V-belt tensioning and pulley alignment
Drive belt tension and pulley alignment decide the vibration level of a crusher and the working life of its bearings. This guide gives the deflection method for measuring tension, separates angular from parallel misalignment, covers re-tensioning after run-in and sets the order of the adjustment.
Heavy-Duty Mobile Crushers for Marble Quarries and Mines
In marble quarries and mines, crusher selection starts with the truck cycle and the geometry of block waste; portable primary units moved towards the face shorten the haulage chain. M-PDK impact for clean calcitic material, GNR jaw for abrasive or metal-contaminated waste and a wobbler-fed jaw for clayey stripping are logical starting points.
Using Mobile Crushers for Construction and Demolition Waste (Concrete Recycling)
Whether mobile crushing of demolition waste pays off depends on on-site versus central processing, separating piles through selective demolition and where the product will be used. A crusher bucket suits small jobs, a portable impactor with by-pass screen suits medium volume, and a mobile crushing and screening plant suits continuous work needing saleable fractions.
The Ideal Mobile Crushing Plant Configuration for Road Construction and Sub-Asphalt Material
A mobile crushing plant for road work is configured backwards from the specified layer: jaw-cone, jaw-impact or primary impact stages by rock type, screen decks that set the number of fractions, and relocation along the route. Crushing capacity is balanced against the mobile plant-mix unit through stockpiles; grading acceptance depends on the project specification and sieve tests.
Aggregate fraction balance stockpile planning
Capacity full, tonnage on target, profit still short: the most common reason is that the fractions produced do not match the fractions sold. This article covers writing the demand profile fraction by fraction, measuring the production profile, the levers that close the gap, and the rules that keep a stockpile honest.
Choosing a Mobile Crusher for River-Bed Aggregate Production
For river material, machine choice starts not with tonnage but with whether the material needs crushing, washing or only screening. Sample tests point to the right setup among the ME1650, YM1240/YM1650, Mobil 90 and GNR-MVSI 900.
Performance and Energy Analysis of Electric and Diesel-Hybrid Mobile Crushers
In an electric mobile crusher, energy cost is set by the source feeding the motors — grid or generator — not by the motors. This article separates four drive architectures, reads the kVA/kW data on General Makina models and compares both sources with a cost-per-tonne formula.
Mobile Screening Plant or a Crushing and Screening Combination?
If most of your material is already below 100 mm and clean, a mobile screening plant without a crusher (GNR ME1650, ME2060) is enough; blasted quarry rock or deposits with a high share of oversize need a crushing and screening combination. The decision is driven by feed size, oversize share and rock abrasiveness rather than by hourly capacity.
High-Efficiency Mobile Crusher Solutions for Limestone
In limestone, efficiency is won through grizzly pre-screening, a blow bar alloy matched to the quarry, apron gap control and PLC-balanced feeding. The General 800, 01, 02, 03 and M-PDK options are chosen by tonnage, lump size and existing line.
The Best Mobile Crushing Plant for Hard, Abrasive Rock (Basalt, Granite)
For basalt and granite, choosing a mobile plant starts with the rock's abrasiveness, the largest block and the product specification, not with tonnage. Jaw + cone General 944 suits granite, General 950 suits basalt where cubicity leads, GNR-MC110 high tonnage and the tracked GM 90JP a face-following primary.
Quarry Capacity Planning Annual Production Target
An annual tonnage target is not simply divided by hours. Working days, shift hours, availability and utilisation are applied in sequence, and the effective hours that remain give the nominal capacity required, which the seasonal peak month then pushes upward.
Choosing the Crusher Type for a Crushing Plant: Jaw, Impact and Cone Crusher Differences
Crusher type is chosen through the stage chain, where primary output must fit secondary input, not machine by machine: the jaw is the primary, while cone and impactor compete for the second stage. In abrasive rock a jaw + cone line leads; in limestone and under strict particle-shape specs an impact configuration does.
Tracked Mobile Crusher or Towable Semi-Mobile Crusher?
A tracked crusher suits work that relocates often within a site on difficult ground, while a towable semi-mobile plant suits work that moves between distant job sites and stays long at each. Relocation count, crushing circuit scope and ground decide the choice before crusher type does.
100 TPH, 200 TPH and 350 TPH Mobile Crusher Capacity Selection Guide
100, 200 and 350 t/h are three different operating classes: feed opening, power unit, number of chassis and loading equipment all change together. This guide shows, with data from the product pages, which General Makina mobile model runs comfortably in each class and which one runs at its limit.
Rent or Buy? Mobile Crusher Cost Comparison for Construction Sites
Renting a mobile crusher looks easy for a short one-off job, but as crushing months per year grow, rent quickly overtakes the cost of ownership. General Makina does not rent machines; for a contractor with continuous work the right choice is to buy a new machine, and a used one does not change that calculation.
Stockpile and haul road dust management
The plume that ends up in an inspection report usually rises from a road or a windswept pile, not from the crusher. This guide organises watering frequency, speed, fence porosity and drop height into a workable plan.
100 TPH Mobile Crushing Plant Price and Investment Payback (ROI) Period
A 100 t/h target lands at different points on the General 640, General 800 and GM 100, and the quotation is shaped by crusher layout, undercarriage, screen, generator and delivery scope. Payback equals total investment divided by annual net cash flow and depends most on net crushing hours and contribution per tonne.
Mobile Crushing Plant Hourly Fuel Consumption and Operating Cost Calculation
On a mobile crushing plant, hourly fuel consumption is set by the average load drawn from the generator, not its kVA rating, and it can only be measured reliably on site with the top-up method. Once fuel, wear, labour, depreciation and transport are placed in a formula and converted to cost per tonne, holding tonnage turns out to be the deciding factor.
7 Financial Criteria When Buying a Mobile Stone Crushing Plant for Sale
The financial value of a mobile stone crushing plant comes not from its price tag but from cost per tonne, built from capacity fit, wear, energy, transport, product revenue, warranty and growth path. Comparing the seven criteria in one table and buying a correctly sized new plant always pays better than the hidden costs of a used machine.
Mobile Crusher Prices 2026: New vs. Used Plant Cost Guide
A mobile crusher price is set by scope, not by model name: crusher layout, screen decks, generator and conveyors, so quotations must be compared on equal scope. The low asking price of a used plant melts away with overhaul, downtime and no warranty; on total cost, a new machine is always the right choice.
Crushing Plant Working at Height Platforms Guardrails and Access
Fall risk on a crushing plant concentrates on the screen deck, around the crusher feed opening and on conveyor walkways. This article gathers guardrail height, knee rail and toe plate dimensions, stair inclination classes and the anchor point decision into one reference.
Annual operating cost budget crushing plant teams can actually use
An operating budget is not one cost per tonne. Energy, wear, lubricants, labour, insurance and lost production each belong on their own line with their own measurement base. This article sets out those lines and shows which monthly deviation signals which problem.
Supplier factory audit and pre-shipment inspection
The audit tests the maker's system, the inspection tests what goes in the crate. Without a weld quality level, coating readings, nameplate checks and a no-load record, acceptance is only an impression.
Urban jobsite mobile crusher operating plan
On an inner-city site the limit is rarely crushing capacity. Manoeuvring room, the permitted working window and the neighbour relationship set the pace, and the plan has to be built around those three.
