300L Explosion-Proof Sigma Kneader
A 300L batch changes the cost of getting the protection plan wrong. This kneader is configured around the customer’s required explosion-protection grade, operating conditions, material process and discharge route.
Product Catalog
Sigma Mixer Product Catalog
Use this Catalog to compare the available Sigma Mixer options before opening a detail page. Start with the variable that will affect your process most, then review the Product identity and supporting information on the matching page.
How to compare the options
Material and process
Begin with the material state, addition sequence, expected batch behavior, and any known temperature or vacuum question. These inputs help narrow which Product page deserves a closer review.
Capacity and testing scale
Use the batch target and testing stage to distinguish production, lab, and material-trial equipment. A card gives you a route to investigate. Project-specific configuration still needs discussion.
Discharge and downstream handling
Check how the material must leave the chamber and what happens next. Discharge, receiving equipment, cleaning access, and layout can affect which Product page you should review.
For a general machine question, review the broad Sigma Mixer machine route before opening a specialist option.
ALL PRODUCTS
5L Lab Scale Sigma Blade Mixer
Will the formula still behave once real kneading begins? HengMing's NH-5 gives R&D teams a full 5L working batch to put kneading, temperature control and manual discharge under conditions that matter before production equipment is specified.
Food Grade Sigma Z Blade Mixer
Food Grade Sigma Z Blade Mixer for gum base, date paste, chocolate and dough. Specify food-contact materials, feeding and discharge around your process.
Heated Sigma Kneader with Screw Discharge
When a sticky batch resists discharge, mixing is only half the project. HengMing configures heating and screw discharge around the material so buyers can resolve the discharge path before committing to a custom build.
Hydraulic Tilting Sigma Mixer for Putty
If a dense putty or paste batch cannot leave the chamber cleanly, a capable mixer can still slow the whole workflow. HengMing matches hydraulic tilting, temperature control and batch volume to the discharge and cleaning routine before the build begins.
Ball Valve Discharge Sigma Mixer
Configure ball valve discharge for sigma mixers above 20L around the material condition at discharge, the receiving setup and the preferred valve actuation.
Customized Sigma Mixer
Still deciding whether your material needs vacuum, temperature control, a special discharge route or fully stainless steel construction? HengMing turns the working target into a custom sigma mixer that can be reviewed before production begins.
Heating & Cooling Sigma Mixer
A batch can look workable at the start and still become too stiff, too soft or difficult to discharge when the temperature path is wrong. HengMing maps how your material needs to heat, hold and cool, then matches the jacket and circulation system to that route.
Hydraulic Tilting Sigma Mixer
When the batch is ready, getting it out should not become the next bottleneck. HengMing configures hydraulic tilting around the material, batch route and handling sequence.
Lab Sigma Mixer
Small-batch kneader mixer for laboratory testing, formula development and pre-order material trial.
Screw Discharge Sigma Mixer
Screw discharge sigma mixer configured around material flow, outlet direction and downstream handling.
Sigma Mixer
A general Sigma Mixer discussion becomes useful when the buyer can connect material behavior, chamber conditions and the batch exit route before comparing machinery options. The objective is a configuration brief that can be checked, not a catalogue choice made in isolation.
Vacuum Sigma Mixer
Remove trapped air and control enclosed mixing with an NHZ vacuum sigma mixer configured around your material and process.
Sigma Mixer with Spraying System
When a formula needs liquid addition during kneading, the buyer needs a feeding discussion that stays connected to the material state inside the chamber. This Sigma Mixer option is planned around the addition sequence, process conditions and cleaning expectations before the machine configuration is confirmed.
Stainless Steel Sigma Mixer with PLC
A stainless steel Sigma Mixer with PLC is selected when the buyer needs the control scope to follow a defined mixing sequence, not simply add more controls to the cabinet. Material stages, access expectations and the target level of repeatability should shape the project brief before the PLC configuration is confirmed.
Vacuum Sigma Kneader with Extruder Discharge
Does vacuum solve the batch but leave the hardest step to the end? HengMing configures vacuum kneading and screw extruder discharge around the material and the next production step.
Material Trial Mixer
A material trial mixer is not just a smaller version of a production machine. It gives the buyer a controlled place to turn uncertain material behavior into practical questions about the mixing path, contact surfaces, temperature stages and the information needed before a larger build is discussed.
Small-Batch Custom Mixer
A small batch is useful only when it answers the same process questions that shape the next stage. This custom mixer gives the buyer a practical way to discuss material behavior, batch handling and the options that belong in a specialized process brief.
Custom Discharge System
The right outlet is decided by what the material does after mixing. HengMing can discuss a discharge arrangement around material flow, batch size, cleaning needs and the equipment that receives the finished batch.
