A lot of sand and gravel without processing, is directly used to pave the way, construction and other fields. There are some gravel size is not suitable because of its appearance and the need for further processing can be put into use. These stone processing, need to use special equipment: Gravel
sand making machine. In general, the sand stone is often made of machine-made sand to use. Sand making machine is widely used in gravel mechanism of sand production line. Equipment for sand river gravel general is widely used in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industry and many other departments, various materials with crushing compressive strength less than 320 MPa.
In a sand and gravel mechanism complete production line, not only need to use the sand making machine equipment, also need to use some other auxiliary equipment, such as feeder, single-stage crushing machine, plastic machine, sand washing machine etc.. Customers can according to their actual needs, choose the right equipment. The combination of these devices has great flexibility. Because of a production line cost is very high, for the use of these devices to follow the correct method of operation. At the same time, customers also need to pay attention to maintenance and maintenance problems of these devices, specialized training for nurses the equipment operation. In the maintenance of equipment and maintenance, special attention should be paid to the following problems.
The first is because the sand making machine belongs to the high-speed operation of the equipment in the working process, the staff should pay special attention to safety. The staff should be far away from equipment, if need to tinker's words, must cut off the power before it can carry out the operation. The second is regular downtime open door window observing equipment internal wear, including wear degree circumference guard plate, wear-resistant block, wear should be replaced or repaired, so as not to cause more loss of equipment. It is prohibited to open door window observing work internal equipment crusher work process, so as to avoid the occurrence of safety accidents. Find the impeller body wear, should be promptly replaced. Finally is the sand making machine at work 400 hours should be the addition of appropriate amount of grease; to work 2000 hours to open the spindle assembly bearing cleaning; if the work until 7200 hours later, it must be replaced with new bearings. Bearing is a important part of equipment, state is of crucial importance protect bearings. According to customer requirements of different product sand, sand making machine manufacturers can provide customers more rational design of production line. Customers can also put some of its requirements in the design process.
