Equipment Introduction

Horizontal Crusher is a general term for crushing machinery in which all rotor shafts are placed horizontally and rotate at high speed around a horizontal axis to crush materials. As a major category of crushing machinery, horizontal crushers have a wide range of applications, including hammer crushers, ring hammer crushers, impact crushers, chain crushers, cage crushers, and many other types.

Compared to vertical crushers, horizontal crushers have significant advantages in that they have a longer crushing working section and can crush finer particles. Materials move linearly in the horizontal structure and are crushed at high speed. Combined with an open discharge, this results in higher crushing output. The structural characteristics of horizontal crushers are high production capacity, low energy consumption per unit product, and a large crushing ratio. They can replace multi-stage crushing, completing the entire product production process from coarse to fine crushing.

Horizontal crushers can be classified into several types according to their crushing method, such as chain crusher, hammer crusher, and blade crusher. According to their application and fineness, they can be classified into coarse crushers, fine crushers, and ultrafine crushers. According to their crushing principle, they can be classified into impact crushers, shear crushers, and airflow crushers.

This equipment is widely applicable to various industries such as organic fertilizer, compound fertilizer, chemical, feed, food, medicine, building materials, and mining. It is a highly versatile crushing equipment.

Equipment Structure

The structure of a horizontal pulverizer varies depending on the type, but it generally consists of the following main parts:

Applicable Raw Materials for the Equipment

The horizontal pulverizer has a wide range of raw material adaptability, mainly including the following categories:

1. Organic Fertilizer Raw Materials

Livestock and poultry manure (chicken manure, pig manure, cow manure, sheep manure, etc.)

Grass peat, rural straw waste, industrial organic waste

Mushroom residue, biogas residue, kitchen waste

2. Feed Raw Materials

Corn, wheat, rice, oats, sorghum, soybean meal, and other grains

3. Chemical Fertilizer Raw Materials

Compound fertilizer lumps, superphosphate, nitrogen fertilizer, potash fertilizer, etc.

Phosphorus fertilizer with moisture content <14% and free acid content <6%

4. Chemical Raw Materials

Foaming agents, white carbon black, carbon black, phenolic resin, surfactants, etc.

5. Mineral Raw Materials

Calcium carbonate, bentonite, talc, kaolin, graphite, and other non-metallic minerals

6. Other Materials

Wood blocks, bamboo, fruit shells, traditional Chinese medicine, bark, leaves, etc.

Plastics, paper, circuit boards, etc.

7. Moisture Content Requirements:

Standard Horizontal Crusher: Moisture content less than 10%

Special Model for Semi-Wet Materials: Can handle high-moisture materials with a moisture content of 30%~40%

Horizontal Chain Crusher for Fertilizer: Can handle materials with a moisture content of 14%

Working Principle of the Equipment

The material is fed uniformly into the sealed grinding chamber via a variable frequency quantitative feeding system. The high-speed rotating grinding disc generates a powerful impact force, which, combined with the shearing, friction, and airflow impact of the toothed ring, instantly completes the ultra-fine grinding of the material. The ground material then enters the grading zone with the high-pressure airflow. The variable frequency grading rotor precisely filters the particle size. Qualified fine powder is collected by a cyclone collector with the airflow, while trace amounts of dust are purified by a pulse dust collector. Coarse particles are intercepted by the grading rotor and automatically returned to the grinding chamber for secondary grinding. The entire process is a closed-loop operation with no dust leakage and precise controllable particle size.

Equipment Operation and Maintenance Methods

Operating Procedures: Strictly adhere to GMP operating standards. Before starting the machine, thoroughly clean and disinfect the equipment cavity, pipelines, and collection devices; preheat the machine under no-load for 3-5 minutes and calibrate the grading speed; adjust the feeding speed and grading parameters according to the material characteristics, and prohibit overloading; after operation, empty the entire machine of materials, complete disinfection and cleaning, and keep accurate equipment operation records.

Maintenance Methods: Clean the cavity, air ducts, and filters daily, and check the operating status of the grading rotor; check the fan pressure, bearing lubrication status, and seal sealing weekly to prevent dust leakage; calibrate the grading accuracy and motor speed monthly, and check the wear of the crushing disc and gear ring; replace the dust collector filter and aged seals quarterly, and calibrate and adjust the overall machine accuracy.

Common Equipment Problems and Solutions

Applications of the Equipment in Production Lines

It is primarily used as a core pre-processing device at the front end of the production line, connecting to feeders and conveyors, and then connecting to screening machines, mixers, granulators, packaging machines, and other equipment at the rear end. In organic fertilizer production lines, solid waste treatment production lines, biomass fuel production lines, and ore fine crushing production lines, it undertakes the coarse crushing, fine refining, and dispersing of raw materials, providing uniformly sized raw materials for subsequent fine processing and ensuring the stable and efficient operation of the entire production line.
