Abstract

The utility model discloses a material pulverizer which comprises a housing, wherein an inverted-frustum-shaped rotating body and an inverted-frustum-shaped filtration supporting piece are arranged in the housing; the rotating body is movably connected with the housing through a main shaft; fixed blades and movable blades are distributed on the circumferential side of the rotating body; the filtration supporting piece is fixedly connected with the housing; a funnel-type slag blanking hopper communicated with the filtration supporting piece is arranged at the bottom of the housing; a material inlet and a slag inlet are respectively formed in the top of the housing; the slag blanking hopper is communicated with the slag inlet through a material returning pipe; a finished product outlet is formed in the lower part of the side wall of the housing. Finished product pulverized materials meeting a requirement are filtered into a cavity formed between the filtration supporting piece and the housing, and the phenomenon that the finished product pulverized materials meeting the requirement and slag which does not meet the requirement return at the same time is avoided; equipment and unnecessary work of people are reduced; the equipment resistance is alleviated, and the equipment efficiency is improved; an overall material down channel is in a state of gradually narrowing and tightening, so that the materials subjected to a certain pulverizing process can still keep certain compactness when moving to a clearance in the lower part, and the materials at the lower part can be efficiently and fully pulverized.

Description

Materials crusher

Technical field

The utility model relates to crushing material equipment technical field, relates in particular to a kind of materials crusher.

Background technology

At present, pulverizer traditional on market is owing to mostly being horizontal pulverizer, and lack thickness material separating mechanism, in actual applications, due to material, conventionally once pulverize and be difficult to completely qualifiedly, need feed back repeatedly to repeat to pulverize, tradition pulverizer need to repeat whole materials to pulverize, so just increased personnel and equipment workload, time-consuming efficiency is low, and power consumption is high; Or vigorous property material larger for some water content particularly, situation is even more serious, often occurs in actual applications the blocked and situations such as machine of choking of screen cloth, and material difficulty or ease are pulverized, and easily cause equipment downtime, even damage equipment; This class material does not reach crushing effect with jaw crusher or edge runner at all, and material can be pressed into mud cake shape, adopts beater grinder easily to cause material to be bonded on fixed disk, and stall is shut down.

The utility model patent that on March 20th, 2013, disclosed application number was 201210456393.8 discloses a kind of continuous vertical and has stirred pulverizer, mainly by decelerator, shaft coupling, upper bearing (metal), lower bearing, shaft, cylindrical shell, blade fixed disk, revolving vane, fixed blades and elastic shock-absorbing device form, upper on cylindrical shell, shaft is installed in lower bearing and with shaft coupling, is fixedly mounted decelerator or hydraulic motor in the overhanging upper end section of shaft, the cylinder inner segment of this shaft is regular polygon shaft part, on the regular polygon shaft part of this shaft, suit blade fixed disk is fixed in uniform compartment of terrain from top to bottom, uniform fixed installation revolving vane on the regular polygon dish of each blade fixed disk, on the inwall of cylindrical shell, fixedly mount abrasion-proof backing block, the fixed blades of compartment of terrain circumference uniform distribution fixed installation from top to bottom on the inwall of cylindrical shell, the relative motion of revolving vane and fixed blades, make material reach the effect being uniformly mixed when pulverizing.

Its weak point is: 1) lack thickness feed separation mechanism, while carrying out feed back pulverizing for the disposable material that is difficult to pulverize, repeat to pulverize qualified material, cause facility load to increase the weight of, personnel's workload increases, and affecting operating efficiency and power consumption increases; 2) cylindrical tube body structure, easily causes material to decline too fast, the abundant comminuting matter of difficulty or ease.
