Q1: What is a kneading machine?
A kneading machine is a device that mixes, stirs, and kneads high-viscosity, high-density materials (such as rubber, plastic, food raw materials, chemical materials, etc.) through two counter-rotating stirring paddles (usually Z-type or Sigma-type). Its core function is to make the materials evenly mixed or undergo physical/chemical reactions through shear force and extrusion force.
Q2: What are the main types of kneading machines?
By structure: horizontal kneading machine, vertical kneading machine.
By function: ordinary kneading machine, vacuum kneading machine (with vacuum degassing function).
By heating method: steam heating, electric heating, oil heating, etc.
Q3: What industries are suitable for?
It is widely used in rubber, plastic, food (such as dough, chocolate), pharmaceutical, chemical (such as pigment, adhesive), battery materials and other industries.
Q4: How to start the kneading machine correctly?
Check whether the equipment is clean and whether the lubrication system is normal;
Close the discharge valve and feed according to the capacity requirements (it is recommended not to exceed 70% of the volume);
Start the main motor and gradually adjust the speed of the stirring paddle to the process requirements;
After mixing, stop the machine and open the discharge valve to discharge the material.
Q5: Possible reasons for uneven material mixing?
Too much or too little feeding;
The speed of the stirring paddle does not meet the process requirements;
The viscosity of the material is too high, resulting in poor fluidity;
Insufficient mixing time.
Q6: Does the equipment need to be heated or cooled?
Depends on the process requirements:
Heating: used for materials that need to melt or promote reaction (such as rubber vulcanization);
Cooling: to prevent the material from denaturing due to friction heating (such as some food raw materials).
Q7: What are the key points of daily maintenance?
Clean the residual material on the inner wall of the equipment and the stirring paddle after each use;
Regularly check the amount of lubricating oil (gearbox, bearings, etc.);
Check whether the fasteners (such as bolts) are loose;
Record operating parameters (temperature, speed, current, etc.).
Q8: What should I do if the agitator blade is worn?
Minor wear can be repaired by grinding;
Severe wear requires replacement of new blades to avoid affecting the mixing efficiency.
Q9: How to maintain the equipment when it is out of use for a long time?
Thoroughly clean the interior and apply anti-rust oil;
Disconnect the power supply and cover to prevent dust;
Manually turn the agitator blade every month to prevent the parts from getting stuck.
Q10: What should I do if the motor overload alarm alarms?
Check whether the material is over-dosed or the viscosity of the material is too high;
Reduce the speed of the agitator blade;
Eliminate mechanical obstruction (such as foreign matter entering the chamber).
Q11: What are the possible causes of abnormal noise during operation?
Bearing wear or insufficient lubrication;
Gearbox failure;
The agitator blade collides with the chamber (installation offset or deformation).
Q12: How to deal with discharge valve leakage?
Clean the residual material at the valve port;
Check whether the sealing ring is aging or damaged;
Adjust the valve clamping device.
Q13: What safety precautions should be taken during operation?
It is strictly forbidden to put your hands or tools into the cavity during operation;
It is forbidden to open the protective cover when the equipment is running;
Wear heat-insulating gloves when working at high temperatures.
Q15: How to avoid cross-contamination of materials?
Clean the equipment thoroughly before producing different batches of materials;
Use special cleaning agents for sensitive materials (such as medicines and foods).
Q16: How to choose a suitable kneading machine model?
The following factors need to be considered:
Material properties (viscosity, corrosiveness);
Single processing volume;
Whether heating/cooling functions are required;
Material requirements (stainless steel, carbon steel, etc.).
Q17: Warranty period and after-sales service policy?
The standard warranty period is 1 year (subject to the contract);
Remote technical support and on-site repair services are provided.
Q18: How to obtain spare parts or technical support?
Please contact the manufacturer and provide the equipment model. It is recommended to use original accessories to ensure compatibility.
