Description

Circular Vibrating Screen Installation


Before installing the machine , first check the packing list and damaged parts are complete , which date from the factory vibrator , if more than six months , must be washable and re- assembled and put on clean oil . Follow the installation diagram for equipment installation , including supporting chassis must be mounted horizontally on the foundation , the foundation should have sufficient stiffness and strength , all the dynamic load and static load to support the shaker . There are corners of the screen box lug , bearing chassis four corners lifting holes , according to plans require lifting, can not be directly linked to the lifting of the entire sieve shaker . Should be maintained to ensure a minimum 75mm gap between the screen box and hopper , chute ( chute ) , and other similar non- moving parts . Press freedom damping spring height matching, respectively, the left and right sides of the front-end or back-end of the spring free height equal as possible , the error does not exceed 5mm. After installing the screen box , the screen surface remain around the level Otherwise, a thin iron sheet pad between the spring seat and the support member .pebbles sand production line configuration


Adjustment and commissioning


Spring must be in a vertical position , the spring and the spring bearing contact surfaces must be horizontal state , the carriage bolt fixed on the screen box spring trunnion adjustment is completed, then spot welded into one. Circular orientation shaker drive , the feed end of the standing face of the motor viewed in the direction of material flow position to the left or right to get the driver . Ensure that the V-belt tension adjustment amount sufficient to ensure that the two tape wheels corresponding grooves within their plane correspondence. After the installation and adjustment should be carried out not less than 2h -load test run , for a smooth operation , no abnormal noise , amplitude and trajectory to meet the requirements , bearing the maximum temperature does not exceed 75 ℃. No-load test run after passing the load can be put into trial operation , the load test time can process test requirements . Must hand ( or other methods ) before turning the shaker test . Rotation should be flexible , when there is no jamming phenomenon , before the official start the machine .manufactured sand production line


Crushing machinery circumstances force


Any kind of offal machine and grinding machine is not only one force crushed stone , usually some kind of force -based, with the other types of action , therefore , ore crusher quit giving force is complex. For ease of analysis and research , generally considered the main focus on the force of the impact force to the other species examined only as incidental . Commandment of force situation crusher can be divided into crushed, split, broken, grinding stripping and shock . Mechanical force is different, the intensity should be considered ore types are different. For the crushed ore compressive strength should be considered : For split , pay attention to its compressive strength ; to break , to note that the flexural strength of the ore ; while grinding stripping ore , it should consider its shear strength . Crushing machinery is working with its members to act on repeated dynamic loading of ore , which has a certain impact. When the impact of other ores , it should consider the impact strength . After studying at the various crusher works, the force of their case, it should distinguish , for example, when the ore is crushed between the jaw crusher tooth plate by a split effect, anti- split strength of about ore 1.2 times the tensile strength .pebbles sand production line configuration
