Sample Splitters

Precision Riffle splitters with controlled sample discharge

Available with 3 mm to 20 mm slots width, specified by the client or selected from recommended standard sizes. Standard sizes conform to the Australian Standard AS 1141.2-1999 & ISO 3082:1998(E)

The splitters are separable. The slots width and quantity can be adjusted to suit laboratory requirement. Design of the slot protecting lining is covered by Patent N°2010100147.

Splitters are made from Stainless Steel with an electro polishing finish. They are suitable for Food, Pharmaceutical and Geotechnical laboratories.

Splitters feature two dust hoods to minimise dust pollution when operated and a swivelled carrying handle. The swivelled handle provides for extra comfort when shifting the unit around the premises.

The dust hoods are conveniently hinged and allow for easy inspection of the riffles to check for blockages. By lifting the dust hood the operator has clear access to quickly rectify this type of problem.

Available Configurations:

Number of Slots	30	16	34	12	30	16	12	16	16
Slot Size, mm	3	6	6	7	7	10	13	13	20

Below is the splitting ratio test of the 16 x 13 mm Precision Riffle Splitter, conducted at Sibelco Australia Limited, South Australia. The testing personnel filled the hopper and proceeded to weigh the material from 3 splits of progressively less material. The results are as follow:

	Left tray (g)	Right tray (g)	Total (g)	% Left Tray	% Right Tray
Split 1	3047	3059	6106	49.90	50.10
Split 2	1527	1530	3057	49.95	50.05
Split 3	764	765	1529	49.97	50.03

Laboratory Riffle Splitters welded. (Slot Width from 7 mm to 13 mm)

Main features of the splitters are:

• Deep loading bunker which eliminates accidental spillage of the sample over the side of the splitter.
  
  
• Does not require special trays to contain samples. In fact, most of the containers purchased off the shelf will do the job.
  
  
• One support frame will fit for a range of splitters.
  
  
• The size of the unit is convenient for handling. In other words it is not too small as to be uncomfortable to work with.
  
  
• The splitter is made of Stainless Steel SS-316, with electro polish finish. The support frame is made of aluminium plate, with powder coat finish.
  
  

  The support frame can be made out of Stainless Steel if required.

  The unit is perfect to use when it comes to split small batches of different material samples.

  Optional features:

  1. Dust hood can be incorporated into design upon request.
  2. Special purposes trays are available.

  
  

Large Riffle Splitters. (20 mm to 60 mm slot width)

Main features of the splitters are:

• Dust hood and fully covered receiving trays eliminate the excessive dust pollution when operated.
  
  
• Special provision is made in the design to handle tipping over heavy loads, hence increasing the accuracy of the split.
  
  
• Supplied with three trays.
  
  
• Removable dividing head. Once the head is worn out it can be replaced without the need to buy a whole Riffle Splitter anew.
  
  
• One support frame will fit for a range of splitters.
  
  
• The sizes of the slots for different dividing heads are conforming to
  ISO 3082:1998(E) Standard.
  
  
• The splitter is made of Stainless Steel SS-316, with electro polish finish. The support frame is made of Mild Steel, with powder coat finish.

  The support frame can be made out of Stainless Steel if required.

Two-Tiered Riffle Splitter

• A ME&QC exclusive, this two-tier splitter is designed and built for use in the field or in the lab.
  Ideal for drilling projects where large quantities or big samples need to be reduced in size quickly.

• The front dust hood is hinged. That allows for easy inspection of the riffles. It is although convenient in case of riffles are getting blocked. By lifting the hood operator gets clear access to the riffles. That makes rectifying a problem and cleaning between samples a snap.

• Standard configuration of the splitting heads is 14 x 30 mm. The width and quantity of the slots can be specified by a customer. Available slot widths are 20mm, 25mm, 30mm and 35mm.

 

• The riffle splitter is made out of Stainless Steel with electro polishing finish. Suitable for Food, Pharmaceutical, Geotechnical laboratories and field work.

Three-Tiered Riffle Splitter

• A ME&QC exclusive, this three-tiered splitter is designed and built for use in the sample processing shops at mine sites or analytical laboratories. Ideal for projects where large quantities or big samples need to be reduced in size quickly.
  

 

 

 

• The splitter is fitted with three hoppers with double trap door (opening symmetrically) for each one. That allows much more control in sample splitting process. From the test work the weight distribution between sample and reject is pretty well spot on i.e., 87.5:12.5

 

 

 

• The capacity of upper hopper is 20 Litres. Standard configuration of the splitting heads is 18 x 31.8mm. The width and quantity of the slots can be altered by a customer request. Available slot widths are 19.05mm, 25.4mm, 38.1mm.
