Even though, HAZEMAG Center Sizers are available for primary or secondary applications, we do not show this in different models or types. The difference is made by the type of used rolls, with or without breaker bar. However, as a rule of thumb it could be said that a primary center sizer starts at a diameter of 1,000 mm, whereas secondary center sizers end at that diameter.

It is very important to find out the correct ring size whether the ring is for you or another person. This measurement enables us to provide you with a perfectly fitting ring. A ring that is so small you cannot get it on – or so big it falls off – can really ruin a big moment! 1) OUR RING SIZER APP Sizers are typically used in applications where the material being crushed has natural fracture plains and lends itself to compression crushing rather than attrition crushing or impact crushing. Coal, salt and phosphates are very common applications where Sizers are specified. They are also very well-suited to crushing applications where the product is found in high clay bands and requires liberation from the clay as well as size reduction. It is the unique feature of a box sizer, that it can grow in both directions (height and width) but can distribute its growth in the main direction (horizontal for a row) unevenly among its children. In our example case, the vertical sizer is supposed to propagate all its height changes to only the text area, not to the button area. This is determined by the proportion parameter when adding a window (or another sizer) to a sizer. It is interpreted as a weight factor, i.e. it can be zero, indicating that the window may not be resized at all, or above zero. If several windows have a value above zero, the value is interpreted relative to the sum of all weight factors of the sizer, so when adding two windows with a value of 1, they will both get resized equally much and each half as much as the sizer owning them. Then what do we do when a column sizer changes its width? This behaviour is controlled by flags (the second parameter of the Add() function): Zero or no flag indicates that the window will preserve it is original size, wxGROW flag (same as wxEXPAND) forces the window to grow with the sizer, and wxSHAPED flag tells the window to change it is size proportionally, preserving original aspect ratio. When wxGROW flag is not used, the item can be aligned within available space. wxALIGN_LEFT, wxALIGN_TOP, wxALIGN_RIGHT, wxALIGN_BOTTOM, wxALIGN_CENTER_HORIZONTAL and wxALIGN_CENTER_VERTICAL do what they say. wxALIGN_CENTRE (same as wxALIGN_CENTER) is defined as (wxALIGN_CENTER_HORIZONTAL | wxALIGN_CENTER_VERTICAL). Default alignment is wxALIGN_LEFT | wxALIGN_TOP. At the first look it appears as if the method of operation of a Center Sizer would be identical to a Double Roll Crusher. It is in fact very close, however, not identical. Still today, customers are not using always the correct terms because of this irritation. By the end of the day, we, as experts, would have to make the decision on which crusher would be the best choice. The operating principle is based on a continuous generation of pressure between two counter – rotating rolls, so that crushing takes place without interruptions in contrast to the intermittent Jaw Crushers. Due to the small number of high teeth big lumps can immerse deep between the rolls and are crushed immediately. The force acting on material is punctual and even not plane as it is typical for Jaw Crushers. The result is a minimization of fine generation. In contrast to a Double Roll Crusher, the basic concept of the Mineral Sizer is the use of two rolls with smaller diameter shafts, because of the operation at a lower rotational speed by a direct high torque drive system. This design produces three major principles which all interact when breaking materials using sizer technology. The unique principles are the three-stage breaking action, the rotating screen effect, and the deep scroll tooth pattern. All sizers are containers, that is, they are used to lay out one dialog item (or several dialog items), which they contain. Such items are sometimes referred to as the children of the sizer. Independent of how the individual sizers lay out their children, all children have certain features in common:

Rotating screen effect

I agree with Alan that sorting is probably more beneficial than sizing but out of any given lot of pellets you may not have nearly as many usable pellets as the lot contains. Some smaller in head size and probably not usable for good accuracy. Some just right. And some oversize. The pellets that are the exact head size as desired would be your first choice for accurate shooting as they have the desired size and are naturally flared at the skirt. For those pellets that may be SLIGHTLY OVERSIZE then POSSIBLY a tapered adjustable sizer could make those pellets shoot as or nearly as accurately as do the best ones from the lot. Having to size the head a great degree would, as Alan notes, make lead flow and change shape noticeably. The question would logically seem to be HOW MUCH (if any) could the pellet could be downsized and not effect accuracy. We are confident in our ability to provide every ring in every size. However, very small or large fittings may take us a little longer to organize, in some cases 3 to 6 weeks.

