Quality of raw material or finished products based on its weight. The system basically comprises of a feed hopper with a discharge Gate and a weigh hopper with discharge gate. The product to be measured is continuously weighed and dispensed downstream. The weigh dispensed is added ( cumulative ) and finally shows the through put on the display panel

Applicable

• Tea industry
• Rice mills
• Fertilizes and chemical industries
• wheat flour mill etc.

Specifications

Weighing and packing of powder materials into bags with minimum losses and zero spillage is achieved through Indus bagging machines

1) Net weigher
2) Gross weigher

Net weigher

The product to be bagged is pre weighed and then dumped into the bag. Feeding device is usually a twin feed screw conveyor with coarse feed and fine feed arrangement, alternately a rotary feeder is used for feeding the product into the weigh hopper. The screw feeder / rotary feeder is controlled by a variable frequency drive to obtain Accurate results.

Gross weigher

The product to be bagged is directly filled into the bag. The bag clamping device is fixed on the load cells for weighing. A higher rugged conveyor along with a heavy duty stitching machine is used to convey and stitch the filled bag. Optional equipment like vibrator are for bag compaction table up / down mechanism for filled bag compaction is provided. We can also design and supply fully automatic Bag filling machines with auto bag pickup and auto bag guider and stitching mechanism.

Specifications

• Capacity : 5kg-50kg
• Accuracy : 0.5%fsr

Indus Bag Filling Machine are rugged, accurate and user friendly.

These Machines are very simple to operate. The operator feeds the quantity of material to be bagged through the keyboard of the controller. The bag is placed on the discharge chute and start button pressed. The bag gets clamped and immediately preweighed quantity of material is filled into the bag, and the bag is decamped and moves on to the stitching conveyor.

Applications

• Rice
• Sugar
• Dal
• Cattle Feed
• Chemicals
• Minerals
• Fertilizers etc

Any process involving proportional mix of 2 or more ingredients can be achieved by incorporating Batch weighing System. Indus Batch weighing System are built on PLC Based Control Panel with high precision Load Cells. Ideal to batch few grams to tons. Application include : Ready Mix Concrete, Ferro Alloys, Chemical, Animal feeds, Food products etc.. Various type of Feeding devices are chosen based on the material properties

The jumbo bag discharger or unloader is basically provided to unload required quantity of the product from the jumbo bag. We can also discharge the product completely into the downstream process.

The following are the options provided based on the product and the client requirements:

1. Screw feeder or rotary feeder for powder material

2. Sector gates or slide gate for granular material

3. Weighing system for controlled discharge by weight

4. Chamber with bag clamp for dust free discharge

5. Bag squeezer.

INDUS BELT WEIGHERS are reliable, accurate & durable even in the most demanding industrial application. The belt scale is an industrial equipment which measures the rate of flow and total quantity of material being passed over the scale in a time period. The load being transferred to the belt is sensed by 4 high precision loadcells & the speed is sensed by an Incremental optical encoder (Tacho Generator). These two signals are multiplied digitally at the microcontroller based panel. The load per unit length multiplied by speed of the belt gives the rate of flow while the Rate integrated over time gives the totalized value of material passed over the belt. 

Indus Control & Automation Pvt Ltd is well-known for Bag Filling Machines Manufacturers in Bangalore, India. It is used to fill the most difficult materials to handle, the products manufactured at Indus Control is of high quality and cost-efficient.

Unfilled bags are mounted by hanging the four loops of the bulk bags on the suspended weigh frames easy to reach posts. The inlet spout is secured to the flared end of the filling head by a slip ring seal. The slip ring allows proper positioning of the liner when used. The bag is then inflated and the weight is tared. The electronics has an inbuilt timer- the duration of inflation is time settable. The filling cycle is controlled by the microcontroller for fast and efficient filling. The set points programmed included the target weight, fast/dribble feed, table up / down, no of cycles, vibration on time etc. Once filling and densification are complete the bag’s inlet spout is released from the filling head and tied off. The bulk bag is dismounted from the machine with a forklift by simply driving under the pallet/bag, lifting it and backing out. The filling system can be complete with an upstream delivery device and the control system. The filling spout is concentric with 2 nozzles for AIR purging & aspiration systems. 

The jumbo Bag Filling machines are custom designed, the machines can be provided with a roller conveyor underneath, once the filling is complete, the bag is lowered onto the roller conveyor & then the conveyor is switched on & thereby moving the bag out of the machine. The jumbo bag which is placed on the pallet can be shifted by using a forklift. The bags are of HDPE material, with plastic liner inside. The bag sizes are chosen based on bulk density of the material. Normal bag sizes are 900 x 900 x 1200 mm or 900 x 900 x 1400 mm. The bags are of HDPE material, with plastic liner inside.

Indus is the leading Electronic Gravimetric Weigh Feeder manufacturers in Bangalore-India by incorporating state-of-the-art technology for regular set up of solids in bulk quantity.

The material to be proportionately fed is ignored the belt; flow (also accumulative value) of the fabric is measured and compared to line parameters of the PLC/PID controller. The deviation is corrected by control the speed of the conveyor through variable speed A.C. Drive (Closed loop control system)Two high precision load cells are used to measure the belt load and a rotary encoder used to measure the speed of the conveyor.

Conveying of product over required distance is achieved by pneumatic conveying. Other accessories like dust collection system, blowout elevator, roller conveyor, belt conveyor, screw feeder are also provided as per the customer requirement.
