Problems solved by technology

Therefore, for plastic materials (such as plastics, etc.), since they are easily deformed when processed, it is difficult to cut them into pieces by the cutting method of the above-mentioned line contact.
Therefore, the above-mentioned wire cutting method makes the existing mills only able to process brittle materials, such as ore, slag, coal, beans, etc., but not easy to process easily deformable plast

Example Embodiment

[0030] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and the embodiments.

[0031] Such as figure 1 As shown, the pulverizer according to the embodiment of the present invention mainly includes a feeding mechanism 5, a grinding mechanism 2 arranged under the feeding mechanism 5, a screening mechanism 3 arranged under the grinding mechanism 2, a supporting mechanism 4, The semi-coarse material sieved by the sieving mechanism 3 is automatically sent back to the return mechanism 1 of the feeding mechanism 5, and a detachable adjusting member 6 for adjusting the gap of the grinding zone.

[0032] Wherein, the feeding mechanism 5 includes a hopper 51 which is located above the grinding mechanism 2. In the grinding mechanism 2, the motor 21 drives the pinion gear 27 through the lower reducer 28, and the pinion gear 27 meshes with the large gear 22. The large gear 22 is fixed to the revolving cylinder 23 underneath by screws, an...

Abstract

The invention provides a grain mill, which comprises a grinding mechanism (2), wherein the grinding mechanism (2) comprises a fixed mill (26) and a rotary mill (25); the fixed mill (26) and the rotary mill (25) are provided with a grinding tooth set consisting of grinding teeth respectively; each grinding tooth comprises a first toothed side face, a second toothed side face and a toothed top surface between the first and second toothed side faces; and the toothed top surface of the grinding tooth of the fixed mill is matched with the toothed top surface of the grinding tooth of the rotary mill. The grain mill effectively changes the line contact between the grinding teeth of the prior art into the surface contact so as to greatly improve the grinding effect, and particularly, the grain mill of the invention can not only be suitable for the fragile material but also have the capacity of grinding the deformable plastic material.

Description

technical field [0001] The invention relates to material grinding and processing equipment, and more specifically relates to a multifunctional mill capable of grinding not only brittle materials but also plastic materials. Background technique [0002] Mills are widely used in the grinding and processing of materials (such as ores, waste plastic materials, etc.) in the fields of building materials, metallurgy, chemicals, mining, food, waste recycling, etc. [0003] In existing mills, there is generally a line contact between the fixed mill and the rotary mill. Specifically, the grinding teeth of the existing pulverizer are composed of two side tooth surfaces. During grinding, the material is cut through the intersection line formed by the intersection of the two side tooth surfaces; and, in the existing pulverizer, All grinding teeth extend in the same direction on both fixed and rotary grinding. Therefore, for plastic materials (such as plastics, etc.), since they are eas...
