Belt Conveyors

Belt conveyors are often used in a wide range of industries including grain, food, mining, plastic, chemical and many others. Belt conveyors can be used to transport powder or granular materials horizontally or on an inclined angle. Grain tech is able to supply a range of different types and capacity capabilities depending on the application.  Below are images of some models we can supply

  Belt conveyors nz

Slide Gate ValvesSlide gate valves nz

Widely used for loading and unloading control in grain, flour, feed, edible oil, food, metallurgy, cement and chemical industries. Heavy duty construction providing simple and reliable operation. Easy installation and low maintenance. Can be supplied pneumatically, electrically or manually actuated.




Diverter Valves Diverter Valves nz

Simple and compact structure that is easy to install and reliable. Pneumatically actuated utilizing high quality low maintenance components. Can be supplied in square or round inlet/outlets as well as in 30° and 45° configurations. Two way and three way valves are available.

Rotary Distributor ValvesRotary Distributors nz


Suited to handling both granular and powdered product within high capacity bulk material handling applications. The diverter is driven from an inline gear drive unit, complete with electric braking device.

The TFPX Series features a secondary sweep arm, which operates to prevent any accumulation of material within the actuating area, and a flexible seal is fitted to the chutes to ensure a dust-tight fit up against the outlet facings.




Magnetic Separators

Magnetic Separator nz


The TCXT series of rare earth tube magnets are used in the removal of iron particles prior to processing equipment. Featuring a ≥3000GS magnetic field intensity resulting a ≥99% efficiency of removal of ferrous metals.




Flexflo Core-less Augers

The flex-flo core-less auger system we sell is a simple, high quality, highly energy-efficient, fully-enclosed auger system which is extremely long wearing, and trouble-free. It can move feed up, down, on-the-level, or around corners using pre-formed elbows. The high tensile strength spring-like steel auger rotates in a specially-compounded ultraviolet- & wear-resistant PVC tube.

Z Pattern Bucket Elevators Z pattern Bucket Elevators nz


These elevators are designed and manufactured for continuous and quiet operation to gently transport a variety of free flowing materials in dry, semidry and moist conditions. They are particularly suited to handling grain, seeds, pulses and oil seeds where careful transfer for damage avoidance is vital.

This bucket elevator is constructed in solid plate sections, which allows easy access for cleaning and also several configurations for initial installation and future re-configurations

The buckets are one piece, food grade, injection moulded polypropylene. The buckets remain horizontal, maximizing product capacity with any configuration and at all available speeds.

The roller coaster in feed configuration features overlapping buckets, which facilitated easy non-spill feed. The fully rotating buckets allow discharge at any point in a horizontal run, or over the end of the top horizontal section.

The chain is heavy duty available in a variety of material combinations. Spring tension chain take-up keeps the tension at a minimum to reduce wear. No intermediate sprockets are used: the chain is guided by rails

Intake receiving conveyor (from pit)

Grain Tech can manufacture and supply suitable conveyors for drive over pit truck discharge. The system comes complete with:

  • Shallow profile hopper fabricated from carbon steel
  • Top drive over grid suitable for discharged ingredients to flow through complete with heavy duty support members capable of supporting loaded truck and trailer units.
  • En Masse drag link design pick up conveyor
    • Horizontal in feed with inclination for discharge into the following bucket elevator
    • Fabricated from heavy duty carbon steel folded and welded casing suited for bolt together assembly. High tension conveying chain fitted with UHMW flighting

Pneumatic conveying units

The vacuum conveyor is designed for industrial applications incorporating heavy duty components and is the ideal transfer equipment, used for transporting powder and granular materials for feeding the materials directly into mixers, sifters and other processing equipment. It reduces the likely dust emissions and is GMP certified. It is widely used in the pharmaceutical, foodstuff, feedstuff, chemical and plastics industries and for general processing material handling applications.

Working Principle:

The vacuum conveyor consists of a vacuum unit (no oil, no water), feeding tube, PE filter, vacuum hopper, automatic control device, pneumatic discharging device and a compressed air pulsing unit.

Capacity (kg/hr)






















Aero Mechanical Conveyors (Disc and Tube)

Tube chain conveyor is designed to continuously convey fine powder granules and bulk materials. It can be installed as horizontal and horizontal and vertical and standalone vertical arrangement

For horizontal/ flat and horizontal/ upright, the chains and disks generate horizontal thrust to push the materials. When the internal friction of material is greater than the external friction of material on the tube wall, the material will move with the disks and form a stable flow.

For vertical/ upright, the chains and disks generate up vertical thrust. The under-feeding pattern prevents the product falling and generates lateral pressure that will reinforce the internal friction. When the internal friction is greater than the external friction and the product's dead weight, the product will move upwards with the disks and form a continuous flow.

Delivery capacity: 0.4-300m3/h according to model & size
Max. Delivery Distance: 80m (horizontal); 60m (vertical)
Power: 0.2-30KW according to model & size

Tube Chain Conveyor System's Features:

  1. Flexible: 3D with the tube chain conveyor
  2. Sealed Pattern: dust-tight
  3. Low Energy Consumption: low costs
