Fourth, the general rotating machine empty load running time of 4 hours, feed size load test run in strict accordance with the specifications of various models, greater than the specified prohibited materials into; uniform continuous feed, water content of not less than 10-15% (available Depending on the material) Sand manufacturers, feed-through impact crusher PCL reach full capacity until; 8-24 hours load test run five times, check before starting Sand observe vortex chamber door is closed, to prevent the material from Observation of vortex chamber door out of the sand making plant, dangerous. Check the boot order of the impeller and transportation equipment: 1, nesting - → Sand - → feed 2, Sand must load start until after the crusher is operating normally before feeding. 3, stop and turn the opposite order. Six, Sand feed size in strict accordance with the requirements, greater than the specified prohibited materials into the crusher, otherwise, it will cause an imbalance of the impeller and impeller Sand excessive wear, or even clog impeller channel and center into the feed tube, so Sand does not work, find great material should be immediately removed. Seven former host Sand stopped working, stop feeding, otherwise it will cause impeller crushed, burned the motor. Feeding should be uniform. Sand during operation, without severe vibration and abnormal noise, otherwise, you should stop to check. Dry lubrication oil lubrication, using car grease or 3 # lithium grease. Sand after every 100 hours add the right amount of grease. Under normal circumstances, the use of sand making note of these points can also be followed in the case of artificial sand making use of the rules work to ensure that Sand's life, as well as product quality, economic and even personal safety loss. Impact crusher (sand machine) features: 1. Structure simple and reasonable, since the strike-breakers, the use of ultra-low-cost; 2. Unique spindle bearing installation and advanced design, so that the machine has a heavy load and high speed rotation features. 3. With crushing, coarse grinding function; 4. High reliability, tight security devices to ensure equipment and personal safety; 5. smooth operation, working noise, energy efficient, high crushing efficiency; 6. subject material moisture content little impact, moisture content up to about 8%; 7. wearing parts, low loss, all wearing parts are made of high quality wear-resistant materials at home and abroad, long service life. A small amount of wear parts made of special hard wear-resistant material, small size, light weight, ease of replacement parts. 8. Since the internal vortex chamber airflow circulation Sand, small dust pollution. 9. impeller and whirl crushing cavity lining material from the substantial reduction in the cost of wear parts and maintenance workload. Production process, can form a protective layer of stone, sand making body no mechanical wear and durability. 10. Install and diverse, mobile installation. 11. The product was a cube, bulk density, small iron contamination. Cobblestone Sand | Sand camphor | Yuxin Senda provided by Henan new Senda Heavy Machinery Co., Ltd..
