The board hammer sand making machine is suitable for making sand from various hard stone materials
Plate hammer sand making machine
1、 Application scope: The composite crusher is a sieve free and adjustable fine crushing equipment optimized and designed based on advanced fine crushing equipment at home and abroad. It can be widely used for fine crushing of raw materials and clinker in cement plants, as well as for fine crushing of medium hardness materials such as dolomite, pyroxene, lead-zinc ore, serpentine, blast furnace slag, coal gangue, phosphate rock, etc. It is particularly suitable for the processing and crushing of artificial sand or highway pavement materials such as hard limestone, dolomite, granite, basalt, etc. The composite crusher has a large crushing ratio and the discharge particle size can be adjusted arbitrarily, without being affected by the wear of the plate hammer and lining plate; No screening strip setting, it is not easy to block when crushing materials with high moisture content and high mud content; Adopting an elastic adjustment mechanism, the unbreakable material can be automatically discharged without causing equipment damage; Horizontal arrangement of bearings, long service life, capable of crushing high-temperature materials (such as cement clinker); The rotor structure of this machine is unique, and it hardly wears out when crushing materials; The rear chamber is equipped with a screw or hydraulic opening mechanism, making it easy to replace vulnerable parts without starting the main equipment.
2、 Working principle of composite crusher: The material vertically falls into the high-speed rotating impeller from the upper part of the machine, and under the action of high-speed centrifugal force, it collides and crushes at high speed with another part of the material that is divided in an umbrella shape around the impeller. After colliding with each other, the material will form vortices between the impeller and the casing, and collide and rub against each other multiple times to crush it. It is discharged directly from the lower part, forming a closed loop for multiple cycles, and controlled by the screening equipment to achieve the required particle size of the finished product.
3、 The working characteristics of the composite crusher are: (1) simple and reasonable structure, low operating cost. By utilizing the principle of stone to stone, there is minimal wear and tear. (2) High crushing rate and energy-saving. (3) It has the functions of fine and coarse grinding. (4) Less affected by the moisture content of the material, with a moisture content of up to 8%. (5) The working noise is below 75 decibels (dB level), and there is less dust pollution. (6) Suitable for crushing medium hard and extra hard materials. (7) The product is cubic in shape, with a high packing density and minimal iron pollution. (8) The self lining of the impeller has minimal wear and is easy to maintain.
Product Description
1、 Purpose:
The series of vertical composite crushers is a straight through adjustable fine crushing equipment developed by our company's technicians based on market demand and advanced fine crushing equipment at home and abroad. This equipment can be widely used in the cement, refractory materials, building materials, and artificial sand industries for fine crushing operations of medium hardness stones such as limestone, river pebbles, dolomite, blast furnace slag, coal mine stones, refractory materials, etc. Especially suitable for the processing and crushing of artificial sand and stone materials for highway pavement.
2、 Characteristics:
This equipment has a high crushing ratio and high crushing moisture content, making it ideal for processing materials with high moisture content. The discharge particle size can be adjusted arbitrarily, and there is no screen strip setting. Materials with high mud content will not be blocked, and non crushable materials can be automatically discharged from the body without causing equipment damage. This equipment crushes materials with direct current, high production efficiency, unique structure, smooth operation, no noise, easy maintenance, and can easily replace vulnerable parts by opening the work compartment door
