Tennant Specs & Spiroflow Design Mineral Powder Handling Solution to Meet Strict Quality Standards

The following is a guest blog post from Tennant Specs' partner Spiroflow Systems, Inc.

Spiroflow recently partnered with Tennant Specs to help a major North American energy technology company implement a bulk bag unloading and mixer feed-in solution that met strict safety and quality standards.

Leveraging Tennant Specs’ deep oil industry expertise and Spiroflow’s custom, industry-leading dry bulk material handling equipment, we were able to together engineer the perfect solution to help this oil industry giant. Today, the client safely and efficiently unloads and processes nearly 100 mineral powder recipes with 20 different base products at the facility.

The Background

At Spiroflow, we are always happy when Tennant Specs calls us to partner. They are an experienced and knowledgeable group known for their oil and gas industry expertise. Their level of expertise is highlighted by the strength of their client relationships.

Tennant Specs told us that their client had an existing facility at which it wanted to upgrade its equipment. They needed a bulk bag unloading and feeding solution that ensured dust from the mineral powders being processed were adequately controlled and contained - all while working around the technical challenges presented by confined space in the facility.

The Field Study

At Spiroflow, we value Tennant Specs’ commitment to understand the current situation before creating an engineered solution to meet the requirements. As part of its best practices, Tennant Specs commissioned a week-long field study to monitor the operations and identify points for process optimization. This field data and due diligence was invaluable in putting together the comprehensive solution to meet the client’s needs.

The Solution

Working with Tennant Specs, we were able to put together a mineral powder discharging, handling, and feeding solution with the following Spiroflow equipment:

The comprehensive solution enabled the client to discharge 2000lb bulk bags, or smaller 50lb bags, in a custom combination discharger and efficiently feed the wide range of powders into mixers. The system also included low headroom hoists to help overcome the technical challenges of fitting the equipment into the space available. Spiroflow also customized the equipment with integral dust collectors to ensure dust containment at in-feed points. Spiroflow’s custom dischargers were able to be paired with the most appropriate conveyor from their wide range of offerings allowed an optimal solution to be provided.

A big thank you goes out to the team at Tennant Specs for their partnership in creating this successful solution. We cannot wait to help support you and your clients again soon!
