In the machine-made sand processing production line, because the inlet of the sand making machine is relatively small, generally less than 5 cm, the configuration of the previous crushing equipment is often indispensable. Jaw breaking and hammer breaking are frequently used equipment in sand making production lines. When should we use jaw breaking? When should I use a hammer to break? How should I choose?
We mainly discuss from the following three aspects:
一. Broken materials
1. Jaw crushing can crush all kinds of soft and hard materials, the compressive strength is between 300-500Mpa, such as common granite, quartz stone, diabase, river pebble, iron ore, etc.
2. Hammer crusher is mainly used to crush materials with low hardness and relatively soft. The compressive strength is generally lower than 200Mpa, such as limestone, bluestone, coal gangue, etc.
二. Production line scale
1. The content of needle pieces in the jaw crusher is relatively high. Generally speaking, it is necessary to cooperate with the counterattack for shaping. Therefore, in the machine-made sand processing production line, we often see the configuration of jaw breaker + counterattack breaker.
2. Hammer crusher is mainly used for industrial secondary crusher, forming once, without the need of secondary crushing and shaping process. Therefore, a single hammer breaker is a commonly used equipment in small and medium-sized production lines.
三. application method
1. Jaw crusher is often used as the coarse crushing equipment in the sand production line, followed by impact crushing or cone crushing, etc., followed by sand making machine for shaping.
2. Although the process of hammer crusher is simple, the yield rate is relatively low, it is easy to be crushed, and there are many powdery materials. In addition, micro-cracks may occur in the finished sand and gravel aggregate, and the compressive strength is relatively low, which affects the quality of the aggregate. , It also affects sales and prices, so hammer crushing is used as an auxiliary sand making equipment.
The above is the experience shared with you today on how to choose hammer breaking and jaw breaking. We must be clear about our needs when choosing equipment, so that we can build a sand making production line that suits us, save investment, and optimize configuration. If you have any questions about the configuration of the production line, you can consult in detail.
