A brief overview:

The machine is a new granule new equipment which uses the crystallization water in the powder (water content is 0.5~5%) to directly degas, retract and granulate the powder.

The model has reasonable structure, stable and reliable performance, convenient cleaning and maintenance, high power, high output and good particle flowability.

The granules made by this machine can be pressed into tablets, used as granules, tube capsules, etc. The machine is mainly used for granulation in pharmaceutical, food, chemical and other industries. It is especially suitable for granulation of wet and unsolvable materials. The machine can be used in combination with a spray dryer, a mixer, and the like.

• The main technical parameters

• Mechanical behavior

1. The machine consists of lifting, feeding, tableting, granulating, hydraulic, cooling, rack, outer seal and electrical components.

(1) The lifting part is realized by the hydraulic lifting cylinder to raise and lower the feeding mechanism, and the position switch is used to control the position, and interlocked with feeding, pressing and granulating.

(2) The feeding part is driven by the Y100L1-4 motor to drive the screw with different pitch of the double cone to pre-press and degas the powder. According to the performance of different materials, the feeding speed can be adjusted steplessly (frequency control).

(3) The tablet is driven by the Y132M-4 motor to drive the BW27-29-7.5 cycloidal pinwheel reducer to rotate the drive shaft, which drives the relative rotation of the two pressure rollers to work together with the pressure to compress the powder into a sheet.

According to the compressibility of different materials, the pressure roller can be adjusted steplessly (frequency control)

1. The whole part is rotated by the variable frequency speed regulation 1.5-2.2KW motor to rotate the whole knife to form the particles required for the formation of the sheet material in the mesh.

(5) The pressure part is supplied by the electric vane pump to the oil cylinder, and is regulated by the energy storage device. The upper and lower pressure limits are set by the electric contact pressure gauge.

( 6 ) Cooling can be done by tap water or cooling water, through the HS-X32A two-way inner tube rotary joint, through the shaft hole to force the surface of the pressure wheel.

2. Production

It is mainly determined by the fluidity, compressibility, viscosity, humidity and fineness of the finished particles of various particles. Different materials have different yields. Appropriate measures can be taken to increase production.

1. Some materials have poor fluidity and compressibility. Under the premise of not affecting the performance quality of the pellets, the canteen can adjust the proportion of materials, add auxiliary materials, adjust the humidity of the powder, improve the fluidity of the materials, and the compressibility can be significantly improved. The production of granules.
2. In the chemical state of the powder family, the material state and the hardness of the pellets are required to be fixed, the pressure of the cylinder can be adjusted, and the speed of the feeding motor and the tablet extrusion (stepless) can be improved by the three states.
3. Adjusting the speed (frequency conversion) of the particle motor reducer can improve the yield of material particles (not less than 30%).
4. Some materials have high sensitivity, indoors can be kept at a constant temperature, some materials have strong hygroscopicity, and dehumidifiers can be used to ensure certain humidity. Some materials are afraid of light. Brown curtains can be used for shading: some materials are too viscous, and the hardness of 0.7 is good. Magnesium sulphate: Some materials have too small water content, can spray anhydrous alcohol, increase humidity, and thus ensure the normal production of the machine.
5. Due to the high heat generated by the high pressure, the material is discolored, and it is cooled by tap water or cooling water. The pressure of the pressure roller is below 45 °C, the water quality must be clean, otherwise it will easily block the passage and affect production.

4. Use maintenance and maintenance

1. After unpacking, check the certificate, the instruction manual, the packing list, whether the information is complete, and whether the spare parts are complete.

2. Check whether the parts are damaged during the transportation process and whether the fasteners are loose.

3. Switch on the water source, check whether the water quality and the inflow and outflow are unblocked, and whether the cooling system leaks.

4. Empty operation:

(1) Turn on the power and ground, turn on the air box air switch and the inverter air switch.

(2) Start the oil pump motor, pressurize the cylinder pressure test, adjust the overflow valve to 6Mpa, adjust the electric contact pressure gauge to 4~5Mpa, then check the pressure to check whether the hydraulic system is normal, whether the pressure gauge is sensitive, and whether the hydraulic system joint is leaking. oil.

(3) Unscrew the funnel seat bolts (6 M10 bolts) for the lifting test to check whether the fiber switch position is reliable and recover.

Note: When using the lift cylinder, the inverter air switch must be turned off due to electrical interlocking. The electric cabinet rotation switch is turned to manual and the electric door lock is opened to use the lifting cylinder.

Warning: When using the opening and lowering function, remember to first remove the funnel seat (6 M10 bolts).

1. Start the whole grain motor, tablet motor, feeding motor, adjust the whole grain to 700 rpm, and the other to 600-900 rpm, the time is not less than 0.5 hour, check whether the motor is hot, whether the mechanical transmission is normal, and the operation Whether the components are balanced, whether the group card and the reducer are leaking oil, whether the steering is consistent with the mark, whether the tension of the belt and the chain is appropriate, the cause of the fault is found, and the cause is eliminated in time. After the Zui, the reverse is reversed, the pressure is relieved, and the water source is cut off. ,power supply.

5. Granulation test:

Prepare the powder, control the indoor temperature, humidity <65, install the screen according to the requirements of the finished product, connect the water and electricity, start the oil pump motor, the rain pressure, start the whole grain, press the film, feed the motor, after 10 minutes of normal operation, Gradually add materials to the funnel, adjust the oil pressure and the speed of the tablet and feed motor in time, so that the three elements can reach the reasonable combination state.

1. If the tablet is loose, increase the pressure, increase the speed of the feed motor or reduce the speed of the pressure piece motor.
2. If the sheet material is too hard, the pressure can be reduced, or the speed of the pressure roller can be increased, or the speed of the feeding motor can be reduced. The gap between the two pressure rollers is 0.2 to 0.5 mm.
3. If the output is too low, the tablet and feed motor speeds can be synchronized.
4. If the tablet is not formed after the adjustment of the three factors, the proportion of the material can be adjusted within the allowable range, the auxiliary material is added or the humidity of the material is increased, and the alcohol is sprayed.

6. If the oil pressure is difficult to rise or the pressure drops too fast, check the oil pump motor and the deceleration valve check valve; if the pressure relief fails, check the solenoid valve; if the voltage is not good, check the energy storage device.

7. Lifting faults should check whether the throttle valve is adjusted, blocked, and related to oil leakage. The pressure is too low. Remember that the throttle valve is not adjustable too fast, and the rising speed must be slow when lifting.

8. If the material is blocked, after the total stop, re-connect the power, relieve the pressure, reverse the pressure wheel, or raise the funnel, take out the blocking material, let go of the funnel material, and after re-installation, reduce the feeding speed and speed up the tableting. The speed is, after normal operation, continuous production.

9. If the feeding is difficult, check if the V-belt is tight; whether the feeding screw and the funnel are stuck; whether the material is too light; or the material humidity is too small or too large.

10. The yield is low, whether the tablet is too loose; whether the whole grain speed is too fast, whether it breaks the net.

11. The equipment department and production department should be familiar with the production process specifications, familiar with the performance, maintenance and maintenance knowledge of the equipment, so that the equipment is in good working condition.

12. Do not mix hard metal in the material, otherwise damage the feeding screw, the surface of the blade pressure wheel and the screen.

13. Strict operation specifications, no overload operation, timely troubleshooting, timely replacement of damaged parts, material on the surface of the pressure roller, can not be removed and beaten with hard tools. Otherwise the surface of the pressure roller is damaged. The gap between the squeegee and the pressure roller surface is 0.1 mm.
