High attractive price rock impact crusher made in China

Product Introduction

Hard rock impact crusher has multi-chamber even crushing compared to traditional machines, suitable for crushing hard rocks. The whole plate structure makes particles small and cubic without fissures inside. The low feeding inlet makes it convenient for the production line placement and increases the feeding size. The full-hydraulic device starts up and it's easy for maintenance and renewal of wearing parts. It's mainly applied to secondary crush materials with compressive strength of no more than 320Mpa in the the high grade road, hydropower and construction industries.

Working Principle

It's mainly composed of the base, middle box, back rack, rotor, ratchet flip startup device. Driven by the V-belt, materials are crushed by the hammer on the rotor and are thrown to the toggle plate and then will rebound to the hammer for recrushing. Repeatedly, materials will continuously be crushed to the required sizes. They enter from the first feeding inlet to the first crushing chamber and then to the second crushing chamber. When the size of ores is smaller than the gap between the hammer and the impact plate, materials will be discharged from the lower part of the machine which become finished products.

Performance Characteristics

1. It adopts keyless connection, featured by unique structure, advanced design, reliable performance, stable operation and low energy consumption; the perfect combination of the heavy-duty rotor design, wear-resistant hammer and the crushing chamber design improves the productivity and the quality and reduces the cost and the consumption of abrasive components. Unique hammer fixing device ensures higher reliability of hammer. The impact part is set with spring adjustment structure. When the slag enters into the chamber, it will play the role of tramp iron protection to guarantee the security of equipment.

2. The optimized structure offers bigger chamber and granularity. Meanwhile, the moment of inertia of the rotor is increased to offer higher size reduction ratio and output. The machine is highly-efficient and energy-saving with cubic products.

3. The hammer is fixed on the rotor by a set of wedge with larger torque. More contact between the hammer and the rotor removes the space between them and reduces the probability of the fracture of the hammer. High-quality wear-resistant materials such as high chromium iron are adopted to improve the durability of abrasive parts (such as hammer, impact liner and frame side liner).

Instructions

1. Check whether there is ore bed inside the vortex crushing chamber through the observation door. If there isn't, the materials in the chamber should be no more than 25mm. And the ore bed will be forced until materials can flow automatically.

2. The feeding granularity is strictly in accordance with the specifications. It's not allowed for materials larger than the specified size to enter into the crusher, or it will lead to the imbalance and over-abrasion of the impeller which will further cause the jam of the impeller runner and the center feed pipe. So it must be cleared in time if there are lumpy materials.

3. Looking from the feeding inlet, the rotary direction of the impeller should be anticlockwise or the wiring should be adjusted.

4. Operators cannot stand within the inertia force line when it runs. The installation of switches should be kept away from the position. It's forbidden to check the situation by opening the access door, adjust, clean or maintain the machine in case of danger.

5. There should be no one there in two moving directions of rear box rack when using the hydraulic open-close upper cover system. The block should be placed under the bracket when it starts up and other work can only be underway after reliable and safe operation.

6. It's not allowed to feed indestructible materials in case of damaging the machine. No overload operation is allowed when it runs.

7. The electricity should be firstly cut off when repairing the impact crusher.
