The design of the tool used to grind the garbage entering the unit.

Knife. The main element of such systems, as the name implies, are special knives. Their design can be different: triangular blades with sharpening, rotating discs with several blades, etc. Anyway, this option is considered optimal for working with leaves, because. it ensures thorough and uniform processing of such waste. But with solid large branches, knife systems are less compatible; see "Crushing" for details.

Valkovaya. Also, such systems are called milling. Their action is based on the use of gears with large teeth, which, when rotated, “bite off” and crush pieces of the processed material. This allows you to effectively process thick dry branches, besides, the gears themselves draw the debris inside, in fact, providing automatic feeding (see below). But roll systems do not work well with leaves and other “soft” debris. Therefore, models of this design are usually intended purely for branches (see "Chipping").
—
Turbine. Turbine systems use a cutting element in the form of a cylindrical or conical drum with blades located horizontally. Their design is such that the shredder is able to cope equally effectively with both leaves and thick branches (see "Chipping"). The main disadvantage of "turbines" is the high cost.
— Leskovaya. As the name implies, systems of t
...his type use a fishing line that rotates at high speed during operation. They are designed to work exclusively with leaves (see "Crushing"), and it is the leaves that the scaffold unit processes in the best quality. But with other types of garbage — even with thick grassy stems — such shredders can have problems.The largest thickness of debris that the shredder can handle normally. This parameter will allow you to evaluate how a particular device is suitable for a particular situation.
Note that the maximum diameter of the crushed material is important for models that allow working with branches (see "Chipping"). But in specialized aggregates for leaves, it is usually not indicated at all: the thickness of the garbage processed in such grinders is, by definition, small, and creating a design that works normally with any “soft” materials is usually not a problem.
The maximum amount of material that the shredder can process per hour. Note that in this case, the possibilities for perfect conditions are usually indicated: homogeneous garbage fed evenly, no interruptions in work, maximum speed (see “Adjusting the speed of the shredder”), etc. In addition, for universal models (see "Crushing"), the throughput is usually indicated for the most "convenient" material — leaves. Nevertheless, this parameter quite clearly characterizes the performance of the grinder.
It is worth choosing a model for throughput taking into account the volume of the proposed work. At the same time, it does not fit to take a certain margin, but it should not be too large — after all, high performance requires appropriate power, which, in turn, affects the dimensions, weight, price and "voracity" of the unit. Specific recommendations on optimal performance values for different situations can be found in special sources.
