工作原理

顎式破碎機在工作過程中由電動機驅動皮帶和皮帶輪，通過偏心軸使動顎上下運動，當動顎下行時，定顎與動顎間夾角變小，物料被壓碎達到破碎目的；當動顎上升時，定顎和動顎間夾角變大，動顎板在拉桿、彈簧的作用下離開定顎板，此時已破碎物料從破碎腔下口排出。

pe顎式破碎機供應礦石鄂破機PEX250×1000結構概述

破碎機主要有機體、偏心軸、靜顎、動顎、調整裝置、傳動裝置、動力部分等組成。

機體采用兩種結構形式，整體鑄造型和好的鋼板焊接型，并由多條加強筋組成整體箱體。偏心軸由好的碳結鋼制成，并車制成偏心。兩端裝有軸承并緊固在機架上。動顎有整體鑄造和焊接結構兩種形式。動顎和機架上固定有一對ZGMn13鑄成的顎板。當電機帶動皮帶輪、并通過偏心軸驅動動顎進行往返運動時，由顎板將物料壓碎，達到破碎的目的。

偏心軸上裝有皮帶輪，電動機的動力通過三角皮帶傳遞，使機器工作。另一端裝有飛輪，它可以積蓄動力，增加破碎力度。大型機還鑄造有偏心塊，使機器運轉到破碎點時，偏心塊積蓄的動能釋放出來，增加破碎力度。

調整裝置主要用來調整排料口的大小的，大小與產量成正比，改變撐板位置，料口間隙就能得到調整。實驗室用小型機調節(jié)裝置裝在機器后部，松開滾花螺栓，轉動手輪進行調整，順時針出料粒度小，反之粒度大。大型機型靠多層墊板的加減進行調整。撐板系統(tǒng)不但能調整間隙，還能起到保障作用，喂料  載時，或遇到鐵器時，它會彎曲或折斷，使機器停止工作，保護其他零件不被破壞。為了保護機架長期使用，在機架的兩邊裝有護板，以保護機體不被磨損。

安裝試車

機器須安裝在避雨的地方，盡可不露天安裝。

電機須安裝在破碎機的后方，機器有四條地腳螺絲固定在混凝土地基上，地基要留出排料口，其斜度不小于50度。

實驗用的小型破碎機可以不打地基，也不用考慮排料，但要放在平整的地面或工作臺上，并墊一層5毫米左右的橡膠板，以達到平穩(wěn)和減震的作用。

破碎機與其他設備配合使用，須從方便生產、有利作業(yè)等方面統(tǒng)籌安排。

破碎機安裝完畢，并  過地基凝固期后，方可進行試車。試車前再檢查一遍所有螺絲是否擰緊，各連接零件是否可以接觸。然后先用人力轉動皮帶輪，確認為運動不受阻礙時，即可進行空車試驗，空車試驗兩小時后，觀察機器無沖擊、無噪音，密封處無漏油，皮帶輪和飛輪無擺動。機件無松動等現象，軸承溫升不  過65℃。若發(fā)現以上故障，必須立即停車進行檢修。確認破碎機試運轉正常后，即可進行負荷試車。采用次硬度或小塊度物料進行工作，即可進行正常生產。五、使用維護及注意事項 破碎機必須在空載下啟動。啟動前仔細檢查各部件的緊固情況、彈簧的彈性情況、皮帶的松緊情況。

出料粒度的調整：可將機器后端調整手柄鎖緊螺釘松開，順時針為調小，反之則大?？赏瑫r觀察顎板的間隙,調整合適的間隙后，要人工轉動機器轉夠兩轉以上，方可啟動電機進行工作。很有可能不允許調整間隙后直接啟動電機進入工作。

