Sizers

In 1978 Ansec Sizers first created the A200 Mini Sizer, a compact single shaft Mineral Sizer, mainly for use in the British Coal Board era for underground crushing. Their compact size incorporated a robust design which led to sales in the hundreds for use across British Coal Mines.

 

Ansec further developed from this, progressing up to the A550 Twin Roll Sizers for larger tonnages in excess of 1000 tonnes per hour.

The aquisition of Ansec Sizers by Derek Parnaby Cyclones in 2005 has seen a significant improvement and development on top of an already successful design.

Ansec A550 Mineral Sizer:

The Ansec A550 series of mineral sizers have been developed from the highly successful A200 single roll and A500 twin roll sizers.

Considerable research and development coupled with extensive field trials have helped to produce machines which can accurately size material with very low increase in the quantities of ‘fines’, this leading to increased efficiency in the transportation of materials by effectively eliminating the problem caused by large lumps of material.

The machines are of simple yet extremely robust construction, giving efficient operation with minimum operating costs and maintenance.

Materials up to 28,000 to 30,000 psi compressive strength can be effectively processed by these machines.

Throughputs of up to 2,500 tonne/hour have been achieved, but the actual throughput of a specific machine will depend on the material being processed, infeed size and the sizing requirements.

On-Pan Breaker:

The Ansec two stage on-pan sizer was developed for heavy sizing work with large infeed size requiring a product size of less than 250 mm. So often the limiting factor with on-pan breakers
is the height to drum centre which determines the maximum lump size entering the machine. The primary stage on the Ansec machine can be set independently to grab the large pieces, whilst the second stage can be set to obtain the required product size.

A200 Series Mineral Sizers:

The A200 series of mineral sizers were developed to meet the needs of mining today. Reductions in manpower and increased efficiency through its simple robust design give good value for money.

Material up to 28000 psi can be processed thru the A200 machines which use a variety of pick designs from the basic carbide tips point attack to the purpose designed cast manganese steel teeth for special applications.

Considerable research and development coupled with extensive field trials have helped to produce machines which can size accurately with very low increase in ‘fines’.

The feature of the machines is the ease with which adjustment of sized product is achieved (especially important in the smaller size product). Maintenance is simplicity itself with teeth being individually changed if required reducing down time and cost to a minimum.

Extensive trials with British Coal’s test establishment and site operations have led to national approval both for underground use and coal preparation plants.

The Ansec A200 Mineral Sizer is a pour through machine designed for throughputs from 30 tonnes per hour to 1800 tonnes per hour. Product sizing is in the range

Throughputs depend on material and size required.
