What crusher and sand making machine are used to make pebbles into sand?
Crushing, sand making, screening and other technological processes are generally required to break the pebbles in the river into sand. If higher quality and high purity sand products are required, a sand washing machine is also required for cleaning; then, for the hardness of the pebbles The larger the problem of strong wear and tear on the equipment, how should we choose the crusher and sand making machine with wear resistance and long service life?
The first thing we need to understand is that if the shape of the stone is large, it needs to be crushed by a primary crusher first. The commonly used primary crusher is the jaw crusher. The jaw crusher has a large feeding port and can process large stones , and the crushing ratio is large, it is easy and reliable to crush large stones to below medium particle size at one time. If you want to complete one-time forming, you can equip with a cone crusher. The cone crusher may choose the VU sand and gravel aggregate system, which has both crushing and shaping effects, which saves time and effort, saves technology, and is convenient and reliable.
After rough crushing, fine crushing is required. Generally, cone crusher, impact crusher or fine crusher are selected as fine crushing equipment. Cone crusher mainly uses bending extrusion method to crush stones, which is suitable for processing high hardness ores. Impact crusher mainly uses impact method to crush stones, which is suitable for processing medium hardness ores. Fine crusher uses high-speed impact effect of rotor to crush stones, The fine particle size can be less than 10mm.
The finely crushed sand cannot be used directly, and a sand making machine is required for sand making. At present, the more environmentally friendly and intelligent sand making machines are the VU sand and gravel optimization system and the new VSI sand making machine. Among them, the VSI6X sand making machine uses a deep cavity. The impeller can increase the throughput by 30%. Equipped with a combined material throwing head, only the worn part needs to be replaced, which can greatly reduce the operating cost. The whole machine adopts the modular design of the bearing chamber, the western oil type and the grease type, which can complete the whole exchange and is convenient reliable.
VSI sand making machine can process a variety of standard products, such as 0-2mm, 2-5mm, 5-10mm, etc., with uniform particle size, reasonable gradation, high hardness and no cracks, which meets the high standard material requirements in the construction field. The sand washing machine needs to be used for cleaning sand products. The specific stage to use the sand washing machine depends on the characteristics of the material. The sand washing machine continuously turns over the impeller to clean out the mud, mud, stone powder and rot in the sand. The structure is simple, durable, and the processing capacity is large at one time, because the water, sand and the transmission device are isolated, so the overall failure rate is greatly reduced.
