Explosion-Proof Sigma Kneader Mixer

Product Overview

Karvil Machinery provides a 500L explosion-proof sigma mixer designed for demanding applications involving flammable or volatile materials. This machine is specially built for our Turkish customer to mix cotton, alcohol, and other solvent-based compounds safely and efficiently. With more than 20 years of experience in industrial kneading technology, Karvil ensures reliable performance, compliance with safety standards, and durable construction.

Key Features & Benefits

• Explosion-Proof Design
  Both the main motor and hydraulic motor are Siemens BEIDE explosion-proof type, ensuring safe operation in environments with alcohols, solvents, and other volatile chemicals.

• Heavy-Duty Sigma Blades
  Equipped with double sigma blades for powerful kneading of sticky, fibrous, and solvent-containing materials. Forward and reverse operation improves mixing uniformity.

• Hydraulic System

• Hydraulic opening/closing of the top cover.

• Hydraulic tilting discharge for easy emptying, reducing labor intensity.

• Heating & Cooling Jacket
  The mixer is fitted with a jacket that supports both heating and cooling functions, giving operators precise temperature control over the process.

• Vacuum Capability
  The vacuum interface allows air removal from the product, improving density, homogeneity, and preventing oxidation.

• Large Capacity for Industrial Scale

• Total volume: 500L

• Working volume: 350L
  Ideal for batch production of coatings, adhesives, chemicals, and solvent-based materials.

Q1: Can this mixer be customized for my material?
Yes. Every sigma mixer we build can be tailored to match your material’s viscosity, flammability, and process requirements. We can adjust blade speed, motor power, jacket type (heating/cooling), and discharge options.

Q2: How safe is the mixer for alcohols and solvents?
This mixer is fully explosion-proof. Both the main and hydraulic motors are Siemens BEIDE explosion-proof type, and the machine is designed according to international safety standards. It is suitable for solvent-based production environments.

Q3: What is the delivery time?
Standard production usually takes 6–10 weeks, depending on the level of customization. We keep regular communication during manufacturing and provide trial videos before shipment.
