Cement packing machine

Numbers of discharge hole: 6-12

Production capacity: 1200-3000 bag/h

Cement packing machine is a cement bagging equipment for cement packing in the finished cement production, also known as cement packer. It is used for not only automatic packaging of cement, but also powdery materials with good liquidity, such as fly ash and cement additives, and etc. so the cement packing machine is widely applied to the medium-size cement plant or mini cement plant.

The cement packing machine is mainly used for many industries, such as the chemical industry, building materials, mineral processing, highway, railway, and underground construction, which not only bring great convenience to these industries but also bring considerable benefits and efficiency.

As for the cement packing machine types, most of them are fixed type and rotary type. Fixed cement packing machine refers 1-4 mouth packing machine, the cement filling is completed by manually moving bag. Rotary cement packing machine refers to 6-14 mouth type, the packing machine rotates to complete cement filling without manual work.

Advantages of cement packing machine

  • Stable operation, reduce the dynamic vibration and create good conditions for measuring and weighing.
  • Reasonable structure, the central feeding of the cement packing machine is convenient for electrical circuits to be arranged outside the rotary silo, the circuits are not easy to overheat, easy to maintain.
  • Wide applications, apply for powdery or particle materials with good fluidity.
  • Highly automatic, basically realize automation, filling, metering, bag dropping, and other actions are completed by one set of cement packing plant automatically and continuously.
  • Clean and environment-friendly working environment, if the bag weight is less than the specified value, the bag will not drop. If the bag falls off unexpectedly, the gate will be closed immediately and the filling will stop.
  • Easy maintenance, less vulnerable parts, no hydraulic, pneumatic components.

Cement packing machine working principle

Put the cement in the stock bin into the outlet of the cement packer, start position switch, send the signal to the microcomputer and start the solenoid valve, open the discharging mouth by the operation of the air cylinder. Cement materials are filled to woven bags continuously through the discharging mouth by the impeller running at high speed. When the weight of the bag reaches the set value, the signal is transmitted to the microcomputer by the sensor. The solenoid valve controls the cylinder through the microcomputer to close the customized filling of the discharging mouth. At the same time, the solenoid valve sucks through the signal of the inductor, and the bag presser makes the bag tilt off automatically.

The whole cement filling process is controlled by electricity, except manual inserting bag, cement bag pressing and opening and closing of discharging mouth; Cement filling, weighing and measuring, automatic bag dropping and other functions can be completed automatically, so as to reduce mechanical faults and ensure the fast operation of packaging equipment.

Notes for cement packing machine

  1. Check the power of the cement packing machine before starting, and then start feeding device or open the gate; turn off the feeding device before off the packing machine, then turn off the power to prevent the packing machine ash system from being blocked.
  2. Check the weighing device frequently, and especially pay attention to the use and maintenance of traction electromagnet. If the body shakes too much, you should find out the reason in time to deal with, and check the anchor bolt fastening.
  3. Clean the bagging mechanism regularly, there should not be grazed, caught, stuck, and other phenomena.
  4. Do not press the cement bag by hand in the cement filling process, so as to keep the weighing accuracy.
  5. It is necessary to carry out dynamic weighing calibration again once you removing and assembling the spring pieces on the bagging rack.
  6. The main shaft of the powerhead of the flying mechanism shall be lubricated with butter and greased at least twice a week.
