The lab model Double Sigma Blade batch systems provide complete, homogeneous mixing, even in small quantities.

 

The mixing action is a combination of bulk movement, shearing, stretching, folding, dividing, and recombining as the material is pulled and squeezed against blades, saddle, and side walls. Continually new layers of material are compressed and folded over one another and are subjected to shearing forces.

Working Principle of Sigma Mixer

In Sigma mixer tangential action of mixing and kneading obtained by ‘Z’ type (SIGMA) shaped kneading blades, which rotates very accurately at different speed towards each other causing product to be transferred from one end to another end. Discharge of the finished product is achieved by tilting the container or through the valves at the bottom or by means of an extrusion screw beside the container.

The mixing action is a combination of bulk movement, stretching, folding, dividing, and recombining of the material. The shearing & tearing action of the material against blades and the side walls causes size reduction of the solids. After the time period required for sterilizing the batch has elapsed, the heating circuit shuts of the pneumatics damper (exhaust) opens and cooling operation commences.

In the tangential design, the blades rotate in the trough meeting tangentially. The front blade generally rotates faster than the rear blade usually in the ratio of 3:2. Tangential blades are generally used for material of higher viscosities such as adhesives, rubber compounds, flush colors, dyes, and pigments.

In the overlapping design, the blades overlap above the saddle of the container. Due to the overlapping action, it is necessary that the relative position of the two blades is unchanged, and as a result, both the blades rotate at the same speed. Materials that flow freely or creep down into the blades are mixed using the overlapping blade action. This design offers a faster interchange of material from one blade compartment of the mixer to the other. Overlapping blade action is used for materials of lighter viscosities such as carbon pastes, clay coating, creams, and ointments. The overlapping blade produces a lower kneading and shearing compared to the tangential blade action

Vacuum kneader preparation before operation

1. Check whether the fasteners are loose, whether the steam pipeline is leaking, and whether the circuit and electrical equipment are safe. The electric heating type kneader must have a grounding device.
2. Clean the kneading chamber before the test machine. Do 10-15 minutes of dry run, confirm that the machine is running normally, and then put it into production. Generally, the gears (including the reducer) of the new machine are noisy when they are used in the initial stage, and they will naturally decrease after some time.
3. After the machine is installed, first clean, decontaminate and wipe the anti-rust grease. Check each lubricating point and inject lubricating oil (grease).
4. Check the tension of the V-belt before driving, and move the motor to an appropriate position by adjusting the bolt.
5. When steam is used for heating, a safety valve and a pressure gauge should be installed at the steam inlet pipe, and the steam pressure must not exceed the working pressure requirement of the mixing tank indicated on the label.
6. The use of inversion should be reduced when kneading with the paddle.

Precautions for vacuum kneader

1. When stirring, the lid should be covered and the bolts should be tightened. The shaft end is equipped with an adjustable sealing sleeve, which can be adjusted when the material is leaking. Do not put your hands on the cylinder mouth when the cylinder head is lowered to avoid crushing your fingers.
2. Pay attention to the rotation range of the cylinder when lifting and lowering the cylinder of the vacuum kneader, so as not to hurt the human body. Stirring should be stopped when discharging.
3. If any abnormal phenomenon is found when the vacuum kneader is working, it should be stopped immediately, and measures should be taken to eliminate the fault. It is strictly forbidden for the machine to work under abnormal conditions.
4. The vacuum kneader adopts electric heating, steam, oil heating, water cooling, and other methods for temperature adjustment, and adopts hydraulic cylinder turning and covers the opening. The discharge methods include hydraulic pressure, cylinder dumping, ball valve discharge, screw extrusion, etc.

How to Improve Ribbon Blender Efficiency?

Across the process industries, a wide range of powder blends are produced in a ubiquitous workhorse that is the ribbon blender. From seasonings and beverage mixes to pharmaceutical, chemical, plastic, and agricultural powders, a reliable method for solid-solid blending is at the core of production and the ribbon blender is a popular choice due to its efficiency and economy.

Ribbon Blender

A ribbon blender consists of a U-shaped horizontal trough and an agitator made up of inner and outer helical ribbons that are pitched to move material axially, in opposing directions, and also radially. Agitator tip speeds in the range of 300 feet/min are typical.
Selecting a suitable ribbon blender for a particular application starts with bulk density. Bulk density determines if a standard or heavy-duty blender is required and, given a target batch size (weight), the bulk density defines the ideal blender model (capacities are normally listed in volume). Ribbon blenders are offered with optional features like heating/cooling jacket, vacuum capability, interchangeable paddle agitator, lump breakers, sanitary finish, and even wetted parts constructed from special alloys. More recently, new features have become available that are designed to maximize efficiency, blend consistency, and productivity. Ask your blender manufacturer about the following options:
how to make ribbon blender
• Scrapers welded to the spokes and ribbons. Scrapers having a close tolerance (around 1/8 in.) to the end walls significantly reduce the amount of materials that might tend to pack in the blender’s outermost areas. ‘Radiused’ trough corners further eliminate any dead spaces in the product zone.

• Clear view cover and shaft guards. The pictured ribbon blender features FDA-approved poly carbonate shaft guards and sections of the cover. The multi-piece cover is equipped with multiple ports for ingredient additions, lights, spray system, venting, and vacuum, which significantly increases ease of use and worker safety. Operators can safely monitor the contents of the blender and charge raw materials while the agitators are running. Without the need to stop agitation and open the covers at multiple intervals, cycle time is therefore optimized and unnecessary dusting issues are prevented.

• Air-purged mechanical shaft seals. Special seal arrangements such as air-purged mechanical shaft seals eliminates the risk of product leakage, preventing premature bearing or drive failure and shaft wear. Air purging creates a higher pressure inside the seal cavity, creating an air barrier that helps keeps material inside the trough and adds to the life of the wearable parts of the seal.

• Pneumatically-operated spherical disc valve. This style valve provides a large opening and minimizes dead space. Discharge connections can be customized to perfectly mate with your downstream material handling system.

• Custom PLC recipe controls. There are multiple benefits to applying PLC recipe controls to a blending process: batch-to-batch consistency, automated data logging, reduced operator error, faster changeovers, and longer service life, just to name a few. Recipes can be written and stored into memory, so that switching the batch protocol from one formulation to another takes only seconds, maximizing production time. Pre-programmed maintenance screens can help save equipment from downtime due to preventable maintenance issues, reminding technicians to check greases, seals, bearings, and other components after a certain number of run hours. In a customized control scheme, hardware can also be networked to existing systems that may require a degree of handshaking with other equipment in the overall process. SCADA systems, software programs, special protocols, and network concerns should all be addressed early into a project to ensure complete compatibility.
