Raymond roller mills are available with grinding ring diameters ranging from 30 inches to 86 inches (760 to 2180mm). Typical production rates are shown in the table above. These available sizes are capable of producing a wide range of product finenesses from a wide variety of materials.
Practically all naturally occurring nonmetallic minerals and many manufactured products contain a certain amount of free moisture. At one time it was necessary to dry these products in an independent system. The technique used by Raymond combines drying and pulverizing in the roller mill. This may make it possible to eliminate independent drying equipment reducing capital investmet, processing time and handling.
Heated air or waste gas is delivered to the Raymond Mill return air housing and introduced
through air ports to the grinding zone in the mill. The air turbulence and particle size produced during the grinding process are ideal for almost instantaneous evaporation of moisture.
Feed moisture is normally limited to what can be reliably fed into the mill. Typical product moistures are 0.1 to 0.5% by weight.
Raymond offers the following to compliment the roller mill system:
- • pilot plant material testing
- • premium wear parts
- • PLC-based control systems
- • field service support

Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
