Mid-Point Test Sieves |
 |
|
What Is A Mid-Point Sieve?
A mid-point test sieve has had the mesh inspected. The sieve is then selected as a mid-point if the results give tolerances that are in the middle of the ASTM Standard. For example, the ASTM permissible variations for the mesh of a No. 40 sieve (425μ) are:
1:Average Opening ±19μ.
2:Opening Dimension of 396μ not exceeded by more than 5% of the openings.
3:maximum individual opening 502μ.
The mid-point would have a variation in Average Opening of ±9.5μ, opening dimension of 396μ not exceeded by more than 2.5% of the openings and a maximum individual opening of 463.5μ. The effect of this tightened tolerance is an improvement in variation of approximately 30%. These results are traceable to a NIST standard.
Where Should Mid-Point Sieves Be Used?
When a process requires a high level of repeatability, mid-points can be used on all sieve tests. However, the predominant application for the mid-point sieves is as master stack. A master stack is used to check and recalibrate sieves used in everyday testing.
Summary
If your process must have traceability and the precision and repeatability of your sieve testing results is critical to your process or customer requirements, Mid-Point sieves should be considered for the master stacks and for every day testing of supercritical processes.

Working Sieves |
|
|
What Do We Mean By Working Sieves?
Because we carry high precision Mid-Point and Mesh Certified Test Sieves (MCTS) we need to make a distinction between them and the work-horse sieves used day to day. These sieves that do not require special inspection but need to conform to the basic standards of ASTM E-11, we call Working Sieves. The Working Sieves are available in Brass frames with brass or Stainless Steel mesh. We also supply stainless steel frames with stainless steel mesh. Working Sieves are available with 8 inch and 12 inch diameter frames. The frames are full height and one half height depths.
These sieves are constructed using ASTM standard wire cloth (mesh) and are supplied with a Certificate of Conformance. The mesh has not been individually inspected. Each sieve has a serial number which is related to a lot number.
Working Sieves are used in a diverse range of industries that include construction, mining, food, soil testing pharmaceuticals. They can be checked against master stacks, master samples or calibration spheres (beads) to test for wear or mesh damage.
There are no more economical and practical sieves for everyday use where extra tight and traceable standards are not required.
Summary
These Working Sieves are the intelligent choice for the application that has a limited requirement for traceability but needs a work horse sieve to perform on test after test.

|
|
Spiral Wire Belts are used through a variety of industries from food processing to heat treatment. Wire belt patterns include: Balance, Compound, Duplex, Chain Driven, Baking Bands, etc.
Spiral wire belting makes the premier material for the major conveyor applications.
Wire conveyor belt is made of various metals which will withstand both atmospheric and chemical corrosion, or of any alloy which will resist heat treating furnace temperatures. To eliminate any danger of product contamination, stainless steel wire belts are recommended.
Balanced Spiral Wire Belts:
Balanced Spiral Belts are the most widely used of all our belts being suitable for a wide range of applications. The construction of the belt gives minimal contact with article being conveyed; resists stretching and contraction thus having longer life; true running; allows free air-flow; temperature tolerant.
Uses: Balanced spiral wire belts is suitable for washing, drying baking or heating and cooling operations. Also for glass annealing.
Flat Spiral Wire Belts:
The close mesh and the smooth flat surface of the Flat Spiral Belt make it ideal for general conveying of a wide nature where good drainage is not required. Its high tensile strength makes it particularly suitable for high temperature work.
Uses: This kind of spiral wire belts are for side feeding, ploughing off, feeding industrial furnaces.
Balanced Wire Belt:
Balanced wire belt featuring crimped wire construction makes the economical belt with high tensile strength and minimal tendency to creep to either side on the drive pulley.
Industries served:
Food Industry – Conveying, washing, blanching, drying, frying, freezing, baking, cooling, wrapping, packing, canning, bottling etc..
Heat Treatment - Brazing, bluing, hardening, washing, degreasing, pickling, sintering, quenching, rinsing, tempering, drawing, enameling, etc.
Ceramics and Glass Industries - Annealing, decorating, sanding etc.

Woven Wire Belt |
|
|
Woven wire belt is constructed of individual wires mounted on cross rods which can be driven by side chains and sprockets. The aperture size can be altered by fitting washers or spacing pieces. The construction allows for easy cleaning, is virtually non-clogging and has a smooth even top surface allowing articles to move freely.
Compound close mesh woven wire belt has close mesh, firm belt and high tensile strength.
This type of woven wire belting can use the thickest wire diameter and provides the highest tension. Smooth belt surface is appropriate for transferring unstable items. The parts of highest strength can be used for reinforcing the edge and a net-type flange can be easily installed.
Features and uses:
These wire belts are made up of very close meshes and smooth flat surfaces, making them ideal for carrying very fine or small articles and especially suitable for supporting unstable items.
Applications include:
Conveying of biscuits, cereals, chemicals, glassware, electrical components, continuous baking direct on the belt.

Flat wire conveyor belts offer a flat conveying surface and a maximum open area for free air flow or water drainage. They are easy to clean and are extremely sanitary, especially when manufactured with Ashworth-recommended clinched edges. Clinched-edge treatment of these belts results in a number of additional user benefits which are fully outlined in the product technical bulletin.
All welded selvage belts over 24 inches in width feature the resistance welding of every other connector rod to the flat strip on the 2nd opening in from each edge of the belt. On true 1/2" x 1/2" mesh belts this weld is on every 3rd connector rod. This provides for greater strength and eliminates belt shrinkage under heavy loads without restricting flexibility of the belt. Upon special request, belts 24" and under can be supplied with internal welds.
Flat wire conveyor belts Materials available:
Galvanized Low Carbon Steel (C1015).
Bright High Carbon Steel (C1045).