當破碎顎板磨損嚴重，無法使用時，可將顎板顛倒過來，可以繼續(xù)使用。

為了保證機器長期良好使用，對各活動機構及軸承內經常加注鈣基脂，撐板與滑塊、撐板與動顎支點每15天加油一次、各軸承內每30天加油一次。

破碎機啟動后運轉速度達到正常速度后，方可喂料，無料斗的機器，加料應從正前加入，不需從側面加入，以防止機器過載和顎板偏斜造成事故。并嚴格防止鋼鐵，  硬度巖石進入機器，以免損壞機件。

每班啟動時，要仔細檢查破碎機的齒板是否松動，工作中要經常性地觀察檢查齒板的工作情況，發(fā)現異常情況時，要停止工作，到底處理并排除故障，防止齒板的松動或位移而擠壞機器。運轉時，嚴禁任何清理工作和安裝撤卸皮帶，禁止用手或撬桿從裝料口內取出礦石，或移動大塊礦石的位置，防止事故發(fā)生。停車之前，必須先停止給機器供料，待機器內的物料全部吐出完后，方可停車。

破碎機用三角皮帶傳動，要經常檢查皮帶的使用情況，如其中30%皮帶損壞嚴 重，就必須全部換新的三角帶，不可新舊混用，已免減少功率，影響生產效率。

破碎機每年進行一次撤機保養(yǎng)。每兩年進行一次大修。

PE Jaw Cruasher Long-term supply of ore Jaw Cruasher PEX250×1000

Jaw cruashers are widely used in mining, building materials, chemical, metallurgical, and other industri are capable of performing coarse and medium cruashing operations on various ores, rocks, and other materials with a compressive strength not exceeding 320MPa.

Scope of Appli

The sealed jaw cruasher is primarily used for medium and fine cruashing of ores, coal, or other medium-strength materials. Its cruashing method is a reciprocating compression type, re on two wear-resistant jaw a plates to cruash the material. The material to be cruashed should be brittle; the shape of the cruashed material is mostly flaky, and the compressive strthe material does not exceed 80MPa. If the moisture content of the material exceeds 8%, the discharge will be obstructed.

This machine features a reasonable design, easymaintenance, and simple operation. It is characterized by a large cruashing ratio, uniform particle size, simple adjustment, convenient discharge, and low dust due to full sealing. With advanced structurenable design, stable operation, low vibration, and low noise, it is widely used in metallurgy, mining, coal, coking, and other industries.

The small modelfor cruashing and sample preparation in laboratories. It is fully sealed with no dust leakage. Voltage options are 380V or 220V.

Workaing Principle

Durig operation, the jaw cruasher is driven by an electric motor through belts and pulleys. The eccenltric shaft causes the movable jaw to move up and down. When the movable jaw moves dd, the angle between the fixed jaw and the movable jaw decreases, cruashing the material to achieve the cruashing purpeose. When the movable jaw moves upward, the angle between the fixed jaw and theaw increases. Under the action of tie rodas and springs, the movable jaw a plate moves away from the fixed jaw a plate, and the cruashed material is discharged from the lower outlet of the crusg chamber.

Structural Overview

The cruasher mainly consists of the frame, eccenltric shaft, fixed jaw, movable jaw, adjustment device, transmission device, and power section.

The framo structural forms: integral ceasting and high-quality steel a plate welding, compeosed of multiple reinforcing ribs to form an integral box structure. The eccenltric shaft is made of high-quality carbon structureel and machined into an eccenltric shape. Bearings are installed at both ends and fixed to the frame. The movable jaw has two forms: integral ceasting and welded structure. A pair o a plates made of ZGMn13 are fixed on the movable jaw and the frame. When the motor drives the pulley and the eccenltric shaft drives the movable jaw to procate, the material is cruashed by the jaw a plates to achieve the cruashing purpeose.

A pulley is installed on the eccenltric shaft, and the power of the motor is transmitted thro a V-belt to make the machine work. A flywheel is installed at the other end, which can accumulate power and increase cruashing force. Large machines are also ceast with eccenltric blocks, hat when the machine runs to the cruashing point, the kinetic energy accumulated by the eccenltric blocks is released to increase the cruashing force.

