Our sand production line mainly consists of vibrating feeder, jaw crusher, sand making machine, vibrating screen, sand washing machine, belt conveyor, electric control panel, etc, and capacity is 50-500T/H. Our sand production line is taking the leading role in the sand making industry. Sand production line can crush hard limestone, granite, basalt, river stone, etc, and widely used in hydropower, building material, highway, city construction, etc.
Usually, the material stacking height in the crushing cavity should not more than the 2 / 3 of crushing chamber, and the diameter of the materials should not be more than the 50%-60% of the inlet width, the jaw crusher has a highest production capacity at this condition. When the materials with larger piece, it will cause blockage affecting the normal production. To prevent metal ( such as the spade teeth, crawler plate, bits ) from entering the jaw crusher and avoid damaging the machine, it should be brought out when they pass through the jaw crusher to prevent causing accident; when the electrical equipment automatic trip, if the cause is unknown, forbid forced continuous starting.
Process of Sand Production Line:
The raw material is transferred to jaw crusher for primary crushing by vibrating feeder, then the crushed materials are transferred to sand-making machine through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen. The materials with suitable size will be transferred to sand washing machine, after being washed, then clean final products will be discharged. The others with unsuitable size will be screened from vibrating screen, then will be transferred to the sand-making machine, this forms a closed circuit manifold cycles.
Because it is a series of equipments instead of one sand making machine from starting the sand production line to its normal operation, the operation is a very rigorous work, so there must be a professional personnel to start it. Owning to the multi-equipment, hard work, high degree of difficulty, which requires the staff very well master the run and operation steps. We will introduce few operation specification and matters need attention in the operation, and the details are as follows:
Matters need attention when starting a sand making production line : after preparation, according to the provisions of the driving sequence operation to start the main motor, when starting the motor we shoul pay attention to the current meter of the control cabinet, after starting the peak current for 30-40s, the current will reduce to a normal operating current value. In the normal operation, we also should pay attention to current which should not be more than the specified value. After the normal operation of the jaw crusher, it can actuate the feeding machine, and according to the block size and the operating condition of the jaw crusher adjust the feeding machine belt and change the feed quantity. Clearing the operation specification of various equipments in sand making production line is very necessary for the safe to human body and equipment application.
