key word:Heat exchange element


Product description

JLX series Toothed Screw Frozen Coal Unloader

 

1. Introduction

1.1. Purpose

JLX series toothed screw frozen coal unloader is a new type of frozen coal unloading equipment developed on the basis of the screw unloader. It has the ability to break large pieces of coal and frozen coal. It is the ideal product of the Northern Power Plant's winter coal unloading equipment and the only mechanical frozen coal unloading equipment in China.

1.2. Model meaning

JLX-****

JLX pick screw frozen coal unloading machine

1.3. Structure features of working principle

JLX toothed screw frozen coal unloader is composed of traveling mechanism, lifting mechanism, rotating mechanism and moving beam mechanism. Its screw adopts cone-shaped screw, and the pick mechanism for mining coal is installed on the spiral blade to complete its special functions. Its spiral lifting mechanism adopts vertical feed mode to achieve the work. In order to meet the requirements of crushing large coal and frozen coal, the carbide cutter head on the milling disc of mining machinery with equal distance is installed on the spiral blade, and the vertical feed motion and the spiral body rotation motion are used.
