Impact crusher main shaft assembly is composed of bearing seat, main shaft, bearings and other components.

Base

Impact crusher eddy current crushing cavity, spindle assembly, electric motor, transmission device are all arranged on the base, a pair of motors are mounted on longitudinal ends, and the base is put on the frame.

Transmission

Impact crusher driving device adopts belt transmission mechanism driven by dual motor, two motors are respectively arranged on both sides of the main shaft assembly, and two motor belts are connected to the spindle belt that balance the force of both sides and avoid additional torque.

Lubrication system

Impact crusher lubricating systems using Mobil vehicle lubricants, super concentrated lubrication or 3# lithium grease, lubricating parts are upper bearing and lower bearing. In order to make lubrication facilitated, we can take it to mechanical lateral by oil tube for oil pump refuel on schedule.

Feed hopper

Impact crusher feeder takes inverted frustum structure; ring wear is arranged on the feed inlet, materials enter the impact crusher through the feeding hopper.

Distributor

Impact crusher distributor is mounted on the upper of the eddy current crushing cavity; the role of distributor is speeding up material until be projected out when they go through the central feeding tube directly into impeller with equal power consumption and reach productivity increasing and efficiency improvement.

Vortex crusher

Impact crusher vortex cavity has a annular space structure which is composed by two segments of cylinder. An impeller rotate with high speed, eddy current crushing cavity can reside material, forming material layer which separate crushing layer and crushing cavity walls so that crushing effect is limited to materials and line themselves. The observation hole sealed shut. Distributor is fixed on the upper cylindrical section of eddy current crushing cavity; High-speed rotating impeller products angry flow, they flow though distributor and impeller, forming self circulation system.

Impeller

Impact crusher impeller is a hollow cylinder made of special material, it is mounted on a spindle assembly end head, cone sleeve and binding transfer torque, high rotating speed impact crusher impeller is the key components, the material enter into the impeller from the upper wheel feeder central feeding tube, central cloth cone allocate to the each emission stream crossing on average, Head cast material is equipped with special material and can be replaced. 

Impeller material will be projected out when it is accelerated to 6075 M / s, it first form an impact with waterfall materials, and then hit the eddy lining and lining again. A channel plate is provided between the conical cap and polishing material, protecting impeller from wearing.

In general, there are three main formation types of weathering sand ,as follows:

First, mechanical weathering sand. It is due to changes in temperature and water and salt state changes in rock gap.

Second, chemical weathering sand. Oxygen and water solution not only makes the surface near the rock breaking, and makes their chemical composition change, this is the chemical weathering. Through chemical reaction make those unstable minerals in the surface conditions to be another new mineral (to adapt to the surface environment).

Third, biological weathering sand. As the creature have physical and chemical properties, so biological weathering sand is the merging of above two. And it often comprehensive effect appear. The existing stone mill is insufficient in the processing of weathered sand capacity. Because they more use the mixing of crushing and conveying equipment, if weathering effect is obvious, they directly fine tailings after intermediate crushing. While the match has high requirement on accuracy and waste time, efficiency is also comparatively low. Traditional crushing theory have lower control on the particle size so the capacity and power consumption did not reach the high optimization and still need to be improved.

As a leader in sand maker industry, according to the research of weathered sand, standard sand and building sand, Henan Hongxing Machinery Limited company accumulates years of impact crusher's development experience, create professional 5X series high efficient impact crusher, which introduce Germany advanced mining machinery engineering technology reach crushing, washing and grading simultaneously, product qualified gravel aggregate products one-time and be focused in market by its high utilization rate.
