Sizers process many different materials

Whether it is primary, secondary or tertiary crushing, dump fed or metered, our sturdy, versatile Sizers have been expertly designed to handle many different materials and throughput capacities. Not only are Sizers insensitive to soft, wet and sticky material, but they can also process hard, abrasive rock either separately or combined.

Sizer Range

MMD Sizers are tailored to each application to provide the best operation and cater to all your requirements.

400mm Overall Height

The 200 and 350 Series Sizers are our smallest machines we produce. They are designed for processing lower tonnages and producing smaller product sizes.

Tooth configurations vary depending on the material type, infeed size and outfeed size. 

Dimensions and weights shown are typical, and may vary dependant upon configuration.

615mm Height

1870m Width

12 Tonnes Weight

The 500 Series Sizer was the first designed in the MMD range and has been successful in ­numerous industries worldwide. It is one of the most versatile machines, and can be supplied as a primary, secondary or tertiary machine ­depending on the tooth configuration.

This machine can be constructed as a fixed centres, adjustable centres or as a single rotor unit with a range of tooth configurations to suit individual applications.

Dimensions and weights shown are typical, and may vary dependant upon configuration.

770mm Height

2090mm Width

26 Tonnes Weight

The 625 Series Sizer is one of the most popular machines as it can be configured for primary or secondary use in the same system on medium tonnages, allowing common drives for both primary and secondary units.

The length of the inlet can be adjusted at the design stage to suit the tonnage required and can be constructed as a fixed or adjustable centres unit. A wide range of existing tooth configurations are available for this machine to cover most applications.

Dimensions and weights shown are typical, and may vary dependant upon configuration.

1330mm Height

2400mm Width

40 Tonnes Weight

The 750 Series Sizer was developed shortly after the 500 to provide a range of higher tonnage machines capable of breaking larger and harder materials. These machines can be used as a primary or secondary machine depending on the tooth configuration.

When used as a Primary in a process system, it is often paired with a 625 Series secondary to provide a higher reduction ratio than is possible with a single machine. In common with all other MMD Sizers, the inlet size can be tailored to suit the tonnage required.

Dimensions and weights shown are typical, and may vary dependant upon configuration.

1590mm Height

3020mm Width

60 Tonnes Weight

The 1000 Series Sizer was designed to provide a range of primary machines between the 750 and the high tonnage 1300 series. The extra centre distance allows it to cope with a larger infeed size, increasing the capacity considerably for the same inlet length, which can be varied.

This machine is often paired with a 750 series secondary when a multi machine system is necessary to achieve the final product requirements. These units can be fitted with single or double drives of varying powers, using the extensive range of purpose designed MMD gearboxes.

Dimensions and weights shown are typical, and may vary dependant upon configuration.

1845mm Height

3600mm Width

95 Tonnes Weight

The 1300 Series Sizer was developed initially for high tonnage overburden operations as a key component in the change to short haul truck and shovel operations feeding conveyor systems. As overburden by its very nature constantly changes, these machines, in common with the complete range of MMD Sizers, can work on a vast range of materials from wet sticky clay to hard abrasive granites, making them ideal for this type of application.

These machines have since been utilised in many other types of application all over the world. The 1300 Sizer is normally fitted with double drives of varying powers, ­depending on the application.

Dimensions and weights shown are typical, and may vary dependant upon configuration.

2195mm Height

4250 Width

160 Tonnes Weight

The 1500 series Sizer was first supplied to operate within the oil sands industry in Northern Canada to facilitate the switch to short haul truck and shovel extraction, which proved to be a significant economic improvement over the traditional systems previously employed.

The 1500 series Sizer is presently the highest capacity unit available, but design studies are underway for higher tonnage capable Sizers in the future. The high reliability, low wear and low maintenance costs are always key features in any mining operation, but are crucial in this abrasive, hostile environment, where the operation runs 24 hours per day. Varying the inlet length allows changes in capacity to suit the application.
