Rema Opposed Jet Mills

Opposed jet mills are a type of air microniser used for superfine grinding of a wide variety of specialist materials when other types of grinder are unsuitable, particularly in situations where the feed material is hard and where high purity products are required. High energy air jets are introduced through a series of nozzles to grind material down, while an integrated rotary classifier wheel sorts the particles during the process. Our Opposed Jet Mills enable accurate and highly controllable particle sizes to be achieved with sharp cut off and a narrow size distribution. We have a range of sizes designed for throughputs of between 1kg/hr and 2000kg/hr. Find out more about the features and benefits of our opposed jet mills on the British Rema website.

Rema Spiral Flow Jet Mill

Spiral flow jet mills are also a type of air microniser. These are used for grinding hard and soft materials (of up to 10 Mohs) and producing powders in the range of 1 to 20 microns. High energy air jets are introduced through a series of specialist nozzles to create a high-speed vortex within the shallow grinding chamber. After the material is ground through attrition within this vortex, it is drawn through the central fixed classifier. This type of system is typically used for processing pharmaceuticals and speciality chemicals where contamination-free powders are essential. We have a range of sizes available that are capable of handling throughputs of between 1kg/hr and 100kg/hr.

Rema Rotary Impact Mill

Rotary Impact Mills are generally used for less abrasive applications. These simple yet highly versatile high-speed impact grinders are suitable for materials up to 3 Mohs hardness. We have a number of sizes available that are capable of handling throughputs ranging from 5kg/hr to 2 onnes/hr. Rema Rotary Impact Mills benefit from an energy efficient operation, a symmetrical and reversible rotor design for extended life, individually replaceable tool-steel grinding blades, and simple access for cleaning and maintenance.

Rema Aerosplit Classifier

Our high-efficiency air-swept Aerosplit classifiers are used for processing dry particulate materials and are capable of handling large throughputs of up to 10 tonnes per hour. They are designed to operate either in closed-circuit within a conventional milling machine, or as an independent system that incorporates feeder, fan, and product-collection equipment. These forced-vortex units may be
installed in existing air systems with minimal modifications. Rema Aerosplit Classifiers benefit from an excellent sharpness of cut, precise on-stream control of cut-point, low system resistance and low power consumption.

Rema Minisplit Classification System

Minisplit classification systems are ideal for product formulation trials and R&D work prior to full-scale production. They are the smallest of the forced-vortex classifiers, incorporating a feeder, classifier and product collection system. Minisplit systems are capable of providing sharp cuts in the
range of 1 to 75 microns, and are typically found in research laboratories, pharmaceutical pilot environments and fine chemical testing laboratories. The Minisplit system can also be quickly and easily converted into an Opposed Jet Mill System (see above) complete with integral classifier for size reduction.

Rema Unit Air Separator

Rema Unit Air Separators are used for the classification of a wide variety of materials and are the most efficient unit available in terms of kWhr/tonne of product. They are particularly suitable for the removal of small quantities of oversize material and undesirable fines. Though extremely effective as a self-contained stand-alone unit, the Air Separator can also be operated in closed-circuit with a variety of grinding mills. We have a range of high-performance models available that are capable of providing products in the range of 25 to 300 microns. Unit Air Separators also benefit from low power consumption and low operating costs.

Particle Size Reduction

British Rema Ltd designs, manufactures and supplies a wide range of size reduction mills and micronisers which are capable of processing to the most demanding particle size and size-distribution specifications. Our particle size reduction equipment includes: 

• Air Micronisers (Jet Mills) - used for superfine grinding of a wide range of materials.
• Rotary Impact Mills - also known as beater mills. These are typically used for softer materials of up to 3 Mohs hardness.
• Ball Mills - these comprise of a cylindrical shell that slowly rotates around a horizontal axis, using a grinding medium such as ceramic or steel balls to crush the material within.

Mixing & Blending

We also offer a range of mixing, blending, homogenisation and granulation equipment for powder to liquid applications. Whether it’s a standard powder mixer or a custom-built system, British Rema can offer a versatile choice of efficient mixing and blending equipment in numerous industry-standard materials.

All of the products in this category meet the exacting standards of the food, pharmaceutical and speciality chemical industries. Our portfolio includes:

• Rotating Shape Mixers/Blenders (also known as tumbling action mixers/blenders)
• Vertical Cone Blender/Dryers
• Ribbon Blenders
• High Shear Dry Mixers/Wet Granulators
