Stone production line is also known as sand making production line. It is the special production line for making sand and stone used in construction, road, and railway industries. the stone crushing equipments consist of jaw crusher, stone crusher, impact crusher, vibrating feeder, vibrating screen, sand washer, and belt conveyor etc. the equipments manufactured by our company have the advantages of reliable performance, reasonable design, easy operation, and high efficiency.

Consist of sand production line: mainly consist of vibrating feeder, jaw crusher, impact crusher, circular vibrating screen, belt conveyor. The capacity mainly vary between 50-500thp. And in order to meet the different demands of customers, the production line can equip with cone crusher, dust removal equipment and other equipment. It is suitable for the materials like hard limestone, granite, basalt, pebble, metallurgy slag and artificial sand making work. It is widely used in the industries of hydroelectric, building materials, highway, and urban construction. And according to different technological requirement, various types of equipment can be combined to meet the demands of different customers.
After we have known the working mechanism of the sand making machine, we can focus on the optimization of the workflow. The engineers of Henan Hongxing Mining Machinery believe that the following five aspects should be noted.
First, check if the observation door of the eddy chamber is closed to prevent the material from bursting out of the eddy chamber. Second, check the rotating direction of the impeller from the direction of the feed inlet. The impeller should rotate counterclockwise; otherwise you should adjust the wiring of the motor. Third, the startup sequence of the sand making machine and conveying equipment should be as followings: discharging → sand making machine → feeding. The crusher must be started without load. Feed after the crusher is in normal operation. Forth, the feed particles strictly follow the regulations. The materials which are greater than the specification should be forbidden into the crusher; otherwise, it would cause imbalance of the impeller or too much wear and tear of the impeller. Fifth, if the discharge device stops moving, it is timely to stop feeding. Otherwise, the impeller will be crushed and the motor will be burned up. In order to ensure the normal operation of the sand maker and give full play to the capacity of the equipment, the majority of sand making machine users should ideologically emphasis on the correct operation of the sand making machine with regular maintenance and periodic maintenance.
Characteristics
1.Stone crushing production line carries the following characteristics: highly automatic, high compression ratio, high efficiency, large processing quantity, cubic shape of finished product with minimum needle and slice shaped product, high compression strength without inner crack.
2. Easy to maintain and repair; wearing parts are made from abrasion resistance material with domestic advanced high level with low in abrasion and long in using life. Considerable economic profile can be brought by doing this.
3. Stone crushing production lines designed by our company are successfully applied in limestone, basalt, granite and pebble; the finished product reaches the standard of GB14685-2001, which is the best aggregate for highway, railway, water conservancy and concrete mixing station.
Properly using the sand maker is an important factor to ensure the continuous normal work of the sand making equipment. Improper operation or negligence in the operation will often cause the accident of the equipment and personal accident. Therefore, correct operation should be strictly in accordance with the provisions of the operating procedure
