Pebbles have a strong texture and a Mohs hardness of 5-7, belonging to hard rock. Although there are many crushing machinery and equipment on the market now, it is advocated to summarize and consider them to prevent errors in selection due to lack of understanding, which may cause many difficulties in later production. Generally, wear-resistant equipment such as jaw crushers, cone crushers, and impact crushers are used, which are more ideal for processing high hardness materials and also solve the problem of high later costs.
Jaw crusher
Used for first stage and coarse crushing, the principle of kneading and crushing is selected to improve the motion parameters, structural form, and conditioning methods. The deep V-shaped crushing chamber has no dead zone, meeting greater feeding needs and improving efficiency. Wedge blocks are also used to adjust the discharge port for easy adjustment and protection. The crushing ratio is large and the finished product particle size is uniform. In addition, key components such as needle jaw plates and lining plates are made of high manganese steel and high-quality alloy materials, making the whole machine durable.
Cone crusher
Suitable for two-stage and medium fine crushing, the material is kneaded and kneaded by moving from the rolling mill wall to the crushing wall, resulting in a more uniform particle size of the finished product. The structure is simplified and easy to protect and adjust, with low secondary investment costs. The hydraulic motor adjusts the discharge port and is easy to operate. In addition, the crushing wall, rolling mill wall, lining plate and other vulnerable parts are all made of manganese steel, which solves the problem of high operating costs in the later stage and increases the service life.
Impact crusher
Mainly used for fine crushing and sand making, it has a shaping effect. The finished product is relatively fine, mostly polygonal and with good particle size. It is improved through deep cavity impeller planning and crushing chamber collision viewpoint, with increased throughput, central and peripheral feeding, and sensitive adjustment. A combined throwing head is also selected, which only requires replacement of worn parts. The peripheral guard plate can be turned up and down to reduce operating costs. The hydraulic cover opening device is convenient for maintenance and protection.
