Minor and Major Weighing Systems


Sterling Systems & Controls, Inc. offers customized minor and major weighing systems to create a batch of material that requires accurately measured ingredients, which is critical to the batch integrity. These minor and major weighing systems (a.k.a. minor ingredient systems or minor ingredient batching systems; major ingredient batching systems) can be semi-automatic or fully automatic. As a part of our minor and major weighing systems, we offer supply bins, feeders, automatic bin refilling, work platforms, raw material bag handling equipment, dust collection, and batched material conveying equipment (pneumatic and mechanical).  Minor weighing systems are those which have typical weighment sizes over 50lbs (23kg) to around 100-150lbs (45-65kg). Major weighing systems have individual weighments greater than minor.  It also is not unusual to see a weighing system with micro, minor and major size weighments.  These systems may combine automatic and semi-automatic systems together into a hybrid system, combining multiple weighment sizes and both automatic and manual weighing and batching.

We offer a variety of feeding devices for the minor and major weighing systems that are chosen based upon the best solution for the specific application, through material product feasibility studies. For the screw or auger feeder selection, considerations include: 1) the industry (food, agricultural or industrial), and 2) demands of the application. For industrial applications we offer a Standard Duty design, or Heavy Duty design for different bin sizes and ingredient loads. We also offer Agricultural and Food Grade design feeders for these specific applications. Selection is typically driven by the products bulk density and the environment of the application. Standard feeder designs range from 2 to 6 inches. Size selection is depending upon accuracy and rate requirements. We also offer systems with vibratory feeders. depending upon the application, where screw (auger type) feeders are not appropriate or the best choice.Interstate Mills - Minor System

Scale devices such as hoppers, platforms, conveyors, etc. are used in a variety of designs, depending on the specific requirements of the application. When considering the scale device or type, many application factors are reviewed such as the required scale resolution, accuracy, batch rate and also room constraints.

Transfer of completed batches to downstream processing, such as a mixer, blender or other process equipment, can be done manually (a semi-automatic system) or automatically.

Minor and major weighing systems (a.k.a. minor ingredient systems, minor ingredient batching systems; major ingredient batching systems) are modular in design allowing for expansion of the systems as requirements change over time. Many customers will automate the most frequently used material with the highest volumes and add to the system. Systems typically range from 6 to 48 storage/supply bins, with an average of 24 micro bins. It is not unusual to update systems with additional bins and update system controls decades after initial design and installation.  Sterling Systems & Controls, Inc. minor and major weighing systems (a.k.a. minor ingredient systems or minor ingredient batching systems; major ingredient batching systems) are designed to easily allow for expansion, changes and modifications mechanically as well as in the controls and automation area.

The Sterling Systems & Controls Weighing System shown here features 18 supply bins, 4 scales with batching software for formulations, inventory tolerance control, lot tracking, and corp interface.

Sterling Systems & Controls, Inc. customizes the design and manufacture of minor and major weighing systems (a.k.a. minor ingredient systems or minor ingredient batching systems; major ingredient batching systems) to provide the most efficient weighing and batching systems for various agriculture and industrial applications; including feed, petfood, food, baking, rubber, chemicals and many more industries.

Our unique approach to micro and minor ingredient weighing systems set us apart from typical systems. The designs are customized for each application utilizing standardized components. We offer Bulk Bag Unloading and Weighing Systems, Ridged Tote Bin Systems, Large and small supply bin systems manufactured from Carbon Steel, Stainless Steel and Plastic. The scales designs are customized to minimize mass of the scale to insure high scale resolution while maximize accuracy and repeatability. These system include many features that cannot be found in competitors systems to insure consistent weighments and batch integrity. Robust system designs include multiple pitch feeders, bearings at each end of the feeder, seals and air gaps to insure product is not contaminated by bearing lubricants.
