Description

A kind of horizontal drum pulverizer and reducing mechanism thereof

Technical field

The present invention relates to a kind of size reduction machinery and corollary apparatus thereof, more specifically, the present invention relates to a kind of horizontal drum pulverizer and the reducing mechanism of this horizontal drum pulverizer is installed.

Background technology

In comminution process, the overwhelming majority of the energy in input size reduction machinery is all converted into heat and is absorbed by size reduction machinery, circulating air and pulverized material etc., and the amount be directly used on crushing material is but minimum; In crushing mechanism, be generally no more than 10%; In grinding machine, then normal less than 1%; Therefore, in order to reduce energy consumption, just must choose suitable size reduction machinery, adopting correct method of operating, the comminution ratio of regulation the best and the output in the unit interval.

In the grinding of ore and the grinding process of composite fertilizer's returning charge particle, conventional grinding machine has ball (rod) grinding machine, squirrel cage crasher, horizontal chain breaker, vertical chain breaker, hammer roll crusher, Multi-roller extruding disintegrating machine.

Do not produce dirt in ball (rod) grinding machine wet-milling process, produce dirt in dry milled process few, but cost is high, the power consumption of ton product is high.

Squirrel cage crasher is not easy for the grinding of the higher glutinous wet stock of water content and easy moisture absorption material, and in grinding process, produce dirt many, need the supporting dedusting with it of multistage cleaner, squirrel cage crasher and supporting dust pelletizing system cost high, big for environment pollution.

Horizontal chain breaker and vertical chain breaker are applicable to the grinding of the higher glutinous wet stock of water content and the easy material that moisture absorption compression strength is low, are unsuitable for the grinding of the high material of compression strength; Because the time of material in its device crushing process is shorter, on average only have between 0.2 second ~ 0.6 second, crushing effect is poor, and crush efficiency is low.

Hammer roll crusher is suitable for the pulverizing of middle hard material, and crushing effect is better, but produces in crushing process that dirt is many, crush efficiency is low, and equipment manufacturing cost is high, and power consumption is large.

The pulverizing of hard and rigid material during Multi-roller extruding disintegrating machine is suitable for, crushing rear material is random fine granularity, and crushing effect is better, produce dirt in crushing process few, but crush efficiency is low, equipment manufacturing cost is high, power consumption is large, and the material after pulverizing is unsuitable for the granulation process of rounded grain composite fertilizer.

Such as Chinese patent CN202506438U discloses horizontal revolving drum from clear pulverizer, comprise the main shaft (7) installed in horizontally-mounted housing and housing, it is characterized in that: housing divides for the two parts be set with by rear head (3) and cylindrical shell (5), main shaft (7) by bearing and bearing block (2) eccentric be arranged on bottom in housing, reducing mechanism installed by main shaft (7), cylindrical shell (5) side connects the first motor (15) by geared system and transmission device, main shaft (7) one end connects another motor by transmission device.This technical scheme scraper that side is arranged in cylindrical shell can be used to carry out secondary cleaning to cylinder inboard wall and uses; clear up the material remained on cylindrical shell, stop the wall sticking phenomenon of material, reduce the Stickiness of material further; ensure good crushing effect, eliminate the loaded down with trivial details of maintenance shut-downs.

Such as application number is the Chinese patent of 02208800.8 again, just describes one and scrapes wall type chain crusher, wherein, abrasive material loop chain and scraper are all fixing on the driving shaft by support installing, scraper symmetry is installed, the contiguous cylinder inboard wall face of cutting edge, and is provided with certain angle with wall.Although this technology also can play certain cleaning effect to the inwall of pulverizer, but its general structure more complicated, volume is comparatively large, heavier mass, narrow application range, and the same power source adopted, need the motor being equipped with relatively high power, scrape wall and must carry out simultaneously with pulverizing, influence each other, operational effect is undesirable.

Above equipment because material volume weight (mixture of material and the air) moment that is little, that impact material contacted in crushing process is little, that single pulverizes comminution ratio is not good etc. on the one hand or the reason of several respects, cause crushing process medium power consume high, crushing effect is poor or poor, that crush efficiency is low problem.
