Description
Tubular screw conveyor - Mechanical conveyor for powders

Mild steel, stainless steel 304 and 316L
Flow rate up to 25 t./h. depending on diameter and motorization
Standard, flexible or easyclean screw
The tubular screw is intended to maintain continuous operation of the process. The easyclean version ensures fast and effective cleaning, while the flexible version can easily avoid obstacles in a restricted environment.
Our tubular screw conveyors are available in 2 or 3 versions:
- Light duty (flours)
- Medium duty (animal feed, cereals, flour)
- Heavy duty (cement, lime, plaster, mining products)

Tubular screw conveyor
Tubular screw conveyor by Palamatic Process

Tubular screw conveyor tank loading
Continuous conveying of bulk or powdery products.

Mechanical conveying - Tubular screw conveyor
Stainless steel manufacturing screw conveyor.

Screw conveyor under industrial mixer
Continuous operation of the system.

Mechanical conveying
Tubular screw for bulk materials and raw ingredients conveying.

Mechanical conveying
The extracting screw is implemented under hoppers and ensures the dosage of the bulk materials. It includes an extraction thread at the start of the turn and a conveying thread. The extraction thread is a tight thread.

Mechanical conveying
The tubular screw is used for extraction under a hopper.

Palamatic Process tubular screw
During the conveying process, the screw only ensures the transfer. It has an identical pitch over its entire length which is equal to the diameter of the turn. The conveying thread is an elongated thread which prevents the bulk material from settling.

Double screw under hopper
Manufacturing of food flavours.

Processing screw conveyor
Screening and mechanical conveying of cereals.

Bag dum station with conveying screw
Tubular screw conveyor for feeding powder storage tank.

Tubular screw conveyor Palamatic Process
Hatch on tubular conveying screw for screw flight inspection.

Tubular screw under storage silo
Tubular screw under storage silo for raw materials: silica, clay, calcium carbonate, lithothamnium

Tubular screw conveyor tank feeding
Tubular screw conveyor for feeding calcium carbonate storage tank.

Tubular screw conveyor
2 types of bearings:
- Plated bearings for low pulverized bulk materials
- Offset bearings for powdery and abrasive products.

Preparation tank feeding
The process consists of a big bag feeding system (gravity conveyor), three big bag discharging stations and a tubular screw conveyor.

Tank feeding with raw ingredients
Powder feeding of processing tanks from big bags and sacks via a tubular screw conveyor.

Bulk materials pneumatic conveying

Tuular screw flexible connector
The purpose of this tubular screw conveyor is to dose the sugar at the outlet of the silo for feeding the vacuum conveying.
Mass flow rate: 5000 kg/h. on bulk materials of density 1.

Tubular screw conveyor reactor feeding
Discharge and pneumatic conveying of fluorinated derivatives.

Flexible connector industrial process under tubular screw
This tubular screw conveyor is used for mechanically conveying DICOA from the hopper outlet to the reactor.
