JAW CRUSHER

使用说明书OPERATING INSTRUCTION

一、用途

I. Application:

本破碎机用于粗碎、中碎抗压强度极限不超过245MPa的各种岩石或矿石。

The crusher is applicable for the rough and medium crushing of rocks and ores that have a compressive strength not more than 245MPa.

二、主要技术性能

三、结构简述

III. Structure

本机主要由机架、动颚、偏心轴、颚板、肘板等零部件组成。电动机通过三角皮带传动偏心轴旋转，使动颚按照已调好的轨迹进行运动，从而将破碎腔内物料予以破碎。

The equipment consists of bracket, jaw, eccentric shaft, jaw plate and ancon plate etc. Eccentric shaft is driven to rotate by motor and jaw runs on adjusted track to crush materials in crushing chamber.

机架系优质铸钢结构，机架前壁上装有楔形螺栓紧固的固定颚板。在破碎机左右的机

架内侧壁上装有边护板，以保护机架内侧壁的磨损。

The bracket is high quality cast steel structure. On the front arm of bracket, jaw plate is fixed by wedge-shaped bolt. Edge protection plate is equipped on inside wall of bracket to prevent abrasion.

颚为一成型铸钢件，正面装有活动颚板，其上部借偏心轴与滚柱轴承悬挂在机架上、下部支承在肘板上，并与肘板成滚动接触，在偏心轴两端装有飞轮和槽轮。

The jaw is a shaped casting with a kinetic jaw plate on the face. The upper part of jaw is hung on upper and lower parts of bracket and supported on ancon plate by eccentric shaft and roller bearing. There equipped flywheel and grooved pulley at both ends of eccentric shaft.

肘板的另一端支承于调整横梁上并与其成滚动接触。肘板除对动颚起支承作用外，在外来不能破碎的异物，进入破碎腔内时，破碎机负荷物增加的情况下，起保险作用，既自身断裂，从而保护其它机件不变损伤。

The other end of ancon plate is supported on adjusting beam. Besides supporting jaw, the ancon plate plays the role of insurance during load increase caused by the uncrushed material’s entry into crushing chamber. It will be broken to protect other pieces from damage.

调整横梁与机架侧墙电焊钢连接，当排料口调小时，首先放松拉杆弹簧和拉紧螺丝，然后用扳手旋转止动螺钉，使止动螺钉向前顶起垫片组，再插入新增加的垫片，直至所要求的排料口尺寸时，先退回止动螺钉，使垫片组由动颚部件重量压紧，再旋紧拉紧螺钉并紧固定。最后适当旋紧拉杆弹簧，反之则由小变大（抽掉垫片）。

Adjusting beam is welded to side wall of bracket. When the discharge door is adjusted smaller, release tie spring and tightens screw, rotate retention screw to make gasket up, insert new gasket to achieve required size of discharge door, turn back retention screw to make jaw press closely the gaskets, rotate staybolt and fix it and at last, rotate tie spring tight. Conversely, from small size to large one (draw gasket out).

四、安装说明IV. Installation

本机由制造厂装配后整机供应的，用户收到产品后就检查，以便消除在运输过程中可能产生的弊病。

The equipment after assembly is provided by manufacturer and check shall be carried out as soon as receiving product in order to avoid possible troubles during transportation.

1、由于本机工作时振动较大，故建议将机器装在混凝土基础上，为减少振动、噪音和吸振以免机器工作时振动影响建筑基础，最好在破碎机和混凝土基础中间垫以硬木垫板、夹布桐胶带或其它缓冲材料。

1. It is suggested to install the equipment on concrete base to decrease vibration, noise and absorption of shock in order to avoid impact on building base. Adding ironwood, rubber belt or other buffer materials may as well.

2、基础的重量，大致可取为机器重量的5-10倍，地基的深度要大于该处土地冻结的深度，关于机器的安装及地脚螺栓的位置，可参阅基础图。

2. Weight of base can be determined at 5-10 times of that of equipment and the depth of base shall be more than that of local frozen earth. Refer to the Base figure for locations of installing equipment and foundation bolt.

3、在调整排料口前，应先松开拉紧弹簧，待调整好后，再适当调整弹簧的张紧度，以防肘板在工作时脱落。

3. Before adjusting discharge door, release strain spring, and then adjust spring in order to prevent drop of ancon plate.

五、使用须知

V. Notes for use

(一)启动前的准备工作：(I) Preparations before start

1、为仔细检查轴承的润滑情况是否良好，轴承内及肘板的联接处是否有足够的润滑脂。

2、仔细检查所有的紧固是否紧固。

3、传动皮带是否良好，发现皮带有破损现象，应及时更换，当皮带和皮带轮上有油污时，应用干净抹布将其擦净。

1. Check lubrication of bearings and guarantee adequate lubricant inside bearings and on joint of ancon.

2. Check carefully all tightness.

3. Change the abraded belt and clean the oil stain on belt and belt pulley with clean duster cloth.

4、防护装置是否良好，如发现不安全现象，应立即消除之。

5、检查破碎腔内有无矿石或其它杂物，如有时应清除干净。

（二）破碎机的启动：

1、经检查确认设备传动部分情况正常
