Chemical Machinery & Plant

We offer a complete product range of Sigma Kneader and Agitator - Stirrer

Sigma Kneader

Total Capacity(Liters) 8, 75, 150
Working Capacity(Liters) 3- 5, 35-50, 70-100

The Sigma Mixer is used for mixing and kneading for mixing, kneading of highly viscous mass, sticky and dough like products, Mixing of pastes, rubber, and heavy plastic masses, applications in Food, Rubber, Pharmaceutical, Chemical and agro industries, Dry powder to wet phase mixing. This mixer is most suitable for highly viscous material and dough like masses. The sigma kneader is a double arm mixer, the two Z blade rotate towards each others at same or different speed inside a W- shaped product container. The twin screw basin kneading machine with two horizontally arranged kneading blades, which are deeply geared into one another and strip themselves reciprocally. Each blade moves the material in opposite direction thereby providing excellent cross mixing of all raw materials. The blades pass the trough walls and each other at close clearances resulting in good mixing. The close clearance produces a shearing and tearing action that is beneficial to the size reduction of solids. Selection of appropriate blade shape and speeds result in excellent mixing

Agitator - Stirrer

Application & Process:

At PRISM, We design and manufacture a wide range of agitators for liquids and Paste for all process in the pharmaceutical, chemical, food, cosmetics and similar industries. Agitators are provided with different types of agitation components for process such as mixing, blending, dissolution, dispersion, homogenization, reaction, fermentation, oxidation, digestion and emulsification of liquid, paste, ointment, solution, viscous material and solid-liquid.

Agitators are designed and adapted to any vessel shape and can be implemented with or without lower support. Different types of blades can be combined depending on the process requirements. The sealing system are designed and adapted depending on the requirement of the various process and start from simple retainers to double mechanical seals. Agitators are available with different type of mounting as per suitability of the process and users requirements.

Different types of blades can be combined depending on the process requirements and various conditions including the stirring objective, tank shape, rotating speed, viscosity, mixing blades of different configurations should be applied for different operating objectives. Different mixing blades follow various specifications to design and select the configurations of the blades. The ratio of the blade to the inner diameter of the tank, angular speed of the blade top, viscosity change during mixing process and the range of the flow volume are the factors to be considered. There are various types of blade mixer and can be categorized into axial flow and radial flow according to the flow pattern of the fluid in the tank. The main factors affecting mixing performance are as below and the commonly used configurations are listed for reference:

Shape, diameter, sweep back angle and slant angle of the mixer blade.
Number of layers and the vertical position of the mixer blade where it is installed.
Rotating speed of the mixer blade
Shape, inner volume, number of baffles and outline dimensions of the mixing tank
Batch operation or continuous operation.

Agitators available with different type of drives and speeds with direct motor and with gear drive as per process requirements. Agitators are suitable for mixing volumes 5 liters to 10, 000 liters.
