We specialize in design, manufacture and supply of high efficiency Screw Feeders & Conveyors for conveying/feeding various powders like Cement, Fly Ash, Micro Silica, Ice flakes and other dry powders. The Vertical Screw Assembly consists of the Horizontal Screw Feeder which is installed below a silo or a hopper and as the name appropriately suggests it takes the feed from it. This Horizontal Screw Feeder feeds the powder to a Vertical Screw Conveyor. The Vertical Screw Conveyor is a tubular screw mounted at 90 deg to the Horizontal Screw Feeder to convey & elevate/ load the powder to the required height for filling into a weigh hopper and/ or one or multiple silos with a Distribution Screw (which is another Horizontal Screw Feeder installed at the top of the Vertical Screw Conveyor). The Vertical Screw Assembly system is a mechanical powder loading system which is preferred & recommended over the Pneumatic Loading systems and or Bucket Elevators due to its ease of use, lesser maintenance & compact size. Also in a lot of rural parts of India where the raw material is sourced in HDPE bags and the facilities are not equipped for Pneumatic Loading our efficient & compact sized mechanical loading system which consists of the Vertical Screw Assembly & the Automatic Bag Slitting Machine serves as the perfect solution! For more information on our Automatic Bag Slitting Machine. Salient Features Continuous flight welded on center pipe with variety of pitch, anti-wear coating (For special applications) Choice of tubular or troughs for Horizontal Screw Feeders. Available in different diameters to match the required capacities & lengths. Our screws are equipped with hanger bearings (can have multiple hanger bearings depending upon the total screw conveyor height), end bearings with application specific sealing protection, in line drive mechanism with single or double stage flange mounted reduction gear box and TEFC 4 pole sq. cage induction motors which can be mounted either on inlet or outlet side of the Horizontal Screw Feeder and outlet side of the Vertical Screw Conveyor.

Stainless steel screw Available in tubular & trough version with wide range of diameter & length Available with option of coarse & fine feeding Mirror or matt finish WAS version (without intermediate support) for handling tricky & abrasive powders of chemical Industry Safety features such as limit switch, zero speed switch provided Also available with jacketinsulation option for conveying hot & cold material.

The Spreader Screw is a specially developed Screw Conveyors for the Spreader Screw Assembly used to spread/ sprinkle cement powder over the road in a uniform manner. As seen in the picture of the Spreader Screw above, there are slits provided at the bottom of the screw (Ventral side of the Screw Conveyor) to enable the powder to be spread across evenly. The setup or assembly of the Spreader Screw includes: Set of Screw Conveyors {Cosben Make} Butterfly Valves {Cosben Make} Vibrators {Cosben Make} Storage Hopper Control Panel Diesel Generator An Open Truck The entire assembly/ setup of equipment is mounted on an open truck. The objective is to mount the spreader screw assembly on the open truck which will move on a newly built road and the cement powder is spread uniformly. The Spreader Screw assembly moving on the truck ensures that there is even & equal distribution of the powder along the width & across the length of the road. The storage hopper holds the cement powder to be spread. It is connected to a screw conveyor. This screw conveyor extracts the cement from the storage hopper & conveys it to the Spreader Screw. The Butterfly Valve is installed below the hopper to isolate the hopper & the extraction screw conveyor. The Vibrators are installed on the hopper to ensure free flow of material. The Diesel Generator works as the Power source for all the equipment mounted on the truck. For more details on the working of this screw, please click on the Installation link below.

The Automatic Bag Slitting Machine is a versatile automatic emptying machine and earns it’s name owing to its ability to empty any type of bag be it paper, or HDPE of 25 - 50 kgs capacity. It is ideally suited to Indian conditions where the raw materials in bags are not properly sealed. The overall system comprises of : Feeding Conveyor Bag Emptying Machine Built-in Dust Extraction System Empty Bag Compactor Pneumatic Conveying System

the slide valves are generally used to adjust or fully stop the flow of bulk solid material inside silos, hoppers and similar closed volumes. our slide valves are available with square, rectangular and round sections. square sections are available from dia 100mm to 400mm round sections are available from dia 100mm to 400mm rectangular sections are available from dia 200mm to 300mm detailed specifications are available in our leaflet. special rubber paddings and wipers ensures tight sealing within the valves thus making it leak resistant.

Screw Feeders installed under a silo are usually connected/ bolted/ welded to a Dia 300mm butterfly valve. The reduction cone is a functional utility device that ensures smooth connection in case of the diameter of the screw being lesser than the butterfly valve. To get a better clarity, please do have a look at the product photo shown in the Slider above.

Vital safety component for silos to avoid any damage and casualties at site, while loading/unloading of material. Also known as Breather valve, as it balances the pressure inside the silo, breathing the air IN or OUT based on the requirement and safeguards the silo. Maintenance friendly.