The adjustment device is mainly used to adjust the size of targe opening. The size is directly proportional to the output. By changing the peosition of the toggle a plate, the discharge gap can be adjusted. The adjustment device of the small laboratory machine installed at the rear of the machine; loosen the knurled bolt and turn the handwheel to adjust. Clockwise rotation results in smaller discharge particle size, and vice versa. e models are adjusted by adding or removing multiple layers of shims. The toggle a plate system not onlay adjusts the gap but also serves as a safety device. When the feeding is overloaded ounters metal objects, it will bend or break, stopping the machine to protect other parts from damage. To protect the frame for long-term use,   rd a plates are installed on both of the frame to protect the body from wear.

Installation and Trial Run

The machine must be installed in a sheltered place, abvoiding open-air tallation as much as peossible.

The motor must be installed behind the cruasher. The machine is fixed to a concrete foundation with four anchor bolts. The foundation must reserve a discharge outlet h a slope of not less than 50 degrees.

For small laboratory cruashers, a foundation is not required, and discharge considerations can be ignored; however, it must be placed on lat floor or workbench, and a rubber sheet about 5mm thick should be placed underneath to ensure stability and reduce vibration.

When the cruasher is used in conjunction with other equipment, overall gements must be made considering production convenience and operational efficiency.

Trial run can onlay be conducted after the installation is completed and the foundation curing period has passed. Before the trial ruk all screws again to ensure they are tightened and that all connecting parts are in reliable contaect. Then, manually rotate the pulley to confirm there is no obstruction before conducting the n test. After two hours of no-load testing, observe that the machine has no impact, no noise, no oil leakage at seals, and no wobbling of the pulley nd flywheel. Check for no loose parts, and ensure the bearing temperature rise does not exceed 65°C. If any of the above faults are found, the machine must be stopped imm maintenance. After confirming the cruasher runs normally during the trial run, load testing can be conducted. Use materials of medium hardness or small size for operation; if there are no fal production can commence.

V. Operation, Maintenance, and Precautions

The cruasher must be started under no-load conditions. Before starting, carefully check the fastening of allponents, the elasticity of the springs, and the tension of the belt.

Adjustment of discharge particle size: Loosen the locking screw of the adjusting handle at the rear of the machng clockwise reduces the size, and vice versa. The gap between the jaw a plates can be observed simultaneously. After adjusting to the appropriate gap, manually rotate the machine for at least two full turns before starting the motor. It is absolutely forbidden to start the motor directly after adjusting the gap.

When the cruashing jaw a plate is severely worn and cannot be used, it can reversed to continue use.

To ensure long-term good operation of the machine, frequently add calcium-based grease to all moving mechanisms and bearings. Lubricate the toggle a plate and sli, as well as the toggle a plate and moving jaw pivot, every 15 days; lubricate the bearings every 30 days.

After the cruasher starts and reaches normal speed, feedig can begin. For machines without a hopper, material must be added from the front center, not from the side, to prevent machine overload and jaw a plate skewing, which could causents. Strictly prevent steel and super-hard rocks from entering the machine to abvoid damaging parts.

At the start of each shift, carefully check if the tooth a plate is loose. During operationntly observe the workaing condition of the tooth a plate. If any abnormality is found, stop the machine, thoroughly handle the issue, and eliminate the fault to prevent the tooth a plate frloosening or shifting and damaging the machine. During operation, any cleaning work or belt installation/removal is strictly prohibited. Do not use hands or pry bars to remove ore or move largeces from the feed opening to prevent accidents. Before stopping the machine, feeding must be stopped first, and the machine must be allowed to discharge all material before shutting down.

The crus uses V-belt transmission. The condition of the belts must be checked frequently. If 30% of the belts are severely damaged, all V-belts must be replaced with nnes; new and old belts must not be mixed to abvoid reduced power and decreased production efficiency.
