青石是各种石材中环保的石材，因取材方便，具有耐磨、耐风化、无辐射等特点，破碎后广泛用于建筑行业中。青石破碎生产线每小时可生产30-3000吨物料。青石破碎生产线设备有：给料设备、破碎设备、筛分设备、输送设备、制砂设备、洗砂设备、除尘设备组成。
青石破碎机是青石破碎生产线的设备之一。主要作用是：将从山上开采的大块青石料进行破碎，破碎至25-20mm以下成品料，破碎+整形，二合一设备。
青石破碎机工作原理：电动机经三角带、大带轮带动转子高速旋转；待破碎物料由喂料设备经入料口送入破碎腔、高速旋转的转子带动锤头对物料进行次打击；获得动能后的物料高速撞向反击板得到二次破碎；碰撞反弹后或遭锤头再次打击或与其它物料相互碰撞。物料在碰撞的过程中逐渐向破碎腔下部的活动反击板移动，当物料粒度小于锤头与活动反击板之间的间隙时，在自重和其它物料的压挤下脱离破碎腔,从而结束一个完整的破碎过程。排出后的物料由筛选设备筛选后,部分大于选用标准的物料,需运送破碎机进行二次破碎。
青石碎石机是青石制砂生产线中的设备。主要用于：将破碎设备处理后的半成品料进行加工处理，获得用于盖房的大沙。
青石碎石机工作原理：青石碎石机主要由机体、破碎板、上转子、下转子、摆锤、旋转驱动装置、筛板等组成，该机在工作过程中两个转子相对运转，进入破碎腔的物料由个转子上的锤头进行打击破碎并获得的动能后撞向第二个转子，由于第二个转子与物料飞来的方向相反，此时第二个转子对物料的打击速度等于两个速度的叠加，物料经如此多次的循环打击而破碎后经篦条的缝隙排出。破碎原料(石灰岩、青石、砾石、煤矸石、煤、片麻岩等)通过ZG振动给料机均匀地喂入PCZ重型锤式破碎机初步破碎，经粗碎后的成品通过皮带输送机输送至PC锤式破碎机破进一步破碎，二次破碎后的石料通过皮带输送机输送至青石破碎机再次破碎，再次破碎整形处理的石料通过皮带输送机输送至YK振动筛筛分出不同规格的石子，满足客户粒度要求的石子通过皮带输送机输送至成品料堆，不合格的石子通过皮带输送机重新返回至青石破碎机再次破碎，形成闭路多次循环完成。
Qingshi is an environmentally friendly stone among various types of stones. Due to its convenient material selection, it has the characteristics of wear resistance, weathering resistance, and non radiation. After crushing, it is widely used in the construction industry. The bluestone crushing production line can produce 30-3000 tons of materials per hour. The equipment for the bluestone crushing production line consists of feeding equipment, crushing equipment, screening equipment, conveying equipment, sand making equipment, sand washing equipment, and dust removal equipment.
The bluestone crusher is one of the equipment in the bluestone crushing production line. The main function is to crush large pieces of green stone extracted from the mountain, crushing them to finished materials below 25-20mm, and using a two in one equipment for crushing and shaping.
Working principle of bluestone crusher: The motor drives the rotor to rotate at high speed through a V-belt and a large pulley; The material to be crushed is fed into the crushing chamber through the feeding port by the feeding equipment, and the high-speed rotating rotor drives the hammer to strike the material; After obtaining kinetic energy, the material collides with the counterattack plate at high speed and undergoes secondary crushing; After collision and rebound, or being hit again by a hammer or colliding with other materials. During the collision process, the material gradually moves towards the movable impact plate at the bottom of the crushing chamber. When the particle size of the material is smaller than the gap between the hammer head and the movable impact plate, it separates from the crushing chamber under its own weight and the pressure of other materials, thus ending a complete crushing process. After the discharged materials are screened by the screening equipment, some of the materials that are larger than the selected standards need to be transported to the crusher for secondary crushing.
The bluestone crusher is an equipment in the bluestone sand production line. Mainly used for processing semi-finished materials processed by crushing equipment to obtain large sand for building.
Working principle of bluestone crusher: The bluestone crusher is mainly composed of a body, a crushing plate, an upper rotor, a lower rotor, a pendulum, a rotary drive device, a sieve plate, etc. During the operation of the machine, the two rotors rotate relative to each other. The material entering the crushing chamber is crushed by the hammer head on each rotor and the kinetic energy obtained is then collided with the second rotor. Since the direction of the second rotor is opposite to the direction of the material flying, the impact speed of the second rotor on the material is equal to the superposition of the two speeds. After so many cycles of impact, the material is crushed and discharged through the gap of the grate. Crushed raw materials (limestone, bluestone, gravel, coal gangue, coal, gneiss, etc.) are uniformly fed into the PCZ heavy-duty hammer crusher through a ZG vibrating feeder for initial crushing. The roughly crushed finished product is transported to the PC hammer crusher for further crushing through a belt conveyor. The stone material after secondary crushing is transported to the bluestone crusher for further crushing through a belt conveyor. The stone material after further crushing and shaping is transported to the YK vibrating screen for screening different specifications of stones through a belt conveyor. The stones that meet the customer's particle size requirements are transported to the finished material pile through a belt conveyor, and the unqualified stones are returned to the bluestone crusher for further crushing through a belt conveyor, forming a closed circuit for multiple cycles to complete.
