Kotzur stops profits from blowing away

To keep its customer’s profits from blowing away, Kotzur has designed specific products to keep dust contained and controlled within a typical grain handling system.

Kotzur’s customers want to make the most of their purchases – especially when they’re buying grain by the tonne. 

As a result, the last thing they want to see is their product blowing away on the wind.

Bevan Austin, national sales manager at Kotzur, said this is one of the reasons the company provides enclosed equipment for grain processing.

“Controlling and capturing dust is typically a priority for product quality, occupational health and safety and handling efficiency,” he said.

“However, many of our customers are looking to capture and control the dust so they can either dispose of this by product or reintroduce into their system at a later point during the process.

“For us, when it comes to dust, we work with the customer to find out the issues they are facing, how the dust behaves in the process, and what we can do to ensure the client is getting what they need.”

Kotzur can incorporate several of their products into a project to help contain and capture dust. After grain is loaded into the grain handling system, it will usually flow up an elevator and then into an aspirator with an accompanying cyclone and then flow through a scalper to complete the cleaning process.

This described cleaning system is typically used in preparation of stock feed rations to clean grain prior to wetting, the aspirator divides the grain flow and cleans out the dust and husks from the grain, allowing for continuous flow through the system. Meanwhile, the dust is sent through to a cyclone. Here, solids are removed from the air and can be deposited for collection or disposal.

The grain will then be deposited into a rotary scalper, which removes undersize or oversized material – such as twigs or stones. This protects the rest of the equipment, particularly the flaker mills, from potential blockages or damage. 

Leigh Prior, Kotzur’s sales manager for Western Australia, said separating the dust at this part of the process removes headaches down the line.

“Generally, in a feedlot application when dust is sent into a tempering silo, the addition of moisture causes it to cake up on screws and hang up in the silo. This can cause blockages in the mechanical handling system and can result in significant downtime,” he said.

“By using a cyclone system, the handler can reintroduce the collected organic material later, or dispose of it.”

Not all applications can be designed the same way, and because Kotzur is an Australian manufacturer, it can customise the products.

Feedlot projects often go through several stages in the design phase as a business scales up. As it gets bigger, the ability to provide rolling, flaking and tempering becomes even more important. 

Dust also becomes more of a problem as more grain is moved within the system.

Prior said the company relies on repeat business and keeps in close contact with customers to ensure the application fits the project and the client’s needs.

“We build and design our equipment in Queensland. That means that we can provide shorter lead times and quick service.”

Drag conveyors are the tool of choice for Kotzur’s grain handling projects. They use a chain to drag a series of paddles, which in turn, drags the material along the length of the conveyor. 

A toothed sprocket is located in the head and tail sections, with the gearmotor installed on the head section. The specific design of thexconveyor ensures the chain always runs on a track liner to maximise the life of the chain. Wipers are also attached to the panel to help clean out the conveyor.

Importantly, the drag conveyors themselves are totally enclosed, sealing potential dust away from the elements.

Prior said technology is simple and proven.

“We’re not recreating the wheel, it’s a design that works,” he said.

Austin adds that all of the equipment Kotzur designs has a solid, robust construction.

“The quality of components is something we focus on,” he said. “We design things to last and be as simple as possible and easy to operate. This cuts down on maintenance and unnecessary downtime.”

“We can provide support if there is a breakdown, supply spare parts, and can assist with preventative maintenance where required.”

While on-farm storage is a big part of Kotzur’s business, the company is conscious of the changes occurring in the industry. The company has noted projects are increasing in size and has seen an increased demand for feedlot projects and commercial grain handling projects.

The company is gearing up to meet this new demand and focusing its effort all around the country.

“We think the storage and material handling industries are continuing to grow and we want to grow with them,” Austin said.

“Kotzur is looking for new opportunities with a mixture of private and commercial clients. It’s an exciting time.”
