Manufacturers use toll blending services when they need consistent, repeatable blends without taking on the cost and complexity of running blending operations internally. Materials behave differently depending on particle size, density, moisture and formulation. Getting a blend right is rarely just turning on a mixer and walking away. It takes the right equipment, controlled batch sizes and an expert understanding of how materials interact during mixing.
Custom Blending Services from M&M Milling
Toll blending solutions allow a company to outsource the blending step of its production process to a third party facility. You supply the raw materials and specifications. The toll blender handles the blending operation, quality checks and batch execution.
This model is often used when in house equipment is undersized, fully utilized, or not designed for a specific formulation. It is also common for seasonal production, new product launches or materials that require tighter process control than existing systems can provide. For dry powders and granular products, a proper toll blending process helps reduce segregation, improve uniformity, and maintain consistency from batch to batch.
A good chemical blending setup should scale with your needs without forcing you into permanent equipment decisions.
Dry Powder Blending
Dry powder blending involves combining powders or granulated materials into a uniform mixture at a defined ratio. While the concept is simple, the execution is not. Differences in particle size, bulk density, and flow characteristics can cause separation during mixing or discharge if the process is not properly controlled.
Effective dry blending focuses on mixing method, batch size, fill level, and discharge handling. These details matter more than most people expect. Small adjustments can change blend uniformity significantly, especially with fine powders or low inclusion additives. Toll blending services are often used to manage these variables consistently, particularly when internal processes struggle to maintain repeatable results.
Our Industrial Blending Equipment
At M&M Milling, we invest in precision blending machinery that is capable of accurately measuring and mixing ingredients to meet your exact specifications. Our equipment is designed to ensure thorough blending and uniform distribution of ingredients, resulting in consistent and high quality blends every time.
Ribbon Blenders
Ribbon blenders use internal ribbons to mix dry powders and granular materials within a controlled batch size.
Rotary Blenders
Rotary blenders mix material through vessel rotation and are typically used when a gentler blending action is preferred.

Toll Blending Solutions for Every Industry
M&M Milling’s toll manufacturing services cater to many industries, providing blending solutions to meet specific needs and requirements. Explore all industries >
Agriculture and Animal Feed
Custom fertilizer blends, mineral mixes and animal feed formulations often require consistent ratios and uniform distribution of nutrients. Toll blending allows producers to adjust formulations without reconfiguring internal equipment.
Chemical and Specialty Chemical
Chemical manufacturing can rely on our chemical blending services to create custom formulations for a wide range of applications. When blending specialty chemicals for industrial processes, we always provide flexible and efficient blending solutions.
Soil Amendment and Remediation
Soil blends and remediation materials often combine components with different densities and flow properties. Toll blending supports consistent output for project based or variable production volumes.
Specialty Materials and Additives
Industries such as battery manufacturing and mineral processing use toll blending for additives and functional materials that affect downstream processing and product performance.
Planning a Toll Blending Project
A toll blending project usually runs smoother when specifications are defined early and kept practical. Several inputs influence how the blending process behaves especially for chemical blending and other dry powder applications common in industrial and powder processing.
These factors are often reviewed before production begins:
- Material properties
- Target ratios
- Batch sizes
- Moisture content
- Particle size spread
- Bulk density
Details in these areas can affect blend uniformity more than expected so addressing them up front helps avoid rework.
Toll blending manufacturing is often used when production demand changes or when internal equipment is not suited for a particular formulation. Projects may involve short runs or large scale production. Packaging services and bulk material handling should be considered early in the process as well.
