What Is The Difference Between A Hammer Crusher And A Roller Crusher?Hammer crushers and roller crushers are commonly used crushing equipment in mining, building materials, and other industries. They exhibit significant differences in working principles, suitable materials, and discharge characteristics. As a renowned domestic manufacturer of crushing equipment, Huashengming offers products with distinct advantages in both types of machinery. 1. Core Differences Comparison Comparison Dimensions Hammer Crusher Roller Crusher Working Principle High-speed rotating hammers impact the material, supplemented by shearing and grinding. Two rollers rotate in opposite directions to compress the material, primarily relying on hydrostatic crushing. Suitable Materials Medium-hard brittle materials (limestone, coal gangue, gypsum), compressive strength ≤100 MPa, moisture content <15% Medium-hard materials (river pebbles, granite, coal) with compressive strength ≤160 MPa and moisture content ≤35% remain operational. Feed Particle Size Large (600–1800 mm) Smaller (≤40–150 mm) Discharge Characteristics Particle size is uneven, prone to over-grinding (high powder content) Particle size is uniformly controllable (adjustable from 1–20 mm), with a high proportion of cubic particles and low over-grinding rate. Output and Energy Consumption High production capacity (up to 3,000 tons per hour), relatively high energy consumption per unit Medium output (5–400 tons/hour), with energy consumption per unit reduced…
Huashengming Gold Crusher (primarily a roller crusher) operates on the principle of dual-roller compression crushing combined with shear tensile action. By adjusting the roller gap, it precisely controls the output particle size, making it particularly suitable for high-moisture, sticky materials like clay-bearing gold ore. Below is a detailed analysis of its core working principle: 1. Core Crushing Principle Dual-Roller Compression Crushing Material enters between two counter-rotating rollers via the feed inlet. Hydraulic or spring systems compress the rollers, exerting intense squeezing force on the material. High-hardness toothed structures on the roller surfaces (e.g., toothed roller design) further enhance shearing and tensile forces, efficiently fracturing gold ore at its weak points. Synergistic Shear and Tensile Action Unlike traditional impact crushers, Huashengming equipment employs a low-speed, high-torque transmission system. This causes the material to undergo impact shear forces and impact tensile forces within the roller tooth gaps. Shear forces concentrate at the joints or fractures within the ore, significantly boosting crushing efficiency. 2. Particle Size Control Mechanism Dynamic Roll Gap Adjustment Output particle size is regulated by adjusting the gap between the two rollers: Increasing gap → Larger output size (e.g., 5-40mm); Decreasing gap (via spring or hydraulic compression) → Smaller output…

The double-tooth roller coal crusher is a crushing device specifically designed for medium-hardness brittle materials such as coal, coke, and coal gangue. It achieves efficient crushing through the squeezing force and shearing force generated by the relative rotation of the two rollers. The following are its core characteristics and technical points: 1、 Core Structure and Working Principle 1. Structural Composition Crushing Rollers: Two parallel toothed rollers (fixed roller + movable roller), with roller surfaces made of high-chromium alloy or tungsten carbide overlay welding for wear-resistant tooth profiles (e.g., wolf teeth, spiral teeth). Overload Protection: The movable roller is equipped with a spring or hydraulic cushioning system, which automatically increases the roller gap when encountering hard objects like iron blocks to protect the equipment. Adjustment System: A hydraulic or mechanical device precisely controls the roller gap (0.5–30 mm) to adjust the output particle size. Drive System: Motor → hydraulic coupler → reducer → gear transmission, ensuring synchronous counter-rotation of the dual rollers. 2. Working Principle Material enters the V-shaped crushing chamber and is crushed by the squeezing and shearing action of the dual rollers; qualified particles fall through the roller gap, while oversized material is returned by the toothed rollers for…

What is a roller crusher? Roller crusher (also known as double-roller crusher, roller sand making machine) is a kind of mechanical equipment to achieve crushing through two oppositely rotating rollers to squeeze the material, mainly used for medium and fine crushing of medium-hardness materials (such as limestone, coal, pebbles, etc.), is widely used in the cement, metallurgy, chemical industry, electric power and building materials and other industries. 1. Core structure and working principle Basic structure Roller: the core working part, divided into fixed rollers and movable rollers, the surface can be designed as smooth or toothed (toothed roll crusher), the material should be wear-resistant. Adjustment device: Adjust the gap between the two rolls (0.5-50 mm) by wedge or shim to control the granularity of the material (e.g. if the wedge is moved up and the gap is increased, the material will become coarser). Driving system: double motor drive, through the triangle belt to drive the roller reverse rotation, some models are equipped with hydraulic spring overload protection device. Auxiliary components: support bearings, safety cover, iron removal device (to prevent damage to the roller by metal foreign objects). Working Principle The material falls into between the two rollers from the inlet,…
Roll Crusher High Humidity Material Solution Roll crusher is prone to sticking rollers, clogging, uneven discharging and other problems when dealing with viscous materials (such as clay, wet coal) or materials with high moisture content (moisture content >15%). The following are the specific operation techniques and optimisation solutions combined with industry practice: 1. Pre-treatment and feed control Moisture regulation and control Drying pre-treatment: For materials with moisture content > 20%, priority is given to drying equipment (such as drum dryer) to reduce the humidity to less than 15%. Mixing of wet and dry materials: Mix wet materials with dry materials (e.g. dry coal, limestone) in the ratio of 1:1~1:2 to reduce the overall viscosity. Heating assistance: add hot air device (temperature 80~120℃) at the feeding port to evaporate the surface moisture and reduce the adhesion. Optimisation of particle size and feed Pre-screening: Pre-screen the large materials (>300mm) to avoid jamming or roller gap extrusion splash. Uniform feeding: adopt frequency conversion feeder to control the flow rate, avoid instantaneous overloading and blockage (suggested feeding speed ≤ 80% of the rated value). 2. Equipment parameter adjustment Roll gap and pressure adjustment Expand the roller gap: for high viscous materials (such as plasticity…
