Jaw crushers are generally installed on the foundation of concrete. In view of the heavy weight of the crusher, the working conditions are bad, and the machine generates a large inertia force during operation, which causes the basic and machine systems to vibrate. The vibration of the foundation directly causes vibrations of other machine equipment and building structures. Therefore, the foundation of the crusher must be separated from the foundation of the plant. At the same time, in order to reduce vibration, an rubber or wood liner is placed between the crusher base and the frame. In order to ensure the continuous production of the crusher, and to fully utilize the production capacity of the equipment, it is necessary to pay attention to the correct operation, frequent maintenance and regular maintenance of the crusher. One of the important factors that ensure the continuous operation of the crusher in the correct operating room. Improper operation or negligence during operation is often an important cause of equipment and personal accidents. The correct operation is carried out in strict accordance with the provisions of the operating procedures. Preparation before start-up: Before the jaw crusher is started, the equipment must be thoroughly inspected: check the wear of the broken tooth plate, adjust the size of the discharge port; check the ore in the crushing chamber, if there is a large block The ore must be taken out; the coupling bolt is loose; the protective cover of the pulley and the flywheel is intact; the tightness of the V-belt and the tie-bar spring is appropriate; whether the electrical equipment and signal system are in production or not. Before starting the crusher, the oil pump motor and cooling system should be started first. After 3-4 minutes, when the oil pressure and oil flow indicator are normal, the motor of the crusher is started. After starting, if the crusher makes an abnormal knocking sound, it should stop running, find out and eliminate the ills, and restart the machine. The jaw crusher must be started at no load. After the start, after a period of operation, the normal operation can start the feeding equipment . The ore fed to the crusher should be gradually increased, knowing that it is fully loaded. In operation, attention must be paid to uniform ore, and the ore is not allowed to be filled with crushing chambers; and the maximum size of the ore should not be greater than 0.85 times the width of the ore. At the same time, the non-crushing objects such as the shovel-toothed drill bit of the electric shovel are strictly prevented from entering the crusher. Once these non-broken objects are found into the crushing chamber and pass through the discharge port of the machine, the belt transport post should be immediately promptly taken out to avoid entering the next section of the crusher, causing serious equipment accidents. (two) the use of roller crusher skills The roller crusher is the wisdom of our company's many years of mining machinery and equipment manufacturing and correct decision-making. Is an advanced level of high energy with low consumption device, it plays an irreplaceable role in a variety of ore crushing plant, the product widely used in cement, refractories, aluminum, bauxite, stone, glass raw material gold emery , construction sand goose sand and various metallurgical mining and other industries. 1. It is necessary to strengthen the iron removal work for the mine. If the non-crushed material (such as a bit) falls into the pair of rollers, the crusher will be damaged, resulting in a parking accident. Therefore, a de-ironing device should be installed in front of the crusher. 2. The viscous material is easy to block the crushing space. It should be stopped when handling the blockage failure, and the antimony ore should not be carried out during operation. 3. When the material to be processed contains more large pieces, it should be noted that large ores are easily squeezed out from the crushing space to prevent injury or damage to the equipment. 4. After the roller crusher is operated for a long time, due to the large wear of the roller surface, the product size will be too fine. At this time, it is necessary to pay attention to adjusting the discharge port or repairing the equipment. 5. Strengthen the inspection of the equipment, and refuel the equipment on the lubrication parts to keep the equipment in good lubrication.
Hdpe rod and sheet is a high crystallinity and non-polarity thermoplastic resin,HDPE Rod and sheet has good chemical stability, which can resist corrosion of most acid,alkali,organic solution and hot water; good electric insulation property and is easy to weld.
AHD is the first to produce ultra-thick PE plate (with a thickness up to 200 mm) in China,whom started to research,develop and produce HDPE rod and sheet in 2002.
HDPE rod and sheet are widely applied to drinking water/sewerage pipe,hot water pipe,conveying container,pump and valve part, medical appliance,seal part,cutting plate and sliding material in chemical industry,machinery,power plant,garment,packaging and food industries.