AS an observation and not to start a dustup or diss anyone, but I've noticed a bit of "analocity" coming from many of the forums not only on airgun forums but also on powder gun forums relating to high accuracy and how to achieve it. Sizers, as represented by the wxSizer class and its descendants in the wxWidgets class hierarchy, have become the method of choice to define the layout of controls in dialogs in wxWidgets because of their ability to create visually appealing dialogs independent of the platform, taking into account the differences in size and style of the individual controls. Pellet skirts are designed to be significantly large than the head of the pellet, and should exceed the groove diameter of the barrel, so that they are compressed slightly (sized) by the chamber on loading.... This insures a perfect seal.... The hollow base and thin skirt of our pellets changes shape drastically on firing, like this.... The next section describes and shows what can be done with sizers. The following sections briefly describe how to program with individual sizer classes. These are JSB Exacts, the two on the left were fired, the two on the right just pushed through the bore.... The exact shape of the skirt after firing depends on many factors, including the pressure, bore fit, pellet alloy, presence of a choke or not, etc.etc…. That is one reason why the BC of any pellet can vary from gun to gun....Another advantage to such a tapered sizer design could be that it would straighten/round bent skirts. The "pusher" that is illustrated in the Robb design (used to seat the pellet to the adjustable depth in the tapered bore) shows a beveled tip that could serve to round bent skirts and this would certainly be helpful if it indeed works as intended. wxGridSizer is a sizer which lays out its children in a two-dimensional table with all table fields having the same size, i.e. the width of each field is the width of the widest child, the height of each field is the height of the tallest child. Weighing and inspecting for deformation is an excellent way to reduce variability...I can reduce group sizes by half just by weighing my powder bullets...I don't mic OD's but I DO measure ogive lengths...maybe measuring pellet lengths might also help. For information about the wxWidgets resource system, which can describe sizer-based dialogs, see the XML Based Resource System (XRC). See also wxSizer, wxBoxSizer, wxStaticBoxSizer, wxGridSizer, wxFlexGridSizer, wxGridBagSizer Pretty much everything reasonable is worth trying, so test it out. I, like Bob, no longer do much sorting - although I sometimes do some in the crappy winter months if I have the time. Sorting for head size gives me the better results than out of the tin, and then weight sorting on top of that is the gold standard in my book - if the shape is the same (from a head size standpoint) and the weight is the same, then we will get the lowest variation in BC that we can expect. I still maintain that this (BC variability) is the key - so many get their ES down to under 1% at the muzzle, but if you test it at the target you will see a much higher number, and BC has to be the majority of that. As BC varies, flight time and wind drift vary even in identical conditions.

One other thing - the sizing listed on most tins, including H&N and JSB, are pretty much meaningless. I sample each new lot with my pellet gauge and note the data on the tins as I get them. The ones I know will shoot poorly get set aside for tuning and testing, or sometime offhand if I have not been shooting that way for a while (a little more variation there is hard to notice ). You can hide controls contained in sizers the same way you would hide any control, using the wxWindow::Show method. However, wxSizer also offers a separate method which can tell the sizer not to consider that control in its size calculations. To hide a window using the sizer, call wxSizer::Show. You must then call Layout on the sizer to force an update. You can reduce variability only so much and then weather or environmental factors take over...or you just flub the shot.wxStaticBoxSizer is a sizer derived from wxBoxSizer but adds a static box around the sizer. Note that this static box has to be created separately.
