Lime Storage and Mixing Plant




Bulk Technik is a local company that was established in 1988 and is active throughout South Africa and the neighbouring countries in the field of materials handling (storage and conveying). Our first-rate capabilities and mastery of the key technologies include: lime slaking, pneumatic conveying, screw conveyors, bulk storage silos. We rank among the global leaders in design and construction of bulk materials handling equipment.

As a reliable, service driven and competent partner, we offer our customers extensive expertise in the listed fields of materials handling and engineering. By supplying economic solutions, we help our customers attain sustained success and competitive advantages.


Bulk Technik supplies a wide range of standard equipment for storing and handling bulk materials as well as custom designed products and plants specifically engineered to our high standards and our customers’ needs. Our equipment is designed using the latest 3D computer software and analysed using both conventional design calculations as well at finite element technology (FEA), which enables our engineers to perform complex stress analyses.

The Bulk Technik designed products comply with the highest quality standards and have been engineered and developed with our vast expertise and experience that we have gained over the many years in materials handling. Our range of equipment is suitable for most powder and granular products in the food and non food sectors. Our main areas of expertise include:

  • Bulk storage silos: for the storage of powdery and granular materials such as bran, cement, coal dust, flour, lime (hydrated and unhydrated), soda ash, sodium sulphate and wheat. Both mild steel and stainless steel silos can be offered with sizes ranging from small hoppers to over 1400 t capacity
  • Pneumatic conveying systems for a diverse range of bulk products, from very abrasive to delicate materials. These will be conveyed via one of the following pneumatic systems:
    • Dilute phase conveying systems
    • Dense phase, low velocity conveying: Takt-Schub, Fluidstat or Fluid-Schub systems
    • Jet conveyor systems
    • Vacuum conveying system
  • Burnt lime storage, handling and slaking plants with detention slurry-type slakers (slaking capacities from 0.6 to 5.5 t/h)
  • Hydrated lime storage, dosing and slurrying installations
  • Storage Silos - standard sizes as well as custom designed
  • Weigh-batching and mixing plants
  • Screw conveyors and screw feeders - tubular and trough as well as dosing feeders
  • Dust measurement - agents for SWR Engineering for German quality dust and flow measuring instruments

 The fundamental design of our equipment has not changed significantly over the years, however, we are continuously improving our products with the advancement of computer software, newer materials as well as more modern production facilities and methods. Our equipment is designed to not only provide reliable service, but also allow for easy maintenance as well as optimised to make use of modern fabrication processes. Many components are laser cut or water jetted in order to provide the best accuracy, product quality as well as interchangeability.


AKO Pinch Valves

Bulk Technik has the local agency for supplying the German made AKO pinch valves. Both pneumatically and mechanically operated pinch valves are available and over 11 different types of sleeves can be supplied to best suit the process conditions. The AKO pinch valves have superior sleeves that are wear resistant and are easily replaced, reducing system down time.ako logo



DMN Westinghouse

This global leader manufactures rotary valves and diverter valves for all industries. The innovative designs for easy cleaning, quick maintenance and proven reliability make DMN Westinghouse the obvious choice for almost any application. The rotary feeders are available as airlocks i.e. drop through or the blow through type which is used for pneumatic conveying applications.


SWR Engineering

Bulk Technik has to sole agency for the leading range of dust and flow measuring instruments supplied by SWR Engineering. These instruments can be used for material mass flow measurement for both dilute phase and dense phase conveying systems; measure dust emission in exhaust ducts, even at temperatures of 700 deg C; be used for level measurement; dust filter monitoring



Bulk Technik is currently a Level 5 B-BBEE contributor. Our company’s ongoing efforts have seen its grading increase over the years. A copy of our current certificate is available on request.



Bulk Technik has implemented a number of steps to reduce their carbon foot print and protect the environment. Our company is currently building new premises which will make use of natural light source as well as LED lighting. Hot water will be generated by a solar heating system that will have a heat pump as back-up. Power is generated by a solar plant which was designed and engineered by Bulk Technik. The SMA grid-tied inverters generate sufficient power to run the office completely off the grid. A LiOn battery pack provides back-up power and also increases self-sufficiency. The offices make use of natural cooling thereby eliminating the use of air conditioning in the summer months.

Our company policy and design guide is to reduce the carbon foot print of our products. This will include design and manufacturing methods that are more eco-friendly with the main aim of offering systems that will have a reduced impact on the environment. Thus our clients will benefit by, for example, a reduction in power consumption. 

Please make use of the carbon foot print calculator. It is a useful tool to determine the amount of CO2 being produced and conveniently converts it into the number of trees that should be planted.
