is used, it should be gradually added. It should not be filled up to avoid overpressure. And make the screen vulnerable. 2, Note: If the powder does not stop inside the powder bucket, do not shovel by hand, so as not to cause injury, use bamboo shovel or stop work.

Six, maintenance instructions

1. Regularly check the parts and check them once a month to check whether the worm gears, worms, bearings and other activities are flexible and wearable. It is found that the defects should be repaired in time and should not be used free of charge.

2. The machine should be placed in a dry and clean room. The atmosphere should not contain acids and other places where corrosive gases flow to the parts.

3. After the machine is used once or when it is stopped, the rotating drum should be taken out to clean and brush the remaining powder in the bucket, and then installed, ready for the next use.

4. If the deactivation time is long, the machine must be wiped clean, the smooth surface of the machine is coated with anti-rust oil, and the cloth is covered.
