RGMTSI has a wide variety of blenders for contract toll blending and powder mixing. Thus allowing us to handle almost any type of material across multiple industries. Combine your dry ingredients to a precise ratio and achieve a homogeneous mixture. Both chemical blending and chemical mixing combine different ingredients. Another difference is the chemical blending is more often associated with combining two solids or a solid and a small amount of liquid, whereas chemical mixing more commonly combines two liquids or liquids and gases.
